so I dont understand what is wrong......
That lead me to belive that you were worried about the temperature difference
Either way, hopefully my post cleared up a couple of the differences that can lead to a few degrees difference.
Another thing that just occured to me is the amount of processes running at any one time on your systems. Your system might use slightly more CPU power while idling than his does. Combined with everything else, that could account for the 8 degree difference.
