heating issues on the 8800GTX?

[pentium]

I was looking through another forum where somebody was wondering if his video card was overheating as it was giving a temp of 82 degrees. I thought that was pretty hot until another member added that the regular running temp for his 8800GTX is around 80-95C!

Did I miss something since the days of the Radeon 9600? I was always told that video cards did not like to run hotter than 70 degrees and yet here are members that report no problems with more modern cards running almost hot enough to boil water.
Look for yourself

sounds like they are made this way.
by the time it dies from the heat nobody will care about it anymore?

i think most if not all current nvidia cards warn if power or temp out of range and go to low performance mode. nvidia are well aware that many of their customers are retards

Nice way to put it ey

It's the normal temp of these cards, got a 8800GTS 512MB, it runs ca 85-90°C in open air... The fan does not speed up to full throttle...

Guess their customers want silence... If you want better coolers there are many to choose from;

Note, my card is the G92 version, 65nm instead of 90nm
It still has a power consumption of max 145w tho just like the GTX, 175w for the Ultra, so it's no wonder they get hot... Remember that we now have ca 700 million transistors on our GFX cards, compared to ca 600 million for the most highend quad core processors, where most of them are only used for L2/L3 cache and are cooled by giant copper heatsinks

My NVidia 7300 has a slowdown temperature of 150°C

That's the slowdown temperature, not the shutdown temperature!

Normally though, it crawls along at about 50°C, which to me seems hot, but I guess I'm just getting out of touch with modern heat limits.

Most people report video corruption way before that!

Thus, IMO, they raised the heat rating so that people don't panic! LOL!

Per is rigth: most people wants a silent sistem, ignoring that heat can kill their hardware in a few months. Graphic cards, cpu heat spreads, psus, hard disks: everything should be noiseless and boast high performance; this trend is affecting notebooks too.

If I were you, I'd set fans to an high rotation: if the driver panel doesn't allow to, you should install Rivatuner or nTune. I can't give you more information because my last (and only) nVidia chip burnt form overheating about 2 years ago. This is a really sad story.

I've got a 640M 8800GTS in a microATX case, it idles around 50 C and goes up to around 85 C under full load.

Mine's been BIOS modded by me to run at 648 core, 1512 shader, and 1020 on the memory though. I also lowered the "critical" temperature in the BIOS from 110 C to 90 C, that way if it gets a bit hotter, it'll throttle the fan up more..

Although that's also the temperature that makes the chip throttle back, IIRC.

I have to say the 8800 series is much quieter than the ATI X1950 series, fanwise anyway...

Modded bioses void the warranty, don't they?

I don't think they do.. My card is an EVGA, and IIRC, there's nothing in their warranty policy about BIOS mods.. I may be wrong though.. I mean, they do sell factory overclocked ones.. Mine's still got its factory heatsink and fan, and modding the BIOS on an nvidia card is very easy.. I also saved a backup copy of the original BIOS in case it messed up.. Otherwise i'd have to run atitool to apply the o/c every time.. If overclocking the card voids the warranty, then i'd say it's voided anyway.. Whether you use ATItool or a bios mod to do so..

Re: heating issues on the 8800GTX?

I have a dead Chaintech GeForce 6600GT in my hands right now. It is 100% dead. The fan does not spin when system power is applied... I don't know if the fan quit, and it died, or if the fan control circuit on the card is dead. It does not get hot at all, and I see no signs of heat damage or scorched parts. Just plain ol' dead.

It has two Skywell SEL caps, 16v/330uF that are not bulged. Remainder are Sanyo good grade caps.

I've read numerous user comments on Newegg about prospective cards. There is a very high number of comments about severe high temperatures. Evidently the passive HS types run terribly hot. These cheesy little fans do not inspire confidence, but I guess they have to do. Does anybody know if a good nVidia card comes with monitoring software for the card temps?

Re: heating issues on the 8800GTX?

@ gg1978: both overclocking and bios modding void manifacturer's warranty because you use the card outside its operating ranges. Even an heat sink replacement voids too, so I think is far better spinning card's fans at an high rotation than overheating it by running stock: it doesn't void anything and it should be effective though noisier.

@ bgavin: mine was a mobile 5700. It was always running hot, around 70 °C in idle and a lot more while gaming; the shutdown temperature was around 115 °C and it newer did.
The cpu was a desktop Athlon 64 3000+ and they shared a small heat pipe, cooled by a slow rotating, bios controlled fan: the notebook lasted about 4 months, then the screen became red and green striped, nVidia drivers refused to load forcing me to use the Generic vga ones and, at last, the computer didn't manage to boot. Tecnical assistance replaced the graphic chip and, learning from this experience, I tried to cool the notebook in a few ways, like lying on eraser-made grommets in order to help dissipation and using a desk fan at home. Two months later it broke again.
Maybe Rivatuner can monitor die's temps, since all latest nVidia have a thermal diode inside.

Heat is a real electronic killer: keep it as away as you can.
