Sunon's Waturbo is a sophisticated CPU cooling device that combines air and liquid cooling in a compact, self-contained product. The manufacturer calls it a liquid circulation system that uses the fan motor to drive a pump for the coolant. The 92 mm fan and the pump are coupled magnetically to transfer the torque, which avoids mechanical resistance. Thanks to the coolant circulation, heat is dissipated efficiently from the processor surface and emitted to the radiator / heat sink elements immediately, where the fan dissipates it into the surrounding air. This 645 g cooler was designed for both AMD and Intel platforms and should provide lowest-noise cooling for all processor models that are within a maximum power envelope of 130 W.
