At idle it sits around 52 and under load (CS:S maxxed completely, and Halo 2 maxxed) around 82ish give or take 3 degrees. I want to keep it a little cooler. I have riva tuner but I do not know how to change fan speed. Also how do I view CPU temp from Riva tuner? Also what I noticed when putting in my GPU I saw on the edges around some of the chips on the video card board it looked like there was gobs of white thermal paste outside the chip. Looks like they used too much.
