Danger Den is working on a series of waterblocks to keep GeForce GTX 480 graphics cards cool. There will three different models, the all-copper version will be available first for around $140-150, and 1-2 weeks later the company will introduce two nickle-plated variants.
Danger Den thinks that the all copper block will be in the $140-150 price range, so it won't be cheap. Danger Den will also have a nickle plated top with copper base version and then a third water block that is all nickle. Each will cost more because of shipping and nickle plating costs. Danger Den should have the all copper version ready by the end of this week, which is well ahead of the public release of the graphics card.
