Decenas de miles de entusiastas de la refrigeración silenciosa tienen fe ciega en el clásico NF-P12 de Noctua. Su impresionante silencio, excelente rendimiento y calidad impecable, probada a largo plazo, han convertido al P12 en la primera elección para la refrigeración silenciosa de 120 mm.
Diseño de nueve aspas de presión optimizada

Diseño de nueve aspas de presión optimizada

Diseñado específicamente para aplicaciones de alta impedancia como disipadores de CPU, radiadores de refrigeración líquida o cajas con estrechas rejillas del ventilador, el NF-P12 proporciona una presión superior y un mayor rendimiento en cuanto a caudal de aire.
Fentes Vortex-Control

Fentes Vortex-Control

Las Vortex-Control Notches (muescas de control de vórtice), seña de identidad de Noctua, dividen los vórtices de los extremos de los ejes y, por tanto, extienden la emisión sonora del ventilador en un rango de frecuencias más amplio. Esta medida hace que el sonido del NF-P12 PWM sea más agradable para el oído humano.
PWM IC de diseño personalizado con SCD

PWM IC de diseño personalizado con SCD

Al proporcionar control de la velocidad PWM completamente automático, el NF-F12 utiliza el nuevo diseño personalizado NE-FD1 PWM IC que integra la tecnología SCD (Smooth Commutation Drive). Al proporcionar impulsos de torsión más fluidos, SCD suprime los ruidos de conmutación y, por tanto, hace al ventilador más silencioso a velocidades bajas.
Consumo energético ultrarreducido

Consumo energético ultrarreducido

El NF-P12 solo consume 0,6 W, menos del 50 % de lo que consumen otros ventiladores PWM. Esto no solo lo hace más ecológico, sino que también reduce la factura de la electricidad: En comparación con un ventilador típico de 2 W, permite ahorrar aproximadamente la mitad del precio del NF-P12 después de 5 años de uso continuo.
Adaptador para reducción del ruido

Adaptador para reducción del ruido

El NF-P12 PWM está provisto de un adaptador para reducción del ruido (LNA) que reduce la velocidad máxima del ventilador de 1300 a 900 rpm. El LNA se puede utilizar bien para que el ventilador funcione a una velocidad fija de 900 rpm o para limitar la velocidad máxima cuando se utiliza el control PWM automático.
Extensas opciones de cableado

Extensas opciones de cableado

El cable corto principal del ventilador, de 20 cm, minimiza la acumulación de cables en las aplicaciones típicas, mientras que el cable de extensión de 30 cm incluido proporciona un alcance mayor cuando sea necesario. Ambos cables están completamente enmallados y un cable de 4 pines en forma de Y permite conectar un segundo ventilador PWM al mismo conector del ventilador para obtener control automático.
Rodamientos SSO-Bearing

Rodamientos SSO-Bearing

La combinación del eficaz concepto de rodamientos hidrodinámicos con un imán adicional que apoya la autoestabilización del eje del rotor convierte a la tecnología SSO-Bearing de Noctua, de probada eficacia, en sinónimo de una operación sumamente silenciosa y una excepcional estabilidad a largo plazo.

NF-P12 PWM Opinión

All in all, these products are well built, well designed, and are able to achieve specs that by-and-large merit the premium price asked of them. None of the tested fans exhibited loud operation, and the included accessories ensured that the fans can be used in many different systems.
Resultado del análisis: "It is typical for high-end or “luxury” goods to embrace a brand, style, or ethos, and Noctua does precisely that with their distinctive color scheme. The rest comes down to performance, though, and while you’ll pay top dollar to install a Noctua fan in your build, we’re hard-pressed to imagine how anyone will find themselves disappointed."

NF-P12 PWM Opinión

En ce qui concerne le NF-P12 il est inaudible en 5v et devient audible en 12v, par contre le bruit généré n'est pas touché par des bruits parasites, tout ce que l'on peut entendre est un souffle et c'est un très bon point !
Resultado del análisis: "Le NF-P12 montre des performances un peu moins bonnes que le NF-F12 mais le bruit émis est plus doux à l'oreille, il sera donc plus adaptée sur un ventirad dans un PC silencieux. Les performances restent quand même très bonnes et sera un très bon compromis entre silence et performance." (Christian Marchini, Conseil Config)

NF-P12 PWM Opinión

We plugged in the case fan slot of our motherboard and disabled the PWM function to use the fans at their full speed. We also tested the fans at PWM speeds and with L.N.A adapter without PWM. Noise levels with all the fans are similar. In PWM mode, with our test setup, the fans were running at minimum speed nearly the whole time. Only after extensive 3DMark Vantage sessions the fan speed rose above the minimum. Even then the fans were very silent. With L.N.A adapter one could barely hear the fans. When we disabled the PWM and ran the fans at 12V, they were clearly audible. However, increasing noise comes with increasing performance. We saw about 2C decrease in overall temperature of the case when using the 120mm fan as our exhaustfan compared to the situation where the same fan was used with L.N.A adapter or PWM. Yet again Noctua did not disappoint us. The quality is on par with previous incarnations of their fans and performance is also on a very good level.
Resultado del análisis: "If you can live with the pricetag Noctua is a great choice. All three fans were absolutely one of the most silent one’s I’ve encountered, and while there definitely are more powerful fans available – the Noctua fans should be more than enough for cooling your case, processor cooler or even your water coolers radiator. All the fans are PWM controlled so you can control their speeding behaviour from your bios or from your motherboards control utility in your operating system. I can recommend all these fans to whoever who is looking for silent, yet reasonably powerful fan, and does want the PWM feature. Noctua won’t let you down in terms of quality!"

NF-P12 PWM Opinión

Tirare delle conclusioni sulle nuove proposte di Noctua non è decisamente semplice; la casa austriaca questa volta mette decisamente tanta carne al fuoco con un "know how" costruttivo che se paragonato a quello delle aziende concorrenti mette decisamente in imbarazzo per la propria superiorità in campo fluidodinamico e non solo. Partendo da un punto di vista meramente qualitativo, le ventole offerte dalla casa austriaca sono tutte dotate di un eccellente qualità dei materiali e costruttiva; tutte le saldature di interconnessione tra i profili palari e il rotore centrale vengono fatte in maniera pressochè perfetta, con margini di tolleranza ridotti all'osso e con una struttura nel complesso decisamente ben curata in ogni sua minima parte. A sostegno di cio c'è la cura quasi maniacale dedicata allo sleeving dei cavi di controllo e di alimentazione, essa viene effettuata con una calza in multifilamento ad alta copertura siliconata, terminata da generosi tratti di termorestringente nero che ne assicura la presa e la stabilità nel tempo; a ciò viene inoltre affiancata una sleevatura direttamente nel frame della ventola che prevede specifici ponti in plastica per il mantenimento in sede dei cavetti che vanno al motore SSO della casa.
Resultado del análisis: "Il lavoro impressionante effettuato da Noctua si vede infine nel grafico del pescaggio che solitamente pone come fanalino di coda le ventole aventi alte pressione statiche, questo con le ventole in oggetto non succede ma anzi le inserisce in vetta esaltando l'ottimo bilanciamento che gli ingegneri della casa sono riusciti a tirare fuori in maniera pressochè esemplare meritando sicuramente i nostri complimenti per il lavoro svolto."

La NF-P12 PWM è ottima con dissipatori e radiatori, o come ventola per case, la NF-B9 PWM è una ventola destinata all’utilizzo su dissipatori per cpu di dimensioni inferiori o su dissipatori per vga, la NF-R8 PWM è perfetta per raffreddare in maniera concentrata un determinato componente (ram, chipset, vrm). I prezzi, in apparenza elevati, sono giustificati dal bundle ricco e dalla qualità costruttiva.
Resultado del análisis: "Con la nuova famiglia di ventole PWM, Noctua ha dotato arricchito tecnicamente le sue gia ottime ventole. I consumi sono stati ridotti visibilmente e c’è tutta la comodità del PWM. Consigliamo queste ventole a chiunque voglia raffreddare in maniera efficiente il proprio computer, sena rinunciare al silenzio." (Rocco Eduardo Battista, HWMaster.com)

NF-P12 PWM Opinión

Avec un seul ventilateur, les performances en refroidissement, comme vous pouvez le voir sur les graphiques, sont inférieures à celles du ventilateur Scythe, mais avec un écart qui est dans tous les cas inférieur à 3 degrés, que ce soit à 3.8 GHz ou à 5 GHz, au maximum de sa capacité ou en PWM avec un adaptateur LNA. C’est plus que satisfaisant pour un ventilateur qui brasse en théorie deux fois moins d’air (110 CFM pour le Scythe contre 55 pour le P12 PWM), surtout si on tient compte de la différence en terme de nuisances sonores. En Push Pull, le NF-P12 PWM est plus performant que le 120 mm de Scythe, sauf à 100% de la vitesse de rotation (réglage max.) où les températures obtenues sont équivalentes pour ces deux ventilateurs. [...] Le Scythe de 120 mm est vraiment bruyant à 100%, et dégage un son assez aigu. Et la disposition en Push pull le rend encore plus bruyant. Le NF-P12 est quasiment inaudible, on n’entend qu’un très léger souffle.
Resultado del análisis: "Si on ne tient pas compte de la légère différence à 100% de la vitesse de rotation (ce réglage n’étant pas vraiment viable pour le Scythe qui a servi de référence pour ce test), le NF-P12 PWM est aussi performant que le 120 mm de Scythe, avec une différence vraiment flagrante quand il s’agit du silence."

Ebenfalls werden im Video alle Modelle mit einem einfachen Mikrofon, das die Lautstärke aus 10cm Entfernung misst, auf ihr Geräuschlevel getestet. Um eine weitere Orientierung im Sinne der Geräuschkulisse zu geben, haben wir zusätzlich 3 weitere Lüfter (Sharkon Silent Eagle 2000-80mm, 2000rpm @38,5m³/h, Enermax Magma-120mm, 1500rpm @117,49m³/h und ein standart-Gehäuselüfter-120mm, 1000rpm) sowie eine etwas ältere und lautere IDE-Festplatte @7200rpm dem Lautstärketest unterzogen. Schlussfolgernd kann man an dieser Stelle sagen, dass die Lüfter alle sehr gut abgeschnitten haben.
Resultado del análisis: "Oft sind Markenlüfter überteuert und der Preis ist nicht gerechtfertigt. Ob es sich allerdings lohnt, etwas mehr Geld für Noctua-Produkte auszugeben? -Wir sagen: Ja! Die neue Lüfterserie ist aus unserer Sicht eine klare Kaufempfehlung und man hört die Qualität im wahrsten Sinne des Wortes heraus." (Tobi Borho, Whitex-Modd.de)

NF-P12 PWM Opinión

Questo traguardo però non è solo da attribuirsi al disegno particolare delle pale, ma anche al sistema idrodinamico di cuscinetti e alla stabilizzazione magnetica oltre che alla tecnologia SDC! Quest’ultima poi permette alla ventola di consumare molta meno corrente: la potenza assorbita infatti è di appena 0,60 Watt (come dichiarato da Noctua e testato da me durante i test) contro i 1,08 Watt assorbiti dal modello precedente non PWM, la NF-P12. Utilizzando il cavetto riduttore di potenza in dotazione, la velocità della ventola scende a circa 930 rpm mantenendo un ottimo flusso con un rumore già quasi inudibile anche se ancora percepibile. Le vibrazioni sono quasi del tutto assenti. Disponendo di un rheobus o un variatore elettronico della velocità, portando la Noctua NF-P12 PWM a 810 rpm il rumore diviene inudibile garantendo comunque un flusso d’aria sensibile.
Resultado del análisis: "La ventola Noctua NF-P12 PWM è chiaramente un prodotto eccellente che vanta caratteristiche uniche. La garanzia di silenziosità è ciò che contraddistingue i prodotti Noctua dagli altri e questa ventola fa persino un passo in avanti rispetto ai modelli precedenti. Mantenendo basso e ovattato il rumore anche ad alti regimi la rende ottima per qualsiasi utilizzo, dall’HTPC da tenere in salotto ai PC più potenti per il gaming o la computer grafica."

I get a CPU fan error using my Noctua PWM fan, is it faulty?

Noctua PWM fans feature a minimum speed of 300rpm to allow for ultra quiet operation when your CPU is at idle state and doesn’t require higher cooling performance. Some mainboards display error messages such as “CPU fan error” during the booting process when the fan speed is below a certain level. If you get such error messages using your Noctua PWM fan and if such options are available in your BIOS, please either adjust the minimum fan speed monitoring limit to 200rpm or increase the minimum PWM duty cycle. If your BIOS doesn’t offer these options, please disable CPU fan errors. For detailed information on BIOS fan settings, please consult your mainoard’s manual or contact your mainboard manufacturer.

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).

How big is the NH-D15S and how much clearance does it provide for RAM and mainboard heatsinks? Copy

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.
