Heat problems with 8800GTS...

My 8800GTS is getting very hot... close to 80c at full load/idle around 60c. I have tried all sorts of fan arrangements and nothing has really had a significant impact on my heat dissipation. Currently my Centurion 534 case (click for info/layout) is laid out like this...

Does anyone have any suggestions for how to lower my temps a little? I think I would have enough room for a HR-03 plus but I don't want to spend $60 on that right away. Thanks.
 
those temps are around what they should be, although i have my 8800 cards running idle at 46ºC, in an open case. the 8800 is a hot card, literally i think the best way is to get an aftermarket cooler, u can try removing your case door and set the fan to 100% load, remove the plastic cover from the heatsink.

those fans below the vid card, are they sucking or blowing?
 
The one on top of the sound card is blowing exhaust out the back of the case. I have 3 open pci slots with the metal things taken out so air can flow. The one to the right of that one is blowing up towards the 8800's fan.

Is there a safe way to take the plastic covering off the heatsink? Because with my fan setup, I could get a air blowing across the metal and out the back which should cool it a lot better.
 
remove the plastic and put both fans, if u can or just one, blowing directly to the vid card´s heatsink, it´s not pretty but it should do the trick
 
Some people have reported issues with the stock fan never spinning up past 60% on auto. Try forcing it to 100% and see how your temps look.
 
Close to 80C at full load? Lucky you. My GTX hits 93C at full load. When I swap cases soon I'll be picking up the HR-03 Plus for sure.
 
80c on an 8800 card is nothing to worry about and most will see that on stock cooling.

Ya, 80 is what my card tops out at with ATITool scanning for artifacts after 10-20 minutes. Don't worry about stuff that is running at spec
 
Yeah, my 8800GTS sli setup used to hit 84c.. Now my temps never exceed 63c. I usually idle right around 50c - 51c.. I added (2) 120mm fans per card and removed the restrictive plastic shroud.. Helped me TREMENDOUSLY!

About two weeks ago, I did a clean install and went with Vista Ultimate x64.. If you look at the right hand corner, Everest Ultimate monitors my temps in real time.. Its a little hard to make out, but my GPU temps are 52c and 51c, respectively.

That sucks to get such high temps, i get 54 idle and 69 load and thats overclocked at 630/2000
 
officermartinez has the same wallpaper I do. Definitely one of the cooler 16:10 wallpapers for someone who likes the color blue.

My 8800GTX sits at around 55, although with a full load it'll go as high as 80. I've never had any stability issues with it, so I've never really cared, though.
If temperature is an issue for it, turning the fan up to 100% all the time will drop the temp 10 degrees by itself. Granted the new Vista drivers disable fan control, but RivaTuner will still do it. That might be easier (and quieter) than installing other fans.
 
I got the HR-03 Plus the other day. My temps never go above 56°C after a few hours of RTBLIB******
 
That's quite an airflow setup! Question though: Why use 4 120mm fans when you're obviously on watercooling? Is it because the wc setup only cools the cpu and just one of the cards?

Thanks.. My setup initially did NOT include a water setup. It was ALL air. Soooo.. When I stepped up to the QX6700, I KNEW everyone complained about temps on the quadcores. After reading and reading and reading review after review after review (hahahaha), I KNEW I would be heavily overclocking the processor. So, I decided to go with watercooling. I also decided that the only thing that I wanted in my water loop was my processor. Since the air cooling side of my setup worked SOOOOO well, I decided to keep it. No sense in buying 2 GPU waterblocks @ $100 each, on two cards that I will be selling after several months. Maybe, when the 8900 series cards come out, I will sell off my 8800GTS cards and I will water cool the 8900's.. But honestly, I am VERY pleased with the air cooling results.. (not to mention, it only cost me about $40 bucks total between the fans and fabricated mounting hardware).

I'm not overclocked but I'm getting just about the same exact same temps as you, though my idle temps are usually a few degrees cooler (but that depends on how hot it is in the room).
 
Make sure the fan on the card is running @ 100% when its in use as well.

My card idles around 50-55c (below 55 @ 60% fan, 55-60 @ 80%, 60+ @ 100%), when gaming it doesn't go much over 60-65 last time I checked.

P180 case with a 120 yate in the front, and the 3 standard fans all @ med settings. Its also sitting next to my P4 old chieftec dragon case on my desk.

What driver are you using to get fan control with RIvatuner in Vista. I'm using the 156.18's and I can't find a way to control my fan. I've taken to underclocking my card to keep the temps down.
 
I haven't tried it with the latest ones, but it worked fine for the last official release.
Lately I've just let the heat crank up. It hasn't given me any issues, so I think these are just built to be hotter (like some ATI cards). Unlike older cards like the 6-7x series, these don't give me any stability issues at all.
It made me feel better to know it was lower, but I didn't notice any issues.
I'll have to re-try RivaTuner when I get home and see if it still works.
 
I had the same idea as you, except I was getting up to 85C, sometimes 87C (It's hot where I live). But I would touch the card and noticed that it's the side facing up that get's extremely hot. So what I did was place a 120mm fan in front of the 8800, where the PCI-E connector connects (the wires get pretty close to the fan). The fan is hovering right above my hard drive. So it's pulling air in from the front in-take fan, and blowing above and belowthe video card. I also removed 2 or 3 of the PCI slot holders, so more hot air blows out, then the air being pushed over the top of the card is getting pulled out from the back exhaust fan. My card used to idle at 75C, now idles at 65C. At full load it can still get up to 80C, but usually is in the mid 70's.

From some of the other comments though, I might try and take off the plastic covering, see what that does.
 
Where can I find that wallpaper? I hope it comes in 1680x1050, looks awesome!

Also, is it better to measure the temps from the GPU1 Diode or just GPU1 in Everest Ultimate?

GPU1: GPU 48c
GPU1: GPU Diode 55c
GPU1: Memory 48c
GPU1: Ambient 45c
GPU2: GPU 44c
GPU2: GPU Diode 55c
GPU2: Memory 44c
GPU2: Ambient 43c
 
Well I took the plastic cover off the card and then attached a 80mm fan over the heatsink super ghetto mod style (bent paper clips). This took me down about 10 degrees C and i'm maxing out atitool artifact scan at around 70C. I might mess around with my other 80mm fan but for now I'm pretty pleased.
