Why my evga 8800gts idle at 70, load at 85+?
Stock heatsink, cleaned out the dust from the fan, using antec 900 so ventilation is good and have a wiring job done too

Had this card for almost two years and behaviour was actually like that since I got it

thanks

they are "supposed" to take it. I don't think it is really too hot for these chips. But I do believe nVidia is pushing them a bit too far. My 7950GT usually ran at 90-95 degrees full load with thermal protection kicking in at 130! It died within 2 years. I will never be sure it was these temps that killed it but I suspect it.

AT tested a fanless 8800GT that got over 100. It was supposed to take that aswell but I wonder for how long...

I believe these temps do really shorten the lives of these cards, though.
I have a TNT that still works,
a TNT2 that runs in a friends computer,
a 9700 Pro that I physically killed (would otherwise still be fine),
a Viper 440 that is still fine,
a Ti4400 running at Ti4600 speeds but still OK,
a 9800 Pro that I recently gave away (still fine)
a Ti200 at Ti500 speeds still running smooth.

However, my 6800GT died after barely two years (never OC'd) and my 7950GT is dead too.

So maybe getting an good aftermarket cooler could be a good idea when you want to use it for a long time.

You can also check with GPU-Z if your fan run at the proper speed. nVidia has a huge problem there with fans running at close to idle impervious to rising core temps.

ya i'm really confused as to why the fan speed doesn't adjust accordingly, it should definitely be at 100% for anything over 88 imo. I was running folding and just hit 93! I paid 320 for this, I don't want it to break already!

I'm using eVGA precision tool and already have the fan at max 100. Rivatuner doesn't play nice with 185.85 on Windows 7, and I've used the workaround but precision tool does the same thing without trouble so why not use it.

Even at fan max 100, I'm getting 95+ on folding =o

Like the nVidia panel, EVGA' s precision tool does nothing else then allow you to manually adjust the fan speed. Riva tuner actually looks at the core temp to adjust the fan speed. That's quite a difference :)

This made me believe your fanspeed was not at 100%

If the fan and card are OK, there seems to be no other option than to get a better cooler.

Are those the normal temps for those cards?

I'd be shocked if I was getting that on a windy case.

90C even at 100% fan can't be good for stable operations. I would get another cooler or send it back for RMA.

my evga 8800gt oc did 65C or so at idle and 90+ at load. i modded the fan config and now it maxes out at about 85* and idles at about 55-60* with ~50% fan.

these things run hot, even the g92's. i'd hate to have a g80.

i pulled one apart that was getting hotter with age and the thermal compound was getting crunchy... it was better after cleaning it and putting as5 on it... but those pads for the memory look like they are just crap... and be careful that you don't mess them up, because there's a big gap between the hsf and the mem chips (which is why they use that crap)...

Instant 10C drop in temps, and probably 20C lower load temp.

Sounds like a bad advice when you don't know the case :)

My case took me several years of testing with fans and air intakes. It get's about 5 degrees HOTTER when the case is open.

The jury is still out on this but I believe that nVidia is having some serious issues with fancontrol. On my GTX260 it get's from 40% to 50% when it get's really hot and consequently crashes like a dog...

I had to install Riva Tuner and set up fan profiles to keep temps under control. The same fan control issues may very well have killed my 7950GT but in those days I lived in blissfull ignorance. I seriously believed nVidia would take care of that...
