One of the biggest additions is their anti-leak system. Deepcool have been developing this anti-leak technology for three years now and are pushing it hard on their latest AIO cooling loops, hopefully taking away one of the biggest risk factors of putting, what is essentially, a quantity of conductive liquid into your system. The anti-leak mechanism works by incorporating a rubber 'bung' into the radiator where the elastic properties of the rubber can accommodate for pressure, and therefore volume, changes within the loop.
