Alright, my Sapphire R9 280 Dual-X turns out to be some rubbish piece of plastic! The cooler/fan did not survive getting remounted! I was switching the thermal paste on the GPU (warranty is now void) and put it all together again, got good stats in Furmark but then suddenly it raised up to over 90 degrees celsius so i checked the GPU fans and one of them is moving slowly trying to speed up ahahah... Since that moment I've been pissed off because now i cant play games.. Today i took off the cooler and was looking through every damn cable on the fans and they look all good!!
The hotter the gpu gets, the slower the fan will go and then suddenly almost stops! (the other fan works great tho.
Btw, before i got the Dual-X cooler back on i booted up the gpu with case fans on it, it failed to boot first try, but second try it worked flawless. Could something have gone wrong there, like some fan setting getting screwed up or something? Because nothing was connected on the GPU fan connector, i hooked up the fans to my motherboard.
