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.
