With the onset of heat, not only people want to hide in the shade, plunge into the sea or retire with air conditioning. The computer is also sensitive to high temperatures, which are harmful to its components. To protect against overheating - processors, video cards, power supplies and other hot components are equipped with heatsinks and fans. But sometimes there comes a moment when they fail. So,the processor overheats and the computer turns off - what to do? How to protect the "electronic assistant" from destructive high temperatures and restore its performance? There are several ways. Which one to use depends on the cause of overheating.

What to do if the processor on the pc overheats?

When overheating is detected, you should first understand why this is happening. The reasons for this unpleasant phenomenon are of a common nature - the inability of the cooler to remove the heat generated by the cores. But the specifics of the problem in a particular case may differ. Ways of solving the problem with overheating depend on it.

Dust

No matter how clean the room is, you can't get rid of the dust completely. Its source, among other things, is the person himself: skin cells are constantly renewed, and their dead layer gradually disappears. This process is imperceptible, but it happens all the time. Upholstered furniture, pillows, mattresses, feather beds, blankets tend to accumulate dust, from which it also gets into the air. The fans in the computer create a differential pressure by sucking in air. Small dust particles from it get inside the system unit and settle on the PC components. Showering twice a day and cleaning daily can slow the build-up of dust, but not stop it.

Deterioration of contact with the cooling system

It will not be possible to connect the heatsink to the processor crystal with a "dead seam". In order for the metal base of the cooler to better contact the crystal and there is no air between them, thermal paste is used. The cooler itself is fixed on the chip with screws or special clamps for tight contact.

Thermal paste (especially the cheap one) has a limited shelf life. Over time, under the influence of temperature and atmospheric air, it can dry out and degrade, changing its structure. It turns from a heat conductor into an insulator.

The cooler, too, can be deformed due to temperature changes. The motherboard and the radiator mounts also bend. As a result, the chip does not adhere to the base of the cooler so tightly, a microscopic layer of air forms between them, which is a good insulator for heat.

Fan wear

The service life of a modern fan is thousands and tens of thousands of hours, but it is still limited. Bearings, shafts and bushings wear out and dust and metal particles get into the grease. As a result, the fan either starts to "walk" (which is unpleasant because of the noise, but not scary), or rotates worse. In this case, the air flow decreases, the performance of the cooling system decreases.

Heatpipe degradation

Heat pipes used in coolers are hollow copper capillaries filled with refrigerant and sealed at the ends. One end of them is in contact with the hot part (processor crystal), and the other - with the cold part (cooler radiator). The refrigerant substance is selected according to its chemical composition in such a way that at room temperature it is in a liquid state, and when it is significantly exceeded (40 degrees and above) it evaporates. Steam from the hot area rises to the cooler fins, where it condenses and flows back down, cooling the processor. This process runs cyclically and continuously.

Substances-freons have a great fluidity. They can seep through walls made of materials that are impervious to water (such as rubber and latex). With the degradation of heat pipes, microcracks, invisible to the human eye, can form on them. But even they are enough for the gas to evaporate. Without refrigerant, the tube loses its thermal conductivity and does not have time to transfer heat from the processor core to the radiator, which leads to overheating.

Incorrect setting

Overheating can also occur from incorrect actions by the user (or service personnel). Limiting the speed of coolers (it does not matter, in the BIOS or using programs), to eliminate noise, reduces the power of the cooler, and it can no longer cope with the task. Many computers also have a BIOS setting for shutdown temperatures. It allows you to manually set the temperature threshold, upon reaching which an emergency shutdown for cooling will occur. Too small a number set in this item leads to shutdowns even in the absence of dangerous heating. For example, at a threshold of 60 ° C, the computer can work properly in winter (when the room is about +20 ° C), but turns off in summer (when the room temperature rises to + 25-30 ° C).

The processor is overheating: what to do after studying the reasons?

When the processor on the computer is overheating, what to do - depends on the cause of overheating. All of them are listed above, it remains to diagnose. To do this, you need to disassemble your computer or laptop and get to the coolers. With a desktop PC, it's easy - just remove the cover. In the case of a laptop, it is advisable to find a video disassembly instruction, or at least a guide in pictures. It is recommended that you discharge static electricity from yourself before disassembling. The easiest way is to take off clothing that can spark in the dark and touch a grounded object (such as a battery) with your hand. You also need to get a tube of thermal paste.

Cooler cleaning and thermal paste replacement

Dust clogged radiators are hard to miss.

They need to be disconnected and thoroughly blown out with a vacuum cleaner or compressor.
Cleaning the boards and other PC components is also helpful, but you need to be wary of static electricity.
It is advisable to first clean everything with a brush made of antistatic synthetic material, and only then blow it under pressure.
When disassembling, it is also required to assess the condition of the old thermal paste: it should not be dry, hard and crumbly. If one of the signs is present, she is also guilty of overheating.
Wipe off the old layer of paste, gently wipe the top of the processor and the bottom of the cooler with a napkin or rag.
New thermal paste is applied to the processor, this is done neatly and in a thin layer. In this situation, it is very easy to spoil the "porridge" with "butter". The paste should smooth out uneven surfaces of the crystal and cooler, but not cover them with a greasy layer.
You can smooth out the thermal paste and remove excess with a plastic card.
After applying the paste, you can return the cooler to its place, fix it.
After the correctness of the installation is checked, you can turn on the computer and test it for overheating. This requires the programs HWMonitor (to view temperatures) and LinX (to create the maximum load on the processor).
If the temperatures are normal (no higher than 70 ° C for a desktop PC or 75-80 for a laptop) and the computer does not turn off, the problem is solved.
If the temperatures do not exceed 60 ° C, but the PC turns off, you need to go into the BIOS (press Del, F1, F2 or another button indicated in the instructions when turning on), find there an item like PC Health, Hardware Monitor, Termal Config (again, you need to look in the instructions for a specific board) and look at the Shutdown Temperature column in it.
If it is turned on and a low temperature is indicated, you need to turn it off or set a threshold of 70-75 ° C for a desktop, 75-80 ° C for a laptop.
Then press F10, save, reboot and test again. If this does not help, the reason is the cooler.

The processor is overheating anyway, what should I do?

If after cleaning it doesn't matterthe processor overheats and the computer turns off, what to do further depends on the diagnosis. It is necessary to assess the condition of the heat pipes on the cooler (if any). In case of suspicion, the radiator with tubes should be replaced. If the radiator is without pipes, carved from a solid block of aluminum, and the processor is powerful, it is better to replace the cooler. Such "blanks" are only suitable for economical processors, such as Core i3 or Celeron, but they are not enough for some AMD FX or Core i7.

For a desktop PC, you should choose a cooler in ordinary stores, taking into account the type of mount (socket), the maximum supported power (TDP) of the processor and the rotation speed. You can look at the TDP of your CPU on the manufacturer's website (Intel or AMD), or check it on a specialized computer resource. It is advisable to take cooling with a margin. For a processor with a TDP of 60W, you can buy a cooler rated for 80-100W. For a 100-watt model, a cooling system for a CPU with a heat dissipation of 120-140 W does not hurt.

GPD is preparing to release a new game console Win 2

Many initially expressed noticeable skepticism about the feasibility of producing pocket Win-notebook devices. These projects include the GPD Pocket notebook, which we have already talked about many times, as well as the GPD Win model. The main complaint about such products was dubious demand against the background of a very significant cost.

Sometimes, because of this, it starts to glitch, slow down, or even reboots on its own initiative. How do you know when it's time to clean up?

Diagnostics of computer overheating

Most important components - processor, hDD, video card, power supply, motherboard

1.1. Overheating processor

Symptoms of the problem: programs freezing, unexpected restarts or shutdowns of the computer, blue screen... The consequences of this state are the degradation of the chip, the processor can work, but with errors. If the processor has undergone degradation, it will not be possible to repair it, only throw it away.

1.2. Overheating of the video card

The computer freezes while watching a video, after a few minutes of playing, the computer restarts, a blue screen appears, graphic artifacts on the screen, the image disappears during operation, a notification may appear.

1.3. Hard drive overheating

If the hard drive overheats, the computer suddenly freezes, clicks are heard from the system unit, the system does not boot. Typically, these signs appear when overheating has caused irreparable damage. If you want to restore the data that was recorded on the hard disk, you can do this only through the service center. The hard drive itself cannot be repaired, but the information can be copied to another medium.

1.4. Power supply overheats

Dangerous symptoms appear: during operation, there is a burning smell, shutdown immediately after start-up, an unexpected restart occurs, games or videos freeze. The consequence may be the failure of the components of the power supply, but repairs to a service center will cost you inexpensively.

1.5. The chipset on the motherboard is overheating

If the chipset on the motherboard has overheated, this manifests itself as follows: the keyboard, mouse, USB crashes, no connection to drives and hard drive, computer freezes, unexpected reboots occur. As a result, the chipset can degrade. If you do not monitor the temperature motherboard, later you will have to buy a new one, since repairs are very expensive.

1.6. Overheating of other computer components

In addition to the above, various batteries on the motherboard are heated. For effective cooling, they must be equipped with radiators. But some manufacturers, in order to save money, do not do this, hoping that the motherboard will work exclusively in normal mode... Therefore, at least one fan must be running to cool the components by natural air movement.

1.7. Reasons for computer braking due to overheating:

Most often, computer overheating is manifested by its deceleration during operation. Usually this symptom is not visible immediately, but some time after turning on the computer. With very high temperature the processor is not working efficiently as it tries to lower the temperature. This process is called throttling. Depending on the model, the permissible processor temperature ranges from 65 to 80 degrees.

Throttling works on modern processors and video cards. So if the games freeze or slow down, it is most likely overheating.

1.8. Causes of computer restart due to overheating

Windows - a complex system. If once the processor issued an error during calculations, then everything is violated. This will result in a failure BSOD , if it is more clear - "Blue screen of death".

BSOD is a serious error that cannot be ignored. By default, the system is configured in such a way that upon detection BSOD The PC rebooted itself. Thus, if overheating occurs, a blue screen appears and the computer restarts. However, the "blue screen of death" may just hang. The reboot process after the appearance BSOD disconnect as follows: through the Control Panel, go to the System, then to Advanced system parameters. In them, open Startup and Restore - Options, from the option Perform automatic restart, you need to uncheck the box and confirm your decision.

In fact, the reasons for the appearance BSOD many - malfunctioning drivers and programs, errors on the hard disk.

1.9. Computer gets hotter over time - why

One of the reasons is the amortization of cooling components and dust. To clean the heatsinks and other components of the computer, it is advisable to use fans that suck in the deposited dust. Overheating also occurs due to a large accumulation of dust.

Over time, fans wear out, as a result of which they can constantly make noise, spin at a slower speed, or stop altogether. The thermal conductivity of the thermal interface deteriorates. Thermal pastes and thermal pads, which provide high-quality heat transfer from the processor to the heatsink, require cleaning and replacement.

2. We measure the temperature

There are many sensors inside the computer. They measure component temperature, voltage, fan speed. Their exact number differs depending on the components and their connection options. For example, a cooler with a rotational speed meter can be connected to both the motherboard and the power supply unit (PSU). Otherwise, the speed cannot be measured.

2.1. Open Hardware Monitor

The most convenient utility for determining the temperature of computer components - Open Hardware Monitor ... It is able to detect a variety of sensors, can show the temperature of the "hardware" of the computer, voltage and frequency.

You can download the program for free from its home page.

2.2. Temperature measurement errors

The sensors in the computer are not calibrated. Accordingly, the error between temperatures can be several degrees. For example, a video card heats up to sixty degrees, but the maximum indicator for it is seventy. Games start to slow down only after a while. Therefore, the sensor does not display the actual temperature, and there is overheating.

2.3. How to check CPU temperature

Temperature sensors can be located in different ways. Their location is related to the processor model. For example processor Intel Core i7-2600K has four physical cores, so there are five temperature meters: one for each core and motherboard.

To find out the temperature of the processor, look at the paragraph CPU Core , if he is. To identify overheating, you should load the processor with a serious task and check the temperature in the load. For this, new games are optimal. Play for half an hour and then watch the Max column in the program. To determine the maximum temperature of your processor, look for information in Yandex or another search engine. If you don't know what processor you have, the program shows the model next to the processor icon.

2.4. How to check the temperature of a video card

The temperature of the elements of the video card can be different, depending on the load. Measurement of the maximum temperature will help determine overheating. Therefore, the video card must be loaded. An easy way is to run the game and the program at the same time Open Hardware Monitor ... In the Max column you can see the maximum temperature.

And in some cases this is a lot. In the manual for the motherboard, you can find information about the maximum allowable temperature for the chipset.

2.6. How to check the temperature of the power supply

In the power supply, sensors can only be used to check the fan speed, so that it does not make noise without load. Therefore, you cannot programmatically measure the temperature of the power supply. You should touch the case of the system unit with your hands. If it is hot or smells like burning, burnt plastic, this is overheating.

3. What to do in case of overheating

If you overheat, you need to change the thermal paste and clean the computer from dust. This must be done correctly. If you do not have relevant experience, it is recommended to use the services of a service center. Laptop under warranty will be cleaned from dust in an authorized center free of charge. If there is no service center, you can return it back to the store with a complaint about overheating. In this case, they will perform the cleaning themselves. It is advisable to copy all the data from the laptop, since in service center can do formatting hard disk... In addition, document the transfer of the laptop for diagnostics.

With a desktop computer, everything is the same. The overheating problem should be dealt with by the store where the system unit was sold to you. Whether there is dust or not, overheating must be removed to avoid breakage. In addition, you can clean the computer yourself, but without the appropriate knowledge and care, there is a high probability of breaking something.

3.1. Self-cleaning computer

If you are poorly versed in the location of computer parts, you should not disassemble it yourself. If you find a malfunction, you still have to carry it to a service center.

If you are removing the cooler, then be sure to apply thermal paste between the processor and the heatsink. You can use a cheap KPT-8, which is sold in any specialty store. You should not collect and reuse the paste that was, firstly, over time it loses its properties to efficiently conduct heat, and secondly, when removing the cooler, dust falls on the paste. Therefore, you will have to spread a new one. The layer should be thin, not flowing beyond the surface of the cover and processor. Lack of paste will not allow high-quality heat dissipation.

Instead of thermal paste, developers can use thermal rubber bands. In some cases, they are much more effective, for example, if the distance between two elements is more than a millimeter, the parts cannot fit snugly against each other. This is especially common in laptops.

To cool the hard drive, you can place a fan on the front of the system unit, usually there are brackets for this. Vacuuming computers and laptops is not advisable. One of the reasons is inefficiency. Also, due to the strong air flow, dust gets into hard-to-reach places and it will be impossible to get it.

4. About fans and coolers

A cooler is a symbiosis of a radiator and a fan. This device removes heat with greater efficiency. Its location is video cards, processors, motherboard chipset. Conventional fans (without a heatsink) are located in the chassis and power supply. Since a stream of air is enough for certain components for cooling.

Cooling can also be passive - only the radiator works, the heat from which is removed due to the movement of air inside the system unit. This is often used on low-power video cards. Modern motherboards also only have passive cooling. But it is useless if there is no air movement inside the computer case. Therefore, with passive cooling, at least two fans must be installed in the case - one for blowing out, the other for blowing.

Good cooling and a high-quality sufficient power supply unit, in my opinion, are the main components of a stable computer. We can make the right conclusion - if the computer began to work unstable. then either a problem with the power supply, or overheating.

To avoid problems with the power supply, read this article - well, here we have about overheating of various computer components.

The main symptoms of processor overheating:

1. After the computer boots up, it freezes in 2-5-10 minutes.
2. Unreasonable BSOD (blue screen). Unreasonable - everything worked stably, new programs or equipment were not installed, etc.

3. The computer began to load longer, and it works noticeably slower, especially if you run resource-intensive applications.

The main symptoms of video card overheating:

1. During the game, the computer freezes, and some games may work fine, and some may freeze.
2. Artifacts appear on the monitor, various image distortions, vertical or horizontal stripes etc.

Less often the north or south bridges on motherboards and hard drives overheat, the symptoms are the same - freezes.

How to determine which component is overheating?

Determine processor overheating:

Immediately after turning on the computer, most modern BIOS versions have a tab H / W Monitor (Hardware Monitor), it displays the current temperature of the processor and motherboard, the level of supply voltages, fan speed and other information. If the processor temperature is 70-75 degrees and higher, then this can be definitely defined as overheating, 50-60 degrees for some processors is a normal temperature at rest, but for most processors, the temperature at rest should be below 50 degrees, optimally in the range of 40-50.

If there is no data on the CPU temperature in the BIOS, then you need to install any utility for monitoring the temperature of the PC, for example speedfan.

If the computer freezes so quickly that you do not have time to install anything, then you will have to climb inside the system unit, more on that below.

Determine the overheating of the video card:

If you have checked and determined that the processor does not overheat, and the computer still freezes, the next candidate for checking is a video card or motherboard.

Using utilities to determine the overheating of a video card is more difficult, because not all video cards provide such an opportunity, but you can try to nvidia video cards there is an excellent utility that shows the temperature as well - NVIDIA Inspector, download ATI Tray Tools for ATI video cards, in general you need to search and try.

If the installation of the utilities is impossible, or they do not show the temperature, then you will have to open the system unit and check the temperature of the radiators with your fingers.

The actions described below may void the warranty and damage the equipment!

1. Immediately after freezing, disconnect the computer. (there is usually a small switch on the back of the system unit)
2. Remove the side of the system unit (if you look from the back of the system unit, it will be the right side)
3. With your finger, in turn, touch all the radiators available there, they should be warm or slightly warm, if you cannot hold your finger on some of them, then it is the culprit of overheating.

If the culprit is found out, read - if not - write in the comments, we will search together.

Our today's article will touch upon one of the most common "computer diseases" - processor overheating.

Firstly, I want to say: if the processor heats up, this is normal, since an electric voltage is supplied to it. But if it overheats, this is no longer good and must be fought with.

Secondly: modern chips (from AMD or Intel - not so important), as well as motherboards, have a built-in overheating warning system and forced shutdown if it is detected. So overheating of the processor and its failure is not as relevant now as it used to be.

How can you control the CPU temperature? First of all, these are the "bios" indicators. Depending on its model and implementation, the parameter we need can be located in different sections of the BIOS. Most often it is located in the “Hardware” or “Power” sections and is called “Hardware monitor” (monitoring).

In the figure above, we see the temperature indicators of the processor (CPU Temperature) and - motherboard (MB Temperature). Temperatures are reported in degrees Celsius (C) and Faringates (F).

Here, for example, what an external thermal sensor looked like for taking temperature readings from old ones aMD processors (now such sensors are built into its very core):

To measure temperature, there are also various system utilities, of which there are a great many, but you need to understand that all programs use the readings of hardware sensors-microcircuits located on the computer motherboard.

Previously, monitoring functions were performed by specialized thermal and electrical sensors. Now special microcircuits "Super Multi IO" are engaged in this. They are also called multicontrollers (or - "cartoons"), since they not only take and process all kinds of indicators from tracking sensors, but also control the fan speed, implement the functions of parallel and serial ports, contain mouse and keyboard controllers, FDD, game port, etc.

We can see an example of one such "cartoon" in the photo below. As you can see, the multicontroller is based on the Winbond W83627THF chip.

Note: the normal temperature of a working processor should be in the range from 30 to 60 degrees Celsius (depending on its model), the chipset - from 25 to 50, and the graphics core (video card) - from 40 to 70 degrees. Naturally, depending on the load on a particular component!

And now I want to give one example from practice, when the temperature readings of the BIOS helped me detect overheating of the processor.

In one of my previous jobs, I changed a burned-out motherboard on a computer. Naturally - I removed the processor with the cooling system and installed a new one. Collected, unscrewed, launched - everything works. After about a week, they ask me to come up to see: the computer buzzes a lot, which prevents the accountant working behind it from self-realization :)

I come and hear the fan howl from the doorway. At first, I confess, I thought it was a power supply (this happens to them), but it turned out that the cooling cooler was noisy (a processor was installed under the LGA 775 socket).

I decided to look at the temperature readings of the motherboard and the core in the BIOS, and I was surprised that the sensor showed 85 degrees Celsius. Now, at least, it was clear why the fan worked at maximum speed (the motherboard or the "stone" itself, having detected overheating, raised its rotation speed).

Another thing is noteworthy here - in the conditions of weekly operation in such a temperature regime, no consequences of such overheating were found, leading, as a rule, to reboots and "freezing".

By the way, the reason that overheating took place was one of the cooling system clamps that I did not fully press to the end. As a result, the heatsink did not fit snugly against the protective cover of the processor and could not effectively “take” heat from it. After fixing the problem, the temperature readings were fixed at "59" degrees.

I must say that signs of processor overheating on new computers may not appear even if the active cooling system is forcibly turned off (by pulling the fan power out of the motherboard). If you do not run at the same time sufficiently "heavy" applications (computer games), such systems can function stably for a long time.

I remember another case in our IT department: they brought an old Athlon with symptoms of periodic "freezing" and unstable work software... Asked to reinstall Windows.

Intuitively realizing that the reason was not Windows, we opened the case and found that the heatsink fins of the processor cooling system were so densely clogged with caked dust that it formed a kind of "shield", which, in fact, isolated the heatsink from the fan, which was unsuccessfully trying to dissipate the emission. the core is warm.

I had to remove the entire structure, use a screwdriver to clean the radiator from dust, apply new thermal paste and put everything back together. After that, the computer started working stably and the question about reinstalling Windows dropped automatically :)

What do I want you to understand? That attention should be paid to overheating of the processor (like any other component of the PC).

How to avoid CPU overheating? When installing (or replacing) a radiator, be sure to use thermal grease. Carefully remove the old one and apply a new one to its upper protective cover in an even thin layer, as shown in the photo below:

You can evenly distribute the paste over the surface with your finger (as shown in the photo). I personally use an old, non-working credit card. Its hard plastic allows you to achieve an even distribution of thermal paste over the surface.

I use Zalman paste. It is sold in special bottles and comes with a brush for easy application.

Why do you need thermal paste at all? It plays a very important role in preventing CPU overheating! To efficiently remove heat from the hot core, the lower surface of the heatsink must adhere very tightly to its protective cover (in older models, directly to the processor chip).

The fasteners provide a proper degree of fit, but the problem is that no matter how good the fasteners are and no matter how well the bottom surface of the heatsink is polished, there are still micro-scratches and micro-gaps between the processor and its cooling system.

These very "gaps" are intended to be filled with high-quality thermal paste. Since it is thermally conductive, it significantly increases the overall cooling efficiency by collecting heat from the entire surface and transferring it to the radiator, from which the heat is blown away by the fan.

There are also funny cases: one PC came to us for repair / maintenance. The diagnosis is overheating, the consequence is spontaneous shutdown (overheating protection is triggered). We finished it off and decided to change the thermal paste on the processor. Imagine my surprise when, after removing the old paste under it, I found this picture:

The computer came to us from China (along with a set of measuring equipment), but why weren't the stickers removed when the computer was being assembled ?! To everything else, a transparent polyethylene blotch was neatly glued to the oval! What do you think, what coefficient of thermal conductivity have such "nice" additions? :) The processor heated up to 76 degrees Celsius!

With the help of a clerical knife, alcohol and such a mother, they removed this disgrace, applied a new thermal paste and the heating temperature, as a result, was 61 degrees.

Personally, in order to eliminate the problem of overheating, I used in my home computer a tower-type copper tube radiator. Copper (as opposed to aluminum) conducts heat better, and the general design of "tower" cooling systems makes it much more efficient to deal with the problem of processor overheating.

This is what my Scythe Katana3 looks like.

I would also like to draw your attention to the fact that good (high-quality) fans have three or even four wires for connection. Additional wires allow you to programmatically control the speed of their revolutions and adjust the step of this rotation.

For example, here's what the packaging of my recently purchased 8cm LED fan looks like:

Let's go through the main designations:

RPM - "Rounds Per Minute" number of revolutions per minute
Voltage - supply voltage of the device
Current - consumed current (in Amperes)
Air Flow - air flow generated by the cooler
Noise - emitted noise

All the main parameters related to temperature, rotation speed and voltage can be measured with the wonderful Speed \u200b\u200bFan software, which I always use. This program receives readings from the multicontroller (we talked about it above), which, in turn, takes data from various chips of counters and sensors located on the motherboard.

I can’t resist, and I’ll also dwell on the products of the company "Zalman", I really like them! :) In general, Zalman in computer cooling systems is the same as Intel in the production of processors (a respected and very respectable brand).

For example, here's what their packaged cooling looks like, designed to prevent processor overheating:

The delivery set includes a set for fastening to different boards. Moreover, the fasteners are so versatile that it allows you to install the structure on whole line processor sockets (connectors). Notably, both Intel and AMD CPUs are supported!

Here are the additional accessories for the cooling system itself:

A little more detail:

(1 and 2) - fasteners
3 - "backplate" (The lower part of the cooling mount. Located on the back of the motherboard)
4 - fan speed controller on the processor (displayed on the front or rear panel of the case) Scientific name - "reobass"
5 - power supply cables

Look at the radiator itself. I’m holding the same thing! :)

Massive yet elegant design:

So - do not skimp on the cooling system: overheating of the processor has not brought anyone to any good. And your system unit will look gorgeous after installing such a "toy"! :)

Let's say a few words about the general (classical) organization of the cooling system inside the computer case. It can be described as follows: a fan is placed on the front wall of the case (under the front decorative panel), which blows air into the system unit. Another fan is attached to the rear wall of the case, but it works to blow air out.

In a closed case, such a bundle provides a fairly substantial thrust. Inside, it looks like a large turbine starts working: cool air from the room gets inside and, passing through the entire "stuffing" of the computer, is thrown out.

There is another (not traditional) cooling scheme: in a closed system unit many fans are installed, which all work to blow air inside. During operation, they create excess pressure inside the body, under the influence of which hot air is literally "squeezed" out of numerous holes in the casing.

Here, for example, what a typical laptop cooling system looks like, which also needs to be periodically cleaned of dust:

On this note, we end our material on processor overheating, we hope that our tips and tricks will be useful to you. Looking forward to your feedback and comments!
