After doing the changes, you can save the new configuration and start using the pc.

You have to choose PWM mode if you really want the speed to go down (like 10% of the max speed or so). You should bear in mind that you can’t reduce the voltage below a certain threshold and therefore, you can’t really slow down the speed to a minimum such that you hear no noise. If you choose DC mode then you can only adjust the supply voltage. Once you enter the BIOS, you can look for Fans, select PWM mode, and then finally adjust the speed-to-temperature graph ensuring that the Smart Fan Mode is turned on. Press F2 or Delete key when your PC is botting up (the keys maybe different depending on your motherboard).Press and hold Shift key and then click Restart.You can open the BIOS Dashboard in either of the two ways: In my case, the Antec Prism fans are PWM fans so I can precisely control what speed I want them to run at. The PWM fans allow for a seamless and high-precision control whereas the DC fans lack precision as their speed is controlled by varying the supplied voltage. The PWM fans are 4-pin fans whereas DC fans are 3-pins. PWM fans are DC fans but with an extra wire for PWM.

With the help of a software (Dragon Center for MSI Motherboard).īefore we dive into how to control the fan speed, we should be aware of the two modes the fan operates in – PWM and DC.

There are two ways you can control the fan speed (RPM) in your PC: Having said that, the process should be similar for other fans and motherboards. In this blog post, we are going to see how to control the fan speed/RPM of Antec Prism ARGB 120mm fans on a MSI X570 Tomahawk Motherboard.
