XFX is the only manufacturer to offer warranty on the 6990 OC mode, but shall any other part of the system that got killed due to OC, you are screwed as the act of OC and running things off spec voids warranties. If you are still arguing, than don't even think of overclocking. There is a gap between default and spec, and OC lays inside this zone. Fail to understand or see this zone means you are likely to kill your PC. Consider yourself LUCKY if the video card is the only thing that got killed. I personally have seen PSU breathing fire, funny color smokes, resistor popping out of the circuit like a rocket, etc etc.
Round up:
Some believe that VRM used on 590 is problematic. This theory was supported by, a) hot temp, b)Nvidia cheated by reporting the temp of cores, and c)590 dies upon improper OC.
Well, the first 2 claims was clearly busted, although some may still believe other wise after a clear example of the existence of a HDD fan when the IR graph of 6990 was taken.
Thanks guys for the cliffs. But it's still unclear what is trying to be proven, or disproven? If anything? Or are these discussions just speculative and interesting to some? Please, nobody read into this too much, I'm only just curious.

AtenRa is trying to prove there is an "extra" fan being used at the front in the 6990 system in which the thermal images were taken. Pretty much everyone has shown that the cooler temperature is explained by the different coolers used on the cards, and that his use of Bernoulli's principle in this case is flawed.
Different coolers? Isn't the difference in the type of air mover used? AMD uses a blower and Nvidia uses an impeller. Both designs utilize two separate vapor chambers on either side of the fan. IMHO, you couldn't have a more similar cooling solution even if you planned it to be beside the actual air mover used.

Yeah, I didn't read the last few pages either. So what's the subject of the conversation guys? It's kind of a blur.
WHAT!? 590 dieing on reviewers/users!? non-sense,.. they must have used wrong drivers (ones that came with the card in the retail box!) and overclocked their cards! its their own fault, they shouldnt have overclocked them in the first place!
*sweeps a 590 under the rug, while whistling innocently*
I am not sure, looks like the "feeding frenzy" died out since that techreport debunked all the FUD.
The one thing they didn't address was the 2 instances of people claiming to have had a card blow up on them without OC.
But with all the false info presented before that... who knows.
No, I said feeding frenzy because dozens of users came in one after another to voice every increasing displeasure. With new users being stoked into ever greater crescendo of outrage by the posts and claims of their predecessors.I'd say it was more the week vacation the more vocal poster got that diffused the "feeding frenzy."
Not every single poster was part of the frenzy.Some of the arguements used on the subject have been very interesting and based in good science. Both IDC and that PM user (PM81?) have degrees in engineering and their input, while speculative, has more weight than random forum guys and misused factual science.
Yes, even if a stock GTX590 isn't going to explode, I will not be recommending it to people. I am concerned about the long term reliability of a card this close to the edge (... amusingly, nvidia has a history of redlining cards and making cards that fail in large numbers)The GTX 590 has issues, what the issues are might not be known. I think the 3560 RRoD fiasco was a good comparative. Let's just hope it isn't that bad.
For the mean time, I will continue to provoke my girlfriend with "OMG your nvidia is going to blow up!" haha.

Im sorry if some of you cant understand it but when one GPU chip or any chip consumes more power it will generate more heat. That heat will not magically disappear in thin air, it will be transferred through the heatsink and the fan outside of the card and in HD6990 case, the right GPU chip (the one next to the 8-pins 12V) will exhaust that heat inside the case.
Because the HD6990 @ 450W produces more heat than the default GTX590, the front side of the PC case where the HD6990 exhaust all that heat it had to have a higher temperature than the GTX590.
I will ask you people to see the bellow pictures and tell me why the HD6990 has a temperature (color) variation (Arrows) at the two edges. Dont forget that the heatsink is at exactly that spot and the temperature at the end of the card (after the 8-pins) is much lower than the temperature in the other side of the card (back panel).
Dont forget that the card extent beyond the metal for the HDDs (Blue color) and goes half way below the HHD. You know what I believe, do you guys have a different explanation??

Ofcourse the fans on the radeon is moving more air, it consumes more energy but still keeps the card cooler. The radeon card just have to put a tiny little more air out of the case vs the nvidia card to keep the case temp lower then nvidia.
Note that these pictures using a scale suited to the comparison of a wide range of graphics cards but smooth results beyond 80 ° C. Voici le même cliché mais avec une échelle différente qui permet de mieux représenter les différences entre les hautes températures : Here's the same shot but with a different scale to better represent the differences between the high temperatures:
