Hey guys,

I own a Geforce 8800GTS 640MB card and was wondering how hot is too hot.


I downloaded speedfan to monitor my temp and while playing the new crysis demo the temp went up to 99C.

My resting temp is around 70C

Is this too hot for my GPU?

I have increased the fan to max speed. Would this still leave my card in the danger zone?

Cheers.

this might be of use.

GPU's can get quite hot, especially with very intense games like crysis.
You might want to look into a newer card if you're finding it a bit too hot or slow, or some additional fans in your case.

In a word, Yes.

the 640MB 8800GTS was the G80 core, so I'd suggest you want to look at around 75*C as your load tempt, and somewhere under 60*C for idle.

That said, I believe the actual thermal ceiling for the core is about 108*C.

My 8600GT reached 99 degrees only on Furmark, and it has a passive cooler (no fan)

In crysis it would reach about 76 or so.

Obviously the 8800GTS is a faster card but maybe your case has bad airflow or something...

I just read that someone got a reply from Nvidia saying that 145C is the max temp for the card and that being around 100C is safe but no recommended.

Does this sound right to you guys ?

I'd say your PC would probably crash by then. Investigate airflow and clean out heatsinks / fans etc :)

145*C may well be the maximum temperature the core can handle, but I would suggest getting anywhere near that will cause instability & crashes and reduce the life of the component. I'd really look to lower that load temp if possible, even by just 10*C.

99 degrees for a G80 is definitely not a temp you should see under normal conditions, even though the G80 is a hot chip.

I would say it must be because of dust build up in the heatsink which you could blow or suck away using a blower or a vacuum respectively lol.

Or a case with bad cooling\airflow...
