Fan Speed: 800 RPM, Black/White, Extra Quiet Motor, Computer, Ultra-Quiet, ARCTIC F14 Silent, 140 mm Case Fan, Almost inaudible

#ad
ARCTIC #ad - Technical data: fan speed: 800 rpm, noise level: 008 sone @ 800 rpm, airflow: 46 cfm/78 m³/h @ 800 RPM, Pin: 3-pin. 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.

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 higher service life. Innovative design: design of fan blades improves air flow and facilitates efficient ventilation, impeller was designed with a focus on minimzing the noise level yet delivering the desired airflow and pressure. Two way installation: Blow warm air out of the case, draw cool air into your case.
