8800 ultra SLI aftermarket coolers

If those are still the air coolers, believe it or not, thats pretty normal for those cards. They are some beasts! A GPU processor can see a bit more heat than a normal processor, so unless you go for something other than air, you are waisting the money, really.

Have you simply removed the current coolers and re seat them yourself? Give em a lube and filter! Change the thermal paste and thermal tape, make sure its all on properly and aligned right, and re seal them.

If that doesnt help a bit, then think on wasting more money. Thermal Goo and strips are pretty cheap. When I got my Ultras, they were from a Voodoo "Omen" pre built computer, and had danger den water blocks on it. They hit 88c!

All I did was take em off, re do everything and put them back on, and not I get a max of 75c. (which is somewhat hot for liquid. I thought I would be kewl and use minimal tubing, so it has like 10'' of tubing total, for the whole loop. That made my temps go up 5c, it appears that with the added tubing, the liquid had more time to cool throughout the tubing.)

Live and learn! Cheap ass set up I got long ago!
