How to test a laptop cooler for performance

Cooler working poorly? The reason is not always in him

A 100% fan failure is indicated by the following:

  • Visible mechanical failure of the impeller (the moving part of the cooler with blades, which is shown in the picture below).
  • Stiff impeller travel, which is felt when trying to turn it by hand.
  • Fatal mechanical obstacle to the rotation of the impeller.
  • Stopping the rotation of the fan when moving its cable (bending or loosening of the contacts).

In these situations, replacing the fan will be the easiest and most correct solution. Although, if the reason is only in the cable, most often you can do with simple repairs.

The fact that the fan is not to blame for the problem, but something else, is indicated by the following symptoms:

  • The cooler rotates at high speed, but cold air is blown out of the ventilation grill. The reason may be improper installation or breakdown of metal parts of the cooling system.
  • The cooler, judging by the noise, rotates quickly, but the air does not come out. The reason is the blockage of the ventilation holes on the body of the device with compressed dust.
  • The cooler spins at a constant high speed, which does not drop when the load on the processor and other cooled devices decreases. The reason is incorrect management.
  • When the laptop is turned off, the turntable makes a jerk or 1-2 turns and stops. After that, the laptop turns off immediately. The reason is a short circuit in the device’s devices, a malfunction in the power circuits.

Obviously, in these situations, replacing the cooler will not help, since the source of the malfunction is not in it.

And in the following cases, the reason may lie both in the cooler itself and in its control system or environment:

  • When you turn on the laptop, a message about problems in the cooling system is displayed on the screen: “SystemFan”, “System FanFailure”, etc. The culprit is often a worn out fan, but sometimes this is caused by a malfunction in its control or a physical obstacle to rotation (mechanical stopper, magnetic field nearby speaker, etc.).

  • The cooler does not rotate, although when pushed by hand, the impeller easily moves.
  • The cooler rotates too slowly, its speed does not correspond to the intensity of the load on the system. Computer shuts down due to overheating.
  • The impeller moves in jerks with periodic stops. Computer shuts down due to overheating or slows down.

Let it be quiet! How and what to replace a faulty cooler on a laptop

The cooler of a mobile computer sometimes becomes too noisy over time or stops cooling the system normally. Cleaning and lubrication, unfortunately, do not save for long. Only installing a new turntable instead of a worn one helps to radically solve the problem, but the question is, how to do it correctly? A little patience, gentlemen! You will find out soon enough. Today we’ll talk about how to replace a cooler on a laptop, by what parameters to choose it, in which cases the replacement will give the desired effect, and in which it will not, as well as how to make one cooler out of two with your own hands.

How to identify the culprit

How to dismantle and then install the cooling system in the laptop case is described in detail in the article about replacing the processor. By the way, in addition to the cooler itself and the screwdriver, you will need good thermal paste.

The easiest way to diagnose a fan malfunction is when there are two (or more) of them in a laptop. If the problem is observed on one side, most often it is enough to check this cooler by replacing it, connecting the second one instead. If on both sides, then it is obvious that a failure has occurred in the control system, since all the fans fail at the same time extremely rarely.

Unfortunately, most mobile computers are equipped with a single turntable. In such cases, the diagnostic algorithm will be as follows:

  • Remove the cooler from the seat in the laptop case, disconnect it from the motherboard and clean it from dust. The fan casing can be half-open or closed on all sides. The latter are collapsible and non-collapsible (glued or riveted). Parts of collapsible housings hold latches or screws together.
  • If the housing is semi-open or collapsible, check the integrity of the mechanical parts of the impeller. Check her mobility. Normally, it should rotate without effort, even from a weak push. Further we will only talk about collapsible fans, since attempts to open non-collapsible ones often lead to their breakdowns and unsuitability for further use. The performance of such devices can only be tested by replacing.
  • If the impeller is removable (to check this, gently pull it up, being careful not to damage it as the blades break easily), remove it from its socket and make sure nothing gets inside. Remains of thickened grease (by the way, it is she who can block the cooler) remove with a napkin, additionally clean the impeller shaft with alcohol.
  • Put a drop of silicone or lubricating machine oil on the impeller shaft (grease, lithol, petroleum jelly and other viscous compounds are not suitable for this). If the fan is non-separable or you do not find any debris inside, skip this step. By the way, after lubrication, the noisy fan can work normally for some time, but, unfortunately, not for long.

Place the fan on the seat in the laptop case and, without screwing it in, connect it to the connector on the motherboard. Switch on the device. Observe the behavior of the turntable. Normally, at the moment of power supply, it can jerk and stop, so that after a few seconds it starts rotating at normal speed. If you see a different picture, raise it above the seat, move the wires to exclude damage to the latter and the impact of the environment.

How to choose a replacement cooler

The laptop fan always blows out!

Fortunately, most mobile computer manufacturers have fans that fit more than one model of their brand. Therefore, difficulties in finding the right part on sale rarely arise, unless, of course, the laptop is too old.

Putting together one cooler out of two. Salvation if there is no suitable one on sale

  • The height of the impeller of the donor cooler should not be higher than that of the recipient. Better when she’s a little lower.
  • The slope of the impeller blades of both fans must be directed to the same direction (both right or both left).
  • Both parts must be collapsible.
  • Ideally, the order of pinout of the connectors (determined by the color of the wires) and the number of contacts should match.

Fans of modern laptops have 4 contacts on the block (5 V power supply, tachometer output, control input of the shim controller and ground), but sometimes there are turntables with three-pin (power, tachometer output, ground) and two-pin (power, ground) connectors. The last two varieties are used on the oldest or most budget laptops and netbooks and are not suitable for replacing 4-pin ones. Although with reservations, for the cooler to start spinning, you just need to power it up, and adjusting the speed is not the most important thing (it will constantly spin at maximum). Of course, if your task is to provide the computer with cooling during the search for a normal spare part, and not constantly.

Unfortunately, the 4-pin connectors of mobile coolers have not been brought to a single standard, and the wires on them are arranged in a way that was more convenient for the manufacturer. Therefore, if you are not able to pick up a replacement with the same wiring order as on the old turntable, you will have to remove them from the block and insert them into it in the right order. By the way, the same will have to be done if the block of the new cooler is not identical to the block of the old one.

The ends of the wires in the plastic connectors are held in place by tiny latches. To remove the wires, the latch must be lifted with a small flat tool, such as a screwdriver. When you insert the wiring back into the socket, it locks automatically.

The impeller of the donor cooler can be rearranged into another case only together with the motor, but the motor is firmly attached to one of its halves. To separate it from the body, you need to saw the joints along the yellow lines shown in the picture below. In the same way, we prepare the body of the native fan, that is, we remove the faulty engine from it (the cut is made along the red lines). Areas marked with white circles must overlap. they will become junctions.

At the penultimate stage, we insert the donor fan motor into the prepared recipient case and connect them by soldering or gluing with superglue (if both parts are metal, it is better to solder them).

That’s all, “Frankenstein” is ready, now you can assemble and install it in your laptop. If everything is done correctly, the fan will cool the system like a native one and will last quite a long time.

Changing BIOS configuration

BIOS settings contain many parameters and set the interaction between the hardware parts of the computer, directly affecting its performance.

    To open the BIOS interface, restart the laptop and press the F2 key, sometimes F9 or Del can be used in the device for a similar purpose.

The menu depends on the brand and manufacturer of the motherboard. Go to the “Advanced” tab and click on “Hardware Monitor” or “Temperature”.

Next, open the “Save Exit” tab, select the “Save Changes and Reboot” item, confirm the decision with the “Yes” option. After reboot, the fan will run faster or slower according to the new settings.


The SpeedFan utility collects data on the operation of the fans and provides the ability to configure parameters such as the rotation speed of the propellers, the percentage of CPU utilization allocated to some system processes, the bus frequency, set up a proxy server to access the Internet, etc.

    Open up SpeedFan. The application detects system controlled fans and lists them in the lower half of the window. Shown next to the speed as a percentage of the maximum value and arrows for adjustment.

  • The screenshot shows that Speedfan only detected one configurable cooler on the GPU. It should be borne in mind that this function of the program will not work with old motherboards, as well as if the fan contacts are incorrectly connected.
  • SpeedFan is a multipurpose application that is great for monitoring the temperature of chips and hard drives. These parameters can be controlled through a convenient user interface, without the need to open the BIOS or open the computer case.

    Diagnostics of a cooler on a laptop

    Breakdowns and failures in the cooling system of laptop computers quickly affect the overall performance of the system and, in addition, significantly increase the risk of defects associated with thermal damage to processors, memory, hard drives and temperature-sensitive areas of the board. Therefore, when a laptop starts to “slow down” when working with familiar applications, experienced users immediately try to assess the degree of overheating and check the operation of the fans.

    Laptop cooler testing

    Due to the compact arrangement of parts inside the laptop, opening the case and disassembling becomes much more difficult than for a stationary PC system unit. An inexperienced user runs the risk of damaging the fasteners and contacts, so it is better to start testing with a software check.

    Physical check

    For hardware testing, you will need to partially disassemble the laptop. Inattention and lack of necessary skills can lead to damage to parts, so we do not recommend ordinary users to do this on their own. It is better to take the laptop to a service center, which will help save your nerves and not lose the warranty.

    READ  Laptop Hard Drive How To Choose

      Before starting work, we carefully study the instructions for disassembly.

    Unscrew the bolts and remove the cover. To check, dismantling the cooler is not necessary, it is much more important to get free access to the wire that supplies power. Usually this is a 4-Pin or 3-Pin cable, but there is also a variant with two contacts.

  • You will also need a USB cable. Cut off the connector from one end. Then we remove the insulation from the red and black contacts.
  • The operating voltage for the fans is 5-12 V. We get the desired value by connecting the USB to a second computer or a smartphone charger.
  • We disconnect the cooler cable from the motherboard and connect the contacts of the same color, red with red, black with black. If the fan does not start spinning, then it needs to be replaced.
  • To increase the efficiency of cooling, the inside of the laptop is cleaned of dust, the layer of thermal paste between the cooler and the radiator is renewed.
  • If your laptop still feels too hot for you, consider purchasing a cooling pad or a more powerful cooler. Preventive measures to prevent overheating of your laptop keep it running and extend its useful life.

    How to test a laptop cooler for performance

    If your mobile PC starts to “slow down” or turn off, first of all, you need to check the health of the cooler.

    Cooler software testing

    The essence of checking with the help of software is to track temperature fluctuations on the elements of the laptop. Let’s look at how to check using the Speed ​​Fan utility as an example.

    This third party software can be downloaded from the Internet for free. After installation, during the first launch, it will determine the cooler itself and give all its indicators. You can also see the temperature on the details of the laptop at the current moment.

    If you see that, for example, the processor is too hot (there will be a fire image next to the CPU line), increase the rotational speed of the cooler fan by changing the values ​​in the corresponding window at the bottom of the screen. In this case, the temperature should drop to normal parameters. If even an increase in speed to 100% did not help, the cause of overheating is not related to the operation of the cooler.

    In order for the indicators to be as accurate as possible, run a capacitive program, such as a game, on a portable device. This is necessary in order to load the laptop to the maximum. Then the picture of the state of the elements and the operation of the fan will be more accurate.

    If SpeedFan does not suit you for some reason, use other similar programs:

    • AMD OverDrive. a utility designed for a machine with an AMD processor;
    • Riva Tunes. for Intel processors;
    • From the manufacturer Asus. Asus Eeectl.

    How to check a cooler on a laptop: all the ways

    One of the factors affecting the normal functioning of laptop components is the correct operation of the cooling system. If the cooler fails, parts will start to overheat and fail.

    Hardware check

    You can check how the cooler works by connecting it to another device. To do this, you will have to disassemble the laptop.

    First, turn it off and disconnect all wires, remove the battery. Get rid of static electricity. wear a special bracelet, gloves, or just touch the metal.

    Option 1. Your model is opened by removing the back cover. Unscrew all the bolts (check under the stickers and rubber caps, feet). Next, pry it around the perimeter with a plastic plate (bank card) and remove.

    It is possible that your gadget has a “window” specifically for a cooler. That is, you do not need to remove the entire cover.

    Option 2. To open the laptop, you need to remove the keyboard. Sometimes it is secured with latches behind the screen. Sometimes, in order to remove it, you need, as in the first option, to unscrew the bolts at the back, then turn the device over and pry the keyboard with plastic. In some models, some of the bolts securing the keyboard are hidden under the mouse panel. In this case, you need to remove her.

    Next, the motherboard is removed. It is not necessary to remove the cooler itself, but you need to free and disconnect the power connector. Although, if it does not interfere, you can leave it alone.

    In order to connect our cooler to another laptop, you need a special cable: on one side it has a USB plug, on the other two wires: and Such wires are connected to wires of the same color marking of the cooler, and the other side is inserted into the USB connector of another laptop.

    If the fan starts spinning without problems, it is working normally, and the cause of the problems with the laptop should be looked for elsewhere.

    Considering that you have already opened the gadget, clean it, including the cooler and all internal parts, from dust. it is a poor conductor of heat and can interfere with cooling.

    If you do not want to remove the fan, blow everything out with a vacuum cleaner or a can of compressed air, and large clouds of dust can be removed with a brush. Wipe all parts of the laptop with a soft cloth or cotton swab moistened with alcohol. It would also be nice to lubricate it. To do this, remove the sticker in the center and drip a couple of drops of machine oil into the hole or spray with WD-40. All these manipulations will help improve the cooler’s performance. Ideally, replace the thermal paste that glues the cooler radiator to the PC, but for this, the cooling device still has to be unscrewed and removed.

    External indicators (noise, heat generation from the computer, freezing)

    It is possible to understand whether problems have arisen against the background of a cooler failure by several signs:

    • the laptop began to make a lot of noise;
    • very warm air is emitted from the hole in the cooling system;
    • the bottom of the laptop gets very hot;
    • programs started to freeze;
    • the device periodically turns itself off.

    If at least one of the above signs appears periodically, you have a problem with the cooler.

    There are several options for how to check a cooler on a laptop.

    Optimum cooler speed

    To understand if the cooler is working properly, you need to start from the normal fan speed. However, this indicator does not have a single correct value. This largely depends on the device itself. You can find out the optimal parameters of the cooler from the manufacturer. Nevertheless, if we talk about the average normal speed, it is from 1500 to 2000 rpm with a quiet laptop. If you load it, the speed increases and can reach 4000 rpm. But, if you initially have a low-power cooler, such a speed may be too high for it. And vice versa.

    If you have determined that your laptop has begun to malfunction due to poor cooler performance, do not rush to buy a new one. Most often, problems arise due to its incorrect setting or contamination. Test it, adjust the fan speed, clean the system and, for sure, your laptop will work like new.

    How to check a cooler on a laptop

    Correct operation of the cooling system prolongs the life of the computer for a long time. In the presence of malfunctions, the parts begin to overheat and fail. If the equipment started to “slow down” or began to get very hot, then first of all, you should check the cooler on the laptop for operability.

    Using software

    You can skip the BIOS menu and solve a potential problem in the usual way. To do this, you only need the Internet and the name of the desired program.

    SpeedFan is a great app to help you determine if your cooler is working. Download it from the official source and install it on your PC.

    As soon as you start the program, you will see what the temperature is on the sensors. It will also be possible to manually change the cooler speed setting. To do this, uncheck the box next to “Fan autotune” and write the required rotation speed, calculated as a percentage.

    If the fixed number of revolutions is not suitable due to severe overheating, you can change the data in the “Configuration” section. The utility will automatically adjust to the selected value.

    Another useful application is AIDA64. It is preferable to use it for those who are fond of heavy games, especially online.

    If the temperature does not exceed 50 degrees, then the cooler is working properly. Exceeding this border indicates existing problems.

    Program check

    The easiest way to find out the cause of the problems and eliminate their consequences is to use the programs.

    On many devices, the BIOS affects the activity of the cooler. This is especially true for expensive laptops, although there are exceptions.

    IMPORTANT! If you have Acer or MSI laptops, then you should take a closer look at this method.

    Turn off the device and turn it on again. Once the boot screen appears, enter the BIOS menu. This can be done using the Del, F2 or ESC keys. The combination depends on the model of the purchased device.

    Going to the main menu, select the Power tab, which is responsible for the temperature of the processor and cooler. Now you need to find CPU Q-Fan Control and CPU Fan Profile. It is important that the first indicator is active. The second parameter is responsible for the fan speed:

    • Silent. the minimum amount of charge is consumed;
    • Optimal. the cooler will start to turn on at the moment of increased load on the laptop (this often happens when starting online games);
    • Turbo. continuous operation of the cooling system.

    For Lenovo owners, this advice may not be relevant.

    Cooler hardware check

    You can use a more difficult method. hardware check. To do this, you will have to disassemble the laptop and manually diagnose the cooler.

    Be sure to read the instructions before removing the fan. If the warranty period has not yet expired, it is highly not recommended to disassemble the laptop yourself. The best solution in this situation is to turn to professionals.

    If you do not want to visit the service center, you can make an independent diagnostic attempt. It is important to know that there is no need to completely remove the cooler. You only need wires to test on another device.

    To do this, you need a USB, which has a plug on one side, and black and red wires on the other. Adhere to the following algorithm of actions:

    IMPORTANT! If the fan starts spinning, then everything is in order with it. Perhaps you just need to clean the cooling system or replace the thermal grease.

    To get rid of contamination, it is not necessary to resort to removing the cooler from the laptop case. It is enough to blow it with a can of compressed air (in extreme cases, a vacuum cleaner will also do). If there is too much dust, you can use a brush to remove it.

    Then wipe the laptop with tissues or a cotton swab dipped in alcohol. This will increase the performance of the device even if there is no hardware problem.

    If the above methods did not work when you independently check the cooler for performance, take your laptop to a service center. Professionals will certainly cope with the problem that has arisen.!

    Used laptop

    Deciding to buy a used laptop? In this article, we will consider recommendations for checking a laptop before buying, what you should pay attention to before buying a laptop from your hands, as well as important points that can significantly reduce the purchase cost.

    Top Tips When Buying a Used Laptop You Want To Use For Office Work Or For Your Kids’ Fun.

    Used laptop / closed appearance

    When buying a used laptop, pay attention to its appearance. Scratches on the outer casing of a laptop are not always indicative of careless use. If the owner brought a laptop to you with a bag. this is a good sign, perhaps scratches appeared when the charger rubbed against the laptop case.

    It’s not worth making negative conclusions about a laptop if there are scratches on the case.

    Check the corners of the laptop for cracks or chips. The presence of such may mean that the laptop has been dropped. Such laptops should be avoided as they can damage the inside of the laptop and the hard drive if dropped.

    Next, take a look at the ports and connectors. Cracks or a broken connector indicate negligent use of the laptop. The charger connector breaks very rarely, and if there is such a crack, it means that the laptop was dropped with the charger connected, the same situation with the USB connector. Such a laptop is not worth buying.

    Used laptop / open state

    Inspection also begins with a check for visible defects. We check the keystrokes, sticky keys may mean that liquid has got into the keyboard, check the pressing of the touchpad buttons. And pay special attention to the screen. Check for rubber caps on the laptop screen, the absence of them may mean that the laptop screen has been changed. Find out the reason for the screen change.

    Used laptop / turning on laptop

    Press the power button. Pay attention to the presence of errors when starting the operating system. The presence of errors at best can mean that the operating system needs to be reinstalled, and at worst, replacing the hard drive is inevitable.

    Used laptop / laptop testing

    The laptop passed the previous tests, which means the operating system is booted. Connect the charger to your laptop.

    Checking the laptop battery. When the charger is connected, a charging icon should appear in the lower right corner. If a message appears stating that the battery needs to be replaced, reduce the purchase price. Replacing the battery will cost an average of 1,500 rubles.

    Disconnect the charger. What’s happening? If the laptop turns off when there is a charge of 20%, then the battery should be replaced. Check if the charge indicator matches the power cut.

    Connect the charger to your laptop. Try to move the connector a little, if charging has stopped, then the charger may need to be replaced, and in the worst case, the charger connector itself needs to be replaced.

    Keyboard and touchpad. It’s time to test the keyboard and touchpad. Using the touchpad, press the start button on the desktop. Thus, checking the functionality of the touchpad. Open a text program to test the keyboard’s functionality. Try to check the pressing of each button, check the functionality of the buttons “Shift”, “Enter”, “Del”. “Tab” and “Space”. While in the text editor, also check the pressing of the touchpad buttons, as well as the movement of the cursor.

    Screen. We check for dead pixels on the laptop screen, they are clearly visible against a dark background. On the contrary, screen scratches are clearly visible on a light background.

    USB Port. It won’t be superfluous to check every USB port on your laptop. Take a flash drive and check the performance of all ports one by one, as well as check the display of the drive on the “My Computer” tab. If the laptop turns off when a USB flash drive is connected to the USB port, it means that there is a short circuit on the USB port. This is a reason to lower the purchase price or refuse it altogether. Check if there is a Card Reader

    Wi-Fi. Make sure the laptop can see a wireless network that it can connect to. After connecting, enter the address of a web page, for example to make sure the page is loading.

    If you connected from a wireless network, but failed to load the web page, then the laptop needs to be configured and there is no doubt about the performance of the WI-FI card.

    Sound. Check the performance of the speakers by opening, for example, any music file. Listen to the sound of the speakers, the sound should be clear, even.

    Listen to the laptop cooling fan, if the fan is noisy during operation, then most likely the laptop cooling system needs to be cleaned from dust.

    CD / DVD drive. Test the CD / DVD drive with a CD or DVD. If the drive turns out to be inoperative, you will have to buy an external drive or look for a new drive for your laptop.

    Summary. Follow all the tips above when buying a used laptop and you will be sure to pay a decent price when buying a laptop.

    How to check if a server fan is working?

    how can you check if a server fan is working?

    The situation is as follows. On the server at night, 2 lower hot-swap fans stopped spinning at the same time, the server is running on the two remaining ones, turning on increased speed on them. Mat.board Itel SE7520AF2. There are no other servers to test these fans. I still consider it inexpedient to buy new ones, because there are doubts that the matter is not in the fans, but in the motherboard. The search has not yielded anything yet. Question: is it possible to check the performance (whether they are spinning) of these fans directly, without connecting to the mat. board? Connector 8-pi. The pinout is as follows: 1. Gd2. Pesece3. 12V4. Tach5. Gd6. Led powe7. Empty8. EmptyIn electrical engineering, I understand a little, so please state the testing methodology on your fingers or give links.
    Replacing the fans from the bottom to the top is technically impossible. different sizes. Swapping them in places gives nothing.

    Cooler: how you can check the performance of a server fan?

    On my old PC in 2003, just an old 320 volt power supply with average data for that time burned out or the short circuit has passed, I just remember there was a strong cotton and the light, as if from the short circuit, saw that there are blackening inside and a couple of burnt spots on the power supply board. I replaced the power supply unit with a similar one, but there was no fan in it, I took the fan from the burnt out power supply unit. I connected everything, I set it up, but the fan doesn’t want to connect the yellow and black wires.

    What kind of cooler are you asking??
    If the core, just check for the torque, you can observe the temperature of the core through the BIOS.
    Carefully remove the fan, if it’s a pity to tear off the cooler, but clean it, peel off the round sticker and drops of liquid oil (you can also use sunflower oil, but it’s better to use some technical oil), let the valve rotate to idle, put it in place and forget. | |

    I have a PC for a year and a half without cleaning.

    First, the vacuum cleaner is in your hands. Put on the tip (tapering towards the end) and vacuum.
    Secondly, check at least two coolers. on the process and in the power supply. First, just clean out the dust (by unscrewing the process from the radiator and unscrewing the power supply), then check how it rotates. If free. better not grease. If he (they) are already creaking. you can lubricate. In a couple of months, all one will creak and you will buy a new one. I used oil for sewing machines to lubricate them. I would also recommend a hydraulic one. In general, something is not very viscous.

    Thank you very much for the advice, it seems to work fine so far, I’ve read a lot that the cooler is an important thing that you need to keep an eye on it and began to worry (you know how it happens, what if it happens to me ?!). In principle, I did not even know that there are two coolers in the system block, I have never disassembled this creation, although there are such ideas, I will buy an older PC and start smoking it. maybe I’ll deal with it all. Or maybe try to collect a new one? I understand that it is still small, but my soul is on fire to get into a thread. and further. where to find materials on abbreviations on mothers, and other details, how to find a compatibility chart of all this? (I want to deal with the computer, but I don’t know where to start)

    (I want to deal with the computer, but I don’t know where to start)

    From the study of materiel. In the internet, look for an accessible (intelligible) information according to the principle of operation of the composing computers. Then further, further. further.

    I, in principle, did not even know that there are two coolers in the system unit

    Duc may not be two, but even three (percent, power supply and video), and there are also additional coolers and blovers. And yet. In short: cooling. a separate and very interesting topic on the same forum.

    Checking the fan: way of times.

    Owners of more “perfect” coolers (or if there is no resistance to rotation), I would immediately advise you to turn to checking the cooler for operability. To do this, it does not need to be removed from the installed position. If possible, disconnect the connector from the board. If not, we leave it in place, however, we immediately notice the color of the wires. And to check for operability, we only need two of them.

    The ULTIMATE Laptop Cooling Comparison. Pad vs Vacuum vs Stand

    Whether the connector is in the hands or not, we examine the fan markings. We are looking for voltage:

    For further verification, we need an appropriate power supply. Battery. It, of course, should not exceed the parameter indicated on the cooler in terms of voltage. I have both 12V fans. So a normal 9V “crown” will do. Better new, not addicted. Let’s mount a pair of conductors on the knee to its contacts:

    It is better not to bridge them between each other for a long time: nothing will explode, of course, but the power source may still be useful to you.

    We put the negative wiring of the improvised battery on the black contact of the cooler jack, and the positive one on the red one:

    For clarity, I cut off the connector from the cooler and short-circuit the video directly to the battery:

    Red for “plus”, black for “minus” (there is always a black wire on the cooler). This cooler is working.

    We clean and lubricate.

    What can prevent the fan blades from spinning? Lumps of dust or loose wires. If the first reason is easy to get rid of by cleaning, blowing and subsequent lubrication, then the second option is often accompanied by a characteristic sound. In any case, the fan should be looked directly at. Debris can also get inside the mechanism, jamming the propeller. We can easily diagnose. with a finger on the blades, giving rotation. If there is no resistance to the fingers, the blades rotate easily, skip this paragraph. In the meantime, just clean (with a brush or compressed air). Lubricate as needed.

    We tear off the sticker in the part of the input of the power wires and take out the rubber plug in the center, which protects the mechanism:

    Pay attention immediately to the places where the wires are soldered to the board. If you are the owner of a 4-wire cooler, it is better to immediately clean this place with an unnecessary toothbrush or toothpick. often there are simply cramped contacts there:

    We type on the tip of a screwdriver, toothpick, etc. oil (any technical oil is suitable, vegetable from the kitchen dries quickly, leaving dirt behind) and blot the mechanism in the center, rotating the blades with a finger. So several times:

    well, I have a butter dish for a long time for these purposes

    It is better to put the plug and sticker back in place so that dust does not get here.

    Cooler not working? Come on …

    The fact that the fan is not spinning does not mean that the cooler is not working. precisely, it is inoperative. High-quality products are able to perform their function even after long months of inactivity, being clogged with dust, but with power on (under load), and at the same time not burning out. But also to the old woman, as they say

    So the cooler isn’t working. What options?

    • the mechanism is stuck, something physically interferes with the blades
    • should not spin, because there is no control signal for rotation (the system considers that the temperature threshold has not been reached)
    • lack of electrical signal to the fan itself

    How to disassemble a cooler?

    What for? Cheap and expensive coolers are disassembled until a certain stage: I’m talking about removing the impeller. But most likely you will face a situation when the radio elements themselves are simply inaccessible: the structure is soldered or glued for stability, so YES. the cooler is often a non-repairable device. But this is not the topic of our article.

    Where can you find the richest selection of fans for your computer or laptop? The widest selection of coolers is presented on Aliexpress, including for any video card and a single single heatsink. With this choice, you can put ANY device inside the PC under cooling. Why overpay “sellers” if all the same can be purchased right now, just after waiting a little?

    The cooler does not work, or how to check the computer cooler?

    In this article, I will give a few quick and not-so-great ways to test your computer’s fans for performance. If the cooler does not work, then for what reason, and can it be restored if something happens? A cooling fan, also known as a cooler, is the simplest and most durable mechanism in the womb of a computer. I don’t know what caused it to stop, but there are very few reasons for that.

    Let’s check it out

    In the article I will use the tools at hand that the most explicit humanities student can afford. If the house contains measuring devices, such as a multimeter, you will not find anything new below in the text.

    Checking the fan: method two or very skillful handles.

    And using this option, you can both check the operability and use a working, but unused cooler as a fan from those power supplies that have a 12V output (for example, in a car). And he, the cooler, will be connected via a USB cable. This will require:

    • a used USB cable from any unnecessary device (of course, you shouldn’t spoil a good cable on purpose)
    • working cooler

    Everything is simple here. Cut off the connector from the cable to another device, leaving the USB connector itself. We need wires with the colors you are familiar with: black and red. We connect with the corresponding wires of the cooler. We isolate and connect:

    This is roughly how the most inexpensive USB fans work. Not blown away, but pamper or check just right. For testing, absolutely any USB connector of the “female” type is suitable. By the way, this simple trick will allow you to check four-pin coolers: first connect the “black” contacts of the cooler and the cable, and then alternately connect the red wire of the USB cable to all contacts on the cooler connector. Doesn’t it spin? In the trash heap.

    I warn you. Do not leave a rotating fan powered in this way for a long time! The method is indicated only for checking the functionality.

    Laptop performance test

    A laptop performance test helps you understand which parts of your computer are outdated and cannot withstand high stress. You can evaluate the performance of a laptop using Windows tools and special programs.

    Task Manager

    In the task manager on all versions of Windows there is a tab “Performance” or “Performance”, by opening which, you can see how much resources the system spends on performing a particular task.

    If you go to the “Processes” tab, you can understand which program consumes how many resources. This will not help to check the performance of the laptop, but if you see that the system slows down, although the computer’s scores are normal, then you should check what precious resources are spent.

    Using Windows tools

    If your laptop is running Windows Vista or Windows 7, you can view its performance using the Performance Counters and Tools utility, which measures the performance of your computer. The final grade is set at the lowest value.

    You can find the counter through the control panel by simply writing the name of the utility in the search bar.

    If the test shows that a laptop with Windows 7 has a performance of 3.5-5, then there is nothing to worry about. these are average, quite acceptable values. The maximum score for the “seven” is 7 points.

    If the index is less than 3.5, then you should think about replacing the weak components of the laptop. video card, hard drive, RAM.

    On Windows 8 and 10, the maximum index is 9.9. However, you will not be able to see the estimate using the “Counters” tool in the latest versions of the system. there is no such utility in the control panel anymore. To test the laptop, you will have to use the command line capabilities.

    • Right-click on the “Start” menu, run Command Prompt with administrator rights.
    • Run the command “winsat formal –restart clean”. Wait for testing to complete.

    The laptop test may take several minutes, the system will slow down a little during this time, so it is better not to perform any other actions. At the end of the test, a line with the execution time will appear, after which the command line can be closed.

    To see specific benchmarks for laptop performance, open the C: \ Windows \ Performance \ WinSAT \ DataStore directory and look for a file named with the current date and “Formal.Assessment (Recent).WinSAT.xml”.

    Right-click on the file and open it using a browser or regular notepad. Look for a block of text titled “WinSPR” among the data set. It contains the scores that the laptop received as a result of the test.

    • SystemScore. overall performance score, calculated based on the lowest index.
    • MemoryScore. RAM.
    • CpuScore. processor.
    • GraphicsScore. graphics.
    • GamingScore. in-game graphics.
    • DiskScore. hard drive.

    If you see that the overall score is too low, find a component that is inferior in performance and replace it with more powerful and modern hardware. Then the laptop will work faster and more productively.

    Testing in the AIDA64 program

    AIDA64 is a powerful system information tool for performing software and hardware checks. The program, which can be used for free for a month, includes a number of tests to assess the performance of individual components and equipment as a whole. Available tests are presented on the “Service” tab.

    What can be checked using the AIDA64 benchmarks:

    • Disk Test. Measure the performance of storage devices. Attention: the operation is not limited to reading only, therefore, incorrect execution of the test can lead to data loss.
    • Cache and memory test. check the memory bandwidth when reading, writing and copying, showing the latency.
    • GPGPU benchmark. evaluating the computational performance of the graphics system.
    • Monitor diagnostics. finding the settings you want, calibrating the monitor, detecting possible problems.
    • System stability test. creating a full load for individual components and the system as a whole. During the test, temperature and voltage indicators, fan speed are monitored.
    • AIDA64 CPUID. Provides detailed information about installed processors (supported instruction set extensions, cache size, manufacturing technology, voltage and clock speed).

    The list of testing utilities is not limited to the AIDA64 program. There are also programs like wPrime and Super Pi for the processor, 3DMark06 for graphics, HD Tune for the hard drive. For example, you can use the Battery Eater utility to check the battery life of your laptop.

    Depending on the selected test, the program will show the maximum and minimum battery life of the laptop, without being connected to the network. So you can check all aspects of the laptop, the main thing is to correctly interpret the results.

    Checking through the program

    SpeedFan is a special program for testing all installed fans, which will allow you to quickly establish the status and degree of operation of the device without disassembling it. Using this utility, the user gets full control over the fan operation, and can adjust the rotation speed at a particular temperature.

    • Download, install and run the software:
    • Click the Configure button;
    • Go to Options / Languages ​​and select Russian to Russify the interface.
    • The utility is now ready to work.

    Of course, you don’t have to change the language, because the SpeedFan interface is already quite understandable, and you can see which components are at a normal temperature and which are getting too hot. However, for maximum convenience, you should do all the above steps.

    Once properly configured, the cooling system will perform much more efficiently. Please note that the speed is set in% ratio. In this example, it is 100%. You can track the rotation speed in the “CPU FAN” column, in the picture below you can see that it is “2184 RPM (number of revolutions per minute)”.

    In the event that you have set the maximum speed of the blades, and they still do not provide normal cooling, then the reason may lie in insufficient fan power or general malfunctions during operation. In this case, a complete replacement may be required.

    Checking the performance of the laptop cooler

    In case of malfunctions in the functioning of the cooling system, the first thing to do is to check the operation of the cooler. In most cases, such problems are associated with this particular part. You do not need special knowledge or special equipment to check the health of a laptop cooler. This can be done at home in the following ways:

    • Using the SpeedFan program;
    • By connecting to another device;

    If you find any problems with the cooling system, it is recommended to fix them as soon as possible to prevent overheating and subsequent failure of components. The methods presented below are suitable for laptops of various companies: Samsung, acer, asus, HP, lenovo, so you can not worry about compatibility.

    Hardware check

    The second option, how to check the laptop cooler for performance, is a hardware check by disassembling the laptop. Before disassembling and finding out if the fan is working, carefully consider the instructions for disassembling your device so as not to spoil anything. If the laptop is still under warranty, then do not disassemble it yourself. Better take it to a service center so as not to lose the warranty. Experienced craftsmen will find and solve the problem that has arisen, and you will not have to puzzle over how to check if the cooler is spinning.

    If you decide to disassemble the laptop yourself, then keep in mind that it is not necessary to remove the fan. It is enough to get access to the wires with which it could be connected to another device. Perhaps this will help save you valuable time. To check if the cooler works, you only need a USB cable with a plug on one side and two wires and (-) on the other. Next, connect the USB cable wires to the fan wires (black to black, red to red), after which the USB cable is connected to another computer.

    What do we get? If the cooler does not spin, then the whole problem lies in its performance, in which case it needs to be repaired, if, on the contrary, it rotates without any problems, then the reason for overheating is completely different. Alternatively, replace the thermal paste on the processor and thoroughly clean the entire cooling system. If this does not help, then you will have to contact a specialized service.

    Now you know how to check the fan operation in two simple but effective ways. Choose the most suitable one and be sure that with their help you will definitely find the cause of the problem.
