I would like to start with saying that I've been up all night breaking my brain on fixing this issue. So if I miss something / don't give enough info please ask and I will gladly give the info needed.
Card: AMD Radeon HD 7900
Driver version: 9.14.10.01162. Crimson 15.12
At the time of this post my idle temp is 88C. I JUST reapplied thermal paste to the gpu. It seemed to slow the climb from when I turned on the computer. That is about all the help it provided.
Fan is running at 3260 rpm (not sure if that is low) while at 100%
gpu usage is at <10% to 0%
I have cleaned all heat sinks and fans; and reapplied thermal paste.
When I put the card under load (started at 79C), 84% load, the temp spiked to 97C in a few seconds. I shut down the game and the temp dropped and stabilized at 88.
Any and all ideas would be appreciated. For now I'm off to bed
Thanks in advance!
