All the different next-generation All-in-One liquid CPU cooler solutions on display at Computex had one thing in common: They are all designed primarily to avoid an Asetek lawsuit. The Denmark based Asetek holds U.S. Patent No. 8,240,362 involving an integrated self-contained single chamber solution for CPU liquid cooling with a pump, heat exchanger and reservoir, and has vigorously defended their claim in court, winning against Cooler Master in 2012. This limited the variety of AIO CPU Coolers in the market but manufacturers have adapted in their own ways to circumvent the patent claim.
Lian Li took the Swiftech route and separated the pump and reservoir by mounting it close to the radiator. Silverstone moved the pump into the radiator resulting in a much slimmer block, claiming minimal performance hit. Be quiet! Is utilizing a reverse-flow system. Raijintek however showed the most impressive solution with a pump less cooling system.
Raijintek’s solution involves the use of a special formulated liquid that boils when the CPU is heated, turns to gas passing through the radiator (and the heat with it) then condenses down to liquid to repeat the process ad infinitum. Watch the video below to see the demonstration of the cooling solution in action:
Raijintek said that they are just finalizing worldwide patents and their AIO will be ready for release. They currently offer the Triton AIO and have the Atlantis series of DIY water-cooling kits (which appear to be the same OEM as Heatkiller units). The best part about this news however is that Raijintek says the implementation is simple and not costly at all so in keeping with their pricing, these upcoming pump less AIOs will be quite affordable as well.
