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?
