Already providing a waterblock for the Radeon HD 5870, Danger Den is hard at work on a solution for another high-end AMD card, the one codenamed Hemlock. Seen below is the all-copper block for the dual-Cypress GPU card which is expected to debut in November as either the Radeon HD 5870 X2 or HD 5970.

Danger Deng's block will cool both 40nm Cypress chips, the PCI-Express bridge chip between them, as well as the voltage regs and GDDR5 VRAM, and should enable higher overclocking, if the card can handle it, of course. The Hemlock DD waterblock will hit stores a few weeks after AMD releases the dual-GPU card.
