Hey Guys,
I created an account just to say I am having the same issue. I currently have only 1 2680 v2 and am experiencing temperature spikes / fans getting stuck at 100 percent. I am using this motherboard for a home lab build, so the fan spikes are getting pretty annoying.
I really feel like this is an issue with the BMC, I am on version 18.0. I emailed someone at ASRocks who appears to know his stuff, will let you know what I find out.
Have any of you tried reverting to an older version of BMC? I may if I get desperate enough.
Thanks
