Asetek has created a watercooling solution for NVIDIA's GeForce GTX 580.
The video shows a reference GTX 580 card branded by PNY. The cooler could be to be a pre-assembled GPU water block loop that replaces the aluminum channel heatsink in the reference NVIDIA cooler. The NVIDIA reference blower is retained to cool other components such as memory and VRM, probably at low speeds.
Asetek put its GTX 580 prototype to test, by overclocking the PNY GTX 580 Enthusiast Edition to 995 MHz core, 1846 MHz CUDA cores, and 1100 MHz (4.40 GHz effective) memory. At these speeds, the GPU was able to score 1285 points at average framerate of 51 FPS in Unigine Heaven 2.0 benchmark says TPU.
It would have been clever from Asetek to NOT use Furmark in the video, as dedicated hardware and software detect the stress application and will clock down the graphics core once detected and at certain power signatures.
