I have had this happen a few times, but not often. All of a sudden the fans will speed up to high RPM, causing sounds the way a server would.   Rebooting usually fixes it.
Curious if any others have seen this. Since I purchased the machine after a bit of time (totally varies, usually after a couple hours) the fans quit responding to AWCC. Ran into the screaming fan noise that others have seen (loud base fans shipped with box). Decided to replace the loud fans with noctua fans. Very quiet now but still have issue with fans responding to AWCC control. Works great usually a couple hours, does not matter the load (browsing or heavy game play) then quits responding. Actually even without AWCC as box gets warmer fans don't adjust. Have seen where the fans might be at 30% and never move no matter the temp or full on 100% no matter the temp. Have removed and reinstalled AWCC multiple times and seems to work great up to the 'magic' time lol. Having to reboot when this occurs is not a huge deal just a pain. Thanks
