NVIDIA is just a couple of days away from releasing the GeForce GTX 580, the company's trump card which came literally out of nowhere, compared to AMD's Northern Island GPUs, which were talked about for months. At the PDXLAN 16.5 event, NVIDIA showed off some slides that are most relevant to gamers, notably the thermal and acoustic characteristics of the reference design thermal solution. The latest thermal solution does look a lot more compact compared to that of the GTX 480, especially the lack of that hot-plate and heat pipes sticking out is notable.
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.
