The pump now uses a six-pole motor under full PWM control, adjustable from 3000 to 5500 RPM, so it can be slowed right down when the processor is idle. The two Pure Wings 3 120mm high-speed fans are daisy-chained, leaving a single fan cable to route, and the flexible sleeved tubes are 400mm long. A refill port is built into the radiator for topping up over the cooler’s life.
