Earlier today I decided to try out the Fan Xpert fan optimization feature (worst decision of my life right now). All my fans used to run normally, but now one of my chassis fans will rev up to 100%, then go back to normal, and then sometimes turn off completely, as well as the LED on the fan turning off completely as well. My 2nd chassis fan is working just as it was before this mess. As far as I can tell, both fans have the same exact settings in the Asus BIOS tool, and I've tried my best to fully uninstall and Fan Xpert and the other ASUS utilities. I even tried reflashing(?) my BIOS. I am still stuck with this issue and any help would be appreciated.
