How To Apply Thermal Paste On Laptop

How to change thermal paste in a laptop: an immediate process

Before proceeding with practical actions, you need to prepare a simple tool: a thin Phillips and flat screwdrivers, an unnecessary bank card, an ordinary paint brush, alcohol and a small piece of cloth. Certainly, purchase thermal paste. Yes, and remember: don’t skimp on quality.

Reverse process. assembly

Replacing thermal paste in an Asus laptop is done in the same way. according to the above instructions. Nevertheless, this brand of laptops is incredibly demanding at the time of assembly. Therefore, before disassembling a portable device, and do not be lazy, sketched a schematic drawing of your laptop (the screws are placed on the graphically corresponding place displayed as you disassemble). This is necessary so that the reverse assembly process does NOT cause any difficulties, since often during installation the screws DO NOT correspond to the screw-in place. By the way, some manufacturers put markings on the fixation points that identify the type of fastener.

Step. Disconnecting internal device connectors

When it is necessary to replace the thermal paste in an Acer laptop, a complete disassembly of the laptop is required. Therefore, after dismantling the keyboard in the area that opens, Disconnect all contact loops and Unscrew the fixing screws.

Step: detaching the keyboard

At this stage, you should be more than careful, since the button module is connected to the laptop motherboard using a ribbon cable. The risk of damaging this connector is incredibly high if not careful.

Typically, the Keyboard Unit is secured with latches located around the perimeter of the module. However, the location of the retainers in each modification is individual. Gently “sinking” the screwdriver in the area of ​​the upper edge of the keyboard, at the same time prying it until it comes out.

Step. Cleaning and lubricating the fan

Use a brush to free the part from dust deposits. A drop of engine oil into the inside of the rotating element will soften the fan blades and save you from extraneous noise later on.

Step. Dismantling the casing segments

To get to the laptop cooling system, it is often required to disassemble almost the entire device, as they say, to the last screw. However, replacing thermal paste in a Lenovo laptop can be done in a completely different scenario. It is enough to unscrew only one protective cover, and access to the radiator is open. It is worth noting that most modifications of laptop computers hide the cooling system deep enough in their body depths, so a universal plan of action will look like this:

  • The back of the laptop has several compartments, which are closed with plastic or metal covers.
  • Unscrew the screws carefully, as there is a risk of stripping the thread.
  • In some cases, the optical drive can be easily removed with just one screw. By the way, replacement of thermal paste in MSI laptop is done without removing the DVD / CD recorder.
  • Ultimately, you need to remove all the attachments of the system: RAM, hard drive, wireless modules.
  • The final step is to unscrew all screws. Be careful, as a missing bolt can fix the removable laptop component, which will be discussed in the next paragraph.

Step. Correct layer and installation of the radiator in place

Don’t think that the more “binder” you put on the parts, the better. This is a delusion, moreover, dangerous (in the sense of implementation)! Give a little thermal paste to the plane of the cleaned part and use a credit card to stretch it with a thin layer over the entire surface.

Fix the segments of the cooling system to the motherboard according to the marked script. DO NOT disregard this recommendation, as when skewing (fixing two bolts on one side, and then on the other), there is a high risk of damaging the silicon surface of the processor. And the paste will lie unevenly. In total. imminent overheating.

Step. Dismantling the cooler and radiator from oregano

Replacing thermal paste in an HP notebook is only possible if the cooling block is completely removed from the system board. However, this condition is relevant for the vast majority of laptop modifications.

  • To remove the heatsink and heatsinks from the system board, you usually need to remove four screws in the CPU area and two. In the area of ​​the graphics chip. Depending on the manufacturer and model of the laptop, the fixing scheme may be completely different.
  • At the same time, there is a certain mandatory algorithm for screwing and tightening the bolts, with the help of which the cooling system is fixed. The manufacturer marks the removable part with numbers, which indicate the sequence and order of unscrewing.

The art of foreseeing, or When you need to replace thermal paste in a laptop?

Yes, just in time a deviation from the norm is noticed (meaning the general moment of using a laptop) and steps are immediately taken to resolve the problem situation will help you avoid all sorts of computer troubles. In order to understand that a laptop needs prevention, you do not have to be a specialist. However, the main symptoms of a malfunction should be known, so to speak, “in person”.

Which thermal paste to choose?

Firstly, I would not recommend KPT-8 thermal paste, which you can find almost anywhere where thermal paste is sold. This product has some advantages, for example, it almost does not “is shrinking “, but still today the market can offer slightly more advanced options than those that were produced 40 years ago (yes, this is how much KPT-8 thermal paste is produced).

On the packaging of many thermal pastes, you can see that they contain microparticles of silver, ceramic or carbon. This is not a purely marketing ploy. With proper application and subsequent installation of the radiator, these particles can significantly improve the thermal conductivity of the system. The physical meaning of their use lies in the fact that between the surface of the heatsink sole and the processor there is a particle of, say, silver and there is no paste compound. there is a large number of such metal joints on the entire surface area and this contributes to better heat transfer.

From those present on the market today, I would recommend Arctic MX-4 (and other Arctic thermal pastes).

How to apply thermal paste to the processor

If you are assembling a computer and you need to install a cooling system on the processor, or when cleaning the computer, when the cooler is removed, you need to apply thermal paste. Despite the fact that applying thermal paste is a fairly simple process, mistakes are common. And these errors lead to insufficient cooling efficiency and sometimes to more serious consequences.

This manual will guide you on how to apply the thermal paste correctly and will also show you the most common application errors. I will not go into how to remove the cooling system and how to reinstall it. I hope you know this, and even if not, it usually does NOT cause difficulties (however, if you have any doubts, and, for example, remove the rear You don’t always get the battery cover from your phone. you better don’t touch it).

Cleaning the heatsink and processor from old thermal paste

If you removed the cooling system from the processor, then be sure to remove the remnants of the old thermal paste from everywhere where you find it. from the processor itself and from the heatsink sole. To do this, use a cotton cloth or cotton swabs.

Remains of thermal paste on the radiator

It’s great if you can get some isopropyl alcohol and wet a wipe with it, then cleaning will be much more effective. I would like to note here that the surfaces of both the heatsink and the processor are NOT smooth, but have a microrelief to increase the contact area. Thus, the most careful removal of the old thermal paste so that it does NOT remain in the microscopic furrow can be important.

Place a drop of thermal paste in the center of the processor surface

Correct and Incorrect Amount of Thermal Paste

It is the processor, not the radiator. it is not necessary to apply thermal paste to it at all. There is a simple explanation why: the area of ​​the heatsink sole is usually larger than the surface area of ​​the processor, respectively, we do not need protruding parts of the heatsink with applied thermal paste, but they can interfere (including the contacts on the motherboard are closed if there is a lot of thermal paste).

Improper application results

Use a plastic card to spread the thermal paste in a very thin layer over the entire processor area

You can use the brush that comes with some thermal grease, just rubber gloves, or something else. The easiest way, in my opinion, is to take an unnecessary plastic card. The paste should be spread evenly and in a very thin layer.

In general, this is where the process of applying thermal paste ends. It remains to carefully (and preferably the first time) install the cooling system in place and connect the cooler to power.

Immediately after turning on the computer, it is best to go into the BIOS and look at the processor temperature. In idle mode, it should be around 40 degrees Celsius.

Some helpful tips

As you can see, replacing thermal paste in a laptop is, in general, not a complicated maintenance process at all, nevertheless it is incredibly responsible and requires a lot of attention from the user.

How much easier it would be if the owners of portable computing equipment followed a few simple rules:

  • DO NOT use your laptop in a damp room.
  • Cold environments or hot weather can also be detrimental to a laptop, especially with prolonged exposure.
  • During the operation of the compact device, make sure that the air intake openings are NOT covered by foreign objects.
  • Perform preventive maintenance on your laptop in a timely manner.

Depending on the intensity of use of the laptop, the thermal paste may have to be replaced after a year. However, now you know exactly when to resort to such a radical service method. All the best!

Comfortable in all respects, a portable device. a laptop. still has a number of disadvantages. A kind of Achilles’ heel of compact computers is considered to be a cooling system that is far from perfect, the efficiency of which over time is limited by another unfavorable factor. the impact of the external environment. In particular, the grids and filters of the laptop air intakes are inevitably clogged with dust particles, which, in turn, negatively affects the favorable heat removal. Replacing thermal paste in a laptop is inevitable, due only to the time frame and quality of the substance used. However, let’s take a closer look at such an important and responsible service process, as well as understand the main operational issues.

Step. Disconnecting internal device connectors

When it is necessary to replace the thermal paste in an Acer laptop, a complete disassembly of the laptop is required. Therefore, after dismantling the keyboard in the area that opens, Disconnect all contact loops and Unscrew the fixing screws.

Step. Cleaning and lubricating the fan

DO NOT disregard this recommendation, as when skewing (fixing two bolts on one side, and then on the other), there is a high risk of damaging the silicon surface of the processor. And the paste will lie unevenly. In total. imminent overheating.

Step. Separating the main body parts

When all the bolts are unscrewed, you need to carefully (prying with a credit card) to separate the upper part of the plastic frame from the lower one. Next, you need to dismantle the motherboard to perform the following steps.

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.

Alarm list

So, to your attention the price list of unpleasant surprises, which most users encounter so often and which are rarely corrected. It is likely that you have already encountered something similar in practice. Nevertheless, for a beginner, this is invaluable information, familiarization with which may lead him to the question of how to replace thermal paste in a laptop.

  • The accumulation of dust in the ventilation holes of the device prevents the passage of air in both directions.
  • Obvious cooling fan noise, as well as an incessant cycle of high rotation in any operating mode of the laptop.
  • Some body parts of the device get very hot even with short-term use.
  • Spontaneous shutdown.

Of course, this list can be substantially supplemented. However, the last of the danger signals requires immediate participation on your part.

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 to properly remove old thermal paste?

Regardless of the reason why you decide to change the paste on the processor, the first thing to do is turn off your computer and unplug the power cable. If there is a switch on the PSU, Set it to the “off” position.

After disconnecting the cable, you can press the power button on the system unit several times, just in case. This manipulation will remove residual electricity from the capacitors.

After making sure that the computer is completely de-energized, disconnect the cooler power cord from the mother and remove the cooling.

Then remove the processor from the motherboard by lifting the locking “lever”. Now we go directly to the removal of the old paste. Some masters recommend using a ruler or a plastic card to scrape off the paste, I prefer the more gentle option and wipe it off with a paper towel.

Dampen the cloth with alcohol and wipe the surfaces clean several times. You can also use cotton swabs or pads, and a bandage. But be careful not to leave fibers on the motherboard components.

If you don’t have alcohol, use cologne, acetone, or as a last resort WD40. Be careful with solvents to avoid getting them on the motherboard or other parts of your computer. After washing both surfaces clean with an alcohol-based napkin, insert the CPU into the socket on the motherboard, and proceed to applying the paste.

I almost forgot, the radiator and cooler will NOT be superfluous to clean from dust. this will save you from accidental ingestion of debris on fresh paste and provide better heat dissipation.

How to properly remove and apply thermal paste to the processor and graphics card?

Let’s discuss such an important aspect of PC or laptop maintenance as replacing thermal paste on the CPU and GPU. This information will be useful if you are going to change the CPU, heatsink, or simply notice that the computer is getting hotter. Also consider the differences between replacement on laptops.

How to properly apply thermal paste to your processor?

Moving on to the next, most controversial point. the correct application of thermal paste? I propose to consider three common ways:

  • Squeeze a drop of paste onto the processor and simply press down with a heatsink. In theory, it will be evenly distributed over the surface of the CPU under the pressure of the heatsink. In practice, you need to guess with the amount of paste to be squeezed out. It should be a thin transparent layer from which you can even distinguish the inscriptions on your stone. The radiator must be fastened by pressing it with equal force in all directions without skewing. If it rises even a little crookedly, then the paste can be squeezed out all to one side and the processor floor will remain without a thermal conductor.
  • Some thermal paste manufacturers ship a small plastic spatula with the tube. Apply one or more drops to the processor and spread gently. The advantage of this method is that you can visually control the thickness and uniformity of the coating. If you did not have such a spatula in the kit, you can use any plastic card, an old ruler, or even a finger wearing a rubber glove. The main thing is to try to make the layer as thin and even as possible. DO NOT use hard objects that may scratch the processor.

After applying thermal grease to the processor, carefully reinstall the cooler. It is very important to do this, and not fidget with the radiator until it is already firmly in place. Now you can and should move it slightly so that the paste fills in the irregularities, and click the mount. DO NOT be alarmed if the first days the processor temperature differs from the expected one, the manufacturers themselves give up to seven days of running-in, just wait a little.
