Hi, I recently acquired a couple of R9 290X cards and I changed the temp target to 85C as I don't like the idea of a GPU constantly running at 95C, even though AMD says it's okay. Anyways I was testing a few games, and noticed that in GTA V specifically, the temp limit I set was completely ignored. Other games I tried were Overwatch and BeamNG.drive, and in those games, the temp target worked as expected. There might be more games that this issue applies to, but out of the games I've tried, GTA V is the only one.
CPU: Intel Xeon E5-2670
GPU: AMD Radeon R9 290X Reference
