Video card temps hitting really high levels. (109'C)

My system:
CPU: Q6600
RAM: 4GB
Video: 8800GTX 768MB

My heat sink fan: Link (Zalman ZALMAN CNPS9500 92mm)
My PCI slot case fan: Link ( Rosewill RFX-100B 90mm)
My Case: Link (1xmm Side Fan, 1x120mm rear fan)

My Idel Temperatures: Link (Does not show an accurate "load", system wasn't put in stress for the image).

Video Card:
Idel: 77'C (Started at 68'C then moved to 77'C with no activity).
Load: 109'C (Playing a PC game, causes games to studder until the card cools slightly).

I don't know much of anything about temperatures but I can say that 109'C is really hot. I don't know what to do at this point.
 
What are the ambient temps around the case like? Does the case have room to pull in new, cooler air?
 
Its about 19-20'C in the house now. (About 67'F).

I even had the whole side case removed for a while and I didn't notice much difference.
 
Well that PCI slot cooler really isn't necessary with that heat sink + fan. But anyways, you need to re-seat the ZALMAN cooler as its probably not screwed it all the way, steated properly ect. Or, did you use any thermal compound with it? Either of these would cause the high temps you are seeing. There's a slim chance you have a bad card.
And yes, 109C is very hot, your card is thermal throttling and causing it to perform very poorly.

The zalman is on the CPU😉

Is the vid card cooler clean, dust free? fan running? if so I'd take it off and try a fresh application of thermal paste before anything else.
 
Is the rig just now starting to run this way? is there anything that may have changed recently?
 
Doesn't removing the fan etc, on the video card void the warranty?

There have been no new components in months. Nothing that would really prompt this to happen.
 
Get the card out and clean the heatsink. You can do that with a can of compressed air, or just use your lungs to blow air into the fan and heatsink. You can also use a small brush to remove the dust out of the fan.

This. Also make sure the fan is actually spinning.

Of course you could replace the heatsink or remove the old thermal paste and re-apply AS5 or similar if you don't have a warranty. If you do have a warranty however, see if you can RMA.

Also double-check temps with I think it's Rivatuner.
 
My 9800gt from xfx was running at 82idle and up to 95load on the stock cooler they had on it. I think the stock cooler xfx puts on their 9800gt's are hold overs from the 7900gt series because they're alot smaller than the EVGA coolers. Anyhow I bought a zerotherm GX810 cooler (similar to the zalman vf900) it was $5 after $30 rebate at newegg and now my temps are 48idle and 55load. From what I hear it's not advisable to use aftermarket coolers like the zalman vf900 on the GTX type cards because of the higher core and memory temps generated from them, but I don't know from experience as I stick with the gt series myself.

OH and also EVGA states that removing the stock heatsink does not void their warranty which on most of their cards is lifetime I believe. However you should register the card with whatever manufacturer it is and check their policies on heatsink removal.

Good luck
 
That case is pretty poor for airflow. A single 80mm intake on the side (blowing more on the cpu area instead of video card)

I'd experiment a bit with fannage. If you have a spare 120mm fan around (I suppose a 80 would work too, but 120 would be better) try to rig it up somewhere behind your had drive connectors, blowing cool air from the bottom of your case up and onto the bottom of your video card. Reove your expansion slot covers if you can, so the air can flow across the card then out the back. If your temps are still pretty bad (this alone probably won't bring it down enough) you may want to think about buying an aftermarket cooler, or a case with better airflow.
 
What people have said so far is all what I would say, especially the can of compressed air.

I've seen quarter-sized dust bunnies out of an 8800GTS 640, the card temps dropped 5c after that, it was previously at 82c loaded with a ~15% OC. I would also suggest trying out a small (12") box fan pointed at the case with the side panel off. These steps helps rule out inefficiencies like dust buildup and poor case/video card airflow.

A VF900 cooler won't fit on an 8800 GTX, because of the different mounting holes and because it will probably not be able to keep up with the heat output.
