• Why did the laptop start humming? Why does the laptop make a lot of noise while working?

    Many laptop users, especially those who purchased a laptop for the first time, ask “Why is my laptop humming?” Of course, it would be more correct to ask: “Why is the laptop making noise?”, but this does not change the essence of the question.
    So, it is worth considering two cases:
    1 case. The laptop hums (makes noise) immediately after purchase, i.e. We are talking about a new laptop.
    So if new laptop buzzes (makes noise) during operation, then, as a rule, there is nothing to worry about. The fact is that, as in usual ( desktop computer) the laptop processor cooling system includes a fan, which makes noise during operation.

    Laptop processor cooling fan

    The fan does not work constantly, but turns on only if the laptop processor gets very hot. When the fan turns on, the noise appears.
    Here a second question may arise: “My neighbor (acquaintance, brother, matchmaker) doesn’t make noise, but why does mine make noise?” If your friend has exactly the same laptop model, then it’s worth thinking about. But as a rule, it turns out that we are talking about a different model and the laptop is actually practically silent during operation.
    What is the reason for this difference? The reason is simple - laptops have different configurations, i.e. simply put, different internals. We are talking about the processor, hard drive, RAM etc.

    The components of your computer heat up more than the components of your friend’s laptop; for this reason, your laptop has a more efficient fan (cooler) with higher speeds or large size blades. Naturally, such a fan will make more noise.

    Let me give you one example from practice. For a very long time I had the opportunity to hold in my hands a laptop made on the basis of the Celeron-700 processor. When it was running, even under load, I noticed that the fan made virtually no noise.

    Not long ago, I was holding an eMachines-430E laptop based on the Semprom-100 processor. The fan also did not make much noise when operating. As for my home Lenovo laptop B550 processor based Intel Pentium T4400, the fan is quite noisy during operation. Why? Yes, it’s just that the processor of my laptop is “more powerful” than the processor of the eMachines-430E laptop and generates more heat during operation.

    Case 2. Previously, the laptop did not hum (did not make noise), but now the noise is getting stronger. Actually there are two visible reasons:

    1. A certain amount of dust has accumulated in the laptop case and it’s time to clean it.
    2. The cooler bearing is worn out and the cooler needs to be replaced. In such cases, some comrades suggest lubricating the fan without changing it. I am against such experiments and recommend replacing the fan with a new one. Here you should immediately note that different fans have different noise levels during operation and you should choose a cooler with minimal noise.

    If your fan hums too loudly when working with your laptop, then this instruction designed especially for you. In this article we will look at why the fan is noisy and what should be done to get rid of the annoying sound.

    Reasons

    There are several obvious reasons why a laptop is buzzing a lot:

    • Overheating and, as a result, high speed rotation of the cooler blades, which leads to high level noise.
    • Dust and dirt in the cooling system, which interfere with its full and uninterrupted functioning.

    Everything is quite simple, but there are a couple of nuances. For example, if your device makes a lot of noise only when turned on certain games or programs, then you should not worry and take any action, as this is quite normal.

    All that is needed in this situation is preventive action every six months in the form. If your laptop makes a lot of noise when programs that do not load the computer are running, you should try to do something.

    What actions can you take?

    There are several options to correct these problems:

    • Cleaning from dust and dirt;
    • BIOS update;
    • Using a program to change the cooler rotation speed;

    Cleaning from dirt and dust

    If the cooler in your laptop begins to make a lot of noise and overheat, this may mean that it is excessively dirty. It is recommended to clean your laptop regularly, but you don't have to take it to the service center, because everything can be done at home.

    If you decide to clean your laptop yourself, you need to:


    If there was a lot of dust in the device, then after cleaning you will immediately notice a positive result: the computer will heat up less and work much quieter. However, prevention does not always help, for example, when the mechanism wears out, in which case complete repair may be required.

    Updating BIOS and drivers

    Developers often release driver and BIOS updates that fix previously made errors. It is in the BIOS that the temperature of the sensors corresponds to the speed of rotation of the cooler blades. Therefore the update software may help eliminate fan noise.

    Sites with necessary drivers for users of the most popular models:

    • Acer;
    • HP;
    • Toshiba;
    • Lenovo;

    Changing the cooler rotation speed

    If the fan in your laptop makes too much noise, then perhaps a special SpeedFan program, which will allow you to change the speed of rotation of the blades. She gets it all necessary information from the temperature sensors that your laptop is equipped with, and makes it possible to take into account the received data. By correctly adjusting the indicators, you can eliminate the cooler noise by limiting its rotation speed.

    If the processor temperature rises too high, then the program will automatic mode will start the fan on full power to protect the laptop from overheating. Therefore, if after the settings you made, the laptop began to make noise, then there is nothing to worry about.

    How to prevent and reduce laptop noise?


    Now you know how to quickly and without any problems reduce fan noise yourself at home, and you can help not only yourself, but also your friends and family.

    Or, for example, if you work with high-quality video materials, the cooler immediately makes itself known - a certain hum appears. During the day, when both the house and the street are filled with sounds, this noise is not particularly noticeable. But during night work, when you don’t want to wake up your family, the hum of coolers and the insides of the laptop really attracts attention. Why is it noisy and what needs to be done to make the laptop work quickly and silently - read on.

    Why is my laptop noisy?

    The internal structure of the laptop involves three parts that can serve as a source extraneous sound: cooler, hard drive, drive.

    1. The cooler is always noisy, as it is a small fan that circulates air to cool the “insides” of the laptop. If you do not give the laptop a heavy load, the noise level from the fan will be barely noticeable. Increasing the load on the processor immediately increases this hum, as the cooler accelerates in order to manage to supply cold air inside the laptop case and prevent overheating of spare parts.
    2. CD/DVD drives are also very noisy. Now, of course, the information on disks is not very popular, but even when empty, the drive sometimes produces loud sounds, and when reading or writing to the disk, the noise becomes very loud. There are programs that regulate the speed of data exchange in the drive, but they significantly slow down the operation. The best solution This problem will be solved by timely removal of the disks upon completion of work with them.
    3. The last reason The noisy operation of a laptop lies in the functioning hard drive. It is its magnetic heads that make grinding sounds with clicks. This does not always happen, but only with intense work: reading “heavy” information, the “hard” accelerates and begins to work in an enhanced mode.

    What to do if the laptop is noisy and overheating?

    To improve the performance of the laptop and to make the sounds it makes quieter, there are several optimal ways, one way or another connected either with the features external device, or with laptop software.

    Bios and Driver Update

    Many users, when upgrading the technical components of their laptop, often forget about upgrading the software. It is no less important for the sufficient performance of the equipment, especially when it comes to updating (flashing) BIOS systems and drivers. If you visit the website of the laptop manufacturer once every six months or a year and update the software in the form of, at a minimum, drivers, this will allow you to get rid of moments when the laptop makes noise or gets very hot. In addition, improving the software will significantly increase the speed of the laptop computer.

    Important nuances and tips for updating the BIOS:

    • do not download new versions from anywhere other than the official website, and only after you find out the model;
    • if the update occurs using official programs, the process becomes simpler and clearer. There is also a “but” - you take a risk, since anti-virus applications and other third-party processes can cause the laptop to freeze;
    • During the update, you need to protect yourself from any problems with the electrical network, as this will motherboard may be significantly damaged;
    • It is recommended to save the old, familiar BIOS variation on a separate medium in advance, in case the update performs poorly;
    • It is recommended not to select alpha versions that are in the testing process.

    Flashing the BIOS optimizes the processes in the laptop, including the rotation speed of the cooler.

    It's easy to update drivers: visit the manufacturer's website, download them individually or in a pack, run them and, following the prompts, install the drivers like a regular program.

    Cleaning from dust

    When small particles of debris get into the cooler, they slow down its operation, make it difficult to rotate, causing loud buzzing and noise. Regular cleaning will help maintain the performance of the machine and avoid loud noises during operation.

    1. take brushes with synthetic bristles - they shed less and clean the surface of the “insides” of the laptop better;
    2. It is recommended to clean your laptop at least once every six months;
    3. when cleaning, it is better to also change the thermal paste and lubricate the moving parts of the coolers;
    4. It is recommended to carry out the cleaning process on a table, and not on a bed, floor or chair, since otherwise all the necessary screws may be lost;
    5. to unscrew the bolts, it is more convenient to use a magnetized one, so that it is easier to remove the screws from the grooves and not lose them;
    6. It is advised not to clean laptops under warranty yourself, since opening the back cover will void the warranty;
    7. Experts strongly recommend that before disassembling a laptop, find materials on how to do it correctly;
    8. necessary tools for physical cleaning are: a set of screwdrivers with suitable cue balls, thin brushes, alcohol wipes.

    Regular care of your laptop, expressed in cleaning dust and changing thermal paste, will reduce the noise of the operating fan and protect the laptop from heating up.

    Reducing the cooler rotation speed

    Elimination of excess noise is also carried out locally. You can download software that controls the fan speed. Such programs detect temperature changes inside the laptop case, automatically adjusting the rate of movement of the blades - so the cooler will work with optimal efficiency, and you will avoid a lot of noise.

    Often, such utilities are not needed for the high-quality performance of a laptop; however, some laptop models require this fan speed control, since they initially do not have sufficiently sensitive temperature sensors.

    Due to the low sensitivity of these sensors, the cooler may not slow down immediately as soon as the temperature drops, but after some time. This delay leads to rapid wear of the cooler's moving parts and constant noise.

    You should use such software very carefully, as there is a possibility of the program crashing and, as a result, dangerous overheating of the laptop.

    Reducing hard drive noise

    The grinding noise of your device is nothing more than the positioning of the read heads of the hard drive, they are the ones making the loud noise. Don’t rush to panic, cover your ears, or look for a new device - just look at the settings of the hard drive itself. There is a head monitoring function, a priori it is turned off by default. With the help special programs you can turn it on, thereby reducing the reading speed and removing noise. Of course, this slightly reduces performance, while at the same time significantly adding years of service to it.

    Most the best program For this they consider quietHDD. It's not difficult to understand:

    • download and unzip the program, run as administrator;
    • Find the application icon on the taskbar;
    • call context menu right click and select “Settings”;
    • go to the “AAM Settings” tab;
    • move both sliders to the left to the minimum value;
    • Save everything with the “Apply” button.

    After completing this algorithm, the working parts of the hard drive will slow down, and it will stop humming, grinding or clicking. In order for the application to start working simultaneously with turning on the laptop, you need to copy the launch file to the Desktop, mark Run as administrator in Properties and move this file to Autorun, which can be found in the Start panel.

    Programs for changing the cooler rotation speed

    SpeedFan is rightfully considered the simplest and most functional software for controlling a cooler. A clear interface and automatic operation are the best companions for a program of this nature.

    The application will easily adjust the rotation speed of the coolers - this will not cause any difficulties for you:
    1. install the software;
    2. run it;
    3. in a matter of seconds, the program will collect information about all working laptop coolers and display the data in a list;

    4. in the working window, remember two blocks of information.

    The first block shows the speed of the cooler, expressed in the number of revolutions, and the program determines which fan belongs where. Sometimes, of course, she is not able to complete this task and then you can change the indicators at random.

    The second block is changing the speed of coolers by percentage. By experimenting with these indicators, you can adjust the cooler speeds and, trusting your hearing, choose an acceptable speed. Please note that your right choice will also affect the temperature inside the laptop - it very much depends on the intensity of the blades. Therefore, you need to pay even more attention to the speed of coolers: the volume of the device and the cooling of its “filling” depend on it.

    To enable SpeedFan when you start your computer, click on the fields in the equivalent program option items. You can enter them by clicking on the “Configure” button and selecting the “Options” tab of the same name.

    The second good program for monitoring the cooler is MSI Afterburner. This utility works exclusively with coolers. Having installed and opened the program, you can see that there is only one cooler adjustment slider. Since by default it works in automatic mode, for self-configuration you need to switch to custom mode. If the video card cooler is very noisy, then you need to select the optimal value for its rotation speed. The parameters take effect when you click the “Apply” button.

    The right window of the application shows graphs of temperature changes, blade speed both as a percentage and in revolutions per second.

    This program is also known for the fact that it has a function that allows you to set different cooler speeds under different temperature conditions. You can find this function by going to “Settings”, and then opening the “Cooler” tab. Select “Custom Auto Mode”. Set additional points on the graph that will program the fan. After the settings, the program will independently adjust the speed to the user’s.

    All the actions described in this article are aimed at timely care of the laptop, both from a purely technical side and from the software side. And if regular cleaning laptop from dust is necessary in any case, then experts advise using other methods of reducing noise only in situations where the laptop is humming outside heavy loads, games or resource-intensive programs.

    Updating drivers should be done once every six months to a year if the new software on the official website has significant differences from the existing one, and the BIOS should not be updated unnecessarily. However, most often the laptop is excessively noisy precisely because of a dirty cooler and old thermal paste, so getting it to work quietly will not be difficult.

    You must understand that for the laptop to operate correctly, the system supports optimal temperature processor. By loading your laptop with numerous tasks, you yourself can provoke increased work of the processor, and with it the fan.

    If the cooler on a laptop is noisy, it means that something is causing it to work harder. Such “provocateurs” can be gaming applications, viruses, or simply a large accumulation of dust on the fan blades.

    To effectively help your technology, it is important to thoroughly understand why the laptop gets hot and the fan makes noise.

    Intensive work and, accordingly, excessive noise are provoked by many reasons. Moreover, if you don’t understand why the fan in the laptop is noisy, what to do will be difficult to figure out.

    Most users are absolutely sure that the cooler is noisy only when it is excessively dirty. Indeed, it is important to give your laptop targeted cleaning over time. However, it is stupid to say that only dust can act as an obvious culprit, due to which the fan is very noisy. In this case, it is useful to “roll up your sleeves” and fully immerse yourself in theoretical material, trying to find the answer to the question why the laptop makes noise when working.

    Anyone can understand the reasons if they have a strong desire.

    Eliminate maximum CPU load

    A laptop may make a lot of noise when operating if its processor is overloaded. Even if you are sure that you did not run multiple tasks, it is important to verify with your own eyes that this is the case.

    To do this, first launch the “Task Manager”. It’s easier to do this by holding down three keys at the same time: Alt, Ctrl and Delete. The percentage of processor load will be indicated at the bottom of the window that opens.

    You should suspect something is wrong if the download percentage reaches 100% in a situation where you have not run any programs in large quantities on the laptop.

    In this case, you will have to find that ill-fated program or process that is maximizing the CPU resource of your laptop.

    Having found such a process, hover your mouse cursor over it and right-click to open it. additional menu. In it, select the line “Open file storage location”. After these actions, a window will open showing the storage location of the executable files of the process, which is heavily draining the CPU resource.

    If you find that the location of the process files is the Temp folder, you can safely terminate the process to relieve the load on your system. It is all the more important to stop this ill-fated process if among the existing files there are those that are accompanied by incomprehensible names, more reminiscent of a simple set of letters, and also have the exe extension.

    After you remove the unwanted process, be sure to restart your laptop for all changes to take effect. Now listen to whether the fan is noisy, whether the laptop gets very hot during operation or not. If the problem is resolved, you can be happy with the result and finish studying the theoretical material.

    Unfortunately, the unwanted process is not the only reason, so we have to further figure out why the laptop gets very hot and noisy, and what to do in such cases.

    BIOS setup

    Sometimes the reason that the cooler makes incredibly loud noises when the laptop is running can be incorrect settings in BIOS. This reason is most often typical for users working on desktop computers, although sometimes it also occurs among those who own a laptop.

    If you have checked all the processes in the “Task Manager”, made sure that there is no reason for alarm, but the cooler continues to make a lot of noise, click on reboot, and then relaunch system, enter the BIOS.

    Go to the Power tab located on the horizontal bar at the top.

    Enter Power in BIOS

    Use the arrows to scroll down to the HardWare Monitor option.

    If you find that the Q-Fan Function parameter is set to Disabled, then this parameter is disabled. Enable it by setting the Enabled option.

    Now, again using the arrows, go to the CPU Target Temperature parameter, which is responsible for adjusting the temperature. If a value with a low temperature is set there, then this may be the reason why the cooler is very noisy.

    Click on this indicator to open a window for selecting the desired temperature, select a value indicating a temperature of about 50 degrees. Even this adjustment temperature regime can solve the problem, your laptop fan will run quite quietly.

    Cleaning the Temp folder

    The Temp folder is designed to collect all unnecessary “garbage”. Unfortunately, among absolutely unnecessary files Quite often viruses are hidden that negatively affect the operation of the laptop as a whole and its individual peripheral devices. Experienced users strongly recommend clearing the Temp folder in a timely manner, relieving the system and preventing excessive noise that the fan may make.

    There are several ways to clear the folder with temporary files. You can get to it by opening drive C, and then, sequentially opening Users folders, then go to the user folder, it has the name that you assigned to the laptop at the time of installation operating system. Next, open the AppData, Local folder, after which it will be easy to find the Temp folder. Everything that is in it can be ruthlessly removed.

    By the way, quite often viruses are removed that functioned very secretly, so the PC owner did not even notice them. Only after cleaning Temp folders the user may find that not only the fan began to work correctly, but all other tasks began to be completed quite quickly.

    Dust removal

    Of course, we cannot discount the fact that the reason why the fan is humming very loudly may be banal dust, which penetrates inside, accumulates and settles in a large layer on the cooler blades, interfering with its correct operation.

    What to do in this case is probably clear even to a beginner. It is important to clean your laptop by removing dust from all internal devices. Large quantity dust also provokes a situation in which the laptop gets very hot for no apparent reason.

    Removing dust with a wet cloth is, of course, strictly prohibited. You can use the services of service center technicians who will quickly restore order. But you can also try your own and, following the instructions, clean it yourself.

    Experienced users recommend doing self-cleaning only when warranty period has expired, otherwise the warranty will be void. Cleaning is carried out with the laptop turned off, so make sure it is not in sleep mode.

    All parts are released slowly without subjecting them to additional pressure. Remove back cover, use cotton swabs to remove the layer of dust. And you can also use a can of air to blow out dust from difficult places.

    The cleaning process can take a long time because it cannot be rushed, but it also requires extreme care. After cleaning is completed, close the lid, tighten all the screws, and only then connect the laptop.

    If the reason was dust, then after turning on the cooler will no longer make noise and irritate you. And also you will notice that more laptop does not heat up during its operation.

    It would be even more effective to subject your laptop to a complete cleaning, but this can only be done by experienced users who can easily understand the sequence of disassembly, detaching even small parts, correctly removing old thermal paste and applying new one.

    Process complete cleaning is accompanied by some difficulties, so in many cases it is better to entrust your equipment to experienced craftsmen. Any awkward movement can damage both the device and the microcircuit, then the problem when the laptop heats up during operation and the fan rotates vigorously will seem so small and completely insignificant.

    So, if the laptop cooler confuses you with its loud operation, you can on our own try to restore it correct operation. By stopping unwanted processes, deleting temporary files, and with them possible viruses, by cleaning the cooler from dust, you will not only get a quiet, but also fast work laptop.

    In this article, you will learn what to do if your laptop makes a lot of noise, which not only reduces the comfort of work, but also creates an alarming feeling that something is wrong with the computer. It contains all possible reasons, according to which the laptop cooler begins to rotate more actively, their symptoms and possible options for eliminating the sources of the problem.

    Advice. The term “noisy” means increased noise emission from the fan cooling the central processor. Noise hard disk is not considered.

    If the device is several years old from the date of purchase, and its operation is accompanied by increased generation of noise that occurs due to the accelerated rotation of the cooler, this is a reason to think about it.

    During long work under heavy load increased speed ventilators are the norm. The processor processes large amounts of data (3D games), which causes it to heat up more, and to prevent it from overheating, the system automatically increases the fan speed. By the way, if you are faced with the “cpu fan error” problem, we have a separate material on solving it.

    So if you watch movies in high quality or playing games, it is somewhat normal to hear a lot of noise, especially after using the device for several hours. It’s another matter when the problem appears immediately or a few minutes after the device starts.

    Is high cooler volume bad?

    In addition to feeling discomfort and thinking that something is wrong with the laptop, increased noise from the CPU cooling fan is a sign of significant heating or overheating of the CPU.

    And the operation of any components at elevated temperatures, for which they were not designed to operate or were designed for short-term exposure to such conditions, causes their faster wear. And this is in best case scenario. At worst, the computing device will simply overheat and fail.

    Modern laptops have implemented a mechanism to protect the PC from such cases - when it reaches critical temperature the device simply turns off in emergency mode.

    Causes of strong fan noise

    In fact, the only source of the problem is increased operating temperature central processor. And there can be many root causes for its overheating. The main one is clogging of the heat-removing metal tubes (radiator) with dust and other small particles (lint, hair, wool).

    Due to the fact that the airways through which air passes are partially blocked foreign objects(let's call dust and other small debris that way), the hot air flow diverted from the central processor is partially dissipated, hitting the radiator mesh.

    There are several solutions to the problem:

    • increasing the cooler rotation speed;
    • purging or cleaning the cooling system;
    • replacing thermal paste, lubricating and/or replacing the fan.

    How to solve the problem in the case of each of the options will be discussed below.

    High temperature

    Signs that the culprit is loud noise is a high temperature

    In principle, increased processor temperature is the main culprit of noise. And there are several explicit and indirect confirmations of this.

    • Applications that display data from computer sensors – SpeedFan, HWMonitor. In them you can find out the current and maximum temperature recorded during the application’s activity and compare it with data on the processor’s operating modes on the website of its manufacturer.
    • The noise appears some time after starting a game or playing a movie (performing another resource-intensive task).
    • A very hot case in the area where the CPU is located and where the hot air flows out from it.
    • The device works slower, freezes, slows down, and sometimes turns off or restarts without permission.

    Changing the fan speed

    Let's consider what to do if the laptop makes a lot of noise when processing large amounts of information, for example, converting video, packing/unpacking something, installing or running games, watching movies in HD and similar cases.

    This is done via UEFI (in some old BIOS a similar function is also present), and through special software, for example, SpeedFan. The advantage of the utility is the ability to control the speed of fans installed on GPU and displaying temperature trends of key hardware components.

    By manual change The initial fan rotation speed in 5% increments can be either lowered if the device is very humming without load or overheating, or increased when the CPU temperature is close to critical or simply increased.

    Rice. 1 Adjusting the cooler speed in SpeedFan

    Unfortunately, the application is not updated often, which is why it may not be supported by some new products on the laptop market, and is also not compatible with a small percentage of computers due to the specificity of their hardware shell.

    Controlling the fan speed in BIOS/UEFI is no less simple, but in each firmware version from each manufacturer this parameter may be called differently and located in different submenus. The instruction manual or your own ingenuity will help here.

    Blowing out the cooling system

    If the first option does not solve the problem, or rather it is caused by dust and small specks stuck to the cooler blades and radiator mesh, then we move on to the option of purging the cooling system. This is done in several cases:

    • when the device is still under warranty, and it is not advisable to void it by disassembling the case for cleaning;
    • the user does not have the skills to disassemble laptops or is afraid to do so, and going to a service center is not a solution.

    In this case, you will need a special canister filled with compressed air (sold in specialized stores) or a powerful vacuum cleaner, preferably turned on for blowing (reverse). In extreme cases, a hair dryer will do, but its effectiveness will be extremely low.

    We take the device with a spray can or vacuum cleaner to a balcony or other room that you don’t mind getting dirty with dust. This should be done in calm, dry weather if the procedure is carried out on an unglazed balcony or in the yard. After several blows with a stream of air, the laptop can be turned on and tested.

    It happens that blowing does not bring almost any benefit, or a few months after it the laptop begins to hum just as loudly. Then you will have to unwind it and thoroughly clean both the cooling system itself and get rid of dust under the back cover of the case.

    How to quickly and easily clean your laptop from dust with a vacuum cleaner?

    Let's consider a simple household method of cleaning a laptop using a vacuum cleaner, so to speak, at home. We'll also look at why it's important to clean your laptop and how to determine if it's worth cleaning.

    Removing dust

    You should undertake this when you are sure that you will successfully disassemble the laptop case without breaking its fasteners, carefully follow all the recommendations below, and disassembling the case will not void the warranty (it has already expired). To remove small dust particles you will need:

    • screwdriver for unscrewing bolts;
    • preferably a kit for opening laptops and other equipment (if you don’t have one, you can use improvised tools);
    • a couple of napkins, a piece of cloth, cotton swabs or something similar;
    • vacuum cleaner, cylinder compressed air or hair dryer (optional).

    The sequence of actions for removing dust will be as follows.

    1. We disconnect the laptop from the network and remove the battery from it.

    Rice. 2 - Remove the battery

    1. Disconnect all wires and external devices.
    2. Unscrew the bolts of the back cover.

    Advice. You should be careful here: the bolts may be under stickers or rubber feet.

    Rice. 3 – Remove the back cover

    1. We remove the entire back cover or the segment where the processor with the entire cooling system is located.

    Advice. If you do not have tools for disassembling tablets/laptops, find a replacement and carefully, so as not to damage various latches, disassemble the case.

    1. Using fabric, cotton wool, or simply by hand, we remove large pieces of debris, often compressed or welded together.

    Rice. 4 – Remove dust from the blades

    Advice. Remaining dust can be blown off using an air can or a vacuum cleaner. When there are no such devices, carefully remove them using a napkin or a cotton swab. If you want to blow off the dust, do it outside or in a utility room.

    1. If tiny air ducts in the radiator mesh are clogged with dust, the cooler and radiator can be unscrewed and thoroughly cleaned one by one.

    Rice. 5 – Remove the cooling system

    1. Carefully assemble the laptop, performing all steps in reverse order.

    Cooler maintenance

    At the point of contact of the radiator with the surface of the processor, a special substance - thermal paste - with high thermal conductivity is applied. It removes excess heat from the CPU to the radiator, which is cooled by a fan by removing hot air outside the case. Over time, thermal paste loses its properties and copes with its intended functions worse, and it has to be replaced.

    You can do this yourself.

    1. As in the case of removing dust, we disassemble the laptop, letting it work a little or warming up the processor area with a hairdryer so that the thermal paste becomes more viscous.
    2. We remove the cooler and carefully disconnect the radiator from the processor, if necessary, heating the place of their contact.

    Rice. 6 – Remove the cooling

    1. Carefully clean the contact pad from any remaining thermal paste.

    Rice. 7 – Removing residual thermal paste

    1. We degrease the surfaces with an alcohol-containing substance (cologne) and let them dry completely.
    2. Apply a thin layer of new paste from the tube, using a syringe or plastic/cardboard.

    Rice. 8 – Applying thermal paste

    1. We put back the radiator with cooler.
    2. Putting the body back together.

    How to replace the thermal paste of the processor and video card on a laptop?

    If you are interested in how to replace the thermal paste of a processor and video card on a laptop, then this video is for you. In it, I briefly, bypassing the obvious and understandable steps for everyone, explained how to do this after disassembling the laptop.

    Fan repair/replacement

    The last thing that can help the user is replacing or restoring the cooler. Over time, the ball bearings in it can wear out or the lubricant in which they move can be depleted. Try to remove the back cover of the case in order to get to the cooler, and drop a thick lubricant: grease or lithol into its center (usually you have to tear off the sticker). If this doesn't help, possible option developments will involve the purchase and installation of a new cooler. The need to replace it may be indicated by:

    • the fan grinds throughout its operation;
    • the cooler does not rotate at the slightest touch of a finger;
    • The device is wobbly or loose.

    Advice. If you are not confident in your strengths and abilities, contact a specialized center for help in cleaning your laptop from dust, replacing thermal paste, cooler, or repairing it.

    And finally, a recommendation: to improve the cooling of your laptop, you can purchase a special table-stand with a built-in cooler, which will not only make work more convenient, but will also blow cold air from below the case.
