Info below from the Hexus preview

Dude I think you need to look at the preview in the above link.

A real-world assessment
Examining the whole noise/heat/power issue in more detail and taking a real-world game into account, we played through Battlefield: Bad Company 2 and noted where system-wide power-draw was highest. The game works the CPU's cores and gives the GPU(s) a good going over. We then left the card rendering the high power-draw scene for 10 minutes and logged the maximum temperature, fan-speed, and power-draw.

The observations were noted with the card(s) installed inside a Corsair Obsidian 800D chassis with side panels on. The table below highlights our findings and provides a subjective analysis of the fan noise.

GPU Power-draw (maximum) Temperature
(maximum) Quietness /10
(higher is better)
CoolIT GTX 480 OC 1.5GB 410W 73C 7
GeForce GTX 480 1.5GB 419W 94C 4/2
GeForce GTX 470 1.2GB 354W 94C 5/3
Radeon HD 5970 TOXIC 4GB 488W 64C 6.5
Radeon HD 5970 2GB 366W 77C 5
Radeon HD 5870 TOXIC 2GB 324W 66C 7
Radeon HD 5870 1GB 288W 76C 6
Radeon HD 5850 1GB 260W 63C 7


Let's explain the table. The noise perception is a subjective rating out of ten for the quietness of the card when under gaming load. Simple rpm doesn't always tell the full story.

During our session of Battlefield: Bad Company 2, the temperature of our OMNI-cooled GTX 480 rose to 73C - a massive 20C less than NVIDIA's reference design.

Furthermore, the cooler remains remarkably quiet. With the radiator fan spinning at a moderate speed, it is barely audible and quieter than most of the comparison air-cooled cards.
