Noctua - Bild

Product discontinued. Successor model: NF-S12B ULN

Sound-optimised 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 optimisation 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. button

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

(Rene Ruf,

02.10.2015 - BUG 10/2015 NH-U9S
Test verdict: "Performanse hladnjaka su, s obzirom na njihove gabarite, izvrsne. Pod time podrazumijevamo da će bez problema hladiti većinu procesora koji su trenutno na tržištu, čak i ako se odlučite na overklokiranje." (Denis Arunović;, BUG BUG 10/2015)
