Perfect fan regulation through PWM The PWM function signals precisely via the motherboard the speed at which the fan should operate. This guarantees maximum cooling performance at minimal noise levels. PWM Sharing Technology (PST) reduces noise levels The PST function ensures that all case fans operate on a single signal. This allows for uniform settings across all case fans. Innovative design for quiet and efficient ventilation The innovative design of the fan blades improves airflow, positively influencing ventilation. The fan wheel has been designed with a focus on minimal noise levels while providing enhanced airflow and pressure.
