I am running my 2500+ with an SLK-800 w/SFII and AS3 at 3200+ and both my Asus bios and MBM 5 report the case temps in the low 20's fluctuating with the room temp. The cpu temp is reported by both as 41C constantly, unless I've been playing videogames or experimenting with encoding software, when I've never seen it go past 43C.
