Excessive heat can harm the CPU?

Dec 24, 2019

More importantly, many users have since asked the question, "Is a too high temperature harmful to the CPU on the machine?".

The short answer to the above question is both yes and no!

Extreme temperatures do not necessarily cause immediate damage to the CPU, but if this situation continues for a long time, it will certainly make your PC reduce your life and easily see damage.

Specifically, for desktop platforms (desktops), when the CPU is running at idle, the temperature of the chip overheating completely is not a problem if the PC is still running stably. Because if your CPU reaches a dangerous temperature threshold, the hardware protection mechanism will be activated and automatically power off or reduce the CPU performance, before high temperatures cause any damage to the device. inside of you.

So what about laptops? This device platform is definitely more complex than desktops, when CPU and GPU cooling is confined to a small space. However, most modern laptops are also equipped with a "thermal defense" mechanism. When the temperature is detected too high, the computer will automatically turn off and prevent any damage to the CPU inside the laptop. Before that, you will also feel the performance of the decrease because the defense mechanism has reduced the CPU / GPU pulse to bring the processor chip temperature to a safe level.

So if your CPU is overheating, the device still has a way to protect itself and you don't need to worry. It is worth noting that if the CPU is overheated for a long time, it will greatly affect the experience of using your device, reducing the life of important hardware such as hard drives, RAM and circuit boards.

How much temperature is called dangerous?

To know what the temperature on the device is, we can easily use many of the available applications such as HWMonitor or HWiNFO 64, running these software in parallel for gaming or when using heavy applications. to check the temperature when the PC is running at high power.

However, users should not leave the device running at high temperatures for long periods, which can easily reduce the life span and unnecessary damage.

If the CPU is in idle mode (running light tasks) but the temperature still reaches 80 degrees C or higher, it's time to check and clean the machine as soon as possible. This may be due to the poor performance of the cooling fan, the cooling cream has stopped working, the heat exhaust is covered with dust, etc. Remember the ideal CPU temperature threshold on the desktop should fall between 50 and 70 ° C.

For overclocking cases, be careful because in theory, the temperature can now be up to 90 ° C. While still within a safe temperature range, not exceeding the threshold 105 - 110 ° C for most CPU models, but do not overdo and use the machine at too high temperatures for a long time, you will easily cause your device to reduce life expectancy, failure at any time. The advice here, if you overclock and maintain the CPU at high temperatures, try to keep the temperature below 80 ° C, the highest should not exceed 85° C.
