All computers use a fan to prevent the central processing unit (CPU) from overheating. In this post, I will help to let you know how to turn off computer Fan by sharing 3 Possible Ways to Disable Fan so as to cool down the processor and get rid of needless noise and overheating.

Fans in most computers are used as the primary means of cooling for critical internal components and often heavy loads on the processor and video card can cause a drop in the operating speed of the PC. It is vital to monitor and maintain the good temperature of CPU to avoid damage to other components and thermal throttling caused by overheating.

Depending on the fan type like DC or PWM, its noise level, operating speed, and, as a result, the computer performance and cooling efficiency may differ.

Software to control and disable fan speed

The main limitation of such software is that to turn fans off will only work on adjustable fans and most of the fans aren’t adjustable.

You can check the fan software, if any of the above-given works for you then you can download them that let you turn on/off or regulate the speed of the fan and other fan control functions with a huge range of possibilities.

Note: Strange noises like the grinding sound of a fan is one of the bad signs of power supply failure.

Final Words:

If the 1st way is not accessible for you then I suggest using the 2nd way to disable the fan because it is easy and simple. The 3rd way is very limited to the users due to the lack of availability of adjustable fans.
