The Heatkiller GPU-X³ 69X0 Full Coverage Water Block has a unique design helping 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 Rambausteine ​​and voltage regulators are cooled. 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 many opportunities of integration are given in the cooling circuit.

For ease of installation, all supplied thermal pads are pre-cut.

First off... went from 115 peak on a pair of early 6950''s to 42 if I let it sit long enough (everything''s on a single loop so my I7 960 adds a few degrees). You can turn your cards up to max clocks and minimum voltage in catalyst and still sit perfectly stable. Only problem is the weight. Had to switch off to a lay-down sever chasis to keep from breaking the pcb, but I''ve got the room to spare.
