Just got my step up 6800 Ultra today from EVGA, and I am trying to install the new Koolance GPU block. However, my GPU temperature is 66 at idle and 95 under load, seems a bit high for watercooled to me. The GPU is the first block in line, and my CPU seems to be running at normal temperature. I have bled the system several times, and there are no air bubbles trapped in the GPU block. Is it possible that the mounting screws on the video card may be too loose/tight? Do I need some sort of shim in there? Help!
