I have a pair of 8800 GT cards (in SLI mode) They tend to idle at between 60-68c Under load (Crysis on high) they go up to 88c Are those temperatures safe?
well I am using a single 8800GT card, so I am not too sure about Dual, I know mine idles at 50-52 C and Loads at somewhere in the 70's
Hi And Welcome Those temps are on the edge of high....is worth downloading RivaTuner and increasing your fan speed to bring em down (nvidia's fan speeds are set to 29% for some stoopid reason)
I've done that and set the minimum fan speed to 50%. Now one card is 58 and the other is 53. Is that better or should I increase the speed more?
It totally depends on your ambient temps, case airflow and particular card. 8800gt are really hot cards, not abnormal at all, only way down is pump up fan (not extremely efficient) or aftermarket cooler. They can cope with 90ºC, though
Oh, that's good to know. (My house is hot as hell, so no help on the ambiance) I've never seen it go above 87 ever (Crysis on max settings) so I guess I'm safe, especially since I can get them lower now. (I also have them underclocked to 600mhz (they were factory over clocked to 625))
why worry? i have a gpu of 8400 series gforce 512mb gs pci express card mine loaded up to 90 degrees andwas a little worried but i got pci fan now to blow out hot air from under neath the card now i have idle of 49 celc and underload no more than 65 this is good and anything up to 100 is fine stop worring the shee rpower of these cards are designed to withstand heat let me tell you then can go up to 130 b 4 they fry ;-) if you are worried get complete airflow to your pc

I'm not worried about that. My CPU temp never got to high, and I don't have any other cards installed, so the only thing in that area is the GPUs. (Motherboard temp is always fine too)
Hi Guys thats why i opted for the 8800 gts (g92) because the cooling is significantly better - the fan on these models is very effective. using rivatuner to set the fan speed to 60% at stock settings it idles at 37 and underload 52 - thats quite impressive with those temps i think i might overclock a little and see what this card can do. also benchmarked the card and i got 13,600 points. regs paul
No, they will throttle before they get to a dangerous temp, and even if they didnt, at around 105-120 they will cut off to prevent damage
Use Rivatuner to set fan profiles that rise with the temperature, it works great & my temps never exceed 60c when playing Crysis for example but its completely silent at idle, I also added two hotkeys for instant 100% or 45%. read this: http://www.vaguesoft.com/users/dwood/blog/tutorials/rivatuner/#control
Always thought that 8800GTs high limit is 85C but if your worked till 88C I feel better. Mine idles at 60C and under load gets to 78C max. Thats @ 100% fan under load and 50% in idle.
Mine is overclocked, but stays at 54C idle, 72C load. But my one got metal shroud instead of plastice and the heatsink fins are altered for better cooling.
I just turn my fan speed up to 100% when I'm gaming, I use headphones so the noise doesn't matter. And then turn it down to 40% when I'm not so the noise doesn't annoy the hell out of me.
