It is something to do with temperatures.
CPU 46 MB 31 GPU 55 3dmark06 = 8296
CPU 51 MB 39 GPU 52 3dmark06 = 2082
All those 'higher' temps are well within the normal operating temperatures.
82096 is a bit low, but 2082 is VERY low. My system usually get 10,000 to 11,500 according to the 3dmark benchmark website.
I get the lower temp by taking off the side of the case and having big floor fan blow on the computer.
