Second GPU overheating on a 5970

I picked up a 5970 today and after dropping it into a rig it runs great!  Except for the fact that the second GPU runs about +23C hotter than number one.

Running BAMT, 820/300, getting 379M/hash from both GPUs.  GPU 1 is running at 77.5C and GPU 2 is at 101.5C

Obviously I didn't leave it running at those temps  Shocked

The card is clean and the fan is running properly, even if I run it up to 90% the temps are reported as very high.  I'm thinking maybe they did a bad job applying the thermal compound on the second GPU? Are there any major tricks to removing and re-applying the heatsink compound?  I have both generic "white paste' and silver based CPU paste to use, which would be better in this application?

Anyone ever had a bad thermal sensor on a GPU?  The back of the card measures the same temperature as a properly behaving 5970 with my IR thermometer.

Or, is it just time to return the card and call it a day?

Thanks for any advice,
