Are the two cards right next to each other? If so, you can't really do anything about it. My suggestion is get a big house fan and blow the whole computer with the panel removed. That lowered my 6990 temp by about 10C.

Running my unlocked shader 6950s right now at core 900/mem 500 in an open case at 61C and 64C @ ~66% fan speed.  Only additional cooling is two 120mm fans sitting on top of the two cards.

Both of my cards are the MSI reference 6950s

Also, what do you have your fan speeds set to?

You've tried manually setting your fan speed right?

DISPLAY=:0 aticonfig --pplib-cmd "set fanspeed 0 80"
DISPLAY=:0.1 aticonfig --pplib-cmd "set fanspeed 0 80"
etc.

That sets it to 80%

Set it to 100% if you have to, your card is gonna fry at that temperature.

Have you underclocked the memory? That will should help.

I recently changed all of my 58xx series cards to run at 305 memory and the temperature dropped significantly.

You can install the fans off a molex rail, just cut the ends off one and splice your fans on with a wire nut, set them to blow into the gap between the cards.
