If your CPU fan is making too much noise or it’s not running fast enough to cool down your PC, it’s time to change its speed.
Though you can change the CPU fan speed through BIOS, this article covers how you can achieve that without it.
It’s possible that you’re unable to change it via BIOS or you don’t want to mess up the process and brick your PC.
If you’re running Windows 10 or 11 on your desktop or laptop, this article will show you how to change CPU fan speed without BIOS.
Also, most of the tools allow the users to adjust, control, and monitor the CPU fan from the Operating System level without accessing BIOS – that means – we don’t need to restart the computer.
Why Should You Change the CPU Fan Speed?
If your CPU fan is unable to cool down your desktop components, you need to increase the speed. Doing so will result in better internal airflow inside your device. This can save your PC from overheating.
If your CPU fan is not functioning at the rate it’s supposed to, it’s necessary for you to manually increase the speed for cooling down.
On the other hand, if your fan is making too much noise, you may want to decrease its speed to an optimal level. However, keep in mind that reducing it too much may cause overheating.
Can You Change the CPU Fan Speed Without BIOS?
Yes, it’s certainly possible to change the fan speed without accessing the BIOS. Though it’s still the recommended method of doing it, it’s not a requirement anymore.
There is a bunch of software and external hardware in the market that lets you control your CPU’s fan speed. We’ll talk about them in a moment.
There are multiple methods and products you can use to change the fan speed of your CPU. We will cover each one in-depth and tell you which one will be best for you so stay with us.

Which Fan Speed Controlling Method is Best For You?
Although it’s recommended to change the fan speed using BIOS, it’s understandable if it doesn’t work sometimes.
If you’re tight on budget and don’t mind going through some expert tutorials, you can get one of the software we mentioned.
If you want more convenience and freedom in controlling the CPU fan speed, getting an external speed controller is the way to go.
What Speed is Good For Your CPU Fan?
An optimal speed that keeps your PC cool enough but is also not too loud
You generally set fan curves according to your preferences based on noise and temperature. It’s certainly not universal, and random numbers are not helpful when you run a completely different setup than someone else.
Some users like to set their fans to 600rpm unless it gets really hot during summer, then they set a higher RPM.
Other users set it so that the max daily temperature stays under 75 °C and if they have thermal headroom then they lower the fans to lower the noise.
As you can see it depends on your device, room, and geography, among other factors.
So our advice for you is to make your own fan curve accordingly.
