Award-winning S12 design

Award-winning S12 design

The NF-S12A features the third evolution of Noctua's classic Straight Blade Design that has earned its S12 series countless recommendations from hardware journalists and enthusiasts around the world. Further optimised for even better airflow/noise efficiency, it makes the NF-S12A an ideal quiet case fan.
Anti-Stall Knobs

Anti-Stall Knobs

The NF-S12A's Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan's stall margin. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance on heatsinks and radiators.
AAO Frame

AAO Frame

Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan's performance/noise efficiency.
Stepped Inlet Design

Stepped Inlet Design

Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.
Inner Surface Microstructures

Inner Surface Microstructures

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
Integrated Anti-Vibration Pads

Integrated Anti-Vibration Pads

Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
Smooth Commutation Drive 2

Smooth Commutation Drive 2

The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-S12A remarkably quiet even at very close distances.
2 speed settings for maximum quietness

2 speed settings for maximum quietness

Providing 800 and 600 rpm speed settings via the supplied adapter, the ULN (Ultra-Low-Noise) version is tailor made for serious silent enthusiasts who demand super-slow running speeds and utmost quietness of operation.
Extensive cabling options

Extensive cabling options

The fan's short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved.
SSO2 Bearing

SSO2 Bearing

The NF-S12A features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.
Metal bearing shell

Metal bearing shell

In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-S12A sports a CNC milled bearing shell made entirely from brass.
6-year manufacturer’s warranty

6-year manufacturer’s warranty

NF-S12A ULN Review

Estos ventiladores tiene una calidad desde que tienes el producto en tus manos hasta que lo montas, impresionante. La capacidad de refrigeración de estos ventiladores resulta muy importante en mi caso, vivo en una zona muy cálida de España y llegamos en verano a temperaturas de hasta 38 grados en la sombra. Todos los años mi pc alcanza altas temperaturas por culpa del verano y unos ventiladores con estas capacidades mi PC lo agradecerá.
Test verdict: "Realmente lo que más me ha sorprendido son los niveles de ruido que genera, son prácticamente inapreciables incluso en el modelo ” que más ruido genera”." (Carlos Carraveo, PcGaming.games)

NF-S12A ULN Review

A pieno regime risultano essere quasi inudibili, risultando più silenziose delle standard Cooler Master, migliorando ulteriormente la quantità di aria immessa, abbassando le temperature. Le ULN invece, sono assolutamente silenziosissime ed inudibili anche a case aperto.
Test verdict: "Le ventole si sono dimostrate eccellenti in tutto, c’è poco da dire. Packaging perfetto, prestazioni molto buone per la silenziosità offerta e ben sei anni di garanzia." (Tommaso Biallo, TechHardware.it)

NF-S12A ULN Review

Nie ma co się sprzeczać odnośnie do tych elementów. Jednakże premium oznacza również wysoką cenę. Pomimo upływu lat, NF-S12A nadal kosztuje niemało – około 81-85zł w zależności od wersji. Rekompensację takiej ceny możemy upatrzyć w, chociażby 6-letniej gwarancji.
Test verdict: "Wentylatory Noctua z serii NF-S12A to prawdziwy sprzęt premium, nie tylko z nazwy, ale również jakości wykonania, działania, długoletniej gwarancji czy obiecanej żywotności." (Filip Ciemiński, GamesGuru.org)

NF-S12A ULN Review

Вентиляторы форм-фактора 120 мм являются одними из самых востребованных пропеллеров в современных корпусах и кулерах, даже несмотря на уменьшающееся с каждым годом тепловыделение комплектующих, особенно процессоров и видеокарт. Технологичные устройства от Noctua предлагают пользователю фактически бесшумную работу, высокую эффективность и разнообразие выбора; в ассортименте бренда представлены вертушки на любой цвет и кошелек.
Test verdict: "Универсальные вентиляторы Noctua NF-S12A ULN и Noctua NF-S12A FLX фактически ничем друг от друга не отличаются (речь об эффективности), и в данном случае обратить внимание следует только на отпускную стоимость (приобрести более доступный вариант при прочих равных). Обе модели целесообразнее всего использовать для процессорного кулера." (Евгений Никифоров, ITNdaily.ru)

NF-S12A ULN Review

All of Noctua’s products are of a very high build quality and they have the science to support their design choice.
Test verdict: "This fan is exactly what I was looking for as a case fan. It is professionally designed to be very efficient and very quiet. This fan is ideal if you are looking for a 120mm case fan which runs super quiet and super efficient. I am very happy with this product (as with all my Noctua case fans) and look forward to adding more of their products to my system." (Ryan Tech Reviews)

NF-S12A ULN Review

Each of the fans was easy to install, and fits quite comfortably in the case, with no gaps between case and fan. With three fans installed in my test system and running a recently released game at maximum settings the fans maintained a slightly loud whisper, even under full load, but that’s partly down to the R9 390X I have installed, which can be noisy at full capacity.
Test verdict: "When you’re sat at your computer surfing the internet or working the fans barely register as being on. As I outlined at the start of this post, if you’re building a gaming PC, make sure to invest in two or three Noctua 120mm fans." (Chris Sealey, Building a Gaming PC)

NF-S12A ULN Review

Noctua NF-S12A FLX: a 1200rpm è sorprendente l’assenza di alcuna vibrazione, merito tutto dell’ottima qualità costruttiva che permette un bilanciamento eccellente oltre che ai componenti studiati appositamente per tale scopo, ad esempio il cuscinetto idrodinamico ad olio denominato SSO2 Bearing. Il flusso d’aria è davvero elevato e a tale velocità è impensabile sperare che non produca rumore, anche se contenuto, presenta ancora frequenze alte (che sono le più udibili). Utilizzando il riduttore di potenza LNA NA-RC 10 la velocità massima della ventola scende a 960 rpm dove ancora si può percepire del rumore anche se molto poco e soprattutto a bassa frequenza. Con il riduttore ULNA NA-RC 12 la velocità massima scende ulteriormente a 700 rpm dove non si percepisce più alcun rumore nonostante sia ancora presente un flusso discreto d’aria. Noctua NF-S12A PWM: come per la versione FLX, la Noctua NF-S12A PWM raggiunge una velocità massima di 1200 rpm e con il riduttore di potenza LNA NA-RC 7 raggiunge una velocità massima di 960 rpm. Anche qui dunque valgono le stesse considerazioni appena scritte per il modello FLX. Per arrivare a non udire più alcun rumore occorre abbassare la velocità a 800 rpm. Noctua NF-S12A ULN: questa ventola si differenzia dalle altre due per il fatto che già senza alcun riduttore di potenza la velocità massima è di 810 rpm dove non produce alcun rumore ne vibrazione ne turbolenza. La Noctua ha ponderato molto bene il settaggio di questa ventola limitandola a una velocità in cui il flusso d’aria è soddisfacente e soddisfacente soprattutto per l’orecchio! Se poi aggiungiamo anche il riduttore LNA NA-RC 12 la velocità massima scende a 610 rpm, ma se già a 810 rpm non produceva rumore, non vedo la necessità di ridurre ancora di più la velocità.
Test verdict: "Le ventole Noctua NF-S12A risultano molto prestanti e silenziose." (Enrico Luperini, GameTechModding.com)

NF-S12A ULN Review

En lo personal, me han gustado bastante y son unos productos que recomendaría sí o sí, a no ser que tengas el bolsillo un poco ajustado. Pero pensad en esto: la calidad tiene un precio, y en este caso se nota. Y son unos productos que nos aseguran muy buen rendimiento, grandes prestaciones y muy bunea calidad en los acabados. También quería hacer mención a que estaría bien que tuvieran una mejor cantidad de colores, pero esto algo sin importancia ya que muchos de ellos (por no decir todos) quedarán dentro de la torre y no se serán visibles. Eso sí, en cajas blancas y/o metalizadas, la combinación de colores le da un toque de elegancia y se nota que no estás ante un producto cualquiera. En mi caso, podéis comprobar que el color crema y marrón queda muy bien. Como puntuación final, a los 3 les pongo un 9,5/10.
Test verdict: "Noctua viene demostrando que sus productos están hechos con mucho mimo y cariño y tienen una calidad muy alta." (Pol Ribas, esPCializados.es)

NF-S12A ULN Review

As you can see from the results, the Noctua fans truly raise the dilemma between good performances versus noise. Spotting the differences between 1200 and 600 RPM can be easily done without using any special equipment, yet although the FLX was quite loud, in comparison to other fans I’ve had before it’s less noticeable. This might be due to the added silicon anti-vibration pads that are easily placed. Noctua states that the S12A fans can last for more than 150,000 hours, and provides a six years warranty, three times more than what both Corsair and Cooler Master provide.
Test verdict: "The build quality is top notch and everything from the box to the performance shows that Noctua puts all their efforts in this product." (David Melloul, MadeForGaming.com)

NF-S12A ULN Review

Già a bassissimi regimi di rotazione le ventole della serie Noctua NF-S12A si difendono bene dai concorrenti, in particolare la NF-S12A PWM tiene testa alla soluzione Enermax ed affianca le Blademaster sia in idle che in full load. In poche situazioni quest’ ultima è stato in grado di offrire risultati superiori rispetto alle ventole Noctua.
Test verdict: "Dobbiamo essere sinceri, con Noctua abbiamo fatto davvero fatica a distinguere i diversi livelli di rumorosità già a 900rpm; pur disattivando qualsiasi sistema di dissipazione attiva all’ interno del case inclusa la ventola della PSU arrivati ad un certo punto il componente più rumoroso era la pompa integrata della nostra soluzione all-in-one."

Can I use Low-Noise Adaptors with y-cables / multiple fans?

Yes, Low-Noise Adaptors (L.N.A.s) can be used with y-cables, but please make sure to use one L.N.A. per fan and to place the L.N.A.s between the y-cable and the fans as shown below. Never use one L.N.A. for two (or more fans) by placing it between the mainboard and the y-cable!
