Pick up a copy of Riviatuner. just google it.. Has a bit of a learning curve but will do the job very well

Thank you very much Davet50 for the information.

If you are using the included nVidia System Monitor for your temperatures, then those are most likely false. It gives me wrong temperatures on my CPU so it's a bit glitched. 116C is pretty much impossible for an 8600GT as those run cooler than an 8800GT, and 8800GTs never get much higher than 100C. So I wouldn't trust nVidias system monitor for temperatures, most likely you graphics card temp is half of what the sys monitor says it is.

Thanks X Matt X for that info. I seem to have read the very exact thing somewhere. The 116o was 116F not 116c which would put it close to 114F. Would that be closer to being correct? I may have stated it wrong earlier.
