What Is The Fastest CPU Fan Speed?

How To Adjust CPU Fan Speed

The main way to check the speed of your fan is through the computer’s software.

BIOS Settings

If the computer is already on, you need to restart it. The computer should be turned on if it is switched off. This will allow you to get to the speed controller for your fan. 

The system setup can be entered if you press the key. In most cases, this key is called the F12 key or the Delete key. You can go to the Hardware settings by clicking on the settings. You can see the current fan speed by clicking on the Fan settings.


If you want to check the fan speed on your PC, you need to know if the manufacturer has specific software for that. It is always best to use a tool that is specific to you. 

Generic third-party Apps with good reviews are a good choice if there is no specific tool or App. Two of the most sought-after choices are the MSI Afterburner and SpeedFan. It is a good idea to use the Mac Fan Control utility tool if you have a Mac system.
