Today appears to be a very sad day for graphics card enthusiasts as Asetek have patented a liquid cooling system for graphics cards. The patent, which will apply in the USA, has the potential to force custom GPU water-block vendors out of the GPU market from what I can see. The likes of EKWB, Koolance and Aquacool may be forced to move production outside the USA and stop selling to the American market in a similar way Swiftech had to when Asetek raised litigation claims against them for patent violations of the AIO CPU cooler design
