HEATKILLER® GPU-X³ GTX 680 LT 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 memory modules and voltage regulators are cooled. In the area of GPU a particularly fine micro structure was built. Together with a small residual strength a optimal 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.

These are great waterblocks, and easy to install. I bought 2 of them for my GTX670 FTW cards (they use the 680 pcb) and now under a 20 minute stress test they barely clear 40C. I used the included thermal pads on the components, and arctic silver v on the GPU
