I see these unstable issues on my GA-Z170X-Ultra Gaming. I put down the entire Gigabyte apps. All of them. SIV does have issues on the fans. everytime is a different profile or settings or speeds or variations, I change the fans and same thing. I drop all, put fans on normal, pump on full speed, and that is it. Remove my front PWM fans, put a 140mm ring that was the only fan without noise here, all is connected to the PSU and that is that. I am running the last beta before the F20, I think gigabyte has to address these ASP, is starting to have the same faith as Asus, all their PROGRAMS and bios are BAD... i get these board to discard the CPU, 2 asus boards RMA, still pending on that. and now these. i am very direct pointing the finger to MS on some areas. and i can prove it.!
