Hi!
Im pretty novice about Gpus and found this thread when i was googling, so was wondering if any of you more advanced gpu guys know anything about my problem.
i bought two R9 290 Tri-X OC and they worked fine first ours. But now i cant change the fan anymore on one of them?
Fans spin but will not increase how hot it gets .. Is there a reset switch etc. .. or what can I do?
Tested gpu in another computer with the same results, running at standard speed despite 90 degrees in the Valley Bench

Would be very grateful for some advice so i can start to play with the mining settings.
