8800GTS too hot.

My 8800GTS 320MB is running at 70C idle and 108C loaded with furmark. I heard this card runs hot but I didn't expect this hot. I am guessing these temps are unsafe?

I am using a Sonata 2 case with a 120mm 1200RPM intake fan right next to the card blowing directly on to it and the same fan on exhaust. The wiring is clean enough to not obstruct any airflow either so I can't image a much better condition (within reason) for running this video card.
 
Dusted it lately? Canned air will do wonders for a tightly-finned heatsink.
 
Just changed two thing:
- Cleaned out the dust with can of air
- There was a NIC in the slot right under the video card so I moved it down one slot to give it more breathing room.

Now it runs at 100-101C under load. Made a difference but still high temps..

How's the airflow coming out the back of the card during load? Do you feel a gush of air coming out? What's your fan speed % under full load as well?
 
just curious, would a fan that is blowing in directly beside the fan make it worse? i.e. making so that its pushing the air down onto the mobo and not let your GTS' fan have enough air to pull?

as K6 said, check fan speeds too.
 
Temps are quite high, yeah.
My 8800GTS maxes at like 75C, which is fine for this card.
I've tested my G80 to see how hot they can get without problems. I turned down the fan speed down to like 15% and it shot up at 120C on load with Crysis.
No artifacts until 125 C =P
 
101c, that's crazy. The Antec Sonata does not have good air flow. You can also try an aftermarket gpu cooler though, probably your best bet.
 
Get EVGA Tuner and set the fan to a manual speed. Also Furmark Stress the card worse then any game ever will.
 
that is one beautiful after market cooler. thanks.

i have the same issue (same card) as the OP but mine tanked at around 62c under load, lol.

it booted at around 42 but quickly climbs (while idle) to 54.

Cooling probably isn't your issue then. Are you overclocking? Have you tried a clean driver install?

Has anyone ever heard of Riva tuner? You can crank the fan on the 8800gts 320mb all the way and lower those temps to like 55C.

That's what I'm hoping the OP will try. The stock 8800GTS heatsink is pretty beefy and more than capable of cooling the card. It's most likely a fan issue.
 
Thanks for the replies

I have the case side panel open and the video card fan set to max now (using rivatuner) to see what my idle temp would settle to. In theory the case and airflow wouldn't be a factor doing this so I can do a sanity check on the temps my card is reporting.

FYI I haven't overclocked it.

I had the heater on all day today so my ambient temps are high at the moment. My card was idling at 78C just earlier :eek:
Room needs to cool down a bit too.

As for an after market HSF the card is fairly dated now so I am hoping I don't have to put money into it to keep it functioning. I think I'd be better off putting my money towards a newer card. I am using it because I have it.

I'll get back with temps after I leave it running for a while


Edit:

I left the machine running idle for a few hours. Open case, max fan speed.
Temps don't seem to drop below 66C. I guess its just the limitation of the stock HSF?
 
Those are pretty high temp. Are you sure the heatsink is attach properly to the card? Reseating it with AS5 wouldn't hurt. my 8800gts doesn't get higher than 70C load and idle at 55C.
 
Something aint right with thoose temps, my old gts 640mb did like 80c or so after i dusted it out and it was heavy overclocked to with fan on 70% or so.. its crazy that it should load on 100c.. thats nuts.

Yep.

When I had my 8800gts 640mb. I OCed it as far as it could go with stock cooler, and the temperatures would never breach 75c. idle would be in the 40's and 50's

I think the OP's card is dieing. Time for a new one :D
 
Just try to reseat the HSF assy. Some manufacturers can do a very poor job of TIM and heatsink installation. Clean the old TIM and apply some new, quality, TIM and make sure you have good heatsink contact. I bet that will drop your temps a good deal.
 
Forgot to add, if it currently has thermal tape instead of TIM, this could be a problem as some tape is quite thick and a layer of TIM won't be good enough to make contact.
 
hey. your problem is that the stock thermal compound between the HSF and the core is breaking down and needs to be re applied.

My 8800GTX, even when overclocked, gets to 92C MAX in furmark. it gets no hotter.

Oh, and to all saying the stock cooler is crap. stop. the 8800GTS/GTX coolers are some of the best coolers for the GPU. the after market heatsinks don't chop more than 10 C off, thus its not worth the price, especially considering these cards aren't manufactured anymore.

That's what I'm thinking too. My 8800GTS rarely even hits 70C even under full load and idles in the mid-50's. Not having the card drop below 66C isn't good. Either the OP has alot of dust in the stock cooler or it needs to be reseated. Hell, 66C is warm for my card while gaming, lol.
 
My g80 gts doesn't crack 85. I would do like thechosenx said and reseat your card with new thermal compound.

Edit: Also check your fan speeds. Check to make sure that the fan isnt breaking down and running gimp.
 
i was having problems with hitting 95c load on furmark, when i'd normally hit nothing over 85c. I reseated the heatsink and now even if my card is overclocked at 8800 Ultra levels, i dont go over 92c
 
Try to see if removing the side panel while running the PC changes anything. You could have a negative pressure problem inside the case. If you run alot of fans 'sucking out' of the case, your other fans could be generating more suction than the GPU, working against it (sort of like flying an airplane at 100mph in a 100mph wind... you go nowhere). You might want to try a positive pressure fan system (all fans blow in except for PSU and GPU).
