I'm having that same problem (I hope, because that would mean I'm at 31°C...)
I have a Swiftech MC370-OA cooler on my cpu, and according to the reviews, it should be at 35°C. Asus Probe 2.12.07 is reporting that right now that I'm at 41°C (earlier this afternoon, it was at 45°C, probably because it was a bit hotter and now it's freezing! j/k)
At first, Asus Probe (and MBM 5) was reporting 48-49°C. So, I got two 80mm fans: one intake at the front-bottom of the inside where there's this black thingy, I took it out, stuck it in there to intake air, and closed it up. The other went into a designated area for a 80mm fan on the back panel. I flipped the fan so it would exhaust air. Now, it's at 41°C. If the reading is 10° higher, then that would mean I'm really at 31° right now... :cool:
Well, I hope someone provides a link to where the statistic (or whatever you wanna call it) that the temperature is 10° too high.
