F9 Silent 3-Pin fan with standard case
- At low fan speed, the motor noise is key. A motor developed in Germany with a new alloy/lubicant combination reduced friction and noise.
- The Fluid Dynamic Bearing comes with an oil capsule that avoids lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but comes with a significantly higher service life.
- The innovative design of the fan blades improves the airflow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimzing the noise level yet delivering the desired airflow and pressure.
