Command to check processor temperature. Computer temperature and what they should be for different components

One of the factors affecting the speed of a computer/laptop is the temperature of the processor, video card and other components. The higher the temperature, the slower the computer/laptop will work. If the processor or video card is overheated, it may fail, and long-term operation in high heat mode reduces its service life. At critical temperatures, the device will turn off spontaneously (overheating protection is triggered). To prevent overheating of the processor, video card and other components of the computer/laptop, it is necessary to periodically monitor the temperature and, if it reaches critical values, take measures to reduce it. How and with what to check the temperatures of the processor and video card and how to reduce the temperature will be described in this article.

There are two ways to check the temperature of the processor, video card and other computer/laptop components:

1 View the temperature in the BIOS;

2 Use third-party programs.

Find out the temperature of the processor and other components in the BIOS.

In order to get into the BIOS when booting a computer or laptop, press the F2 or Del key (the buttons may differ, depending on the model motherboard). Then in the settings you need to find the Power/ Monitor menu in different versions BIOS will be different. There you will see the temperature of the processor, motherboard, etc.

Let me give you an example of how I looked at the temperature on the motherboard ASUS board in UEFI (Unified Extensible Firmware Interface - a replacement for the obsolete BIOS, used in modern motherboards). Once you are in UEFI, click the "Advanced" button.

After that, go to the "Monitor" tab, you will see the temperature of the processor, motherboard and much more information.

Thus, without installing any programs, you can find out the temperatures of computer/laptop components. The disadvantage of this method is that not all motherboards have this option and it is impossible to view the processor temperature under load (when running “heavy” programs or games).

Find out the temperature of the processor and video card using programs.

There is a large number various programs, which will show you online the temperatures of computer/laptop components. In this article I will analyze several such applications and give my assessment of their work.

Find out the temperature of computer/laptop components using the AIDA64 program.

AIDA64 is one of the most popular program for review and diagnostics of a computer/laptop. AIDA64 provides comprehensive information about the composition of the computer: hardware, programs, operating system, network and connected devices, and also shows the temperature of all computer/laptop devices.

Program window showing temperature data from sensors.

It should be said that the program is paid and the trial version (30 days) does not show information about all devices - in my opinion this is the main disadvantage of this program.

Find out the temperature of the processor and video card using the Speccy program.

Speccy is a small utility from the developers the most popular application to clean your computer system garbage CCleaner. When launched, Speccy monitors the computer hardware and displays information about the operating system, characteristics installed hardware and data from sensors.

Below the program interface.

In my opinion, one of the best programs to determine the temperature of the processor, video card, etc. In addition to information from sensors, it also provides a detailed analysis of all the hardware installed on the computer/laptop. The big advantage is that the program is free.

Find out the temperature of the processor and video card using the CPUID HWMonitor program.

CPUID HWMonitor - a program designed to monitor the performance of various computer/laptop components (temperature, fan speed, and voltage).

Below is the interface of this program.

In my opinion, the ideal solution for those who are only interested in information about the temperature of all PC components. No unnecessary information, just temperature and fan speed, plus minimum and maximum values Moreover, this program is absolutely free.

What should be the temperature of the processor and video card.

Different processor manufacturers set their own temperatures, but generally speaking, the temperature should be between 30-45°C at idle, up to 60-65°C under load, anything higher is considered critical. Let me explain that these are average values; more specific information should be found on the website of your processor manufacturer.

For a video card, the normal temperature is up to 50-55°C at idle, and under load up to 75-80°C. You can find more accurate average values on the website of your video card manufacturer.

What to do if the temperature of the processor or video card is high.

1 Clean your computer/laptop from dust. Make sure all coolers and vents are free of dust. This is the most common problem overheating of the computer, laptop. To fix it, you need to disassemble the computer/laptop and remove all dust that interferes with cooling.

2 Replace thermal paste. Thermal paste is a layer of heat-conducting compound (usually multi-component) between the processor and the heatsink. Over time, this paste dries out and loses its properties, causing the processor and video card to overheat. To replace it, you need to disassemble the computer, remove the old thermal paste from the laptop and apply a new one in a THIN layer. Typically, thermal paste is replaced when cleaning the computer/laptop from dust.

3 Replace the radiatorcooler. You should choose a better quality radiator, cooler for better cooling computer. In addition, it is quite possible that you should additionally install a cooler on the case for better heat removal from the computer.

I hope I helped you determine the temperature of the processor and video card and you were able to reduce it and achieve faster and stable operation computer/laptop.

Heat dissipation modern processors, amounting to several tens of watts, requires reliable operation of the cooling system. Dust accumulating in the radiator or a malfunctioning fan can lead to the heating of the computer's main chip crystal to dangerous temperatures (more than 100 degrees). To prevent this, processors have built-in temperature sensors. The data obtained from them is used motherboard for emergency shutdown of the computer in a critical situation.

You can find out the processor temperature before the system boots by logging into BIOS setup. To enter the mode BIOS settings it is necessary to press a special button at the beginning of the computer boot, most often it is “Delete”, sometimes “F2” (in motherboards Intel boards) – in any case, a corresponding prompt will appear on the screen (“BIOS setting F2”, “Del BIOS setup”, etc.). The location of the required section in the menu may also vary.

For example, like this:

This is what he looks like" Hardware Monitor»:

CPU Temperature - this is the temperature central processor. IN in this case it is equal to 34°C. Here you can also see the fan speed and system supply voltage.

Another option:

In this case, the required section is called “PC Health Status”, translated as “Health status of a personal computer”.

“Current CPU Temperature” - “Current processor temperature”, in this example it was 29 degrees.

There are also other names, such as “H/W Monitor” (short for “Hardware Monitor”). In any case, this BIOS setup section is not difficult to find, and it makes it possible to preliminary evaluate the performance of the cooling system. If already at this stage of testing the temperature quickly rises to fifty degrees, it is recommended to urgently check the condition of the radiator (the degree of contamination of it with dust), the fan and thermal paste (which may have dried out).

More objective data on the processor temperature while working with the programs you are using can be obtained using special utilities, which are often available on the disk included with the motherboard (they can also be downloaded from the manufacturer’s official website support.asus.com.tw by selecting the product, series and model, then operating system and go to "Utilities").

Example - “PC Probe” from Asus:

There is also a special software, which can work with any motherboards and processors. From free programs Of particular note is Core Temp. The official website from which you can download this application is www.alcpu.com

This is what the Core Temp window looks like:

From the screenshot you can see that the program shows significantly more detailed information than the utility from the motherboard manufacturer. You can find out not only the temperatures of all processor cores, but also the frequency at which it operates. at the moment time. The program supports Intel processors, AMD and VIA. Through the “Service” menu you can get even more detailed information about the system and take a screenshot. In the “Options” menu, it is possible to enable overheating protection, and the program will notify the user when the processor reaches the specified critical temperature, you can also automatically turn off the system or put it into sleep mode after a specified period of time.

Favorable temperature regime is the key to a stable operating system. You shouldn’t be surprised why your PC began to work slowly and somehow “behave capriciously” when your ear hears extraneous metallic noise, your nose smells an unpleasant burning smell, and your eye involuntarily notices a cloud of dust when you start the computer. All this suggests that the “iron health” of your electronics is under threat. It may well turn out that by learning today the answer to the question: “How to check the temperature of a computer?”, you will save your PC from certain death. If you think that they are scaring you in vain, read the article and you will understand that everything is much more serious than you imagine...

Strange introduction and clear comparison

We are all familiar with a basic self-diagnosis device - a thermometer. A fairly simple medical device helps determine the level of threat to our body and take timely measures to restore temperature balance. Note that the feeling of weakness does not cause us as much anxiety as a fever that appears out of nowhere. However, even a slight malaise affects our performance, not to mention the inflammatory processes that chain a person to a hospital bed. The scan program can warn you about problems with your PC. The system thermometer will always be in front of your eyes, and you will be able to respond in a timely manner to critical indicators of the performance of your PC. Let us leave the biological comparisons and move on to the main part of the presented review.

So, about the signs of overheating

Before you learn how to check your computer's temperature, let's take a look at the main symptoms of electronic fever:

Your PC began to reboot spontaneously.
significantly lost in performance.
Unauthorized closing of applications and resetting of working windows.
Distorted image display on the screen: ripples, stripes, blur and other interference.

Of course, all this can be avoided if you systematically monitor the condition of your PC. Unfortunately, Windows system does not have a sufficiently accurate diagnostic tool, and true temperature readings are only available in the BIOS. As you understand, without third party software there's simply no way around it.

How to check your computer's temperature: several effective ways

Today there is an unimaginable number of different utilities and software, through which the user can obtain current “degree” information about each hardware component. However, not all of them deserve to be called truthful. Some of these utilities take readings from temperature sensors with a monstrous error. Which makes their purpose, much less use, pointless. Well, let's look at some "honest" and "reputable" software solutions.

AIDA64 is a leader among the first!

Small, but very effective program. By installing this diagnostic tool, you will save yourself from the problem of “How to find out the computer temperature?” Literally all the information (and in detail) about the hardware configuration will become available for review.

On the left side of the program window that opens, click on “Computer”.
Then go to the "Sensors" section.
On the right side work area the entire list of “heat-intensive” equipment will be displayed.

However, such information is unlikely to be useful to the uninitiated user. After all, it is necessary to understand what temperature value is critical. At the same time, do not forget that different components heat up in their own way.

Computer temperature monitoring: dangerous sensor reading

Depending on the type and class of system components used (meaning PC hardware), the manufacturer provides certain operating parameters for the part. Nevertheless, the “temperature list” presented below can be considered universal, since the endurance limits specified by the manufacturer always imply ideal operating conditions. Something that is practically impossible to achieve in real life.

CPU

So, how can you check your computer's temperature? The first monitoring point has always been the CPU.

When performing non-resource-intensive operations (for example, when working with an indicator in the range of 30-45⁰, this is the norm.
When the computer is idle, the numbers drop to 25-30 ⁰C.
An unfavorable temperature is considered to be 60-65 ⁰C. This “scenario” most often leads to processor failures. The “Throttling effect” occurs - the CPU begins to work in skipping clock mode, thereby reducing the temperature of the “hot” flint.
The critical value - 70-85 ⁰С - will cause spontaneous reboot. In some cases, this temperature can completely damage the processor.

Video card

When you manufacture a computer, in particular GPU, the following should be taken into account:

For modern video cards, a value of 60-65 ⁰С is the norm. Whereas this temperature can “kill” old GPUs.
The powerful video adapter is equipped with an appropriate cooling system, so when working for many hours in game mode even at a value of 85 ⁰C, the user does not have to worry about the “viability” of his graphics processor.

When downloading resource-intensive “toys” onto a PC, you need to adhere to technical characteristics your video card. Since graphics distortion, braking effect, or spontaneous exit from the game to the desktop are not always a manifestation of a “temperature” malfunction.

Motherboard

Of course, a practical solution to the question “How to check the temperature of a computer?” Without mentioning the main part of the PC, it would be incomplete, to put it mildly. However, so important element How motherboard, in general, is not included in the “temperature risk” group. Because overheating of the chipset is currently an extremely rare occurrence. In some modifications, the motherboard temperature of 50 ⁰С is quite normal indicator. Whereas, ideally, the “working degree” should not exceed 25-35 ⁰С.

Hard drive

First of all, it is worth noting that the location of the hard drive when monitoring the computer temperature has great value. After all, the design feature hard drives is the absence own system cooling. As practice shows, not every user equips their HDD with a special additional cooler. Which is unforgivable, by the way... Hard drive is a heat-consuming element electronic systems, and therefore, if there is insufficient cooling, it can be subject to the destructive process of overheating.

The ideal temperature is considered to be 25-30⁰С.
Critical indicators are 50⁰С and more.

Load temperature diagnostics

The above-mentioned program for checking computer temperature - AIDA64 - has a built-in System tool Stability Test. If you want to see how your PC hardware works in real time, use this utility:

Activate the "Service" tab.
Next, select “System stability test” from the context list.
In the window that opens, mark the items of the equipment being tested.
Continue by clicking on the Start button.

If any of the main components of the system is subject to overheating, the utility will automatically stop the test and report a specific “violator” of the temperature regime.

What should the temperature of the video card be?

So, you installed one of the programs, looked at what it shows and... What's next? What is the normal temperature of a video card? How to understand: is it heating up or not?

Maximum permissible temperature The video card differs slightly depending on:

manufacturer (Nvidia and AMD);
type of cooling (active and passive);
operating mode (on the desktop or during the game).

Nvidia and AMD video cards can be either active or passive cooling. But overall, big picture relatively normal temperature should be clear.

The video card on the laptop overheats: what to do?

What to do if you find that the video card on your laptop or computer is overheating? Urgent measures need to be taken:

Perform dust cleaning. Most often, overheating occurs due to its large quantity. Therefore, it is recommended to disassemble your PC or laptop to clean it from dust.
Check the condition of the thermal paste. It is responsible for cooling the video card. Therefore, when it dries out, the GPU temperature will increase sharply even in idle mode. In this case, you need to apply new layer thermal paste.
Check coolers. They may be faulty or perform poorly due to dust.
Check the power supply. If it is faulty, it can lead to problems with the video card (i.e. overheating).

If you can do it all yourself, great. If not, ask your friends or service center for help.
