Zalman ZM-F1 FDB Computer case Fan

ZM-F1 FDB, Fluid Dynamic Bearing, 18 - 23dBA ± 10%, 1400 - 2000rpm ± 10% 150,000 Hours Guaranteed Product Lifespan
FDB (Fluid Dynamic Bearing) 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 lifespan (150,000hrs) with minimum noise.

Anti-Vibration Silicone Pins
Anti-Vibration Silicone Pins absorb vibrations caused by friction with the case.

Adjustable Fan Speed
Included resistor cable (RC56) adjusts input voltage, allowing user to control fan speed and noise.
