Conception à neuf pales pour une pression renforcée

Conception à neuf pales pour une pression renforcée

Spécialement étudié pour les environnements exigeant une pression élevée (ventirads pour CPU, radiateurs pour refroidissement à eau ou boitiers avec grilles d'aération étroites), les neuf pales du NF-P12 délivrent une pression hors norme et un flux imposant.
Vortex-Control Notches (Fentes Vortex-Control)

Vortex-Control Notches (Fentes Vortex-Control)

Les fentes Vortex-Control, qui demeurent une exclusivité Noctua, assurent une dispersion des vortex se développant en bout de pale et répartissent ainsi les émissions sonores sur une plage de fréquences plus large. Ce dispositif permet de générer un son plus plaisant à l'oreille humaine.
Système exclusif PWM IC avec SCD

Système exclusif PWM IC avec SCD

Compatible avec les systèmes de contrôle de vitesse automatisé PWM, le ventilateur 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.
PWM à 0%: arrêt

PWM à 0%: arrêt

Lorsque le ventilateur est réglé sur un rapport de cycle PWM de 0%, que ce soit via la carte mère ou un contrôleur de ventilation PWM, il s’arrête. Ceci permet de créer des configurations avec un refroidissement semi passif qui permet l’arrêt automatique des ventilateurs – pour assurer ainsi un fonctionnement totalement silencieux – en fonction des sollicitations et des niveaux de température.
Smooth Commutation Drive 2

Smooth Commutation Drive 2

La dernière version du système Smooth Commutation Drive de Noctua garantit un fonctionnement tout en douceur grâce à l'élimination des variations de couple et des bruits de commutations. Le ventilateur devient ainsi très discret, même à proximité.
Roulement SSO-Bearing

NF-P12 redux-1300 PWM test

Appearance wise, this fan should fit in with more builds than your typical Noctua, but without that same recognisable colour. Build quality is solid, as you’d expect, with the SSO bearing and magnetic stabilisation reducing noise as well as Vortex-Control Notches spreading out the unavoidable wind noise over more frequency ranges, producing a cleaner and more pleasurable sound. Cutting back the NF-P12 to the core, providing only the fan and a basic mounting system, has provided us with the essential performance without the associated cost that comes with it. Noctua have cut back all non-essential parts to reduce cost, without sacrificing on quality or performance. The NF-P12 Redux carries the torch for the ageing NF-P12.
Verdict du test: "The Noctua NF-P12 Redux competes against a lot of budget-priced fans from several different brands, however, in our experience and testing, the NF-P12 Redux performs far better than most fans, and comes with that all-important 6 year warranty." (Matthew Hodgson, Vortez.net)

NF-P12 redux-1300 PWM test

On stock clocks, under stress test, the NF-P12 1700 PWM was doing 26.67°C delta temps. Both variants of NF-P12 1300 were neck-to-neck with 29°C delta temps. The NF-P12 900 was doing 33.67°C which is on a warmer side particularly on the stock clocks but given its 900 RPM maximum speed and the aim behind it, this level of silent performance is actually good. This is a good performance overall and particularly given the low noise level on these fans, Noctua is once again delivering in the Noise-to-Performance ratio category.
Verdict du test: "The low price tag on these fans makes it ideal for the budget users to have a premium cooling solution from the Noctua without much burden on their wallets. These fans come recommended by us." (Nauman Siddique, EnosTech.com)

Les performances de refroidissement sont à la hauteur de ce que l’on espérait notamment pour la version Redux 1700 qui assure son taf sur toute sa plage de vitesse de rotation. La version 1300 a pour lui son faible niveau sonore et ce même à pleine vitesse où sans être silencieux il reste nettement plus discret que son homologue Redux 1700. De plus avec ce niveau sonore contenu, il se débrouille bien face à notre i7 7700k et nous n’aurons ainsi pas besoin de trop réduire sa vitesse pour ne plus l’entendre. Le ventilateur Redux NF-P12 900 a élu domicile dans le monde du silence !!! Son but n’est pas franchement de s’attaquer à notre processeur mais plutôt à un CPU nettement plus calme en terme d’émission de chaleur comme ceux que l’on peut avoir dans les config bureautique/multimédia. Ainsi il fait son taf dans un silence royale.
Verdict du test: "Comme nous l’avons suggéré en introduction, si décidément vous avez du mal avec les couleurs natives des ventilateurs Noctua, la gamme Redux NF-P12 offre une excellente alternative tant sur le plan des couleurs que de ses performances." (Bertrand Curras, modding.fr)

NF-A12x25 ventilatori donose neke nove tehnologije i materijale, a uz odlične radne karakteristike i zadovoljavajuće nisku radnu buku. Ovo je svakako najtiši ventilator na 2.000 okretaja koji smo čuli, a uz vrlo respektabilne brojke propusnosti i statičkog pritiska. Kao i uvijek, potrudili su se izbaciti nekoliko modela kako bi svatko pronašao opciju za sebe, a sve dolaze po istoj cijeni. Cijena kod Noctue nikada nije bila niska, a to je pogotovo tako kod premium proizvoda, pa A12x25 ventilatori koštaju preporučenih 29.99 €. Ako ih poželite ugraditi na 140-milimetarska mjesta, SFMA1 adapter s dva okvira će vas koštati 11.90 €. Za one koji ne žele izdvojiti za nove ventilatore, razveselit će činjenica kako se dobri stari P12 modeli u Redux seriji prodaju po prihvatljivih 13.90 € bez obzira na izvedbu.

Tym razem mieliśmy okazję przyjrzeć się wentylatorom, wśród których są modele stawiające na ciszę, a także takie, które dają dobrą wydajność. Austriacy na każde ze swoich urządzeń udzielają aż sześciu lat gwarancji. Seria NF-A12x25 prezentuje się perfekcyjnie, pracuje świetnie i niestety jest dosyć droga. Za każdy z wentylatorów przyjdzie nam zapłacić ok. 129 złotych. Do wyboru mamy wersję ULN, FLX i PWM. To oczywiście sporo i za pewne niewielu z Was będzie mogło pozwolić sobie na taki wydatek. Ci co jednak już zdecydują się na ten krok na pewno będą bardzo zadowoleni. W zestawie jest sporo dodatków, dzięki którym dostosujemy parametry pracy wentylatorów do naszych potrzeb. Osoby, które nie potrzebują dodatkowego wyposażenia powinny sprawdzić serię Redux, która jest dwukrotnie tańsza, a jakość wykonania śmigieł wcale nie jest gorsza. Po prostu tutaj mamy mniej akcesoriów w komplecie. Uważamy, że obie rodziny są warte polecenia, a dzięki szerokiej ofercie każdy z użytkowników może wybrać odpowiedni produkt, już spełni jego wymagania.

Can I disassemble my fan for cleaning (or other purposes, e.g. painting)?

In order to ensure flawless operation over many years of usage, all Noctua fans come with a premium grade SSO bearing, which is fully sealed to prevent the entering of fine dust particles. Please note that the fan is not designed to be taken apart by the user. Removing the impeller from the frame will break the sealing of the bearing and results in a loss of warranty.

It is thus recommended to clean your fans using a duster, slightly moist tissue or canned air. Please be careful not to use too much force in order to prevent any damage to the fan. Please don’t use a vacuum cleaner as this may apply excessive force to the fan.

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).

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.

    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.


    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 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.

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.

Can Noctua fans be used to replace noisy stock fans in switches, routers or other network devices?

Noctua fans such as the 40, 60, 80 or 92mm NF-A series models are ideal for replacing noisy stock fans in switches, routers and other network devices in order to make them quieter and thousands of users have managed to significantly reduce the noise levels of their units this way. However, while it is easy and straightforward to replace the fans in some cases, it can be very difficult in others, so Noctua strongly recommends that users carefully research if it is possible to easily replace the fan(s) of their network device before purchasing a Noctua fan for this purpose. Some of the common issues that can occur when replacing pre-installed fans are:

  • Different pin assignment: Whereas Noctua fans use the standardised pin assignment for PC fans (see this FAQ for details), some network devices use different assignments. For example, some devices have the power and GND or rpm and PWM pins swapped. Therefore please carefully verify that your device uses the same pin assignment as standard fans. Experienced users may also change the pin assignment by cutting and resoldering the fan cables, but please note that this will void your Noctua manufacturer’s warranty.
  • Different pin functions: Noctua fans use the standardised pin functions for PC fans (see this FAQ for details); however, some network devices use fans where certain pins serve a different function. For example, some devices use the RPM pin for “power good” signals. Therefore please carefully verify that your device uses the same pin functions.
  • Firmware speed control: Some network devices demand a certain maximum or minimum fan speed. If the new fan doesn’t have the same or similar maximum or minimum speed, the device may display errors or even shut down.
  • Different starting voltage: Most network devices use voltage-based speed control. If the new fan has a higher starting voltage than the original fan, it may not start up right away. This may lead the device to display errors or even shut down because it suspects a fan failure.
  • Different power draw: Some network devices monitor the fan’s power draw. If the new fan has a lower power consumption than the stock fan, the device might display errors or even shut down.

Please note that most network device manufacturers don’t provide detailed documentation regarding fan compatibility and control, so users who want to replace the fans of their devices usually have to rely on “How to” guides, blog and forum posts or video tutorials. Please also note that fan compatibility and control can vary from model to model and even from revision to revision even if the devices stem from the same manufacturer. As a result, it is important to make sure that the information or guidelines you rely on when replacing your fans are applicable to your specific model as well as your specific hardware and firmware revision.

Due to the possible issues listed above, Noctua recommends that only experienced users attempt to replace their pre-installed fans in network devices. Please note that since there are so many different devices and most of them lack documentation for aspects such as fan compatibility and control, Noctua customer support cannot assist you with compatibility issues when replacing pre-installed fans. Please contact your network device manufacturer for any questions regarding aspects such as the device’s pin alignment or fan monitoring and control.

Can I use Noctua fans in my system from Acer, Apple, Dell, HP, Lenovo or other major brands?

Noctua 12V fans comply with the established specifications for standard PC systems issued by Intel and AMD. Systems from Acer, Apple, Dell, HP, Lenovo or other major brands often deviate from these specifications e.g. by using proprietary fan headers, custom pin-alignments or pin-configurations, different methods of fan speed control, etc. This can lead to compatibility issues when using Noctua fans in systems from said brands. Some of these problems can be avoided with some technical knowledge, but especially BIOS related issues (e.g. errors or shutdowns due to low fan speed) can often not be resolved. As a result, Noctua does not officially support systems from Acer, Apple, Dell, HP, Lenovo or other major brands.

Can Noctua fans be used to replace noisy stock fans in NAS devices?

Noctua fans such as the 40, 60, 80, 92 or 120mm NF-A series models are ideal for replacing noisy stock fans in NAS devices in order to make them quieter and thousands of users have managed to significantly reduce the noise levels of their NAS units this way. However, while it is easy and straightforward to replace the fans in some cases, it can be very difficult in others, so Noctua strongly recommends that users carefully research if it is possible to easily replace the fan(s) of their NAS device before purchasing a Noctua fan for this purpose. Some of the common issues that can occur when replacing NAS fans are:

  • Different pin assignment: Whereas Noctua fans use the standardised pin assignment for PC fans (see this FAQ for details), some NAS units use different assignments.

Please note that most NAS manufacturers don’t provide detailed documentation regarding fan compatibility and control, so users who want to replace the fans of their devices usually have to rely on “How to” guides, blog and forum posts or video tutorials. For example, there are excellent video tutorials available for changing the fans in popular Synology NAS models (DS416j, DS1515+ and DS1812+ in English, DS416/DS415/DS916/DS216/DS214 and DS1515+ in German). Please also note that fan compatibility and control can vary from model to model and even from revision to revision even if the devices stem from the same manufacturer. As a result, it is important to make sure that the information or guidelines you rely on when replacing your NAS fan are applicable to your specific model as well as your specific hardware and firmware revision.

Due to the possible issues listed above, Noctua recommends that only experienced users attempt to replace their NAS fans.

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.

How should I clean my Noctua fan?

Fans inside computer cases tend to accumulate dust over longer periods of usage. In order to maintain maximum performance, please clean your fans regularly using a duster, slightly moist tissue or canned air. Please be careful not to use too much force in order to prevent any damage to the fan. Please do not use a vacuum cleaner as this may apply excessive force to the fan and do not put the fan under running water as water residues inside the motor may lead to short circuits.
In order to ensure flawless operation over many years of usage, Noctua’s premium grade SSO bearings are fully sealed to prevent the entering of fine dust particles. Please note that the fan is not designed to be taken apart by the user. Removing the impeller from the frame will break the sealing of the bearing and results in a loss of warranty.

How can I find out the direction of airflow and sense of rotation?

When looking at the fan so that the circular sticker with the Noctua logo is facing you, the direction of airflow is towards you and the sense of rotation is clockwise:

What pin configuration do Noctua 12V fans use?

All Noctua fans feature the standard pin-configurations set out in the Intel and AMD specifications. These standard pin-configurations are used on most mainboards and fan controllers today:

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).
