Magnetic-levitation technology: Prevent slanting, friction and noise. Minimized blade hub: Enlarge airflow channel. PWM driver IC: Control the fan speed easily. Dynamic balance calibration treatment: Enhance the performance Anti-vibration pads: Decrease the noise. Direct-flow frame: Help direct airflow, improving both throughput and static pressure performance. Grooved fan blades: Lower the noise, improve sound quality and performance.
