WOW... yeah I have been unravelling this for the past hour. It appears that fan control was set to disabled. But I did set it to auto and now it is at 0. FWIW I am on BIOS v4804.
So maybe you or someone else can help me. Is AI Suite necessary? The whole reason I found out about this is that I am running performance runs w/ my software and noticed my CPU is taking cycles on aaHMSSvc.exe and atkexComSvc.exe. These seem to be from this suite and I am thinking of uninstalling it altogether.
I would say that I would do this after I update my BIOS, but now thinking about it I think doing so will erase all my settings, and I recall telling myself four years ago that I am happy with the settings. 😉
