The Enermax Cluster Advance is one of the few white fans on the market with four switchable white LEDs that complete its elegant design. The speed range of the fan can be selected by the Adjustable peak speed (APS) function in three stages: Ultra Silent Mode / Silent mode / Performance mode. Within the selected operating mode, the fan speed is automatically controlled by pulse width modulation (PWM). The Enermax Cluster Advance is therefore a versatile fan: it’s perfect for silent PC but also for powerful workstations. Enermax used the well-known Twister Bearing technology, which ensures a smooth and long lasting operation up to 160,000 hours. The specially shaped Batwing fan blades increase the air flow by up to 20% and can be removed for cleaning.
