Digne successeur du célèbre NF-B9

Digne successeur du célèbre NF-B9

Le ventilateur NF-B9 est devenu une référence incontournable, dans l'univers PC, pour les passionnés recherchant un ventilateur 92mm de qualité premium. Grâce à des optimisations aérodynamiques permanentes, le NF-A9 délivre une pression statique encore plus élevée ainsi qu'un rapport flux d'air/bruit encore meilleur comparé à son prédécesseur.
Canalisateurs de flux (Flow Acceleration Channels)

Canalisateurs de flux (Flow Acceleration Channels)

La turbine des NF-A9 est munie de canalisateurs de flux sur la face succion du ventilateur. L'accélération du flux générée aux extrémités des pales permet de créer une succion plus massive, moins dispersée, et accroit ainsi l'efficacité tout en réduisant les perturbations sonores liées aux vortex.
Cadre AAO

Cadre AAO

Les cadres AAO (Advanced Acoustic Optimisation) de Noctua sont équipés de silentblocs anti-vibrations et bénéficie d'optimisations exclusives permettant de repousser encore plus loin les limites de la performance et du silence : Stepped Inlet Design and Inner Surface Microstructures.
Conception en escalier de l'admission

Conception en escalier de l'admission

La conception en escalier de l'admission de Noctua ajoute une turbulence au flux entrant permettant ainsi un passage progressif d'un flux laminaire à un flux turbulent. Ce phénomène réduit les émissions sonores initiales, améliore la cohésion du flux et augmente la capacité de succion en particulier dans les environnements où l'espace fait défaut.
Conduit de contournement à microstructures

Conduit de contournement à microstructures

Les extrémités des pales évoluant à proximité de la surface intérieure du conduit (caractérisée par la présence d'une microstructure), la séparation des flux qui s'opère au niveau de la succion est quasi inexistante. Cette optimisation permet de réduire les émissions sonores liées au mouvement des pales, améliore le flux d'air ainsi que le niveau de pression.
Silentblocs anti-vibration intégrés

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.
Roulement SSO2

Roulement SSO2

Les NF-A9 se voient dotés de la célèbre référence du roulement Noctua : le SSO. Il s'agit ici de la toute nouvelle génération, encore plus optimisée. Le SSO2 est en effet équipé d'un aimant arrière plus proche de l'axe pour une meilleure précision, longévité et stabilité.
Smooth Commutation Drive 2

Smooth Commutation Drive 2

La toute dernière mouture du système SCD de Noctua garantit un fonctionnement tout en douceur grâce à l'élimination des variations de couple et des bruits de commutations. Par conséquent, le NF-A9 reste très discret même à proximité.
Réglage à 3 vitesses pour une flexibilité totale

Réglage à 3 vitesses pour une flexibilité totale

Donnant accès à des réglages de vitesse de 1650, 1250 et 1050 rpm grâce aux adaptateurs fournis (faible bruit et ultra faible bruit), le NF-A9 FLX (FLX pour Flexibilité) offre une grande souplesse de réglages en termes de flux d'air et de silence.
Nombreuses options de câblage

NF-A9 FLX test

As always, sound levels are superb with these fans. While my opinions are subjective, what I found was after 45 dBs, that’s when I felt a fan was getting too noisy. Nothing about the Noctuas sounded too loud while testing them even at max speed, but with the plethora of LNAs and ULNAs to add to the fans, even if you didn’t have a way to control the fans it was unlikely you couldn’t tone them down to where you would be happy with them.
Verdict du test: "Overall, I believe Noctua makes an excellent product. There really isn’t anything I can complain about except for the price, and even then the price is understandable. If you need good air flow, low noise and have a small form factor case that needs some better fans, I could definitely recommend what Noctua has to offer here." (Josh Jackson, PureOverclock.com)

After studying the Noctua A-series Premium fans for the last few weeks, I have begun to understand how each design feature performs their function. As noted in the following paragraphs, each feature adds to the overall function of noise reduction, therefore improving air flow and performance efficiency. The Noctua Advanced Acoustic Optimization Frame has anti-vibration pads in each mounting flange corner. This feature not only reduces vibration noise transferring from the fan, but also into the fan from wobbly case components. The Stepped Inlet Design on the fan case edge turns the air flow from laminar to turbulent, reducing the tonal intake noise. The Inner Surface Microstructures next cause a boundary layer to reduce suction side flow separation as the fan blade tips pass, reducing the blade passing noise with improved air flow. The Flow Acceleration Channels on the fan blades cause the outer blade region air flow to speed up, reducing vortex noise of the fan blades while improving efficiency. Moving the magnet of the Noctua renowned SSO Bearing closer to the axis of the bearing improves stabilization, precision and durability. All of these features and more are packaged with many accessories for each fan, plus Noctua provides a 6 year warranty.

Aside from the lower temperature, the A9 fans have a more “spread out” sound signature even though it is running at a higher RPM and has lesser high pitched noises across various speeds. The extra padded corners also help in giving extra space when positioned in a “pull” position minimizing noise. The smaller form factors and compact builds are much more common now than ever before with many users opting to build desktops that can be portable for LAN parties or for discreet integration in their living room as an HTPC. The A9 and A8 series fans fit these application well with excellent performance and low noise profiles that is even more flexible if need be. For storage or, spot cooling or component cooling in even tighter spaces, the A4 series offers a rare and impressive feature set that is above what most people would expect from something this small.
Verdict du test: "These A-series fans also enjoy the same set of low noise features and premium build quality that the other Noctua fan series provides, including the impressive 6-year warranty and extensive accessory package." (Ron Perillo, Modders-Inc.com)

Kvaliteta materijala i izrade je nešto na što Noctua posebno pazi a to se odrazilo i na ove nove modele. Performanse svih modela su u skladu s onime što deklarira proizvođač i kod Noctue se dobiva točno ono što se i plaća. PWM hladnjaci su po običaju na maksimalnom broju okretaja malo čujniji, no performanse se ne gube nimalo uz upotrebu L.N. adaptera pri čemu se buka ipak dosta smanji.

My Noctua 3-pin fan starts to spin when the PC boots but then stops, what is wrong?

Many mainboards are able to automatically regulate the fan speed of 3-pin fan via voltage based measures. However, due to limitations of this method it may occur that the mainboard reduces the voltage so much that the fan stops. 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.

I get a CPU fan error despite the fan is running!

Some mainboards display a CPU fan error when the fan speed falls below a certain threshold, e.g. 900rpm. If you want to run the fan below this speed (e.g. using the supplied U.L.N.A.), please adjust the threshold in the BIOS or disable CPU fan error warning.

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 independently from the second fan’s rpm signal.

How much torque should be used for fan screws?

Please use 0.6Nm to tighten fan screws. Make sure not to overtighten the screws as this may damage the fan frame.

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. For example, some devices have the power and GND or rpm and PWM pins swapped. Therefore please carefully verify that your NAS 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 NAS units 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 NAS device uses the same pin functions.
  • Firmware speed control: Some NAS 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 NAS 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 NAS device to display errors or even shut down because it suspects a fan failure.
  • Different power draw: Some NAS 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 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. Please note that since there are so many different NAS models 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 NAS fans. Please contact your NAS manufacturer for any questions regarding aspects such as the device’s pin alignment or fan monitoring and control.

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.

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 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!

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:

pin configuration

Can I paint my Noctua fan in order to change its color?

Since even small variations in the layer of paint can lead to an imbalance of the impeller, resulting in vibrations, higher noise levels, increased stress on the bearing and thus reduced lifespan, we do not recommend painting the fan. Please note that for the reasons stated above, painting the fan will void your warranty.

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.

Can I run Noctua 3-pin fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller?

You can simply connect our fan's 3-pin connector to the 4-pin PWM sockets of today's mainboards so that the fourth pin that transmits the PWM signal is left blank (due to the shape of the connector, there's no danger of reversing polarity). Some mainboards (e.g. current Gigabyte models) are capable of controlling fans not only via PWM, but also by adjusting the supplied voltage. In some cases, this may require you to change BIOS options like "Fan Control Mode" from "PWM" to "Voltage" or "Analog". Please consult your mainboard's manual in this regard. However, some mainboards use an "auto" setting by default that automatically chooses PWM or voltage based regulation according to the connected fan. Automatically controlling the fan speed may not possible on mainboards that pulse the power rather than lowering the fan voltage.
