Hey all,

Just got my rig working after a PSU failure and I'v notied that after 45 mins of running Tomb Raider Anniversary as a stability test, I ran HW Monitor to check GPU temps just in time to see both my 8800GT cards drop down from 101 degrees!

Is this normal!? It seems hugely high!

Any suggestions or reccomendations for cooling? They are the Palit +1 GB model with the stock heatsinks and fans.

Here's a rig rundown too:

MOBO: Foxconn Renaissance
CPU: Core I7 920
HDD: 2x 7200 rpm
PSU: 750w HighPower SLI ready
GPU: 2x 8800GT +1 GB

Thanks!

James

That is rather toasty, I have Zalmen VF900's on my GT's and they rarely get above 60c under load. The thermal limit is 105c for the 8800GT by the way.

hmmm I can't see any way to get the heatsinks off of these to change them :( 

would installing an 80mm fan in the middle of the case (ie not exposed to the outside at all) blowing across the cards to the back of the case help at all?

DId u change your PSU with the new one after failure?
U can try clean the card and re-apply the thermal paste first...

Undo all the screws that you can see in the lower picture then gently twist off the HSF, warm it up with a hair dryer if need be.

As a bonus question mine still have those stickers all over like with barcodes and stuff, should I get rid of them?

They will have zero affect on the cards temps.

ok, will the mountings on the cooler you mentioned fit?

Yes, it just uses the four mounting holes around the GPU.

Also install more case fans into your computer case (get as large fans as possible, and max out all your fan spaces) - the 8800GT model is the type that dumps heat back into the case so more fans would help a lot.

You can also try this and you won't have to install a fan or touch your GPU heatsink.

First get Real Temp .0 so you can monitor your temps while you game (have the program write to a log file every 5 seconds.

Second, get EVGA precision and manually raise your GPU fan RPM to 90% right before you start gaming. It'll get a little noisy so use headphones.

Then come back and tell us if that helps your temp problems.
