nvidia 6800 gt 256 mb overheating

I don't know on that specific mb, companies use different clipping schemes. It shouldn't take any effort though. Make sure the card is pushed fully into the slot before you try to take it out. Also, look in your mb manual for pictures of the clip when the card isn't in. New gfx cards are huge and sometimes the clip is obscured making it difficult to see how it operates.

I don't think adding small fans will help significantly. You have a larger problem on your hands. I think the heatsink came loose, but the only way you can tell is to remove the card, take the heatsink off, and reseat it using as5 or something similar.

If you're not comfortable doing that kind of work you can try contacting EVGA to see if they'll let you rma it. I'm guessing they will since the card shouldn't be getting that hot.

71C ambient! that card isnt likely to below that without better airflow.

Cause or effect? Seems too high to me to be cause, so I'm guessing that this is a side-effect of the overheated GPU heating the local air and another nearby sensor. An ambient temperature like this would have been reported by the OP as "my case is scorching".
 
do you guys think my temp readings are inaccurate as in there's a bug in the temperatures program? If so, is there any way to fix it?
 
I finally was able to take the card out of the slot and I used an air duster to spray the dust out of the fan and surrounding areas. I didn't get all the dust out because it wouldn't come off the fan area, and I couldn't unscrew the plate because I don't have a small enough screw driver for the super tiny screws.

But hey, I managed to bring the temperature down from the 80s and 90s to around 54 C idle. I'm still worried it will blast above 100 C when I play Oblivion though.

What is the ideal temperature for a 6800 GT 256 mb videocard?

That's a good temp for idle. The actual temp depends on a number of factors -- airflow through the case, and your room ambient temperature, so it's not worth worring about a couple of degrees here or there or get exact figures.

My GT OC would normally get mid 60's on the desktop, and in the mid to high 70's immediately after a 3D game (so that would be around the load temperature). I've seen this range reported by others. You seem good to go; the only way to check the load temps will be to try it.
 
my EVGA 6800gt (agp version, non Cu heatsink) idles around 54c and hits load in the 60-70c range (depending on the game).

i have mine oc'd with cool bits and its about a 4-6c increase all around.

just to back up the previous poster!
 
I just tried playing Oblivion and the temps peaked around 75-76 C and I was getting around 20-30 FPS while around people and while walking around in the mountain forests.

by the way, this game looks incredible!

Those temperatures are much more reasonable - in fact, I'd go so far as to call them "good". My own 6800GT hits anywhere between 80C and 90C at full load depending on the game (though it is overclocked to Ultra speeds), and you don't really want to go much higher than that, even though these cards can stand a lot of heat.

If you notice more temperature problems in the future, aside from dust buildup it can be the thermal paste breaking down and turning to crap (as was mentioned above). This exact thing happened to me - I was getting tons of artifacts and even crashes in games, and my load temps would peak as high as about 105°C. I took off the heatsink/fan, cleaned off the GPU and RAM chip surfaces very well, and applied some AS5 then put the heatsink back on. The result was a 15-20C lower load temperature (and about 5-10C lower at idle). 🙂
 
I have an nVidia 6800 Ultra 256MB that recently started to run high temps 109C+ when playing games. Idle was around 67C.

After reading this thread, I pulled the cover off my fan/heatsink on the card and blew out all the dust (quite a bit). Now the temp runs 53C idle and 67C when it use to be 109C. My ambient temp inside the case is 39C, using 2 huge server quality fans on the side of the case and the stock antec fans on the front and back. One small fan is mounted on the side pushing airflow in to help create circulation.

I just wanted to say thanks for the tip. I've blown out the card before, but never removed the cover to "really" clean it out. It's a big difference.

Thanks!

 
I'd be checking to see if the fan has stopped working and I'd also be checking to see if it spins up under load.

By the way, I have a 6800 GT with coolbits hack enabled, and my "Core Slowdown Threshold" is 120 deg. C. Did you set yours to 135?

That temperature is usually dictated by the card's BIOS and many OEM BIOSes change it. Mine is currently set to 115C on my Asus card.
 
6800GT o/c to 420/1100. 54c idle, 70c playing Oblivion for two hours. NVSilencer for the win 🙂.

How do you remove the cover? The screws are so small
