I've just bought a second-hand XFX 6800GT (AGP). I've fitted a huge copper Alphacool NVXP III water cooling block.
I'm using LCD Smartie with the NVTemp plugin to display the temperature of the GPU. The card was sitting at around 45c for normal desktop use, but it randomly jumps upto 309c, 140c, 90c etc!! (it changes from one minute to the next)
Using the latest Forceware GPU monitor, these sporadic temp changes are recorded here too.
Do you guys think I need to roll-back to an earlier Forceware driver to solve this, or could it be a duff temp sensor on the 6800GT itself?
Any advice appreciated!
