The Noctua fans are the first fans to employ a novel rotor design developed by the Austrian Institute for Heat Transmission and Fan Technology, which is up to 10% more efficient than ordinary high-end fans thanks to a special optimization of the blade geometry towards ultra low noise application. Outfitted with self-stabilizing oil-pressured SSO-Bearings, the Noctua fans provide a whole new level of quietness and long-term stability.
Sound-optimized blade geometry and profile: The NF-R8 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-R8 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-R8 series are equipped with a magnetically centered, self lubricating oil-pressure bearing that provides a new level of quietness and long-term stability.
Current silent fans frequently employ conventional blade geometries, which were developed for higher speed ranges and significantly lose efficiency at lower rotation speeds. The Noctua Straight-Blade-Design of the NF-R8 series was developed by the Austrian Institute for Heat-Transmission and Fan Technology (Österreichisches Institut für Wärmeübertragung und Ventilatorentechnik, ÖIWV) and specifically tailored to 120mm fans with extremely low rotation speeds. The result is a performance improvement of up to 10% and more compared to conventional blade geometries.
