Arctic F9 9.2cm Case Fans x 5, Black, 9 Blades, Fluid Dynamic, Value Pack (5 Fans)

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 air flow 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.
