If that number is in C
.......I don't know what to say. Except that your ambient temperature might be just ridiculous

If that number if in F
You need a heatsink remount.

On the underside of the card (PCB) are several screws with springs underneath. These screws control the pressure between the cooler and the GPU. On my 6970 a couple of them got loose during shipping. Had the same problem - one card was 20-30C hotter than the other one. After tightening the screws (carefully) both cards have the same temp profiles, except for minor differences resulting from positioning inside the case.
