Hey, guys after starting to finally mess around with this crossfire setup, I have noticed that GPU 2 is about ten degrees hotter which is odd b/c it has more room to breathe. Short of applying a better thermal compound, what else could I try? btw, I already have a high air flow chassis. Antec 300 with five fans.

You could manually increase the Fan speed of the second card using CCC.
Is the second card older that the first? if so, maybe it has some dust build up around the Fan and heatsink?
