Using X800 GT and X800 GTO based cards, Tul is taking PowerColor Radeons and adding a Thermaltake
water cooling solution. Dubbed 'TideWater', it is similar to other water coolers with a standard water block for the GPU and a slow-spinning small fan to keep the block cooled. It includes a pump, radiator and all the others things a water cooler needs, but has been scaled down considerably to fit comfortably inside the chassis completely... at the cost of a few PCI slots. Including the card that means 3 slots for this device alone, but for systems that don't already have a water cooling setup it's a fantastic idea for overclockers. Depending on price this could make a great OC card, especially with the new core revision for the GTO GPUs.
