Monitoring the operation of basic computer systems is a mandatory measure. The most important and loaded part of the system is the central processor - the speed of the operating system depends on the stability of its operating characteristics. High load on the CPU leads to excessive heating or failure. To avoid breakdowns, you should know exactly what temperature conditions will be optimal.
Any chipset is made on the basis of silicon - a good semiconductor, but highly dependent on temperature. The critical temperature for a crystal is a threshold of 150 degrees. Exceeding this threshold leads to irreversible changes in its structure and loss of performance.
The reason for this may be the following factors:
- High CPU load when multiple resource-intensive applications are running.
- Dust in the processor heatsink, which seriously impairs heat transfer.
- High temperature inside the system unit due to a malfunction or contamination of the cooling system.
- Incorrect installation of the processor or an air gap between the cooled surfaces (occurs due to cracking of the thermal paste).
The power of a standard working cooler is sufficient in 90% of cases. Normal temperature indicators for the CPU will be as follows:
- 45-50 0 C – temperature of a computer or laptop running in the background. CPU usage is 1-2%.
- 65-70 0 C is the normal operating temperature for Intel processors. For AMD chips, the upper limit reaches 80 0 C. This is due to the design and architecture features of the processors.
- Above 70-80 degrees is considered critical, in which the processor itself operates at the limit of its capabilities. A further increase will lead to a reboot of the system if an emergency shutdown is triggered, or to its failure.
On a note! Stable - this is a reason to think about the health of the cooling system or replacing it with a more efficient one.
CPU cooling systems
Currently, three types of cooling systems are used.
- Passive. It is a massive aluminum heatsink mounted on top of the processor. Removes all heat due to the large surface area and good thermal conductivity of the metal. Does not require electricity, very reliable and cheap. Works well with low and medium power chips.
- Active. This is a well-known radiator with an air cooler. Thanks to the fan, a large amount of heat is effectively removed. There is only one drawback - it attracts dust well, which reduces the cooling efficiency.
- Liquid. The most expensive and advanced system. Used in extreme gaming work computers. Heat is removed from the processor using liquid and dissipated in radiators outside the case. A special pump is used to pump the coolant.
Ways to find out the temperature
For control, one check per month is enough. All motherboards are equipped with built-in temperature sensors. You can view the data through the BIOS or any specialized program.
To enter the BIOS, press the F2 or Del button, depending on the board model, and select the System Health or CPU Storage tab. In the window that opens, all information about the physical processes inside the computer is visible. Modern systems have a protective reset function when overheating or reaching a user-set temperature.
The second method is to install utilities such as CPU-Z, CPU Thermometer and other similar ones. A special feature of these programs is the possibility of detailed control over all important parameters of the CPU, video card and hard drive. So for the main processor you can get the temperature of each core and its load as a percentage, the temperature of the processor case, fan speed and voltage. Some programs, for example, HWmonitor, keep statistics of parameters during operation.
What to do if the temperature is slightly above the normal range? Most often this happens due to contamination of the cooler. It is easy to clean it at home.
To do this, turn off the power to the computer and open the case. We will see a thick layer of dust on all coolers, which must be carefully removed. It is more convenient to do this with a vacuum cleaner and a brush with soft bristles. Turn on the vacuum cleaner at low suction and carefully remove all the dirt.
It will be much more effective to clean with incomplete disassembly of the system unit and replacement of all processors. Its service life is several years, and over time it loses its heat-conducting properties, which leads to overheating of the CPU. All these measures will help extend the life of your computer for a long time.

Overheating is one of the main reasons why laptops and desktops slow down.
Overheating: symptoms and consequences
The most typical symptoms of overheating computers and laptops:
- Games freeze and crash some time after they are launched.
- Unexpected computer shutdown.
- The computer freezes or turns off some time after turning it on.
The hottest components are the processor, video card, hard drive, power supply and chipset on the motherboard. Let's consider each case separately:
CPU overheating
Symptoms: Program freezes, unexpected reboots, unexpected computer shutdown, and the appearance of a “blue screen of death.”
Consequences: CPU overheating threatens degradation(destruction) of the chip (processor). In this case, the processor may work, but unstablely, with errors, which will cause constant problems. A processor that has undergone degradation cannot be repaired - it will have to be thrown away.
Video card overheating
Symptoms: freezing while playing games and watching videos, rebooting the computer after several minutes of playing, the appearance of a “blue screen of death”, graphic artifacts on the screen (disappearance of textures, the appearance of stripes and dots), disappearance of the image on the monitor both during operation and immediately after turning on computer, the message “The video driver has stopped responding and has been restored” appears.
Consequences: As with the processor, prolonged overheating can cause video card components to degrade.
Hard drive overheating
Symptoms: unexpected computer freeze, clicking sound from the system unit, Windows will not load, read/write errors.
Consequences: Usually, symptoms of an overheated hard drive appear only when overheating has done its dirty work. In this case, if you want to recover data from your hard drive, there is only one way - to the service center. The hard drives themselves cannot be repaired, but there is a chance to “pull” data out of it.
Power supply overheating
Symptoms: burning smell while the computer is running, does not turn on or turns off immediately after turning on, unexpected reboots and shutdowns, freezing while playing games or watching videos.
Consequences: overheating threatens the failure of the power supply components; repairs at a service center are not expensive.
Overheating of the chipset on the motherboard
Symptoms: unexpected disconnection of the keyboard, mouse, USB failure, lost connection to the hard drive, disk drives, computer freezes, spontaneous shutdowns, reboots.
Consequences: like a processor, a chipset (what it is, see Wikipedia) can also degrade. If you don’t keep track of the temperature of the motherboard, you will have to buy a new one, because... repairs are very expensive.
Overheating of other computer components
Various batteries scattered around the motherboard also heat up. In the photo above, radiators are installed on and near them for more efficient cooling. Unfortunately, manufacturers often save money and do not install the required cooling, counting on the fact that the motherboard will only operate in “normal” operating mode (without overclocking the processor), relying on air cooling. Therefore, there is always at least one fan in the case must be installed to cool components through air movement.
Of course, the matter is not limited to all these symptoms. I have listed only the most popular ones.
Why does your computer slow down due to overheating?
The most common symptom of overheating is “brakes” while the computer is running. Usually they do not appear immediately after turning on the computer, but after several minutes or even hours of operation (when the processor heats up to a critical temperature).
At high temperatures, the processor slows down its performance, due to which its temperature decreases or at least does not increase above the permissible limit. This process is called "throttling". The “permissible temperature” of the processor can be anything - 65 degrees, 70, 80, etc., depending on the model.
Throttling works on both modern processors and video cards. Therefore, if games freeze or slow down a few minutes after launch, it is almost certainly overheating.
Why does the computer restart due to overheating?
Windows is a complex software package. If somewhere the processor produces an incorrect result in calculations (and they will certainly be due to overheating), then everything “collapses”. The consequence of such a failure will be BSOD (from the English Blue Screen of Death - “blue screen of death”).
This is a critical error that cannot be ignored. Windows is configured by default to restart the computer if there is a BSOD. Therefore, when the computer overheats, it most often reboots immediately after the blue screen appears. Or it may not reboot, presenting the astonished user with a blue screen with white text.
By the way, Windows 8 draws a sad smiley face on this screen.
You can disable automatic reboot after BSOD like this: Control Panel - System - Advanced system settings - Boot and Recovery - Settings - uncheck "Perform automatic reboot" - OK - OK.
In fact, there are many reasons for the appearance of BSOD - incorrectly working programs and drivers, errors on the hard drive. But now we are interested in it as a symptom of computer overheating.
Why does your computer get hotter over time?
It's all about dust and wear and tear on cooling components. Fans with air suck in dust, which settles on radiators and other computer components. The more dust on the radiators, the more difficult it is to remove heat, the more heating.
The fans themselves wear out over time, which is why they can make noise, spin more slowly, or even stop altogether. Also, over time, the thermal conductivity of the thermal interface - thermal paste or thermal pads, which are needed for high-quality heat transfer from the processor to the radiator - deteriorates. All this requires cleaning and replacement, but more on that later - in the final part of the article.
We measure the temperature
The inside of the computer contains many sensors that measure both the temperature of the components and the voltage and fan speed. The exact number varies depending on the components and their connections. For example, a fan with a rotation speed sensor can be connected both to a motherboard that supports these sensors, and directly to the power supply. In the second case, it will be impossible to measure the speed. And if the motherboard, in principle, does not support a speed sensor, don’t connect it like a cooler, you won’t be able to measure the rotation speed.
Conclusion: the number of sensors depends on the laptop model or the contents of the computer.
Open Hardware Monitor program
In my opinion, the most convenient free program for measuring the temperature of computer components. Capable of identifying a large number of sensors. It can show both the temperature of the computer hardware and the voltage supplied to the components and frequencies.
You can download the program for free from its home page (the size is less than half a megabyte).
About temperature measurement errors
The sensors in the computer are not calibrated. This means that the actual temperature may differ by several degrees. Example: the video card heats up to 60 degrees, but the limit for it is 70. However, games begin to slow down after some time. This means that the sensor clearly does not display the real temperature and overheating occurs.
Checking CPU Temperature
Depending on the processor model, the number and location of temperature sensors may differ.
For example, let's measure the processor temperature Intel Core i7-2600K. This processor has 4 physical cores, so we have 5 temperature sensors: one for each core and the remaining one on the motherboard nearby:
In the screenshot CPU Core- sensors showing the real temperature of the cores, CPU Package- sensor near the processor on the motherboard. Thus, to find out the temperature of the processor, you should look at “CPU Core” (if there is such an item). For the processor from the screenshot above, the maximum permissible temperature is as much as 90 degrees (). However, this temperature is not acceptable for all processors. Sometimes 65 degrees Celsius is the limit after which processor degradation begins.
To detect overheating you need to load the processor with a heavy task and measure the temperature under the load. For example, games will do, preferably newer ones. Play the game for half an hour, then watch the column Max in the program window. To find out the maximum permissible processor temperature, search for information on Google or Yandex specifically for your model: “maximum processor temperature ( processor model)».
For those who don't know what processor is installed in your computer: the model will be written in the Open Hardware Monitor program opposite the green processor icon:
Checking the video card temperature
As with the processor, the temperature of the graphics card components can vary depending on the load. Measurement only maximum temperature will help calculate overheating. Therefore, the video card needs to be loaded with something. The simplest way is to launch any game and play a little (half an hour is usually enough) with the Open Hardware Monitor program running. In a collumn Max The maximum temperature will be recorded:
The screenshot shows that on this computer the temperature of the video card under load did not exceed 53 degrees, which is a very good result. Typically, a video card temperature of up to 60 degrees is considered normal. In certain cases it can even reach 90 degrees, but this moment needs to be clarified, by typing into Google a query like “maximum video card temperature ( video card name)».
It may turn out that it is the overheating of the video card that is the cause of the computer’s brakes and unexpected reboots.
Checking the motherboard temperature
Temperature sensors are displayed in the section dedicated to the motherboard. Here is a screenshot, pay attention to the icon:
Everyone's motherboard is different, the names and number of sensors vary. No sensor should exceed 50 degrees Celsius. Although in some cases 50 is already a lot.
The instructions for the motherboard often indicate the maximum permissible temperatures for the chipset. If you do not have instructions, download them from the official website of the motherboard manufacturer.
Checking the power supply temperature
If there are sensors in the power supply, they are only for automatic control of the fan rotation speed so that it does not make noise without load. Therefore, programmatically measure the temperature of the power supply it is forbidden. You need to touch the body of the system unit with your hands in the area of the power supply - usually from the top back or bottom back. The power supply is connected to a cable from the outlet, so you can’t go wrong with the location. If the case is hot to the touch in this place or there is a smell of burning plastic coming out from there, this is overheating.
What to do if you overheat
There is only one answer: Clean the dust and change the thermal paste!
This matter must be approached wisely. If you do not have experience in this matter, consider contacting a service center:
Laptop with valid warranty: An authorized service center will clean it from dust free of charge (under warranty). If there are no authorized (branded) service centers, you can take it to the store where you purchased it with a complaint about overheating. In this case, the store itself will take care of it, sending it to its service center for diagnostics and (if dust is detected) cleaning. It is advisable to copy all important data from the laptop, because the service center can format the hard drive (of course, this is a “severe” case, but it happens). Also, be sure to document the transfer of the laptop for diagnostics - you cannot return the product to the store without clear documented reasons.
Laptop with expired warranty: Once the warranty has expired, it means your laptop is already more than a year old. Over such a period of time there will be a lot of dust in it. You can take it to any service center for cleaning. The service is relatively inexpensive - the most greedy service center charges no more than a thousand rubles for cleaning a laptop from dust.
With desktop computer under warranty the situation is similar. The store where they sold you the system unit must deal with overheating issues. Whether there is dust in the system unit or not, overheating must be eliminated to avoid damage.
Desktop without warranty(or expired) can also be cleaned for you at the service center. Of course, for money.
You can clean your desktop computer yourself - here are good instructions. However, remember - without proper knowledge and care, there is a high risk of breaking something. There are also good instructions for cleaning laptops from dust. The design of laptops varies from model to model, so most likely you will also have to look for disassembly instructions for your particular laptop model.
These tips are “cries from the soul.” A situation often occurs when a novice user starts cleaning a computer without understanding some of the subtleties. So I advise you to read and gain knowledge:
- If you do not know where each computer component is located, it is better not to disassemble the computer. In the event of a breakdown, you will still have to contact the service center, but you will have to pay not only for cleaning, but also for repairs.
- Carefully read the article about cleaning at the link above, and also look for other articles on the Internet.
- If you want to remove the cooler, you will definitely need to apply thermal paste between the processor and the radiator. Not toothpaste (there are advanced cases), but a thermal interface. You can buy cheap KPT-8, sold in any computer store. And the fan is not lubricated with thermal paste (these are already advanced cases with acute exacerbation). The same applies to the video card, only there it is advisable to use better thermal paste.
- When removing the cooler, there is no point in collecting and reapplying the thermal paste that was there - firstly, over time, the thermal paste loses its ability to effectively conduct heat, and secondly, when removing the cooler, dust falls on the thermal paste, which greatly worsens its thermal conductivity properties. You'll have to apply a new one.
- The layer of thermal paste should be thin and not leak beyond the surface of the processor cover. You can’t apply too much either - if it doesn’t spread over the entire area of the processor cover when it comes into contact with the heatsink, there won’t be high-quality heat dissipation. Understanding how much thermal paste to apply comes with experience. Useful links: one, two, three.
- Instead of thermal paste, manufacturers can use thermal pads (“thermal rubber bands,” as some call them). In some cases, a thermal pad works more effectively than thermal paste - for example, if the distance between the radiator and the processor cover is more than a millimeter, they cannot press against each other. This is a common case in laptops. Useful link.
- To cool the hard drive, you can place a fan of any size in the area of the front panel of the system unit - usually there are mounts there. If not, fans are sold with mounting under the hard drive. Unfortunately, cheap models are noticeably noisy, so they are useful only as a last resort. It is easy to install - the screws are included, the fan is connected to the outputs from the power supply - Molex.
- If the fan is noisy, this can be fixed, but not always. There are many instructions on the Internet for cleaning and lubricating fans.
- Vacuuming computers and laptops is not recommended. Firstly, this is simply ineffective, and secondly, due to the powerful air movement, the dust will get into such hard-to-reach places that you won’t be able to get it out with a brush or cloth.
- I also recommend that you familiarize yourself with this catalog of links: Air cooling (main topics) - a guide.
Useful information about fans and coolers
Cooler- this is a radiator plus a fan. This technical solution removes heat much more efficiently than if only the processor was blown fan. Coolers are usually installed on processors, video cards, and motherboard chipsets.
Fans(without a radiator) are placed in the case and power supplies. Some components simply require air movement to cool, i.e. banal airflow.
Cooling of components can also be passive- only a radiator is installed, the heat from which is lost due to the movement of air inside the system unit. This is a common solution on low-power video cards. Modern motherboards also have only passive cooling on their components.
An important point: passive cooling is useless if there is no air movement inside the computer case. Therefore, with passive cooling, at least a pair of fans - one for injection, the other for exhaust - must be installed in the case.
Of course, the pictures above do not show all possible models of cooling equipment. Human imagination is inexhaustible. There are also cooling using water, oil, liquid nitrogen, etc. All this is covered in the guide to cooling systems, the link to which I have already given above. If there are any points in the article that are unclear to you, write in the comments, I will try to answer and supplement the text.

Today it is difficult to imagine a person who would not have a computer at home. Moreover, we are talking not only about desktops in the classical sense of the word, but also about laptops, tablets and all-in-one computers.
Most often, people are buying laptops lately, since they can serve as an equivalent replacement for bulky desktops. The problem is that many do not have the slightest idea about even the most basic rules for caring for such equipment. Due to ignorance, it often fails.
What can cause a computer to break down?
Do you know how to find out the temperature of a laptop? It would seem, what does temperature have to do with care? Oddly enough, but the most direct. The more the processor heats up, the worse the cooling system works, the higher and higher the likelihood of the laptop failing. It is overheating (after spilled drinks) that takes honorable second place among the causes of “death” of mobile computers.
In some cases, the manufacturer’s engineers are to blame for simply failing to design a normal heat dissipation system, but more often the fault lies with the users themselves, who are trying to run the latest gaming hits on a cheap laptop.
The characteristics of modern processors (the same Core i3) make it possible to do this, but the system is still not able to remove excess heat.
So how to find out the temperature of a laptop? Let's look at a few programs that will help you do this.
Open Hardware Monitor
This is an extremely simple, but quite informative system monitor. The program is completely free and does not require installation. To obtain information about the temperature of your processor, right-click on its “.exe file”, and then select “Run as administrator” from the menu that opens.
A rather ascetic main application window will open, in which the overall system temperature will be recorded in the first two positions, and below will be the readings of the processor, video card and hard drive.
Here's how to find out your laptop's temperature using this utility. But what to do with the resulting numbers? To help you understand, here are the average statistical data on the maximum permissible heating of components:
- central processor - from 70 to 80 degrees Celsius;
- video card (air-cooled) - 80 degrees Celsius maximum;
- the most “gentle” in this regard is the hard drive, which should not heat up above 60 degrees.
However, the latter does not apply to solid-state drives, which are practically not subject to heating.
How can you find out the temperature of a laptop so that the information received is as objective and reliable as possible? To do this, you will have to use the simplest method of “stress” testing.
Let's start the stress test
First, close the windows of third-party programs (including browsers), go to Open Hardware Monitor with administrator rights. If the temperature indicators are far from those given in the article, you can start.
Launch something like a game or a heavy program like Photoshop. In principle, half an hour of work is enough, after which you can start Hardware Monitor again. If the indicators are almost very close to the maximum values given above, then there is something wrong with the cooling system of your laptop.
How can you check the temperature of a laptop using more functional programs? And do such people exist in the world?
AIDA 64
The wonderful application AIDA 64 was developed by Lavalys and was originally known to users under the name Everest. Since checking the temperature of a laptop is often only required once, a month-long trial version will be sufficient for most users.
We think that it is not worth describing the installation in detail, since any user who has at least once dealt with a computer can handle this. This laptop temperature detection program runs with administrator rights, so be sure to confirm the appropriate privileges in the UAC window that appears.
Open the “Computer” tab and look for the “Sensors” item there. Note! The subsequent system scan will take some time, so be patient. The more similar your laptop is to a typewriter, the longer the scan will take.
Explanation of symbols
After this process, a dialog box will appear in front of you, in which the scan results will be presented. Since many of them are presented in the form of symbols, it doesn’t hurt to decipher them:
- The “CPU” designation indicates the temperature of the central processor;
- “GPU Diode” shows the temperature of the GPU on the video card;
- something like: WS Digital HTS725... indicates the temperature of the hard drive;
- CPU1/1, CPU2/2 - show the heating of each processor core (if it is multi-core) separately.
By the way, to what extent do the above indicators correspond to the norm? It should be noted that the maximum allowed often varies greatly depending on the manufacturer, so you should look for exact data on its official website. The same goes for the video card.
Speaking on average, the normal temperature of a laptop should not exceed 45-50 degrees on average. Please note that average computers of this type are not distinguished by brutal performance, and therefore their components most often do not contain particularly powerful parts.
Thus, if your laptop for 13-25 thousand rubles suddenly starts to warm up to 60 degrees Celsius, then this is already a reason to raise the alarm.
Checking laptop temperature without using third-party programs
We don’t always have access to the Internet, and measuring the temperature of a laptop may be required at any time. What to do in this case?
Reboot your computer. At this time, press and hold the button. This action will result in loading not the operating system itself, but the BIOS. Since there are currently dozens of versions of the mentioned software, it is simply impossible to give specific instructions, so let’s talk about the general procedure.
First you should find the “H/W Monitor” item. Go to this line using the arrows on your keyboard, then press Enter. After this, you will see several symbols, with the first number indicating the temperature in Fahrenheit, and the second in Celsius.
In general, the monitor will show something like this: System Temperature 80*F/30*C CPU Temperature 90*F/36*C.
Fan speed
So, we told you how to use a laptop without resorting to the help of any third-party programs. Important! In most cases, the CPU temperature should not exceed 50 degrees Celsius. The only exceptions are single-core processors from AMD of older series, which can become hotter even under normal load.
If you expand the list, you can find out more detailed information about all temperature indicators, as well as the rotation speed of the coolers. This data will be in the function section or in a section with a similar name.
In general, the temperature of the laptop depends on the normal operation of the cooler. The program will only show you general indicators, but you must interpret them yourself. Thus, a low rotation speed of the cooler under heavy loads indicates that its pulley is clogged with dust.
To exit the BIOS, press the ESC button, and then F10. This is where your research ends.
How to know if your laptop is working at its maximum capacity
We talked so much about how to check the temperature of a laptop that we completely forgot to talk about the signs that indicate the need for such a check. It's time to correct this unfortunate omission!
Firstly, you need to pay attention to the condition of the cooling system in case of heating when watching HD movies, playing games and working with photos.
As a rule, the device’s fan begins to howl, the bottom panel of the laptop almost melts, and the keyboard becomes uncomfortable to work on, as it becomes very hot. In this case, there are clear manifestations of overheating, which can also be expressed in a sharp slowdown in the launch of even the simplest applications.
How to prevent overheating?
Having spent so much time talking about what the temperature of a laptop should be and how to determine it, it would be ridiculous not to talk about methods and principles for preventing such a situation. So, what needs to be done to prevent equipment failure due to overheating?
First, clean the external air duct grilles from dust at least once a month. This will ensure that hot air leaves the cooling system without unnecessary effort. Wipe your computer regularly with special cleaning wipes.
Avoid working on your laptop by placing it on a thick, loose blanket. In such conditions, even the most sophisticated cooling system will not cope with its responsibilities. Finally, be sure to change the thermal paste at least once every six months.
Tools
Also, don't forget to buy a can of compressed air: it's extremely convenient to blow out dust, lint, and cat hair from the hardest-to-reach places on your laptop. In addition, it won’t hurt to “walk” through the manufacturer’s official website. There you may find useful tips regarding the repair and prevention of breakdowns of your computer model.
In particular, cooling system diagrams are most often found on official resources. If you decide to disassemble it to replace thermal paste, then these materials will provide you with significant support.
Speaking about the heat-conducting paste itself, we could recommend purchasing it only in specialized computer stores. Moreover, you need to purchase exactly those brands that were recommended by the manufacturer of your laptop.
Finally, soberly assess the capabilities of your own equipment: if your computer is equipped with a weak Celeron processor, its design does not provide for it, then you should not run “heavy” applications. This won't end well.
Temperature analysis is very important because all computer components must operate within a strict temperature range. For example, the heating of the video adapter of a computer with Windows 7 should not exceed 56 degrees Celsius during normal operation, and during computer games this figure is 78 degrees.
If the values are close to or exceed the specified values, then the video card may very soon be damaged. The situation is similar with other computer components.
What causes an increase in computer temperature?
The main influence is exerted by the following circumstances:
- There must be a special thermal paste between the cooling elements (radiators) and the equipment (for example, the processor). Lack of paste, damage or loss of its properties will cause overheating of the equipment.
- Excessive overclocking of the computer, lack of proper application settings, infection with virus programs.
- Finding the PC near heating elements.
- Violation of the ventilation system of the system unit.
- Significant accumulation of contaminants on the cooling elements.
How to find out the temperature without additional programs in Windows 7?
It is required while the computer is booting, by pressing the “Del” button on the keyboard, to enter the “BIOS”. In BIOS, click enter “H/W Monitor”. Temperatures are shown here. First is the indicator in Celsius, and the second is in Fahrenheit. For example, System Temperature, 35 C/95 F, CPU Temperature 31 C/91 F.
If it is above 50 degrees, then you urgently need to find out the reasons; it may be caused by a breakdown of the cooler. Weekly is a must.
Attention: there are different versions of BIOS, so the method of entering it will vary. You need to find out this by studying the documentation of the motherboard, which indicates the method of entering the Bios.
Special applications that allow you to find out the temperature of a computer with Windows 7
There are many programs to find out the temperature of the components of a computer with Windows 7.
CPU Thermometer
A very easy to use and convenient program for monitoring the degree of processor heating - CPU Thermometer 1.2. It does not require installation or special Windows settings. You just need to place the contents of the archive in a folder on your desktop and run the file with the image of the thermometer. Using it, you can find out the temperatures of all processors on a computer running Windows 7. You can view it during further work from the bottom panel, where it appears after startup.
Core Temp
You can also check the temperature of the processor using the Core Temp application. It also allows you to set upper value limits (without Windows intervention) and has a report saving function. The user can perform fault analysis and perform timely diagnostics of the processor. It is recommended that before viewing the temperature, you check your PC for virus infection.
Feature-rich applications
HWMonitor
A small, versatile program, HWMonitor is recommended for advanced users. With it, it is possible to check the entire system. You can see the speed and voltage values supplied to the coolers. The utility allows you to find out the temperature of the video card, hard drives and check the HDD-S.M.A.R.T.
If AIDA64 is already installed on your computer, then immediately proceed to the second step.
- Go to the AIDA64 website https://www.aida64russia.com/.
- Click on the first download button in the list in the form of a down arrow (highlighted in red).
- Then run the downloaded file. After selecting the language, you will see a window like this. Click the “Next” button.
- Then we accept the terms of the license agreement.
- Choose a path to the program that is convenient for installation.
- And install the program.
- After installing the program, leave only the launch checkbox and click the finish button.
- When you launch the program, a message appears stating that you are using a trial version, which will expire in 30 days. It’s okay, it won’t bother you, just click the “OK” button.
Step two. Finding out the processor temperature
What should be the normal temperature of a computer?
The operating temperature of the processor when idle (no demanding applications are running, a browser can be opened or music can be listened to, in general the load on the processor is very small) – no more than 40-45 degrees. With an average processor load (30-60%), this temperature rises to 60-65 degrees, and maybe lower, depending on the processor and cooler. And under 100% load, the temperature can reach up to 90 or even 100 degrees, but remember that if the process remains in this state for a long time, its service life is significantly reduced.
On a note! If your processor gets very hot, not only under heavy load, then you should pay attention to a cooler that cools the processor. Either it is dusty and needs to be cleaned, or there is a simple lack of cooler resources, i.e. it simply cannot cope with the heat generated by the processor and does not have time to cool it. In this case, replacing the cooler with a more powerful one will help.
To find out the critical temperature of your processor, go to the INTEL website at https://www.intel.ru/content/www/ru/ru/homepage.html or AMD at https://www.amd.com/ru, depending on the manufacturer of your processor:
On a note! You can find out your manufacturer and its model in “Motherboard”>”CPU”>”CPU Type”.
Step three. Find out the temperature of the video card
Still in the same AIDA64 main menu, in the “Sensors” tab, under the CPU temperature, there is the “GPU Diode” item, which shows the temperature of the GPU diode, or in common parlance – the temperature of the video card.
Like the processor, the operating temperature of the video card fluctuates depending on its load. When idle, the temperature will be around room temperature, at average load – 50-60 degrees, at full load – up to 85-90 degrees. On average, the maximum temperature of a video card is lower than that of processors, which determines the presence of at least one, or even more powerful coolers in the video card case.
It is worth noting that it is necessary to periodically monitor how hot the video card is under load, especially if you are an avid fan of games, video editing or 3D design. The closer the temperature of the video card is to critical, and the longer the video card is in this state, the shorter the lifespan of this same video card.
On a note! Just like with processors, the critical temperature can be found on the official website of the manufacturer of your video card.

Step four. Checking the temperature of the processor and video card under load
If you still don’t quite understand how to install the AIDA64 program, as well as determine the temperature of the processor or video card, watch the video, which clearly shows how to do this.
