VR-Zone has taken a look at the Waterchill GPU and chipset waterblocks from Asetek! Here's a snip:

The blocks have essentially the same principles behind the CPU waterblock we reviewed previously. They both sport a low flow resistance design to keep the flow rates up. The interior of both the GPU and Chipset blocks are identical, with the exterior only differing due to the mounting for the different standards. As for their GPU block, it is one of the most versatile blocks in the market. It's able to be attached to graphics cards as far back as the Geforce2.
