If anything the GeForce GTX 470 and 480 can use cool cooling, what better option then to go with liquid cooling ?
As such eVGA released their Hydro Copper waterblock, the cooling solution was created in collaboration with Swiftech and is compatible with the GeForce GTX 470. It is composed of a base plate of chrome plated electrolytic C100 copper, a 0.6 x 0.6 mm thin pin matrix, an integrated heatpipe that connects to the power mosfet heatsink and, of course, high-flow fittings for 1/2-inch and 3/8-inch sizes. The entire mechanism is built in such a way so as to take on the heat from not just the GPU, but also the I/O chips, VREG area and the memory.
The EVGA Hydro Copper Waterblock is quite noteworthy through the fact that it is compatible with 2-way, 3-way and 4-way SLI setups. Those interested will be able to acquire it for $139.99.
