Most computers today are designed to turn off automatically if any of its contents get too hot. Typically, heat related problems occur when the computer is active, for example playing intense graphic computer games.
You should check your computer fan to see if it moves quickly and smoothly. If the fan noise is heard, it is because it has to operate excessively to cool other parts of the computer. Open the computer case to check the inside, see parts like the processor (heat absorber), video card and computer case fan.
Note: If your problem occurs on laptop you should not turn on the machine and instead check the fan next to the working computer for hot steam. You should buy a heatsink to help reduce the temperature.
The safe temperature should be 45-50 degrees Celsius and the maximum temperature should not exceed 60 degrees Celsius. You can check the system temperature in the BIOS (Basic Input System). But note not all BIOS will display this information. If you are not sure how to access the BIOS, you can refer to the article How to access the BIOS on different computer models or search Google for the keyword “brand name + access to BIOS”. You should follow the steps in the manufacturer’s website.
You can also use the free utility to see the system temperature. If you’re not sure which utility to use, you can give HWMonitor a try. It’s made by CPUZ and you can count on it.

If the temperature is high (above 60 degrees Celsius), you can do the two things below.
For desktop (Desktop)

- Open the cover of the machine body (case) and check if the internal cables are blocking the air slots of the machine.
- Blow away dirt inside with a blow tool dedicated to the computer.
- Check one last time by turning on the computer with the body still open (case) and making sure that the blowers are working properly. If the fan stops working, the temperature will be higher than normal. So open the computer case and make sure the fan is running, if the fan fails, replace it with a new one.
For laptops (Laptop)
- Check where the laptop is located: Never put it on a pillow or blanket because they will block the air slots of the laptop.
