I'm running two Leadtek 6800 GTs under a load of Firefox and miscellaneous programs the first one is running at about 74/57 and the second card is running at 71/56. They're performance overclocked to 400/1100. When I'm gaming I've seen the cards get up to 90 degrees.

The temperature inside my case stays around 30 degrees and I've jerry-rigged a desktop fan to blow onto the cards. With the fan on I can get the cards down to about 60/40 idle. I'm running 77.30s and I'm looking for any solutions to dropping my temps (aside from the extra fan).

Put Zalman VF700CU or AC NV6s on them.. that would bring the temp down and also lower the noise.. Should fit SLI too I think..
Viods the warranty tho..

Dropped my Max Load temp from 90ish to about 53c with a Zalman..

EDIT
a bit related, quieting down SLI article using NV6s..

Truthfully, what effect did that have on performance & overclocking?

Didnt do much benchmarking, I couldnt OC at all with Gigabytes stock cooler (that crappy Heatpipething) without going over 100C which I wasnt comfortable with..
Didnt really explore how high I could go with the Zalman cooler, but the "Auto clocking" feature in Forceware set the card to 420 from 350.
I set it myself to 410/1100 and kept it there, GPU stayed around 53C at full load..
If felt "smoother" at stock speeds too, either that was a placebo effect, or the card was throttling due to high temp with stock cooler..

made a thread about it when I bought it, here:

EDIT
btw Im not really a OCer, I just upped it a bit cause I could and the temp was low enough..
Reason I got the cooler was cause I was worried about that 90c load temp, a pleasant side effect was that the Zalman was completly silent in my case, which the Gigabyte cooler was NOT.
