Danger Den started shipping a waterblock for NVIDIA's GeForce GTX 580. The company claims this waterblock can keep the card at 37°C in Furmark (with ambient temperature of 18°C). You can find the specifications over here.
Danger Den, working closely with Nvidia , has immediate availability of the DD-GTX580 block to liquid cool the world’s fastest DirectX 11 GPU. The DD-GTX580 block is a single slot solution* cooling all of the major heat components including the GPU, RAM, power mofsets, and more.
The DD-GTX580 block continues the trend to provide superior cooling performance (30-50C drop from stock cooler) while minimizing the pressure loss across the block. This combined with other Danger Den blocks in a single loop allows a high flow rate thus maximizing the cooling performance of all the components.
Danger Den, based in Astoria, OR, will have the DD-GTX580 available in the same finishes as the GTX-480. Available immediately is the satin finish and the mirror black chrome with copper base. Other variants will follow in 1-2 weeks. The product page lists all of the details and any questions can be answered in the Danger Den Forums or support page. Be sure to check out the Gallery of photos (more coming soon).
Please note, there are other GPU blocks in the works to be released soon ;-)
*single slot requires a bracket or modification of the original bracket.
