After I switched my PSU to a RM550x and having to take out the card to do it my GPU has been setting 2 of the 3 fans to a 100% and the last one is just off.

I turn on the PC after everything is in I run Heaven for a couple of minutes and everything seems fine. Then I don't quite remember what I was doing 2 of the 3 fans just go to a 100% and I can't seem to control them in any way. MSI Afterburner has no control over it so I restart the PC and it does the same thing on boot, I then powercycle and it seems fine until I up the fan speed in MSI Afterburner and then it's back to the same. I restart again and run Heaven and same thing once it hits 55c.

Anything I can do about it or do I have to send it back to ASUS?
