Noctua NF-S12A ULN 120MM Cooling Fan 800RPM Case Low-NoiseAnti-vibration 3-Pin
**NEW ORIGINAL RETAIL BOX BRAND**
The NF-S12A marks the third generation of Noctua’s signatureS12 series quiet case fans, which have received more than 250 awards andrecommendations from the international press. Featuring a further refined bladedesign with Anti-Stall Knobs that works in tandem with the new AAO (AdvancedAcoustic Optimisation) frame, the NF-S12A improves the airflow/noise efficiencyof its renowned predecessor by up to 8%. The ULN version provides super-slow800/600rpm speed settings for ultra-low-noise applications and highly noisesensitive users who demand near-silent operation. Its superb runningsmoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elitechoice for quiet case cooling.
Details
Award-winning S12 design
The NF-S12A features the third evolution of Noctua's classicStraight Blade Design that has earned its S12 series countless recommendationsfrom hardware journalists and enthusiasts around the world. Further optimisedfor even better airflow/noise efficiency, it makes the NF-S12A an ideal quietcase fan.
Anti-Stall Knobs
The NF-S12A's Anti-Stall Knobs reduce flow separationphenomena in medium to high impedance situations and thereby increase the fan'sstall margin. This means that the NF-S12A is even more versatile than itsrenowned predecessor and can achieve better performance on heatsinks andradiators.
AAO Frame
Noctua's AAO (Advanced Acoustic Optimisation) frames featureintegrated anti-vibration pads as well as Noctua's proprietary Stepped InletDesign and Inner Surface Microstructures, both of which further refine thefan's performance/noise efficiency.
Stepped Inlet Design
Noctua's Stepped Inlet Design adds turbulence to the influxin order to facilitate the transition from laminar flow to turbulent flow,which reduces tonal intake noise, improves flow attachment and increasessuction capacity, especially in space-restricted environments.
Inner Surface Microstructures
With the tips of the fan blades ploughing through theboundary layer created by the Inner Surface Microstructures, flow separationfrom the suction side of the blades is significantly suppressed, which resultsin reduced blade passing noise and improved airflow and pressure efficiency.
Integrated anti-vibration pads
Integrated anti-vibration pads made from extra-soft siliconeminimise the transmission of minute vibrations while maintaining fullcompatibility with all standard screws and other mounting systems.
Smooth Commutation Drive 2
The latest version of Noctua's advanced Smooth CommutationDrive system ensures superb running smoothness by eliminating torque variationsand switching noises. This makes the NF-S12A remarkably quiet even at veryclose distances.

2 speed settings for maximum quietness
Providing 800 and 600 rpm speed settings via the suppliedadapter, the ULN (Ultra-Low-Noise) version is tailor made for serious silententhusiasts who demand super-slow running speeds and utmost quietness ofoperation.
Extensive cabling options
The fan's short 20cm primary cable minimises cable clutterin typical applications while the supplied 30cm extension provides extendedreach when necessary. Both cables are fully sleeved.
SSO2 Bearing
The NF-S12A features the further optimised second generationof Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet isplaced closer to the axis to provide even better stabilisation, precision anddurability.
