When you us extreme cooling, the entire card is cold, even with insulation. And people using extreme cooling are killing the cards anyway.
But again, that doesn't change the fact that no where on the box does it say 1.2v is safe. All it says is that you can raise the voltage and get higher clocks, which you can do safely with the stock cooling, and you can do to the extreme with extreme cooling.
So the argument "well it says you can do it on the box" doesn't fly because it doesn't say you can pump 1.2v though the card on the box, and the BIOS limits the voltage to a very safe 1.06v*.
*Again, I'm assuming that ASUS' BIOS had that limit since it the limit nVidia has obviously set for the reference design. If ASUS' BIOS didn't have this limit, then that is ASUS' fault and this particular card deserves the grief it gets for popping, but it still don't make the GTX590 design in general bad.
What I don't get is why give this card a 7 and the HD6990 a 9? So the GTX590 doesn't being anything really new, well what did the HD6990 bring that was new? So you can't overvolt the GTX590 that much, you couldn't overvolt the HD6990 at all. The HD6990 overclocked worse than this card. The HD6990 was louder than this card. The only thing worse about this card really is the higher power draw and the weaker display output configuration, is that worth dropping the score all the way down to a 7?
