Danger Den is busy preparing its upcoming range of water blocks for the GTX 480. The new water blocks will cover all the vital cooling areas, such as the GPU, memory chips and the VRMs for maximum overclocking potential. The GTX 480 water block will be available in three variants: all-copper, a nickel top and copper base and all-nickel. All models will include a mirror-finish, and are expected to retail between $140 and $150. The all-copper version will be available by the end of this week, which means that it will be available well ahead of the GTX 480 release. The remaining models will be available at a later date.
