EVGA started offering the Hydro Copper water-block for GeForce GTX 470 as an accessory. Until now the block was available only as part of the EVGA GTX 470 Hydro Copper FTW graphics card, which is priced at $499.99. With the block being sold loose, users with the air-cooled variants of GTX 470 have the option of upgrading to water-cooling. The Hydro Cooper block costs $139.99.

Manufactured by Swiftech, the EVGA Hydro Copper water-block consists of a central portion from which the coolant flows, this part is directly over the GPU and memory, and makes use of 0.6 x 0.6 mm thin copper pin matrix for heat dissipation. The base consists of chrome electro-plated copper. The other two segments are heatsinks which convey heat to the central portion, cooling the VRM areas. Both both 1/2" and 3/8" high-flow fittings are supported.
