I have an XFX graphics card with an Nvidia GeForce 6800GS that is running temperatures between 64 and 68 degC during normal operation. That seems a little high to me. The fan is working, I just cleared fan and heat sink of dust, and it still seems to run hot. I haven't played games in a few months on this graphics card, but I remember playing NFS Most Wanted a few months ago and even though I had the video settings set the same as I did more than a year ago when I played the game all of the time, the game was freezing and skipping not like it had ever done before.
I know I have gotten my CPU temps down by cleaning the heat sync and the processor and applying new thermal paste, but this GPU is one with a whole contraption of stuff surrounding the fan and heat sync. How hard is it to get to the processor on these cards? Should I just get a new graphics card?
