ARCTIC F9 Silent Case Fan - 90mm case fan with low speed

Podrobný popis

F9 Silent Extra Quiet 92 mm Case Fan GREATER EFFICIENCY - LESS NOISE AT HIGHER AIRFLOW At low fan speed, the motor noise is key. A motor developed in Germany with a new alloy/lubricant combination reduced friction and noise. Our impeller is not just quiet but moves at a given fan speed more air than any other product. LONG SERVICE LIFE 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. INNOVATIVE DESIGN ENABLES QUIET AND EFFICIENT VENTILATION 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 DIFFERENT INSTALLATION - Exhaust hot air out of the case - Intake cool air into the case - 3-pin connector for mainboard and power supply that also works with 4-pin headers.
