GeForce GTX 580 Cooling Solution Detailed to Public
 

The new cooling solution relies on vapor-chamber technology to convey heat to the aluminum fins, instead of heat pipes. The fan features a more refined adaptive fan profile. Combined with a more power optimized GPU, the new thermal solution is said to be more efficient and quiet compared to even that of the GeForce GTX 285.

Saw a screenshot at expreview where they have shown the GTX 580 idling at 30 degrees Celsius. Wondering if that was with the stock cooling solution or something 3rd party.

if the GPU shuts down all none-active units, it may even idle lower, as long as the power draw is similarly low ;)
