Just tried 12.8 drivers...started good with temps in game sitting in the 75-85 range...after a minute or two voltage went up to and stayed at 1.22 and temps were back to 100c...I pulled off the side of the case and touched the card casing. It didn't feel hot enough to the touch for it to be 100c, and it wasn't blowing super heated air from the fans...I'm confused now.
And since I've closed the game I'm back to .82v and 34c idle temp.
