What should the processor temperature be? Permissible temperature of the NVIDIA video card. What should the processor temperature be?

If your laptop just turns off, freezes, or just sometimes lags in games, then this article is for you. This article describes how to determine whether a laptop is overheating, as well as how to deal with overheating.

Introduction

IN this manual Let's talk about overheating. In fact, this is one of the most common problems, which are found on laptops. The topic of overheating was partially raised in the article: . In this article I will try to reveal it more fully.

Let's first look at why the laptop overheats. There may be several reasons for this:

1. The cooling system is poorly designed. I think it’s no secret to anyone that laptops are all different. Therefore, they have different systems cooling. For some, it is thought out very well and with a reserve, while others do not have laptops. As a result, some laptops heat up weakly, while others heat up more;
2. Accumulation of dust and other debris in the cooling system. This happens very often. Dust gets clogged in front of the radiator on the fan side. In particularly advanced cases, the thickness of the layer of dust, wool and other debris reaches 5-10 mm. Naturally, the efficiency of the cooling system in this case tends to zero. So the laptop overheats;
3. Loss of contact between the chip surface and the heat sink plate. This also happens. Since then, the thermal paste, which is located between the chip and the plate, has hardened. This can lead not only to a deterioration of its properties, but also to the fact that due to shock or strong vibration, the heat sink plate will simply move away from the layer of hardened thermal paste and an air gap will form. This greatly complicates heat transfer and, as a result, the chip overheats;
4. Incorrect operation of the laptop. Many laptops are designed in such a way that air is drawn in to cool the internal components through holes in the bottom and/or from the keyboard side. If you place the laptop on a soft surface, the holes on the bottom will block. As a result, the laptop will simply overheat. The same applies to working with the lid closed. Some of the holes are blocked, less air enters the cooling system and the laptop overheats.

Let us now consider how overheating usually manifests itself.

Typical symptoms of an overheating laptop:

1. The laptop turns off by itself;
2. The laptop freezes;
3. Games experience occasional stuttering. They are described in more detail in this guide: .

This happens because the overheating protection is triggered. The fact is that modern processors, video cards and chipsets have thermal sensors that constantly monitor the temperature. If the temperature exceeds a certain threshold, the processor and video card reduce their frequency and supply voltage. As a result, the temperature and performance drop and the laptop begins to slow down. Also, if the laptop overheats, it may freeze or turn off. When the video card overheats, extra lines, squares and other defects may appear on the screen. When the processor overheats, the laptop freezes and turns off with a characteristic sound jam.

It is quite logical that in order to determine whether a laptop is overheating or not, you simply need to measure the maximum temperature of the processor, video card and other components. This is what we will do now.

Temperature measurement

The utility is great for measuring laptop temperatures HWMonitor. You can download it using these links: /.

This utility shows the current, minimum and maximum temperatures since startup. We are only interested in maximum temperature values.

Now we launch a game or other application that heavily loads the laptop. We work or play for 15 minutes and see what the utility shows HWMonitor:

Important Note:The HWMonitor utility must be minimized while playing or working with an application. If you start it after you have worked or played, or while you have closed the game, then you will not get accurate data on the maximum temperature. This is due to the fact that if you remove the load, the processor and video card drop their temperature very quickly.

Now I’ll explain what is what:

1. THRM- this is a chipset. During the game he was able to warm up to 74 degrees (right column);
2. Core #0 And Core #1- These are the processor cores. They warmed up to 71 and 72 degrees;
3. GPU Core- this is the video card chip. He was able to warm up to 87 degrees;
4. HDD- this is a hard drive. It heated up to 47 degrees.

Note: if you can’t figure out what the HWMonitor utility is showing you and how bad it is, then don’t be shy and ask in the appropriate forum topic: . To message Necessarily add a window image HWMonitor.

What temperatures are normal:

1. For a processor, the normal temperature can be considered 75-80 degrees under load. If it’s above 90, it’s definitely overheating;
2. For a video card, the normal temperature is 70-90 degrees;
3. For a hard drive, the normal temperature is up to 50-55. If it is above 60, then it is worth copying important data from the hard drive. There is a risk of losing them;
4. For chipset normal temperature up to 90 degrees.

Important Note: Maximum temperatures may vary from model to model. For example, for an nVidia GeForce 8600M GT video card, the normal temperature is 90-95 degrees. For nVidia GeForce 9500M GS - 80-85.

If your laptop does not overheat and the temperatures are significantly lower than those described above, then the cause of freezes, slowdowns and shutdowns should be sought in operating system and drivers. First of all, you need to try updating Laptop BIOS. It is available on your laptop manufacturer's website. If this does not help, then you should reinstall the system, try other drivers, update programs and look at the recommendations from the manual:. If this does not help, then you should contact service center since the cause of laptop freezes and shutdowns may be partial failures of the motherboard (power stabilization circuits and other things). It is very difficult to fix this at home.

If the laptop still overheats, then you need to take measures to cool it.

There are the following basic ways to lower the temperature of a laptop:

1. Put something under rear end;
2. Use a cooling pad;
3. Clean the cooling system from dust;
4. Replacing thermal paste.

Let's look at each of these methods.

1. Raising the rear end of the laptop

In most cases, the air that cools the laptop components is drawn through holes and slots in the bottom of the laptop. Some air is also sucked in from the keyboard. By lifting the back end of the laptop, we increase the gap between the bottom and the table. As a result, air circulation improves. In other words, the air that is forced through the radiator of the cooling system becomes colder. Also, by reducing the resistance of this air, more air is sucked in. As a result Maximum temperature may drop by 5-10 degrees.

You can put anything under the back end, from books to rubber bands. This is what it looks like:

There is nothing complicated. Everything is simple and clear.

2. Using a cooling pad

This method is also quite simple and effective. The bottom line is that the laptop is placed on a stand with fans. These fans force air onto the bottom of the laptop. Air enters through slits and holes in the bottom. As a result, the air flow increases, which blows over the internal components of the laptop and the radiator. In practice, the temperature drops by 5-15 degrees.

This is what the cooling pads look like:

They usually cost from 20-30 to 50-60 $. You can also do this yourself. The stands are usually powered from the laptop's USB port.

3. Cleaning the laptop cooling system from dust

Cleaning the cooling system from dust makes sense if 2-3 months have passed since the purchase. This period depends on the operating conditions of the laptop. After cleaning, the laptop will heat up the same way as after purchase.

This is a service operation and is often not covered by warranty. If possible, entrust this operation to a service center. Behind small fee Everything will be cleaned for you.

If you don’t want to give the laptop to a service center, then you can completely clean it yourself. To do this, you need to partially disassemble the laptop. Cleaning with a vacuum cleaner often does not have a serious effect.

So. Let's begin. First you need to turn off the laptop, unplug it and turn it over:

Before disassembling your laptop, you should remove the battery. This is a must!. When the battery is removed, it is worth analyzing how to get to the fan. On Acer Aspire 5920, for example, to do this you need to remove the large bottom cover. It is held on by the following bolts:

When all the bolts that hold the cover are unscrewed, we begin to remove it a little at a time:

Important Note: Often, in addition to bolts, the lid is held in place by the following latches:

They must be handled very carefully so as not to break. They usually serve to more securely fix the lid.

And here is the fan and radiator that need to be cleaned:

Now you can clean both the blades and the radiator itself:

Since I clean it regularly, there is not a lot of dust and other debris there. In practice, there are cases when a thick layer of debris accumulates in front of the radiator. It is not surprising that the cooling system does not cope with its task and the laptop overheats.

You need to clean it with a dry cloth, napkin or brush.

When we're done cleaning, we put everything back together.

4. Replacing thermal paste in a laptop

This is the most the hard way laptop cooling. Replacing thermal paste requires experience and knowledge. In this case the warranty is void. If possible, entrust this operation to a service center.

The essence of this method is that laptop manufacturers usually use thick layers of thermal paste, which is not the most best characteristics. This is necessary to ensure an acceptable defect rate. If you replace that thermal paste with a more efficient one, you can lower the temperature of the processor and video card by 5-15 degrees.

More details about replacing thermal paste in a laptop are described in this material: Replacing thermal paste in a laptop.

That's all.

If you have questions about this material, you should first read it and then ask on the forum.

The processor is usually called the electronic unit or a microprocessor that executes program code (machine instructions). This is one of the most important parts of any computer or laptop, since the speed of the device also depends on the processor.

This is confirmed by the prices. For example, inexpensive processor will cost you 3-4 thousand rubles, you can find it even cheaper. But really good processors, which will last for many years to come, cost several times more. Currently the market leaders are Intel (Intel Core i3, Intel Core i5, Intel Core i7) and AMD (AMD Athlon).

The processor temperature is determined by its load, that is, the number of processes it runs. It also depends on where the temperature sensor is located. In addition, you need to focus on the generation of the processor that is installed in your computer or laptop. The fact is that with each generation, processors heat up less and less due to their improvement, while models of previous generations can heat up much more.

Now as for the temperature itself.

• When idle, the normal processor temperature is 40-45°C. What does idle mean? This means when the computer is running, but no program is running on it. For example, you turned on your PC and are not doing anything with it. Well, or turned on music using the player. In this state, there is no need to worry about the processor.

• The operating temperature for the processor is 50-60°C. In fact, it is highly desirable that it does not cross the 50°C mark, but even 60°C should not be considered a critical figure. However, if the processor temperature rises to 60°C, it is worth taking care to reduce it.

• If we talk about the maximum operating temperature, you should go to the manufacturer’s website - find your processor model there and see the maximum possible operating temperature. But remember that if it is, say, 90°C, this does not mean that you can not worry about your processor. On the contrary, this is a reason to panic - at this temperature the system will begin to slow down, the computer will reboot, and after a while the processor may.

How to view the processor temperature?

One option is to use BIOS. This method is interesting because you do not need an Internet connection. But if you look from the other side, this method will not help most users. Why? In order to do this, you need to restart the computer. Accordingly, at startup the processor will not be under load and real temperature there's no way to find out. Therefore, I recommend using third-party software.

CPU-Z. It's free application program to display technical information O personal computer user running under OS Microsoft Windows beginning with Windows versions 98 (including Windows 8.1). Available special version for Android. In particular, the program determines specifications central processor, video card, motherboard and random access memory. Popular among IT specialists, computer technicians and repairmen, gamers and overclockers.

SpeedFan. Free utility, which allows you to control the temperature and fan speeds in the system. The program works with almost all monitoring chips, and also allows you to dynamically change fan speeds depending on the temperature inside the computer case. It is possible to change frequencies system bus on some motherboards equipped with frequency generators supported by the program. It keeps statistics of the measured parameters and writes them to a log file; it can also display graphs of changes in temperatures, voltages and fan speeds.

Core Temp . Compact program without unnecessary functions, designed to monitor processor temperature. Core Temp can show the temperature of each individual core in each processor present in the system. Using this utility, you can observe in real time how the temperature of the processor core changes depending on the load. The program supports the entire series Intel processors Core and Core 2 and all processors AMD in the AMD64 line. Core Temp allows you to record changes in processor temperature over time and then transfer the data to Excel.

I think these three utilities will be enough for you (and in fact, one will be enough). There are others, no less interesting programs, for example, the same Everest, but let's not forget that Everest costs money, and the utilities presented above are free.

How to lower the processor temperature?

Finally, I’ll tell you a little about how to lower the processor temperature.

Most main reason Increased temperature of components is caused by dust accumulating inside the system unit. In fact, it should be cleaned at least once every few months, but few people do this. It is mainly necessary to clean the radiator and the cooler itself. To do this, use the simplest brush. Of course, the procedure is carried out with the computer completely turned off, including from the network. Remains of dust in system unit You can collect it with a vacuum cleaner, but you shouldn’t touch the boards with it.

It is possible that what is located between the processor and the cooler is not doing its job. It needs to be replaced. This is not difficult to do, but you will have to purchase thermal paste, which, in fact, allows you to remove heat from the processor.

Perhaps the system unit itself is located next to the battery or in a corner where it cannot be fully cooled. Try moving it to another location.

Alternatively, the cooling system cannot cope with the heat. In this case, it must be replaced with a more efficient one.

CPU overheating! Temperature increase! Heat dissipation! With these words, many scary stories begin about too hot relationships between a person and a laptop. In some of them, the laptop explodes, in some it dies too early... And there are also those where the owner, holding a hot laptop on his lap, can no longer continue the family line.

The key element in all these stories is the processor temperature. It's no secret that while doing its job of processing information, the processor generates heat. Of course, laptops have a cooling system, but its power is not always enough to cool the processor to an acceptable temperature. So, what processor temperature is considered normal for a laptop and how not to go beyond it?

A little theory

Modern processors are initially able to withstand quite a lot of heat without harm. Thus, the critical temperature can reach one hundred degrees Celsius or even more. It’s not just that enthusiastic overclockers come up with special systems cooling to push processors to the limit!

Another thing is that such heat can damage other components of the laptop - for example, plastic elements. The body is unlikely to catch fire, but it is quite likely to melt. This is precisely what is avoided by installing powerful laptops clever heat sinks.

As for the human body, heating to 40-45°C will already cause discomfort for the user, especially if the laptop case is made of metal and conducts heat well. What can we say about higher temperatures!

Of course, low-power processors have much lower heat dissipation, so we will consider only relatively powerful devices based on Intel i5, i7 and AMD FX processors.

On practice

To look at the practical heat dissipation of processors, the researchers looked at several popular models with various processors, both with a discrete video card (which takes on part of the processor load) and with an integrated video core.

Yes, for Acer laptop TravelMate P238-M-5575 with the common dual-core Intel Core i5-6200U processor and built-in video core regular working temperature was about 35-40 degrees. In this range, heating can be noticeable, but does not cause harm to either the device or the person. Using the HW Monitor test utility, we were able to increase the processor load to a level at which the temperature for the complex of both cores was 79°C. This is far from the critical temperature of the processor itself (it is about 100°C), but the user may find it, to put it mildly, elevated. Another thing is that a person will not feel this temperature, since the cooling system in the laptop does its job.

Another model - Asus F555UB-XO043T - is based on the same processor and also does not have a discrete graphics card. The result turned out to be a little predictable: the emitted temperature also remained within 80°C and could not somehow get closer to risky values. The user, of course, should not hold a laptop operating in this mode on his lap, but if the device is on a table (and even more so on a special cooling stand), there should be no harm from this.

Of greater interest to us is testing Gigabyte laptop P55K v5, which belongs to the class of gaming machines and offers maximum hardware. In our case, this is an almost uncompromising Intel Core i7-6700HQ processor (the HQ index means four cores, but overclocking is disabled) plus a video card NVIDIA GeForce GTX 965M. This is a much more powerful kit: although the card reduces the load on the processor itself, it itself contributes to the overall heating. Therefore, the laptop has a more advanced cooling system.

Here tests show numbers that can take your breath away. When running our friend HW Monitor, one of the processor cores heated up to critically close to 99°C, the rest, however, were not too far behind. The heating of the video card reached 81°C.

Dangerous? Yes. But this is an artificially achieved load. In fact, the normal temperature of a laptop processor, even at startup, is very hard games barely reached 80°C. And given that the generated heat is immediately dissipated and removed, the laptop is ready for short-term extreme loads.

Finally, let's dilute the monopoly Intel laptop on AMD processor FX-8800P. This is an Acer Aspire E5-552G, which also has on board AMD video card Radeon R8 M365DX. It is curious that the integration of a system from one manufacturer allows you to use the built-in and discrete video card either alternately or simultaneously in CrossFire mode. This means maximum use of all computing elements, which means maximum heat dissipation.

Let us remind you that for the AMD FX-8800P the critical temperature threshold is lower than for Intel designs, and is only 90°C. For the user, this means that the developers have reduced heat transfer, and the case will not be such a fire-breathing “stove” even under high load.

The results turned out to be very encouraging. Even at the highest voltage provided by the Prime95 utility, the processor temperature only rose to 54°C. The main “stove” (unlike previous examples) suddenly turned out to be discrete video card, which reached as much as 74°C. However, this result is far from critical values.

Practical conclusions

In practice, for users, this experiment can generate a whole set of interesting conclusions:

• If you know what the processor temperature on a laptop should be in theory, then values ​​that seem critical may turn out to be quite acceptable. The numbers may look dangerous, but they are worth comparing with the limit values ​​​​from the processor specifications.
• Laptop developers envision reliable operation of laptop processors within the specified values ​​​​from processor manufacturers.
• But the critical values ​​themselves may decrease if bad work cooling systems. Therefore, owners of powerful gaming laptops should especially carefully monitor the ventilation and heat dissipation of their machines.
• If you frequently use your laptop in extreme mode, it is worth increasing the cooling, for example, with a stand with a fan.
• Case overheating usually does not reach dangerous levels. However, if the case begins to heat up more than usual, this is a signal of a cooling problem. In this case, the following procedures are needed:

1. Update BIOS. If the problem is common to the series, an update may solve it.
2. Replace thermal paste.
3. Check the system for presence malware. You're not interested in someone mining bitcoins on your expensive laptop, wearing it out and giving nothing in return?
4. Be vigilant!

What is one of the most common reasons unstable work computer? Banal overheating. Interruptions, errors, lags, sudden reboots and shutdowns - here incomplete list symptoms that it manifests itself. Is it possible to work comfortably? Of course no. Is it possible to identify the problem before it takes such obvious forms? Absolutely yes. How? It is enough to monitor the temperature of devices from time to time, and the most indicative of them is the temperature of the processor (CPU).

What CPU temperature is considered normal?

To monitor any indicator, you need to know its normal value. Unfortunately, there is no uniform temperature standard for PC and laptop processors. For different generations, modifications and models, it is its own. Thus, the maximum and operating temperatures of mobile CPUs are on average 10-20 degrees higher than desktop ones. Older generation processors can only withstand temperatures up to 60-70 °C, while modern ones can heat up to hundreds and above. AMD products generally have a narrower operating temperature range than Intel.

You can find out what temperature maximum your processor is designed for from its documentation on the manufacturer’s website. Let's look at a couple of examples: Intel® Core™ i5-6200U for laptops and AMD 10 PRO-7850B for desktop systems.

The maximum temperature of the Intel Core i5 6200U chip is indicated in the case specifications (the “T junction” parameter). As we can see, it is 100 °C.

If mobile processor produced in two buildings different types- removable and non-removable, the “T junction” column contains 2 values. Intel Core i5 6200U is available only in a non-removable case - FC BGA 1356, as indicated by the letters BGA ( B all G rid A rray) in its name. The pins of microcircuits in such packages are an array of tiny balls that are soldered to contact pads on motherboard.

The name of Intel removable processors contains the abbreviation PGA ( P in G rid A ray). Their contacts are represented by an array of pins that are inserted into the socket (processor socket).

The maximum temperature of modern mobile CPUs in BGA modifications is 100-105 °C, and PGA - 80-90 °C.

The maximum temperature limit for this CPU is 72.4°C. This is the average value for AMD A-series desktop gems.

The optimal temperature value for both mobile and desktop processors is conventionally considered to be 35-50% below the maximum under normal load. Short-term peak rises to values ​​10-15% below the limit are also considered acceptable.

Why is overheating harmful to your computer?

Some users are very frightened by even a slight increase in the temperature of the processor, they say, it can burn out. Not really. Modern CPUs have very reliable system thermal protection and just don’t burn. When the temperature reaches the limit, they reduce clock frequency, which gives them the opportunity to cool a little. At this time, the computer suddenly slows down or freezes completely. And if heating continues and reaches a maximum, it turns off.

The processor temperature is an indicator of the health of the entire system. Her constants high values usually indicate overheating of other devices, which happens, for example, due to contamination of the cooling system with dust. Excessively high temperature environment Most of all, it is harmful not for the processor, but for the mechanics hard drive. But sudden power outages when the CPU thermal protection is triggered are especially dangerous for it. The fact is that the read and write heads, which fly above the surface of the platters during disk operation, may not have time to move to the parking area, fall on the magnetic layer and physically destroy some of the information on it.

High temperatures inside the PC case also have an adverse effect on the condition of the power supply and video card. Both of these devices generate a lot of heat during operation, and constant exposure to sauna conditions contributes to their wear and failure much earlier than expected.

CPU Temperature Monitoring Tools

There are many programs with CPU temperature monitoring functions in nature. The following are the most popular among our compatriots:

• HWiNFO 32/64 — free Windows application, displaying a significant amount of information about all computer devices, including temperature sensor readings.
• Aida64 is a paid utility with a 30-day warranty trial period, which in addition information functions has diagnostic.
• Core Temp is a simple program that shows detailed information about the processor and constantly monitors its temperatures.
• Real Temp - produces almost the same data as Core Temp, plus it has the function sound notification when the specified temperature threshold is reached.

And CPU-Z, unfortunately, does not show the processor temperature.

In the example below - part pivot table system monitoring, obtained by the HWiNFO utility.

The first column of values ​​displays the current CPU status indicators, the second - the minimum, the third - the maximum, the fourth - the average.

Unfortunately, universal utilities of the above do not always provide reliable data. As, for example, in the case shown in the following screenshot.

Here, we see that the first temperature value is much lower than room temperature, and the second is approaching the upper limit of the norm for this processor. To find out what it really is, I'll use Asus utility AI Suite 3, which was installed on the computer along with the motherboard drivers (Windows 7 OS). Her indicator is exactly true. And normal.

By the way, you can find out the temperature of the “stone” without programs. Just look into the BIOS. In console versions BIOS utilities The Setup option is called “CPU temperature” (sometimes “CPU Temp” or “Processor Temp”) and is located in the “Power” or “PC Health” section. IN graphic versions(UEFI) it is usually displayed on the main screen.

BIOS indicators are certainly reliable, but not very informative, since the computer at this time does not perform any operations that load it. After Windows startup The processor temperature rises by about 5-10 °C as they begin to work system processes and background programs.

How to evaluate the efficiency of a cooling system

You can judge whether the cooling system of the processor (and other devices) is functioning effectively enough indirectly - by the operation of the computer. When the equipment is well cooled, the machine operates stably, uninterruptedly and confidently pulls a load adequate for it. Temperature indicators CPUs approach the upper thresholds only when working very intensively, but do not reach the maximum.

If there is insufficient cooling, the computer begins to slow down, first at high, then at medium, and finally at light load. In particularly advanced cases, it freezes during Windows startup or even before it starts. It often reboots and turns off spontaneously. CPU cooler and other fans usually emit a loud howl, and from ventilation holes housings, if they are not completely clogged with dust, hot air is blown out.

There are situations when you need to quickly check the efficiency of the heat dissipation from the processor, for example, if you are overclocking a system or diagnosing someone else's computer. This can be done using any CPU stress testing program that displays real-time temperature graphs. The test takes 5-10 minutes. At this time, you should watch the growth line, numeric values are secondary here.

A CPU temperature rise curve with a gentle rise indicates that the cooling system is effectively coping with its task. And if the line goes up almost immediately, the processor is not cooled enough.

An example of such a test in the AIDA64 program running on Windows 10 is shown in the screenshot below.

In this graph we see completely normal indicators. At 100% load, the laptop CPU heated up from 55 °C to 70-72 °C, and the temperature rise line was almost horizontal. By the way, the “T junction” of this processor is 100 °C, which means it has about 30 degrees in reserve.

How to improve CPU cooling

An increase in CPU temperature above normal is a consequence of two reasons: increased heat generation or decreased cooling efficiency. Heat generation increases as a result of overclocking or replacing the “stone” with a more efficient one, and the cooling system ceases to perform its functions due to contamination or breakdown.

I think it’s clear how to deal with dust pollution on a computer. In short, for prevention it is enough to blow out the cooling system from a can of water once every 2-3 months (more often under circumstances). compressed air(sold in office equipment stores).

In advanced cases, large accumulations of dust are removed with a vacuum cleaner, after which the cooler is dismantled and fresh thermal paste is applied to the processor.

Many owners cope with cleaning system units on their own. The most difficult thing here is to remove and install the cooler correctly without damaging anything. With laptops, things are different: some models are easy to clean - to access the cooling system, you just need to unscrew a few screws and remove the cover, while others are difficult, since they have to be disassembled almost completely.

If your desktop PC's processor overheats because the cooling system can't handle it, you'll most likely have to replace it with a more efficient one.

Choosing a suitable cooler

The same documents where we looked at the maximum permissible temperature will tell you which cooler can effectively cool your processor. Namely, the specifications on the manufacturer’s website. This time we are interested in the following 2 parameters:

• Thermal power (design power or TDP).
• Socket type (processor socket configuration).

Here is an example of these settings for the Intel® Core™ i5-7400:

And here is for AMD Ryzen™ 5 1600:

So to new cooler was able to lower the temperature of the CPU to acceptable values, its TDP - heat dissipation ability, measured in Watts, must be no less than the TDP of the processor. More is possible. Also, the cooler must support the socket configuration, otherwise you will not be able to install it on the board.

Another one important characteristic The thing you should always look at when choosing a cooler is the dimensions. Too large may not fit in the system unit or block 1-2 RAM slots on the motherboard. The remaining parameters are of secondary importance.

Let's try, as an example, to select a cooler for the Intel Core i5-7400 on Yandex Market. If we do not take into account the dimensions, any model with a TDP of 65 W and support will suit us LGA socket 1151.

Let's enter these parameters into the search system and get a list:

• Cooler Master DP6-8E5SB-PL-GP.
• Thermalright Macho Rev.B.
• Zalman CNPS9900DF.
• Deepcool NEPTWIN V2.
• Noctua NH-U14S, etc.

Prices, as you can see, range from 420 to more than five thousand rubles. Of course, the selection also included powerful gaming coolers capable of cooling irons, but for our not too hot CPU, serious expenses are not justified. The model will cope with its cooling for 450-800 rubles. The rest is a matter of taste.
