We can tell that Geforce 9800GX2 is a very hot graphic card, but at the same time it cools a chip to a better temperature than we've seen with 8800GT.
Let me elaborate on this. We’ve seen Geforce 9800 GX2 in action and after a while the card gets hot. From one side you can barely keep your fingers on the card and we would guess that at that particular side the temperature reaches 80 degrees Celsius. We managed to keep our hand for a few seconds on that particular place.
At the same time the chip works at 60 degrees Celsius, which is better than the temperatures we’ve see with 8800GT. The first official reviews will show up on the Tuesday, the 18th , and you will see it for yourself.
