Le NF-S12A correspond à la troisième génération de ventilateurs silencieux pour boîtiers issue de la gamme S12 de Noctua qui bénéficie de plus de 250 récompenses et recommandations de la part de la Presse internationale. Doté de pales dont la conception a été encore optimisée grâce à l’intégration de protubérances anti-décrochage (Anti-Stall Knobs) dont l’action se conjugue à celle du nouveau cadre AAO (Advanced Acoustic Optimisation), le NF-F12A apporte un gain flux/silence pouvant atteindre 8% comparé à son célèbre prédécesseur. La version PWM bénéficie du circuit propriétaire NE-FD1 IC de Noctua qui permet un contrôle totalement automatisé de la vitesse via les connecteurs de ventilateurs 4-broches. L’adaptateur faible bruit (LNA) fourni permet par ailleurs, en mode PWM, de plafonner la vitesse à 900rpm (au lieu de 1200rpm). Sa discrétion étonnante, la présence des roulements de référence SSO2 et le niveau de qualité extrême garanti par Noctua font du NF-S12A le ventilateur idéal pour le refroidissement silencieux des boîtiers.

Le succès du design S12

Le NF-S12A correspond à la troisième génération de ventilateurs à pales droites issue de la célèbre gamme S12 de Noctua, largement récompensée et plébiscitée par la Presse spécialisée et par les nombreux utilisateurs dans le monde. Les dernières optimisations, qui offrent une efficacité accrue en termes de silence et de flux d'air, font du ventilateur NF-S12A le compagnon idéal des boîtiers silencieux.
Protubérances anti-décrochage (Anti-stall knobs)

Protubérances anti-décrochage (Anti-stall knobs)

Les protubérances anti-décrochage permettent de réduire le phénomène de séparation des flux qui peut s'opérer à résistance moyenne ou haute. Ce dispositif permet ainsi d'améliorer la plage de fonctionnement sans décrochage. Par conséquent, le NF-S12A devient encore plus polyvalent que son célèbre prédécesseur et offre des performances encore meilleures pour une utilisation sur ventirad ou sur radiateur pour watercooling.
Silentblocs anti-vibration intégrés

Les silentblocs anti-vibration intégrés, fabriqués à base de silicone extra souple, amoindrissent la transmission des micro-vibrations tout en assurant une parfaite compatibilité avec les systèmes de fixation et les agrafes pour ventilateurs de ventirads.
Système électronique exclusif PWM avec SCD

Système électronique exclusif PWM avec SCD

Compatible avec les systèmes de contrôle de vitesse automatisé PWM, NF-S12A PWM est pourvu du tout dernier circuit NE-FD1 PWM IC qui intègre la technologie SCD (Smooth Commutation Drive). En générant des impulsions de couple moins brutales, le SCD élimine les nuisances sonores liées aux commutations du PWM pour une ventilation moins bruyante à vitesse réduite.
Adaptateur Faible Bruit

Adaptateur Faible Bruit

Le NF-S12A PWM est livré avec un adaptateur faible bruit (appelé L.N.A. pour « Low Noise Adaptor ») qui fait chuter la vitesse maximale de 1200 à 900rpm. Le L.N.A. convient aussi bien pour un fonctionnement à vitesse fixe (900rpm) que pour une utilisation en mode PWM bridé (limitation de la vitesse maximale).
Options étendues de câblage

NF-S12A PWM test

All of Noctua’s products are of a very high build quality and they have the science to support their design choice.
Verdict du test: "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 PWM test

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.
Verdict du test: "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 PWM test

I materiali sono interamente plastici di ottima fattura, opache in ogni loro parte e con uno spessore delle plastiche davvero notevole che le rende solide e resistenti senza appesantirle molto, ad ogni angolo troviamo le coperture di gomma che attenuano le vibrazioni anche non in presenza dei gommini appositi, una chicca davvero utile se sono collegate a radiatori o similari. Le Noctua S12A possiedono delle pale con un profilo più aggressivo e angolatura accentuata assieme a delle protuberanze alle estremità di esse che fendono in modo diverso l’aria e migliorano il flusso ma soprattutto evitano lo stallo dell’aria e quindi un effetto controproducente a causa della turbolenza, inoltre la superficie interna particolare riduce ulteriormente la rumorosità dell’aria (AAO Technology).
Verdict du test: "Le NF-S12A si sono confermate tra le ventole più silenziose ed efficienti del mercato, che viene proposta in diverse salse in base alle proprie esigenze: PWM per utilizzo con CPU, FLX per chi vuole la massima flessibilità per la velocità di rotazione, ed ULN per il minimo rumore ed un flusso d’aria leggero ma costante."

NF-S12A PWM test

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.

NF-S12A PWM test

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.
Verdict du test: "Le ventole Noctua NF-S12A risultano molto prestanti e silenziose." (Enrico Luperini, GameTechModding.com)

NF-S12A PWM test

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.
Verdict du test: "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 PWM test

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.
Verdict du test: "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."

Dopo aver fatto questi test ci riteniamo abbastanza soddisfatti soprattutto per quanto riguarda il rumore, che a distanza di 60cm dopo aver installato 3 ventole rimane comunque inudibile. Per le temperature non ci aspettavamo grossi miracoli ma qualche grado in meno nello stress test ci avrebbe fatto molto piacere. A livello bundle riteniamo che sia di prima qualità, troviamo infatti tutto quello che può servire, dagli adattatori alle prolunghe fino ad arrivare alle viti in gomma per un sistema ancora più silenzioso. Insomma queste scelte sono eccellenti in ogni loro aspetto, seppur la colorazione non sia apprezzata da molti, sono disponibili tutte e tre ad un prezzo di 19,90€ su Amazon. Quello che vi consigliamo è che qualora sceglieste di acquistarle, di fare bene i conti dei CFM in entrata e in uscita che avrete una volta installate.
Verdict du test: "Noctua ha dimostrato ancora una volta di essere leader nel settore grazie alla qualità delle sue componenti che è possibile notare anche solo dall'accuratezza con cui è stata realizzata la scatola. Prestazioni eccellenti e rumore impercettibile sono le parole chiave di questo prodotto." (Davide Torno, QWERTYmag.it)

NF-S12A PWM test

Unter Kennern ist Noctua bekannt. Nicht nur wegen der markanten Gestaltung der Lüfter, sondern auch wegen der Technik die hinter den Lüftern steckt. Diese Generation der Noctua-Lüfter verbessert das SSO-Lagersystem. Mit SSO2 befindet sich der Magnet noch näher an der Lüfterachse, um mehr Stabilität zu gewährleisten. Zur verbesserten Stabilität und geringer Vibration tragen außerdem integrierte Vibrationspuffer und abgestufte Einlassbereiche bei. Noch wichtiger ist aber die Mikrosturktur im Innenbereich. So gewährleistet euch Noctua mit seinen Lüftern eine herausragende Laufruhe. Auch das Antriebsystem hat Noctua verbessert. So werden zum Beispiel Switching-Noises einfach eliminiert.
Verdict du test: "Für alle, die ein bisschen auf Verarbeitung, Leistung und vorallem die Lautstärke ihrer Lüfter achten, bringt Noctua mit diesen drei Lüftern ein perfektes Trio. Je nach Bedarf, ob schnell, langsam oder extrem leise drehend, für jeden ist etwas dabei." (Lukas Heinrichs, Basic-Tutorials.de)

NF-S12A PWM test

These fans in their various set ups give very good air flow performance when used as an exhaust fan, but they give even better performance when used to quieten a chassis down. Despite their low noise credentials we found a flatter performance profile when it comes to cooling. Giving the chassis one exhaust fan and no intake fan gave each version the job of intake and exhaust, not an easy task.
Verdict du test: "Using the three variants of the same fan it was clear that a system builder could manage airflow and noise with a high degree of accuracy. The level of design and thought in these fans is amazing, you will know it when you feel and open the box." (Jim McGhee, Hardwareslave.com)

My Noctua PWM fan starts to spin when the PC boots but then stops, what is wrong?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). In this case, it may occur that the mainboard reduces the voltage so much that the fan stops. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.



To resolve the issue, you can:

  1. Choose a higher fan speed profile in the BIOS (e.g. „normal“ instead of „silent“, etc.) or deactivate automatic fan speed control and use a Low-Noise Adaptor instead.

  2. Use the mainboard‘s fan speed control software or 3rd party tools like Speedfan to regulate the fan speed. Unlike BIOS based fan speed control, the supplied software usually checks whether the fan has stopped and increases voltage accordingly or at least offer more options to set up the fan properly.

  3. If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

My Noctua PWM fan runs at a much higher minimum speed than advertised, what is wrong?

The specified minimum speed refers to the speed at 20% PWM duty cycle. There can be several reasons why the fan doesn‘t go as low as indicated:

  1. Many mainboards do not go below 40%, 50% or even 60% PWM duty cycle on case fan headers. Please refer to your mainboard manual to verify whether the fan header actually goes down to 20% duty cycle. If that's not the case, in some cases you can use the fan speed control software supplied with your mainboard to overcome these limitations and reduce the fan speed even further. However, 3rd party tools like SpeedFan offer greater flexibility and better options to work around the limitations imposed by the mainboard vendors.

  2. Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

    4 pin fan header types

    Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.


    If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.

I'm experiencing fan speed issues with my motherboard from Supermicro, what can I do?

The BIOS of many motherboard models from Supermicro expects a certain minimum fan speed (usually 700rpm), which is higher than the minimum fan speed that can be achieved with Noctua's PWM fan models. The BIOS may interpret the low minimum RPM of Noctua fans as a fan error and thus try to run the fan at 100% for a short period before going back to automatic control.. This can result in oscillating fan speeds and fan speed warnings in the BIOS or the fan management console.

Unfortunately there is usually no option to set a lower minimum value that would suit the low minimum speed of Noctua PWM fans.The issue can thus only be resolved by either disabling automatic fan speed control in BIOS, which will cause the fans to run at a constant speed, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply).

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!

D15S

Can I run 4-pin PWM fans on 3-pin fan headers?

PWM fans come with a 4-pin connectors for fully automatic speed control via your mainboard’s 4-pin PWM fan headers. Please note that 4-pin fans can also be connected to your mainboard’s 3-pin fan headers though. When connected to 3-pin fan headers, the fan will run at full speed (unless the mainboard supports voltage based speed control).

The supplied y-cable is missing a wire at one of the two connectors, is it faulty?

No. As mainboards can process only one rpm-signal per fan header, it would cause problems if the cable transmitted rpm-signals of both fans. For this reason, one of the two connectors does not have an rpm wire and only the fan on the other connector will transmit an rpm signal. Automatic speed control of both fans will work independent from the second fan’s rpm signal.

How can I check if my 4-pin fan header supports PWM?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM.
