Does Bios Control Fan Speed?
Contents

The BIOS menu is the place to go to adjust the fan speed.

Does Windows or BIOS control fan speed?

The easiest way to control a cooling fan is from the BIOS. Choose a fan type (DC or PWM), set a mode, and set a temperature threshold. Speedfan is a popular third-party software option for controlling a CPU.

Can you control fan speed outside of BIOS?

If your computer’s BIOS doesn’t allow you to adjust the blower speed, you can choose to go with a speed fan. This is one of the free utilities that give you more advanced control over your CPU fans. SpeedFan has been around for years, and it’s still the most widely used software for fan control.
