I know these cards won't overclock that well, but mine stays at 51c. When I installed the drivers it came with, the temp was at 86c. I immediately installed the latest drivers 91.31 and the temperatures went down. Then I installed the BETA drivers as coolbits or rivatuner didn't work with the 91.31 drivers. I installed coolbits and rivatuner again and they still don't let me overclock. The new Nvidia user interface has thing automatic overlclock thing instead of a manual adjustment one. Any ideas as to what I can do overclock this thing?
