Turned on my PC 20 minutes ago and it sounded fine until my monitor showed the login screen at which point my GPU fans started making a much louder sound than usual. So naturally I restarted but the problem persisted. So I logged in and checked HWmonitor, and all the values seem normal except for the fact my fans are apparently spinning at 0 rpm which they definitely aren't. I've loaded up a couple games are it seems to be working properly except for whatever is going on with it.

Any ideas?

Ok quick update: After being on for about half hour the gpu just made sound then it stopped spinning so fast and HWmonitor is showing the fan speed as normal now. I'm very confused.
