System fan RPM spiking
Posted by GameDial@reddit | buildapc | View on Reddit | 1 comments
Hello. I'm trying to increase the RPM of one of my system fans. I tried increasing the voltage for the system fan in the BIOS settings. Anything over 7.20V makes the RPM occasionally spike from 900ish to 1700ish for 1 second then straight back down again.
Why does this happen? Is the fan broken? Does it matter?

Didn't need with voltage. There should be a fan curve in your bios. Change the curve so that or runs faster at lower temps.
There is also 3rd party software to manage fans like Fancontrol.
