Do you see a relationship between your computer's idle temperature and the temperature in your room? When I first did my 3Ghz OC, the room temperature was 22 degrees and the idle core temperature as measured with CoreTemp 0.95 was 34 degrees - and I was happy. As summer took its toll my room temperature went up to 30 degrees and the idle temperature of the cores 42. Right now we're in the midst of a heatwave, hopefully we'll get over it this week - the temperature in my room is a suffocating 38 degrees and the idle temperatures of the cores is 50! It seems that no matter what my room temperature, the core temperature would always be 12 degrees higher. Now I wish I bought an air conditioner - I checked but now they're so busy they wouldn't be able to install one until mid-August, and by then the temperatures would be in the high 20's again, so I'll be booking one for next summer. I've been having no problems though - just bought oblivion and been playing it for nearly 12 hours straight during the weekend, with settings all maxed out except character shadows and shadows on grass and I never got a crash and the lowest FPS I got was 25 in rare times while in the middle of the grass, and mostly it's over 50 in the forests, over 70 in the towns and over 100 indoors. I don't know... shall I dare take a TAT test reading? Eeek!
