Could anyone tell me why if I have a weird chip?

It's a E0 Q9550 OC'ed to 3.825GHz on 1.3125V on a 780i FTW and my temps don't look right

Basically at idle temps, it's at 31/31/39/37 while at full load on Prime95 the highest they go sometimes during high ambient temperature is like 49/49/47/48



Sorry for the uncropping of the image
