Zalman ZM-FDB (SF) Ultra Quiet Fan Series

Fluid Dynamic Bearing (FDB) structure generates high pressure oil layer on micro Channel's intersecting point, which prevents friction between the fan's shaft and bearing, thus resulting in maximum fan life span (150,000 hrs) with minimum noise. Shark fin blade design is optimized for maximum airflow, Shark Fin blade greatly reduces the turbulence caused by the fan rotation decreasing the noise and vibration. Minimized noise and vibration is achieved through low rpm. Silicone fan mounts absorb the vibration between the fan and the case allowing a for a quiet work environment.
