6950 (unlocked and clocked to a 6970) Temps

Just wondering what typical load temperatures were with automated fan control (i.e. out of the box).

I'm getting 82-84 C during 100% activity gaming, I have actually another 6950 on the way for crossfire however the cards will have to sit right next to each other, I usually when at uni have the fans set to 60% because the noise doesn't bother me and then the card usually is in between 60 and 70C.

Do you foresee any problems? I'm going to use a fan profile so that by the time the cards get to 80 the fan speed will be at 55% increasing to 60% at 85.

If i'm honest anything past 60% is far too loud, when gaming it's usually not an issue due to speakers/case fans/headphones but anything past 60% and I will probably be able to notice it a lot.

I read somewhere that up to 102C is considered 'safe' but it's obviously not ideal, what sort of temps should I be limiting the cards to?

Maybe to reduce temps I should flash back to 6950s? :/
 
Every 10C above 70C reduce longevity of electronic components by 50%. [ref1] [ref2] However given that graphics cards should be upgraded every 18 months to be able to max out settings in most games, 90C would be fine.

If noise is not an issue for you it'll be fine. Centrifuge fans on reference cards are less affected by sticking two cards firmly together, than non reference coolers are. Personally I'm sensitive to noise so I changed my motherboard at all cost.

Are you for real, that is one one best quotes I have heard. But go on please show me the link to the 10 degree degradation over 70 reduction in lifecycle information. Cheers :)

Where'd you come out with this stuff?

Pulled from the same place as the his claim of "1GB cards crippling performance in games at 1920 res"...out of nowhere. Yes 1GB card would suffer losts of a few fps here or there in some games when VRAM usage go slighting over 1GB, but it's hardly crippling. He's so convinced of his own opinion that he refuses to listen to others and would only consider he's right and everyone else is wrong. I don't even know why drunkenmaster even bother spending time trying to talk sense into him...cause clearly he cares about claiming he's right than accepting the truth...

Those temps are fine, I have 2 in crossfire (with the 6970 flash) but there is a fair gap between them so I get about 85C on max on auto fan control.

I have never heard of the every 10C above 70C stuff before, probably because it's not true (where's the proof?). The cards are engineered to have a tolerance up to over 100C. I would never run it at that but I bet you would find most people are getting the same temps as you or there abouts.

In what way? A blank statement that can potentially be misleading without any evidence from a reliable source to back it up? Thought we were all taught as far back as school that "when we make a point, back it up with evidence"?

Yes I think we all know that higher temp and voltage would shorten the lifespan on the cards, but seriously, I don't think people would just take his words for it on his claim of "Every 10C above 70C reduce longevity of electronic components by 50%", and would have doubt where he pull those figures from.

And 80C ish is fine for graphic card. Take the 8800 series for example...they were all around 80C ish under load...and while some of people's 8800 cards bought from 2006~2007 has stopped working (no problem with the GPU itself, and many revived by fixing the soldering using the oven baking method), many still working great even to today (my 8800GTS 320MB included).

I guess the ";)" suggesting sarcasm went way over your head?

Just ask someone doing EE :) Reference from wiki added. I don't bother to quote papers for non-scientists.

Let me guess, you must have been quite unhappy with my post about 1GB video memory? ;) I would say people should read the notes in the OP.
 
My 480 SOC runs at 82c in crysis and 75c in crysis 2 and it has a 3 year garentee

when SLI'ed up with my other 480 (overclocked) it can reach 100c in bench tests so all i can say is im glad i have a 3 year warentee :D

70C is a popular threshold for servers/clusters setup. Ask any IT officer how they manipulate the air conditioner for the room temperature, and by what temperature should the server send alarm?

Surely this depends on the type and quality of the materials used in the components, rather than an IT officers opinion. Obviously you would want to keep temperatures down but to make such a generalization about all graphics cards is misinformation.

This is not one IT officer's opinion, this is a conclusion from empirical modeling. Why do we have traffic rules of speed limit? Why do we not have different speed limit rules for different small cars? I am not seeing any rules that a Vauxhall must drive slower than a Lamborghini.
