The Heatkiller GPU-X³ 79X0 Radeon HD 7970 Full Coverage Water Block has a unique design helping to keep your card cool. The flat design and top quality materials are the main features of the GPU-X³ series blocks. The water-carrying part is made completely of high grade copper. In addition to the graphics processor, the voltage regulators are cooled as well. In the area of GPU a particularly fine micro structure was built. Together with a small residual soil strength optimum cooling performance is achieved. In all relevant areas of insulating spacers were inserted. These make for easy installation of the cooler.
To keep the flow resistance, and the overall weight down, all channels are running large volume. Due to the existing thread on both sides of the terminal block the block can be installed in series and other configurations.
For ease of installation, all supplied thermal pads are pre-cut.
Block does NOT fit the 7950 reference design.

I wish I saw this before I got the Swiftech Komodo waterblock. The Komodo really sucked, didnt cool well at all, I replaced it with this and now my temps are under control. This thing is absolutely perfect, amazing build quality and looks sexy.
Excellent block

Great build quality and craftsmanship and is packaged very well. Attention to all the little details shows with all of the heatkiller products I''ve used. I won''t use another brand. Period.
The chrome backplates look very nice and are a nice addition.
