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

Test verdict: "If you are building a small form factor system or even have a rackmount system and you are looking for a good air cooler that will not have any size restrictions then the NH-D9L is a great choice." (Bob Buskirk, ThinkComputers.com)

Test verdict: "The Noctua NH-D9L packs alot of cooling in a little package. If you are needing to save the space but do not want to sacrifice performance the dual fan setup competes pretty close to the big behemoth coolers." (Chris McCart, FunkyKit.com)

Test verdict: "Overall, I believe Noctua makes an excellent product. There really isn’t anything I can complain about except for the price, and even then the price is understandable. If you need good air flow, low noise and have a small form factor case that needs some better fans, I could definitely recommend what Noctua has to offer here." (Josh Jackson, PureOverclock.com)

03.03.2015 - FrostyTech.com NH-U9S
Test verdict: "Given these height and footprint size restrictions, the Noctua NH-U9S is a pretty quiet heatsink that offers very good thermal performance in the sub-125mm tall heatsink category, making it an excellent choice for PCs which are severely space limited. The results are enhanced by adding a second fan, as we've shown over the course of this review. Couple that with awesome build quality and a 6 year warranty and it's not hard to recommend this cooler." (Max Page, FrostyTech.com)
