Processor temperature check program. Self-diagnosis of laptop overheating
The temperature of a computer, like that of a person, is one of the most important parameters of “health” that must be monitored, and if deviations from the norm are detected, appropriate preventive procedures must be carried out (In the case of a computer, cleaning from dust and replacing thermal paste).
From this article on the website, you will learn how to find out the temperature of the hottest laptop or processor, video card, how to conduct a simple overheating test under load, and how to interpret the results.
How to find out the temperature of a computer/laptop processor? AIDA64 program.
For control CPU and video card temperatures I use AIDA64 program. You can download the free 30-day version (we have enough functionality) from official website program developers. Or, you can look for cracked AIDA on torrents.
After downloading and launching the program, you will see the main window.
You need to select “Computer” in the menu on the left, then “Sensors”. You will see something like this:
This is on my computer in a lightly loaded state (actually writing this article - the browser is running, the FTP client is running, music is playing from VK.). We are interested in 2 parameters here, namely:
CPU temperature (CPU), and its nuclei. For me it is 35-40 degrees.
Video card temperature (GP diode) = 39 degrees Celsius.
I recently cleaned my computer from dust and changed the thermal paste, so all parameters are normal.
What temperature of the processor and video card is normal operating, and what is critical?
In general, each processor and video chip are different. To obtain accurate information, I recommend looking for the specification for a specific processor.
From my own experience, I will say that the temperature of the processor on a laptop in a calm state should be kept within 40-60 degrees. And under load it should not exceed 75-80 degrees.
Temperatures above 90 degrees are critical for any processor. At this temperature, irreversible destructive changes begin in the silicon that makes up the processor. Usually, when the temperature reaches 90-100 degrees, the device’s self-preservation instinct kicks in, and the laptop/computer suddenly turns off, saving its life. 🙂
As you understand, resting temperature is not an indicator. The most important thing for you and me is to find out what values the temperature reaches under heavy load (games, heavy programs, watching HD videos).
How to check the computer temperature under load?
I’ll be glad that you don’t need to download additional software - you can put maximum load on the processor and video card using the program’s functionality AIDA. Go to the Service menu - System stability test.
In the window that appears, check the Stress GPU box (To check the video card at the same time) and click Start. After pressing this button, the processor and video card will artificially load at 100% power.
We wait 5-10 minutes, watching how the temperature of your processor and video card rises, and how the fans in your laptop or system unit begin to spin more and more powerfully.
In advanced cases, even one minute is enough to understand that the laptop urgently needs to be cleaned of dust and the thermal paste changed. As we remember, the critical temperature for the processor and video card is 90 degrees. When this temperature is reached, it is better to press the Stop button in the test window so as not to force the device once again.
So, let's see what my computer shows after 7 minutes of testing in AIDA64:
As we can see, my super-quiet Scythe CPU cooler and GD900 thermal paste do an excellent job of keeping the i5-4460 processor temperature from exceeding 58 degrees, which I think is very good.
But the temperature of the MSI GeForce GTX 760 video card is a bit high (81 degrees). However, I did not panic ahead of time, but after googling, I came to the conclusion that this temperature for this video card is quite normal. Sometimes it happens.
What else I would like to draw your attention to in this window is the parameter CPU Throttling.
Throttling is when the processor, when overheated, begins to forcibly reduce its power so as not to burn out completely. If during the test the CPU Throttling sign lights up in red and the computer starts to become “stupid,” this also means that it is urgent to clean the cooling system.
How to find out the temperature of the processor and video card [VIDEO]
Especially for those who perceive information better visually - I posted it on my YouTube channel video on how to view PC temperature:
What to do if the processor temperature is too high?
For any electronics, high temperatures are destructive. Overheating greatly reduces the stability and service life of your devices.
So, if during a load test, any component of your computer or laptop heats up above 85-90 degrees, it’s time to clean it from dust and replace the thermal paste.
If on a computer cleaning with minimal care is possible even for a child, on a laptop everything is a little more complicated. If your hands are growing out of place, it’s better not to get into the laptop yourself, but entrust the cleaning to professionals at the nearest service center. For me, for example, the cost of such cleaning is 1500 rubles. This is the price you should be guided by.
In general, this article is more devoted to diagnosing the problem. More details about why your laptop overheats and what to do about it- you can read it on my blog site.
As I said, everything is much simpler on a computer. I will definitely tell you how to clean your computer from dust so that it turns on afterwards in one of the following articles. Do not miss!

First of all, the HWMonitor utility is a free program for measuring the temperature of the processor and video card, which additionally monitors the efficiency of fans (coolers), and also monitors changes in the operation of most motherboard modules.
A distinctive feature of the application is the presence of the Russian language, which is undoubtedly important for the Russian-speaking audience of users.
The tool is capable of receiving a wide range of statistical data from the processor, power supply, and also reports the heating temperature of the HDD and video card from ATI and NVIDIA.
How to check the temperature of a laptop or desktop PC
Information taken from the computer's temperature sensors will give the user HWMonitor programs the ability to avoid the breakdown of a single part (this applies not only to the processor and video card, but also to other computer elements that are exposed to temperature influences). Statistical information on fan speed allows you to organize detailed monitoring of the health of these computer components, whose important role in cooling the system is undeniable.The hwmonitor program can be downloaded in Russian for free (latest version) using the direct link at the bottom of this article.
It is worth additionally noting that despite the fact that users are increasingly using this program to monitor the temperature of the processor and video card, it provides a detailed report on the operation of most modules connected to the motherboard. The program developers collaborate with many companies that produce hardware components from which they actually assemble computers.
In addition, the application is able to show the minimum and maximum temperature parameters for each unit being tested. All this information can be saved using the corresponding menu item.
In order to determine all temperature changes in the components of the computer, you simply need to turn on the hwmonitor utility in the background, after which run a resource-intensive program or game. The main thing is that the application being launched is truly resource-hungry; this will allow you to clearly monitor the operating mode of all hardware devices involved in this work.
What else is this program needed for?
The HWMonitor tool is used when various situations arise: unusual computer behavior, high temperature inside the system unit, and much more. Also, every programmer or system administrator should have this program, because people with these specialties often deal with overheating of equipment and, as a result, unstable operation of the system as a whole. The software developer is the creator of the popular CPU-Z programs, which is, in a sense, an analogue of this software product. It should be noted that IT specialists advise using several utilities in parallel to ensure that the temperature data provided is correct. The following are quite suitable for these purposes: Speedfan, CPU-Z or paid version.
This tool, for all its seriousness, does not require great mental abilities from users.
Its interface is truly high-quality and detailed, so it is convenient for anyone who decides to learn about the temperature parameters of the system as a whole (including checking the temperature of the processor and video card).
You don’t need to configure anything in the program, all the settings have already been made and you just need to launch it (first, of course, you need to download and install it, it’s free). Next, the application will independently provide the corresponding temperature data for the processor, motherboard, and other parts of the system unit that have sensors.
The developers of the utility have provided the opportunity to use the program for free, which is very useful for those who want to control the components of their computer in real time.
conclusions:

The utility is easy to use, and even a simple PC user can understand it. It displays in detail in numbers the heating of the processor, HDD, video card, mat. boards and other hardware. The final results of its work can be saved on your hard drive without unnecessary movements. In the report you can find additional data that is not displayed while the program is running.We all love summer for the long-awaited opportunity to bask in the gentle rays of the sun. However, this is a truly difficult time for our PCs due to an insidious enemy called overheating.
As you know, all computer components, and especially processors, emit some heat during operation. For the normal functioning of the system, it must be diverted, ensuring optimal temperature conditions. This task becomes significantly more difficult with the arrival of the summer heat, when standard COs may no longer cope, especially if you have been overclocking your PC.
The result of overheating can be either a complete failure of the computer or permanent system instability, expressed in the appearance of strange errors, freezes and sudden reboots. To prevent such unpleasant consequences, it is necessary to keep the temperature of PC components under control using special programs, a review of which we bring to your attention.

Real Temp is a temperature monitoring program designed exclusively for Intel processors (Core, Dual Core, Quad Core and Core i7). Works under all versions of Windows and does not require installation. Data is read directly from a sensor located in the CPU core, so the utility’s readings, according to the developers, are closest to real ones. Real Temp has a warning function or an emergency shutdown of the computer when the limit values are reached. Using the application, you can also test the temperature sensor and CPU performance.
Hmonitor | www.hmonitor.net
Hmonitor is able to monitor CPU and hard drive core temperatures, voltage and fan speeds. The program has extensive customization options for displaying controlled parameters. Selecting various actions performed by the utility when the processor overheats will allow you to automatically respond to extreme situations. This could be to sound an alarm, automatically shut down the system, or run an entire script (for example, sending an email to the administrator). Hmonitor is paid (shareware) and can be used in all versions of Windows.
CPU Thermometer | www.cputhermometer.com
This program is probably the easiest to review. All it can do is display the temperature and CPU load in the system tray. The utility is a heavily stripped-down version of the Open Hardware Monitor discussed above, which retains only one function. The settings allow you to specify the color of the indication and autostart along with the system startup. However, such limited functionality had little effect on the appetite of the application - this thermometer is much more voracious than its much more advanced competitors. Despite its free status, CPU Thermometer is unlikely to be the best choice.
PC-Wizard | www.cpuid.com/softwares/pc-wizard.html
PC-Wizard is an entire software package that is capable of monitoring and diagnosing almost any computer component. This application can be used to analyze system configuration and test hardware, including CPU performance, RAM, hard drive speed, and more.

The program is intended purely to demonstrate the processor temperature, but it does this in a very unusual way. After launching Temp Taskbar, the entire Windows Taskbar becomes an indicator, on which a green CPU temperature scale appears, and the application buttons located on the panel do not interfere with its display at all. When a high level is reached, the scale turns yellow, and at critical values, it turns red. The corresponding parameters and colors are set in the utility settings. It is controlled using an icon in the system tray.
SpeedFan 4.52 is a good set of functions for monitoring and managing some PC performance. In particular, this software product allows you to monitor the temperature indicators of the processor, power supply, system unit, hard drive, etc., provided that there are appropriate tracking sensors on the computer components. However, the main function of the SpeedFan program is to regulate the rotation speed of coolers depending on the corresponding temperatures, which allows you to reduce power consumption and background noise during low use of computer resources. In this case, adjustment is possible both automatically and manually. Another feature of SpeedFan is the ability to automatically regulate the frequencies (clocks) of the internal processor bus and the PCI bus (but this should be considered as a bonus).
Key features of the SpeedFan program:
– Fan speed control.– Implemented support for SMART technology.
