Detaching the keyboard
Continuing disassembly requires turning the laptop over and examining the keyboard. It can be detachable or fixed in the housing. Detachable keyboards are more common. They can be identified by the visible gaps between the case and the buttons. It is recommended that you use a spatula or pick to detach the keyboard. You need to go around the keyboard around the perimeter and snap off each mount. Take your time and put too much effort. The latches are quite fragile and can simply break. If after the first time the keyboard is NOT removed, you need to repeat the procedure until any obstacle is removed.
Sometimes manufacturers equip the keyboard with a special outer frame. In this case, you first need to remove it, and only then do the keys. The keyboard is connected to the motherboard with a ribbon cable, which must be carefully separated.
Once the keyboard is removed, the top cover is accessible. Unscrew it to get to the motherboard. The back of the motherboard will be revealed.
Applying thermal paste and reinstalling the heatsink
Now you can start applying thermal paste. A small droplet of the substance is applied to the processor through a special dispenser. The next question is: how much does it apply? Too much can negatively affect the cooling system and the performance of the device as a whole.
Spread the thermal paste evenly over the entire surface of the chip. This can be done with a bank card or something similar. It is recommended to avoid getting thermal paste on other components of the laptop. As soon as the paste is applied over the entire surface, it will penetrate into all micro-crevices and begin to function.
The next step is to install the radiator. Mounts above the processor. And again you need to take a closer look at the numbers near the mounts. Screws Must be tightened in a specific order from the lowest number to the highest. This is the only way to avoid uneven processor load. Together with the radiator, the cooler is also installed in place.
Separating the main body parts
After all Possible components have been separated from the motherboard, you can start separating the laptop parts. The upper part is fixed to the lower one with latches. The same tool is used as when removing the keyboard: a paddle or a pick. You need to walk around the entire perimeter and snap off all the fasteners. Everything is done as carefully as possible and without haste. Broken latches will cause the case to stop being airtight and quickly pick up dust. Not to mention the aesthetic properties of an incompletely closed laptop.
Once all fasteners are released, the top of the laptop can be removed. Now it becomes possible to remove the motherboard and carry out proper maintenance of the cooling system.
How often do you need to change the thermal paste in a laptop
Usually, replacing thermal paste is a forced procedure that is a response to obvious malfunctions in the device. Excessive overheating, noise, and excessive dustiness are considered the main symptoms. Each of THESE symptoms can lead to the development of much more serious problems. Therefore, it is recommended that you simply do not prove the laptop to such a state. This is done through timely scheduled maintenance with replacement of thermal paste and cleaning the cooling system.
How often and where should the thermal grease be changed? Manufacturers recommend carrying out maintenance at least once a year. You can service the device yourself or take it to a service center. If you have doubts about your own knowledge, experience and care, then it is better not to risk it. Qualified specialists of the service center will promptly service the laptop with a very small amount.
Well, do not forget about the prevention of contamination of the cooling system. DO NOT use the laptop on a blanket or other soft surfaces. Not only can the air access be blocked, but also various fluff from the fabric will get into the laptop.
Dismantling the casing segments
Next, you should disconnect all the housing segments, which are attached separately. This includes all rear covers that provide access to certain components. Usually, manufacturers in this way simplify access to RAM, hard drive and Wi-Fi adapter. If, after removing the covers, access to these components opens, they must also be pulled out. Wi-Fi adapter must be disconnected from the motherboard, and then unscrew the retaining screws.
RAM is attached to special latches. They need to be bent and carefully pull out the strips. By the way, pulling out the OPG is NOT a mandatory procedure and is recommended only for those laptops in which memory sticks can interfere with further disassembly.
The hard drive is mounted in a specially designed recess. Usually, simply pulling on the disc and pulling it out of its slot is sufficient. But sometimes manufacturers anticipate additional fastening of the disk to the case using screws.
Sometimes at this stage it becomes possible to remove the drive. It is pulled out from the side, along with a special outer panel. Most laptops do NOT anticipate specific drive mounts.
Cleaning and lubricating the fan
Now you can start directly servicing the cooling system. The first step is to inspect the fan. In heavily operated devices, it can be very dusty, and there is insufficient lubrication in it. All this leads to difficulty in rotation, noise or complete inoperability. Service begins with cleaning the fan from dust. It is carried out best of all with a thin brush. Airflow will not be superfluous.
Once the fan has been free of dust, it is always recommended to Lubricate the component. This is done through a special hole or after disassembling the fan. This completes the fan service and in most cases its performance is restored. If the problems are much more serious than expected, the fan needs to be changed.
Disconnecting internal device connectors
All laptop components are connected to the motherboard. At this stage, you need to disconnect all Possible connectors so that nothing will interfere with the opening of the case. All indicators, additional buttons and other devices are attached with wires. Each of them is removed from the corresponding groove. It is recommended to sketch the location of certain connectors. This will help to avoid assembly errors and possible problems in future work.
Blowing off the radiator and removing residual traces of thermal paste
Next comes the radiator service. It needs to be properly blown to remove all the dust accumulated inside. Mechanical cleaning with a brush may also be required. But the most important issue for the radiator is the removal of the old thermal paste from the surface in contact with the chip. The procedure can be performed using alcohol. You need to carefully remove all leftovers with a napkin or Cotton pad. But you need to make sure that there are NO fibers left on the surface. The radiator is cleaned to achieve a mirror finish near the surface. Any serious mechanical stress must be avoided. Any scratch can negatively affect the heat transfer efficiency.
Old thermal grease should be removed Not only from the heatsink, but also from the chip itself. In this case, you need to act even more carefully, since the processor is very sensitive to any influences. The chip at the end of cleaning should not have any traces of thermal paste.
Replacing thermal paste in a laptop
Long and intensive use of the laptop inevitably leads to the need for maintenance. It manifests itself in frequent freezes, overheating and similar symptoms. Overheating is a problem for the vast majority of laptops.
Too small dimensions to install a full-fledged cooling system force the use of mobile designs. After a while, the cooling ceases to function normally and to fulfill its duties. To fix this problem, you need to disassemble the laptop and carry out maintenance of the cooling system, which directly includes replacing the thermal paste on the chips.
Thermal grease is a substance that provides the maximum surface area of contact between the chip and the cooling element. This is to maximize heat dissipation from the main components of the laptop. How do I properly change the thermal paste on my laptop? The answer to this question is contained in the article.
The sequence of actions when replacing thermal paste
You can change the paste only after disassembling the laptop case. At this stage, great care must be taken not to break the fragile plastic parts. This is done in the following sequence:
- Remove the laptop battery. You may need a screwdriver for this.
- In accordance with the instructions for the device Remove the back panel from it, clean the surfaces from dust.
- Use a napkin to remove old thermal paste from the processor and heatsink surfaces. Old thermal grease for laptops often dubs. use alcohol to soften it. But after that, the surfaces to be treated and the motherboard must be thoroughly dried. A regular eraser also works well even with dried paste.
- Apply a coat of new thermal paste to the Cleaned processor surface. It should come out with a uniform thickness of only a few microns. You cannot level a layer with just your finger. There is fat on the skin, the penetration of which into the paste can significantly reduce its thermal conductivity. To apply a thin layer as a kind of “spatula” it is better to use a plastic thin card or something similar. It is necessary to change the thermal paste in two stages:
- Squeeze a small amount of paste from the tube onto one side of the processor;
- With a credit card I will smear it on the surface with a thin even layer.
At the final stage of assembly, it is important to correctly mount the cooling radiator. Make sure that when it comes into contact with the processor, the thermal paste does NOT squeeze out. This is possible if it was applied too thickly. In the future, when carrying out the procedure for cleaning the laptop from dust, Do not forget to pay attention to the condition of the thermal paste. When it dries, the processor will quickly fail.
To replace the thermal paste, we need
- Knife, I prefer to use clerical.
- Dry wipes or toilet paper. It will be necessary to clean the processor, and you will smear your hands in thermal paste.
- Thermal paste. For a laptop, there is a critical difference in the quality of thermal paste, you can use the cheapest KPT-8. I am using Arctic Cooling MX-2.
It is necessary to remove the back cover, cooler and clean the dust. These actions are detailed in the article, the laptop turns off by itself.
Attention, if you doubt your skills, it is better not to try to change the paste on the laptop yourself, trust the professionals. Here it will perfectly cope with this task.
The first step is to unscrew and remove the back cover of the device. It is important to understand that doing so will void your laptop warranty. Disconnect the device from the mains, pull out the battery and loosen the bolts. Try not to lose the bolts, so that after the procedure, return everything to its place.
After removing the cover, you will see all the “insides” of the laptop. Most of all we are interested in the video card. In most cases, the developers screw it with 4 bolts and press it against the radiator. Unscrew the bolts, carefully pull this component out of the connector.
The next step is to clean the chip and heatsink from the old thermal paste. Experienced users say that the opposite effect can be achieved if the thermal paste is applied incorrectly. As you can see, this is not the case when you cannot spoil porridge with honey. Applies the product to a previously cleaned, grease-free surface (use a utility knife to remove old material).
To prevent overheating of the devices, it is advisable to get rid of the dust accumulated during use inside. Gently brush over the laptop to remove dust. It is she who is the main enemy of technology: clogging up in slots and corners, it interferes with the spinning of coolers and cooling the device.
Collect the laptop in the reverse order:
- Screw the video card back to the radiator;
- Installing the back cover;
- We insert the battery;
- Connect the device to power.
Replacing thermal paste in your laptop
Admin | December 20 2014 | Miscellaneous |
A couple of days ago I decided to change the thermal paste in my laptop, and there were several prerequisites for this: 1 I last replaced the thermal paste more than a year ago,
2nd in critical operating modes, the processor temperature kept pace with 100 0С.
Do not look at the fact that I know the very permissible temperature of my processor is 105 ° C, I did not wait until it starts to shut down, reduce the operating frequency or simply burn out.
The first thing I would like to say to those who are going to change the thermal paste on their own. think about it, is it worth it, what am I for. replacing thermal paste is not the most difficult process, but disassembling a laptop is another matter. if a person is not sure whether what he does or. As the saying goes “hands do NOT grow from there”. give it better to specialists, it will be cheaper
With regard to desktop PCs, things are easier there. Of course, crooked hands and a head will be able to do something bad there, but the probability is much less. Enough prefaces. let’s get started.
Before disassembling the laptop, I went online and found a video. actually, how my laptop is disassembled. At the moment, the vast majority of models are freely available, so there should be no problems with this.
After I knew exactly what to disassemble and for what, I got down to work. In this case, the main thing is not to rush, carefully, slowly and everything will work out for you. A few tips. We put the bolts and other parts of the laptop, in different places, so that when the time comes to assemble, and it turns out that you have one big pile of parts and different bolts, and you just do not remember what is where and for what! And put the thermal paste either on the battery or in the sun. why? The higher its temperature, the easier and more evenly it will be applied to the processor surface. As long as you take apart your laptop or computer, it will already be warm enough.
3.Very carefully disconnecting all connectors and cables, no effort is needed there, everything is removed quite easily.
In order to clean the cooler, you will most likely have to remove it. It often comes complete with a cooling system. There is one point here, the bolts of the cooling system must be unscrewed sequentially, from a larger figure to a smaller one, for example: 6,5,4,3. Thermal paste could have dried a little to the surface of the processor and video card, so it is necessary to disconnect the cooling system from the laptop carefully enough.
Clean the cooling system. A brush and a vacuum cleaner are best suited for this. My laptop was operated in rather harsh conditions, but I always worked in clean rooms and only on clean surfaces, and even this is enough for the cooling system to be covered in dust.
After the entire system has been removed, it is necessary to clean the surface on the processor and cooling heatsink. It is best to use cotton wool and alcohol, you can carefully remove the layer of the old paste with a plastic card, but in no case with metal objects. you can damage the processor. It is necessary to clean until the surface is already perfectly clean and even.
7.Now we apply a layer of new thermal paste, it should be quite thin and uniform, not thicker than 0.5 mm. (Ideally even less, but this is quite difficult to achieve). Do not put one big drop inside the site, and then press it down by tightening the bolts on the radiator. with this installation method (if the thermal paste is thick) you will NOT get a uniform layer.
Then put the cooling radiator in place and tighten the bolts, now in the correct sequence, i.e. 1,2,3,4,5. Putting the whole laptop back, the main thing is NOT to break anything and do not forget to connect all the contacts and cables. That’s probably all, nothing complicated.
Replacing thermal paste on a laptop
- We unscrew the bolts securing the radiator and remove it. You need to unscrew in a strict sequence indicated on the radiator itself.
- First, pull the metal socket pedal to the side and then lift it up. The socket will slightly “move”, as it should be.
- After the socket pedal is in an upright position, take the processor by the sides and remove it from the socket. Always hold the processor only by the sides, the legs are strong enough to put it on a plane, but bend when pressed, be careful.
- Now, using a knife and toilet paper, Remove the remnants of the old thermal paste from the heatsink and processor.
- Apply some thermal paste to the processor and use a knife to spread it evenly over the entire surface of the processor. It is not necessary to apply thermal paste to the radiator.
- We insert the processor into the socket. Pay attention to the processor, one of the corners is marked with a golden arrow, this corner must coincide with the corner of the socket, also marked with an arrow.
- Lower the socket pedal.
- We install the radiator and twist it in the specified order.
Replacing thermal paste on a laptop
Composition, properties and features of the choice of thermal paste
Its multicomponent composition includes fillers from microdispersed powders of metals and their oxides, and synthetic and mineral oils are used as a binder.
Let’s list the well-proven brands of thermal paste:
- Titan silver grease,
- Cooler master.
The main property of thermal paste for laptops is its high thermal conductivity, much better than in air. Therefore, when a layer of this material is applied to the junction of the processor and heatsink, the normal temperature regime of the laptop is ensured. Without thermal paste or with an old “hardened” substance, the processor will simply burn out.
A signal to change the old thermal paste may be Severe overheating of the laptop processor, even with a low load.
You can choose both domestic brands (KPT-8 and AlSil-3) and foreign ones. According to their characteristics, they are identical, but imported ones are somewhat more expensive. An additional advantage of domestic pastes is the relative ease of their application, since the latter have a more liquid consistency.
If desired, the thermal paste recommended by the processor manufacturer can be found on its website. Usually, the results of tests and tests of various pastes are laid out there, specific recommendations are given on how to change them and choose the composition. Also try to purchase exceptionally high-quality replacement materials, avoid too cheap ones, as they may turn out to be fake.
Make sure that the composition of the paste is completely homogeneous. the presence of lumps and foreign substances in it is unacceptable, as air gaps can form, which worsen the thermal conductivity.
Preparing for replacement
To replace the thermal paste correctly, you will need the following materials:
There are several methods to reduce the heating of the video card. The most popular is the purchase of a special stand. According to experts, it does not help the business much. the temperature drops as much as possible by 2-4 degrees. Another method is to update the video card firmware (BIOS). Only specialists are allowed to use this option, because in the absence of certain knowledge, you can permanently disable the video chip.
An alternative to the methods described above is the replacement of thermal paste between the heatsink and the chip. With the help of a special substance, you can lower the temperature to 11 degrees!
The task of thermal paste is to conduct heat between the heatsink and the chip, compensating for the unevenness of both surfaces.
How to replace thermal paste: simple instructions that will extend the life of your PC
When the thermal paste dries, the computer gets very hot, and the processor and video card may fail.
Thermal paste is a thick substance, usually white or light gray. Its most important property is its high thermal conductivity. Therefore, thermal paste is applied to the central processor and the video card chip so that these heated elements better give off heat.
Over the years, thermal paste dries up, which often leads to overheating of the computer. If the temperature of the processor and video card in your PC rises above the permissible level and the heat-conducting composition has NOT been updated for several years, then you need to act. The service center will gladly replace the thermal paste for money. But you can also do it yourself and save money.
Remove the remnants of the old substance
Take a dry cloth and carefully remove the old thermal grease from the processor, video card and cooling elements. If the substance does not yield, soak a cotton swab with a little alcohol and try to remove the residue with them.
Prepare everything you need
Which paste to choose is a Discussion question. There are some large-scale studies on the effectiveness of thermal paste on the web. But service centers often recommend the Zalman, Noctua and Arctic brands. A syringe with four grams can be purchased for 300-400 rubles. This should be enough for several replacements.
In addition to thermal paste, you will need:
- A screwdriver for disassembling a computer;
- Dry paper towel, cotton swabs and alcohol to remove the remnants of the old substance and the surplus of the new;
- Vacuum cleaner for cleaning from dust (preferably);
- Plastic card or brush for applying new thermal paste.
Apply new thermal grease
Squeeze a drop of thermal paste from the syringe onto the processor and spread the substance in a thin, even layer over the entire area of the plate. To do this, use a brush if it was sold as a set, or a plastic card, or any suitable item. The main thing is that it is dry and cannot scratch the processor. If the substance gets outside the plate, wipe it off with a paper towel.
To replace thermal grease on an integrated or external video card, apply the substance to its chip in the same way as on a processor.
You can apply thermal paste to both the chip itself and the heatsink (see video). Or you can do with just a chip: that will be enough.
Let’s disassemble the computer
Turn off your computer and unplug the power cord. Then remove the housing cover with a screwdriver.
At this point, it does NOT hurt to gently vacuum the inside of your computer. Having got rid of the dust, you lower the overall temperature of the system. But don’t overdo it: the vacuum cleaner should NOT touch any parts.
After unscrewing the bolts on the cooling system, disconnect it from the motherboard. you will see a metal plate under it with the remnants of the old thermal paste. This is the processor. There may be another plate next to it. a chip of an integrated video card.
It happens that the laptop case interferes with the separation of the cooling system from the motherboard. In this case, you will first have to pull the motherboard out and only then disconnect the radiator from it, as in the video example above.
If your computer has a separate video card with its own cooling, remove it, and then remove the heatsink from it. Under it on the video card there should also be a plate with the remnants of the old substance. a video chip.
If you have any difficulty disassembling your computer or SEPARATE components, search YouTube for a video of servicing the same model as yours.
Assemble your computer
After replacing the thermal paste, reinstall all components. Make sure they are secure and you don’t miss a single bolt. Then close the housing cover.
Turn on the computer and observe the temperature of the processor and video card. If its average value falls, then the replacement of thermal paste went to the benefit of the devices. In case of failure, consider other causes of heating.
Replacing thermal paste on a laptop
The process of replacing thermal paste on a laptop is as follows:
- Unplug laptop, unplug power cord, remove battery.
- Unscrew all the bolts, remove the back cover.
- Remove dust, remove with a cotton pad or a cloth dampened with alcohol, old thermal paste.
- Apply a thin layer of fresh thermal paste to the processor and video chip.
- Check if there is a surplus.
- Assemble the laptop.
Here is a clear understanding of how to apply thermal paste to the computer processor, the further performance of the entire device depends. When applying thermal paste to the video chip and laptop processor, remember. a thick layer is by no means better. Very little paste is required; you can evenly distribute it with your finger, or with a special spatula, credit card or discount card. But in no case in a thick layer: otherwise the laptop will continue to overheat.
How to change thermal paste on your computer and why you need it
09 October 2017
Thermal paste is a special heat-conducting compound designed to improve the heat-conducting characteristics between the heating elements and the radiator grill. It is a viscous substance that can be practically liquid. The main characteristics of the thermal paste:
- Thermal conductivity;
- Resistant to high temperatures;
- Non-flammability and safety for human health;
- Corrosion resistance;
- Maintaining consistency.
A good composition does NOT spread, and does not dry out instantly and is applied without problems: you do not need to get an engineering education to understand how to change thermal paste on a computer. It can also be easily removed with a regular cotton pad or a cloth dipped in alcohol. The consistency of the paste does not have to be too liquid: otherwise it will simply spread. Too thick and viscous paste, on the contrary, will NOT lie flat when applied.
It is recommended to choose fresh thermal paste from reliable manufacturers. Old and low-quality Will not meet the main characteristics, will not fit well and will NOT do what the thermal paste is for in the computer. The processor will overheat and the device will NOT function normally.
Thermal paste analogs
- Thermal pads (they are also thermal interfaces)
- Thermal gum.
Thermo gum is the same paste, only very thick, and not spreading. The name came from precisely because of the similarity with gum. Using a paste or gum is a matter of personal convenience.
The thermal pad is a silicone interface that performs the same function. In some cases, it is more convenient to use it, rather than bother with erasing and spreading the thermal composition. If there is such a large gap between the processor and heatsink that it is difficult to fill it, you can install a gasket. But it should be borne in mind that its heat-conducting characteristics are lower, although the service life is much longer.
Replacing thermal paste on a desktop processor
The procedure for replacing thermal paste on a stationary computer processor is not the most difficult task, but it requires certain knowledge and skills.
- Disconnect the heatsink from the motherboard.
- Disconnect the processor from the motherboard.
- Remove old thermal grease from both heatsink and processor.
- Degrease the surface, wipe it dry.
- Spread the thermal paste in an even thin layer over the surface of the processor, does not go over the edges.
- Install and secure the processor back to the motherboard.
- Install and fix the cooler.
Disassembly features depend on the model of the installed parts. A clearer understanding of how to apply thermal paste to the computer processor will help you easily find videos with a detailed analysis that are suitable specifically for your type of cooler and processor.
The procedure for applying thermal paste itself does not change depending on the type of spare parts!
When it’s time to change the paste
A good thermal paste will perform its function for a long time, up to three to five years. On stationary computers, replacement is rarely carried out, but when cleaning a laptop, it changes every six months or a year. Due to the design features of modern laptops, the old, but still functional paste is removed during parsing and cleaning. Without this, it will not be possible to clean everything completely, while on a stationary computer for periodic household cleaning, it is not necessary to remove the radiator cover.
- When removing the cooler and radiator on a stationary computer;
- When cleaning the laptop (at least once a year);
- When the paste dries on the processor;
- With poor heat transfer and regular overheating.
If a computer or laptop often starts to overheat and turn off, it’s time to clean it and stock up on a heat-conducting compound.
You can first try cleaning a desktop computer without replacing it, but if the problem persists, you will have to disassemble it completely and clean it more thoroughly. You can understand which thermal paste is best for a computer by taking the heating level and cleaning frequency.
General recommendations for replacement
The main rules for how to change thermal paste on a computer:
- Applies in a thin and even layer. The thinner the better.
- Pre-remove the old composition.
- Be sure to clean and degrease the surface with alcohol before applying a new composition.
If you cannot calculate the quantity. apply in a thin layer, put on the radiator and then again with them. Is there a surplus on the radiator? Too much. Are there prints of the chip itself? Too few. After that, you will need to remove the thermal paste again and apply a sufficient amount.
The application of thermal paste is the final element of the computer cleaning process. Then it remains only to collect, check the performance of the computer or laptop and the afterbirth after the level of its heating. By the next cleaning.
How often and when to change the thermal paste on a laptop
For your laptop to last as long as possible, proper care is required. The processor may overheat during operation. This in turn leads to malfunctions and expensive repairs. In some cases, a new device is purchased, but this is very expensive. To prevent such situations, you should clean the dust and replace the thermal paste.
Do you often need to clean dust and change the thermal paste in a laptop? It depends on the:
- Frequency of computer operation;
- Thermal paste brands.
When a replacement is needed?
When it is necessary to change the thermal paste, they also carry out dust scrubbers in the device. These two processes are related. The notebook accumulates dust during operation. Desktop computers are less susceptible to this.
It is recommended to clean the laptop from dust once an hour. The first cleaning can be done superficially with a car vacuum cleaner. In the future, in order to clean and replace the thermal interface on the computer, you will need to disassemble it.
The devices can be used for games or office work. Therefore, their load will be different. In the first case, the paste is changed more often. It is recommended to make such a replacement in gaming laptops at least once a year. This also applies to computers running graphics and multimedia software. In office devices, you can replace the paste after two years of operation.
The processor brand also affects the frequency of thermal paste replacement. It will have to be changed earlier in AMD processors. Intel models run cooler as they generate less heat.
In addition to the indicated cases, it may be necessary to change the paste when the processor does not work correctly. Signs of this will be:
- Overheating of the processor. Normal temperature does not exceed 80 degrees.
- Spontaneous shutdown.
- Constant freeze.
The temperature of the processor and video card is measured using special software. Examples are:
How to replace yourself?
The computer can be handed over to the masters of the service center. Cleaning and changing the thermal paste is very inexpensive. To independently resolve the issue, you must disassemble the device. Care and accuracy will be required.
- Unscrew or remove the rear cover. Mounting can be carried out with screws or latches, depending on the model.
- Disconnect the cooler and cooling (copper tubes).
- Carry out dust cleaning. The cooler can be cleaned by hand, with a napkin or brush. With microcircuits, dust is removed by blowing using a car vacuum cleaner or a can of compressed air.
- Remove old paste carefully. This can be done with a cotton swab with alcohol. It is necessary to make sure that the liquid does NOT spread, but only covers the thermal interface. Then it takes time for the alcohol to disappear.
- The new paste is applied in small quantities. It should not go beyond the surface. The paste needs to be smeared, it will be distributed during the assembly process.
- The cooler, cooling, cover is being installed back.
Some users use special stands for additional cooling. They help keep the temperature of the processor normal, but do not obviate the need to remove dust and change thermal paste. These procedures are NOT guaranteed to be completely free of malfunctions, but will help extend the life of your laptop and delay repairs.
How to properly change thermal paste
So, before you spread the thermal paste, you need four things:
- Cotton wool for removing old and excess thermal paste. It should be soft, and not contain solids and impurities, in order to avoid scratches.
- Rubbing alcohol to remove old thermal grease, remove grease stains.
- Any object, which will be used for smearing thermal paste on the surface, acting as a kind of spatula. For example, a plastic card or something made of plastic and with a flat surface works well.
- And the thermal paste itself.
Before changing the thermal paste on your computer, get to your chip by removing the heatsink and cooler. And remove the old one that has served its term. To do this, use a clean cotton swab dipped in alcohol.
After that, apply a thin strip of thermal paste on one side of the chip, and then gently, with one light movement of the “spatula” (plastic card), spread it evenly over the surface of the chip.
To properly spread the thermal paste, it is necessary to provide its thinnest layer. It is also impossible to allow various “islands” of the surface NOT covered with thermal paste.
When smearing thermal paste, make sure that no excess remains outside the chip surface. All excess will need to be carefully removed with a cotton swab.
It is correct to smear thermal paste either on the surface of the chip or on the surface of the radiator, and not, as would-be masters do, on both sides. DO NOT make a double layer. As mentioned, the thermal paste should be as thin as possible.
How often to change thermal paste
How often the thermal paste needs to be changed depends on the operating conditions. The normal mode is to replace the thermal paste once every six months or a year. This is provided that the temperature of the chip does not constantly reach the critical point.
If the temperature is consistently high (which is undesirable), then the thermal paste will need to be changed often. once every couple of months. But it is better not to allow such critical marks and observe the temperature regime of the machine.
How to check if thermal paste is applied correctly
I smeared thermal paste, screwed the radiator back on, and turned on the computer, the question arises. did we do everything right, especially if we suddenly observe that the chip is still very hot.
In fact, in order to check if the thermal paste is applied correctly, you need to remove the heatsink and check out what stain the thermal paste left on its surface after pressing it against the processor chip.
If you see there empty areas without thermal paste, then an air bubble has formed, which spoils the cooling. If the contact spot occupies the entire area, then the thermal paste is applied correctly. In general, it is recommended to do this even before you turn on the computer.
How often to change thermal paste, and how to do it
Let’s talk about how often you need to change thermal paste. After all, an untimely replacement can be a prerequisite for “freezing”, overheating and even iron breakdown. And this cannot be allowed when it comes to an expensive processor. Anyway, a malfunction is very unpleasant. Since changing the thermal paste on the processor is very simple, I will tell you one easy way to do this.
Thermal paste is needed in order to ensure normal heat dissipation from the computer processor or any other chip in the system.
Accordingly, timely and correct application of thermal paste ensures the required temperature regime and normal operation.
How often do you need to change the thermal paste in a laptop
Sometimes you will notice that some part of the laptop keyboard has become hotter than others. Or, in general, the following unpleasant situation arose: you are forming an important document for work, and suddenly your computer turns off without warning.
The concept and purpose of thermal paste
The situations described above can be saved by an elementary replacement of the thermal paste on the processor. To do this you need to Unscrew the top cover of the laptop with a screwdriver.
Thermal paste itself is a substance that provides thermal conductivity. An alternative to it can be a thermal pad, but it is used only when there is too much space between the contacting parts.
Most often, you still need a paste. It always contains metal chips in order to ensure electrical conductivity. Therefore, it is not worth putting it on the electronic component in a too thick layer. the processor can be burned this way. In addition, during application, you must act very carefully and make sure that the thermal paste misses the surrounding parts, otherwise there is a risk of a short circuit when the computer is turned on.
In fact, despite all these points, replacing heat transfer paste is NOT that difficult. it will take you no more than 15 minutes.
How often is it necessary to change the thermal paste in a laptop
For comfortable work, it is generally recommended to arrange cleaning of a home laptop at least once a year (sometimes it is recommended even once every six months).
Office equipment can be cleaned every three to four years.
In order not to bring the situation to the states described at the beginning of the article, you can periodically view device information. For example, through the AIDA64 program. After you have downloaded, installed and launched it, we find information about the processor temperature. If it is higher than 75-80 degrees, then replacement is required immediately.
So how do you do all this? We offer a detailed algorithm of actions:
- Removing the battery.
- Using a screwdriver (usually a cross), remove the back cover of the laptop.
- Wipe off the accumulated dust with a dry cloth and gently remove the old dried thermal paste with a cotton swab soaked in alcohol.
- Squeeze some new paste out of the syringe into the center of the processor. Usually it is not necessary to smear it, but you can do it with some kind of plastic card.
- Installing back the cooling radiator.
- We screw the cover back.
By following these simple rules, overheating and failure of the laptop can be avoided.
Why change thermal grease on a processor
To answer this question, let’s start with why you need thermal paste at all. The fact is that any chips in the course of their work generate heat, and such large and efficient chips as the central processor of a desktop computer generate a lot of heat. In order for the processor NOT to overheat and NOT fail, a radiator is installed on it, which removes heat from the processor and dissipates it into the surrounding space.
The problem is that neither the heatsink nor the processor itself have perfectly flat surfaces. As a result, when a heatsink is installed on a processor, a microscopic layer of air forms between them, which significantly impairs the transfer of heat from the processor to the heatsink.
What does dried thermal paste look like on the processor and heatsink
Just to solve this problem, thermal paste is needed. It fills the joint space between the heatsink and the processor and improves heat transfer, because the thermal conductivity of thermal paste is much higher than the thermal conductivity of air.
But, thermal paste tends to dry out. When this happens, the thermal paste changes from a liquid and plastic state to a solid or powdery state. Naturally, in this state, the thermal conductivity of the thermal paste is significantly reduced, heat transfer to the heatsink deteriorates and the processor begins to overheat. In case of severe overheating, the so-called “processor throttling” will begin, the processor starts skipping clock cycles in order to lower the temperature, and if the temperature rises further, the computer will restart. Modern processors rarely fail due to overheating, usually restarting the computer saves the chip, but there are such cases.
In order not to prove the computer to such problems, the thermal grease on the processor needs to be changed, at least from time to time.
How often do you need to change the thermal paste on the processor
Many users have heard that the thermal paste on the processor needs to be changed, otherwise it will dry out and the processor will start to overheat. In general, this is true, but there are many myths hovering around the replacement of thermal paste. For example, you can often hear that thermal paste must be changed every six months or a year, otherwise overheating is simply inevitable. Here we will try to dispel such myths and tell you how often you need to change the thermal paste on the processor and why do it at all.
How often to change thermal paste
Now to the question of how often you need to change the thermal paste on the processor. In some articles on the Internet you can find recommendations with specific periods of time. Somewhere they write that the thermal paste needs to be changed every six months, somewhere that it cannot be changed for 3-5 years.
How fresh thermal paste is applied to the processor
It is not entirely correct to give such recommendations. After all, the drying rate of thermal paste is very dependent on factors such as:
- Thermal paste brand;
- The temperature at which she worked;
- CPU load level;
If this is a high-quality thermal paste that was used on an office computer, where there is no heavy load on the processor and high temperatures, then it can remain in a liquid state for 5 years or more. On the other hand, cheap thermal paste on a powerfully overclocked gaming computer can dry out in 1 hour.
Therefore, it is impossible to give an exact answer to the question of the frequency of replacement of thermal paste. But, you can understand for yourself whether it’s time for you to change the thermal paste or not. To do this, you need to monitor the temperature of the processor. If your CPU temperature rises above:
- 45 degrees idle;
- 65 degrees under load;
Then it’s time to take measures to reduce it, for example, remove the cooler, clean it from dust and replace the thermal paste with a new one. You can read more about how this is done in the article on replacing thermal paste. If the processor temperature does not yet exceed the specified values, then the thermal grease can not be changed, it is in a normal state. If you really want to, you can simply remove the dust from the cooler, and not remove it from the processor. For this it is very convenient to use a can of compressed air.
As for the choice of a new thermal paste, we recommend choosing brands such as:
- Arctic Cooling MX-4;
- Noctua NT-H1;
- Thermal Grizzly Kryonaut;
- GELID GC-Extreme;
information on choosing thermal paste can be obtained in this article.
Does the thermal paste brand matter?
There is a fierce battle among manufacturers of cooling systems for the attention of buyers. They offer products with a very high thermal conductivity (the higher it is, the better), others lure customers in large volumes. But in most cases all this is redundant for the average user. Premium solutions are needed for ultra-fast gaming processors or for extreme overclocking enthusiasts.
Numerous tests show that premium products do NOT do much better at CPU cooling than budget solutions. We also adhere to this point of view. If you need to greatly reduce the temperature, then the most effective solution would be to buy a powerful cooler with a lot of copper pipes. Or you can even switch to water cooling. In the best case, buying an expensive thermal paste will lead to a temperature drop of 5-10 ° C, which is not so much.
What is thermal paste for??
Thermal paste is a special compound that is placed between the cooled surface and the radiator. It is needed for more reliable and meaningful contact. The shelf life of thermal paste directly depends on the operating conditions. If the interface gets very hot and regularly passes a lot of heat, the paste will NOT last long in this mode. We’ll have to change it in six months or a year. And if the processor is not loaded as much (as, for example, in office PCs), you can return to the issue of replacement in a few years.
But this is just a theory. In practice, it turns out that it makes no sense to change the thermal composition according to strict regulations. If the temperature of the processor under continuous 100% load is within the permissible values, then everything is in order with the cooling. You can check the work of the “stone”. For example, using the free AIDA64 utility, I ran a stress test. If you DO NOT notice overheating, there is no cause for concern.
How often do you need to change the thermal paste on the processor?
Should I do this as a preventive measure or only for symptoms of overheating?
When assembling a computer, one of the most important steps is applying thermal paste to the processor heat spreader cover. Many novice users think this is a one-time operation that does NOT need to be repeated. In fact, in most cases, you will sooner or later have to return to this procedure in order to achieve the most efficient cooling. Computer hardware developers recommend updating the thermal interface once or twice a year. But is it really that necessary?
How to properly replace thermal paste?
In general, this is a very simple procedure that even a novice user can handle. Below we will provide a short guide. We described all the nuances in another article.
- Power off the computer.
- Disconnect all cables from the motherboard and remove it from the case.
- Dismantle the CPU cooler and open the socket with the small lever.
- Use acetone and a tissue to completely remove the old thermal grease.
- Dispense a small drop of fresh liquid onto the processor cover and distribute the interface evenly over the surface using a plastic card.
- Now you can collect everything in reverse order.
How to choose thermal paste
It is worth noting that the thermal paste should NOT be too liquid or too thick. Since in the first version it simply will not create the necessary contact, in the second it falls in lumps as Cooler Master thermal paste did when we tested it, perhaps it was just defective thermal paste, or old, but still. As our research has shown, mx-4 thermal paste has good performance, and many engineers use it.
How to remove thermal paste from a surface
Thermal paste is perfectly removed with a napkin for office equipment, pre-soaked in alcohol. It is possible without alcohol, if it is not a laptop, and the processor crystal will NOT be damaged by the second materials. DO NOT use acetone, solvents or water. Desirably lint-free, synthetic napkins. In the case of a laptop, you need to be very careful when disassembling, assembling the laptop, as well as cleaning the processor crystal. after all, its surface is NOT protected by metal, which means that it can be easily damaged. If the thermal paste was with aluminum shavings, then be especially careful. avoid contact with radio components.
How to properly apply thermal paste to the processor
The thermal paste must be applied evenly, without gaps. And don’t look at the fact that most processors with a metal surface that distributes heat, you should still follow this rule. The size of the thermal paste applied to the processor is slightly larger than a grain from an apple. Further, a special spatula must be distributed over all surfaces. It is not necessary to spread thermal paste on the radiator.
Why is thermal paste with the addition of aluminum shavings bad
It removes heat well and if the manufacturer is normal, then only one sin remains behind it. if there are radio components near the processor or surface elements that you smear that can be short-circuited, they are likely to short-circuit. If of course such thermal paste gets on them. over, as a rule, this does not happen immediately, but after a while, when the thermal paste dries.
How often should the thermal paste be changed
A good thermal paste can last 3 years or even more, but nevertheless, if the owner of a laptop, then when cleaning the laptop from dust, you will still have to change the thermal paste. In stationary computers, unlike laptops, the replacement period increases. Indeed, in such a computer it is not necessary to remove the radiator in order to clean all surfaces from dust. Although cleaning a desktop computer with a full parsing and changing thermal paste is considered better than partial.
What is thermal paste and why change it?
Thermal paste is a heat-conducting compound that improves heat transfer between the heating element (processor, video card) and the radiator, it can be of different consistencies, liquid (almost like water), medium density and thick. Also of different colors mainly white, gray and blue.
What thermal paste we do not recommend using
Very often, out of ignorance or lack of experience, white thermal paste is applied, as a rule, it is KPT-8, KPT-16 or the so-called “silicone”. We strongly DO NOT recommend using these thermal pastes as they have very low heat dissipation rates and dry quickly, which leads either to frequent replacement of such paste or to damage to your device from overheating.
Alternative to thermal paste
Thermal interface is an alternative to thermal paste, but it is its replacement. The thermal interface is used to remove heat, but its thermal conductivity is lower. There are also advantages. it is not so capricious, it can serve much longer and be reused if it is not deformed.
There is also a thermo-gum, it performs the same role as thermal paste, but it is very elastic and sometimes stretches, which is why it got this name.
