Extremely silent, extremely powerful! The new Xilence XQ DualWing fans prove that silent does not mean inefficient. Due to the DualWing technology, an increased airflow with a low fan speed is achieved. The smaller, overhead rotor blades ensure for a smooth airflow and increase the fan performance. The innovative XQ high performance fan comes with a rubber decoupler which lies on the entire surface of the fan to prevent vibrations to the case.
