My 8800GTS Runs Hotttt In Sli - At 100% Fan Speeds - Any Help?

Hi Guys, I have 8800GTS 512mb in Sli. They use to run at 55C and like 63C max - 65C max. And Now they are getting really really hot, and I mean at 100% fan speeds. When I play Left 4 Dead, My top card will hit 86C and my 2nd card will hit lets say 74C. Why is it so much of a change? I just cleaned my case out completly - Coolermaster 690. And When They Idle its like 63-65C. Before when I first got em they would idle at 53C or less. You guys have any idea what is going on here?

idk how long ago you got those cards but if they are pretty old then i suggest checking for lint on the heat sinks of those cards. my 8800gt was hitting 98C. I took my 8800 apart and found lint all over the heat sink and fan. I then re-applied arctic silver 5 and...
back to 55C(idle) 68C(load).

but then again i dont know about the 8800GTS layout.

dont forget cotton swabs, isopro-somethin' alcohol, grounding the card to avoid electrostatic shock etc...

Puhlleeese try to not be such an a$$. You are starting to rank right up there with staram5.

Ahhhh nooooo....i should go to work instead...

buy new VGA cooler warrenty would be void if you take the thing apart anyways.. and it may offer better cooling than stock, easy to fit also just rember to clean all the tim off and apply new tim

Before you start undoing screws a word of caution: use a good quality screwdriver that fits well and be very careful no to let it slip. And yes, the correct term is torque but as long as you do not have forearms like Popeye it is unlikely you will overtighten them.
You will also need: A tube of new thermal grease, some paper towels, some pure alcohol or cleaning fluid and a box to hold those tiny, tiny, easily lost screws.
They usually come apart easily enough but start from the fan side, there may be screws under the heatsink cover. Take off the (usually) 4 screws on the back last, these actually hold the heatsink to the GPU core itself and should be tightened carefully a turn or so at a time diagonally, when you come to reassemble.
The old thermal grease on the GPU die and heatsink should be removed using the paper towels, moistened with alcohol, do not lose the small thermal pads that are on the memory chips.
Apply a small amount of thermal grease to the GPU die, a thin, even film is plenty, and put a small drop onto each memory chip as well.

It will probley help out on my heating bill as well, And probley score me some higher overclocks, thanks a billion.

forgot to add thats on Left4Dead where it would usually run at 80C or more, and im oced at 777, 1941, 1050.. woot woot woot.

That's one of the plus points with the Zalman VF900 coolers I'm using, the open design makes cleaning them a cinch, hope your temps stay nice and low mate.
