do you have coverage on you mobo if so get it replaced... that may be the problem and there is really no way to test it unless a new one is installed and tested if the problem stops
also try plugging you cpu fan plug into the SYS_FAN if that does not make it spin then you almost definetely have a bad mobo
I tried plugging it into the other fan spots, no change. I also really don't think it is a bad mobo, as this is my second new one with the exact same problem. The chance of getting 2 bad mobos in a row with the exact same issue seems really low. The chance of me being dumb and missing something seems higher. Or maybe a bad CPU, since that has never been replaced, but it is no longer under RMA (since I spent so much time RMAing the motherboard) and I would rather not buy another CPU.
