System Temperatures on Full Load

Your Temps are a bit high but not bad your 9800GT is way too high if it is just idling make sure your case fans are all running in right direction also you can download EVGA precision or Rivatuner and adjust the fan speed on your 9800 GT. Your CPU temps are about normal for a stock heatsink a little high but nothing to worry about there. I think your case might be suffering some airflow problems though since your hard drive is running a tad warm too.

Download RealTemp for CPU temps. EVGA Precision for GPU temps.

Bump.

I've realized my system temp never changes, it is always 83C....

I have an evga 750i SLI FTW motherboard....Bios reads around 35 degrees for system temperature, I also did not see it fluctuate at all over 10 minutes in bios....could speed fan be reading it wrong? Thanks!

Very very possible. Sytem temp isn't important anyway. And it's won't change in the bios, your system is running at a steady state. You could get a can of circuit board freeze and try to find the sensor.

Coretemps under idle and load using something like Realtemp is all you need.

Take a look at HW Monitor too, I like that one.
