has scored a picture of a watercooled version of an MSI Radeon HD 2900XT card. It has a very large heatsink with a two part watercooler attached to it.
The pump is fitted to the card itself and is powered from the normal fan connector. There are two separate cooling elements on the card, one for the GPU and one for what appears to the the power regulation.
The radiator is using a 120mm fan, although we're curious about where you're going to stick it.
