120mm Case Fan, 1200 RPM, 47.7 CFM, 17 dBA, Retail

Overview:

Sound-optimized blade geometry and profile: The NF-S12 is the first fan employing a novel rotor which was developed by the Austrian Institute for Heat-Transmission and Fan Technology (Österreichisches Institut für Wärmeübertragung und Ventilatorentechnik, ÖIWV). Thanks to the special optimization of the blade geometry towards ultra low noise application, the NF-S12 is up to 10% more quiet than current high-end fans at the same flow rate.

Self-stabilizing oil-pressure bearing (SSO bearing): The NF-S12 series are equipped with a magnetically centered, self lubricating oil-pressure bearing that provides a new level of quietness and long-term stability.
