my card runs at about 67-70c at 55 percent fan speed overclocked about 15 percent above stock. This is for all games. my CPU hits about 57c at full load under prime 95 at an overclock to 4.2ghz, 1 hour test. My cpu cooling is a cossair h80, i've mounted a side case fan to help stir the air on the videocard to keep airflow steady and flowing to the top of the case. where it's sucked out by the H80, the case also has top vents. So i dont think heat is an issue.
As for disabling the card in the bios, Yes, i've disabled it, i only get this problem with SWTOR. No other game crashes on me like this. I can play other games for extended amounts of time and not get one crash. So i'm really at a loss to what's going on
Ok lets start with the obvious, try the following one at a time
have you run the repair utility ?
reset your bios back to defaults (leave other video disabled)
then disable sound in game and see if the crashs still occur
start enabling your previous settings one at a time if the crashs stop
