Thermaltake announced that Thermaltake made the first water cooling unit for the R600 from ATi.
The design of Thermaltake Water Cooler is height, looks like still requires memory cooling, and bigger than 88GTX.

The performance still could not be said good, because R600 personally was not yet launched.  But according to me, watercooling R600 edition this apparently was good enough, only heard the rumours news that The Cooling still needed memory cooler and will make hard for users to put on the ramsink saw the dimension of the quite big cooler. May this not happen and thermaltake could inform the further specification
