I am writing this on my i920 system oc'd to 4ghz. Not quite idle as email, av and browser are open. Real Temps shows load under 2%. Temps= 39,35,40,36. Prime 95 after about 5 min (as an example just for this reply) with Large FFT 68,67,67,64. The room ambient is about 23(all temps are Celsius). I use a Noctua NH-d14 cooler with the fans set to slow speed (900 rpm). Hope this gives you some reference.
