I was running a graphics program and would get the occasional artifact (small colored dot) popping up, so then I tried ATITool scan for artifacts and would get an artifact every once in awhile, or so it seemed to detect. The temp of the graphics core only seems to go up to 85c. Do you think it is some sort of program or driver bug or if I should try raising fan speed? (I don't really want to though because it might create more noise.) There's no overclocking on the card.
