The coolant channels coming out of the pump+block assembly go straight to a compact rectangular radiator that's under the cooler shroud, and gets ventilated by the three fans. This radiator has surface area comparable to that of a standard 120 mm x 120 mm radiator. Further, the pump+block shares its cooling onto a secondary heatsink assembly which cools the VRM, memory, and the GPU. This secondary heatsink has its own aluminium fin-stack.It's an interesting concept and what makes it even more curious is that you can connect it to your own loop as the card as Watersprout comes with fitting, too!
The company plans to use this new cooling solution on many of its upcoming high-end video cards.
