Le NF-A8 est un ventilateur silencieux premium de 80mm bénéficiant de nombreuses optimisations. Doté d’un cadre AAO (Advanced Acoustic Optimisation) et jouissant d’un design aérodynamique étudié (avec par exemple les Flow Acceleration Channels), le NF-A8 repousse encore plus loin les limites du refroidissement silencieux atteintes par le célèbre NF-R8. La version FLX autorise, grâce à l’utilisation d’un adaptateur faible bruit (LNA), un réglage de la vitesse à 2000/1650 ou 1200 tr/min. Ce dispositif garantit ainsi une flexibilité totale au travers d’un réglage sur-mesure de la vitesse de rotation pour une ventilation renforcée ou bien un fonctionnement quasi-inaudible. Il bénéficie de la qualité de construction Noctua et est doté du roulement SSO2 Bearing, la référence incontournable, qui assure un fonctionnement sans faille ; il devient ainsi l’arme absolue des utilisateurs les plus exigeants.

Digne successeur du célèbre NF-R8
Le ventilateur NF-R8 est devenu une référence incontournable, dans l'univers PC, pour les passionnés recherchant un ventilateur 80mm de qualité premium. Grâce à des optimisations aérodynamiques permanentes, le NF-A8 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)
La turbine des NF-A8 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
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
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
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
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
Les NF-A8 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
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-A8 reste très discret même à proximité.
|
Réglage à 3 vitesses pour une flexibilité totale
Donnant accès à des réglages de vitesse de 2000, 1650 et 1200 rpm grâce aux adaptateurs fournis (faible bruit et ultra faible bruit), le NF-A8 FLX (FLX pour Flexibilité) offre une grande souplesse de réglages en termes de flux d'air et de silence.
|
Nombreuses options de câblage
Si le câble principal d'alimentation du ventilateur est court (20 cm) afin de limiter l'encombrement dans les utilisations traditionnelles, celui de 30cm est fourni pour résoudre les problèmes éventuels de distance. Les deux câbles sont entièrement gainés.
|
Garantie Fabricant de 6 ans
La réputation des ventilateurs Noctua n'est plus à faire tant pour leur qualité que pour leur étonnante longévité. Comme pour tous les modèles Noctua, les NF-A8 bénéficient d'un MTTF de plus de 150 000 heures de tests et bénéficie d'une garantie totale fabricant de 6 ans.

NF-A8 FLX test
+ They are quiet fans.
+ They have pretty good output for being so quiet. + They come in resilient packaging. + They come with well-chosen accessories. |
||||||
|
Verdict du test: "Noctua started with really good fans, and made them better. One thing that strikes you if you handle the old fans is that they are very good fans, so it makes sense that Noctua still sells them in their redux line. But these A-Series fans are even better, and well can they join their big brothers in the A-Series lineup." (Ed Hume, Vortez.net)

NF-A8 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)

In questa recensione ci siamo realmente resi conto di quanto Noctua sia attenta ai dettagli e alla cura dei propri prodotti anche in delle “semplici” ventole che poi, in questo caso specifico, semplici non sono visto l’elevata cura nella produzione e nelle tecnologie adottate.
Ci ha stupito moltissimo il fatto di ritrovare tutte le tecnologie citate nell’introduzione anche nelle ventole di dimensione ridotta come le NF-A4. Siamo decisamente soddisfatti sia dalle prestazioni in termini di efficienza/rumore, sia dal bundle che dai prezzi decisamente in linea con quelli di altri produttori ma assolutamente superiori in termini di caratteristiche e prestazioni.
Attribuiamo a tutta la NF-A Series il premio Gold Award per l’innovazione tecnologica e la cura dei particolari che L’azienda ha dimostrato in questa serie di ventole super-efficienti.

NF-A8 FLX test
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)

Como podemos comprobar, los modelos de 80 y 92 mm son completamente silenciosos, pero el modelo de 40 mm es algo ruidoso como cabe esperar para sus 4500 RPM máximas. Es curioso además ver el gran flujo de aire que ofrece el modelo A4, pues es capaz de moverse solo con gran facilidad.
|
||||||
|
Verdict du test: "Los ventiladores Noctua NF-A4/A8/A9 demuestran una vez más el buen hacer de Noctua, pues ofrecen un gran rendimiento con una sonoridad mínima. Además, llegan acompañados de un excelente kit de accesorios, algo de lo que pocas marcas pueden presumir." (Iván Martínez, El Chapuzas Informático)

NF-A8 FLX test
Stock performance shows a 3 degree drop with the A9 fans on heatsink use and up to 2 degrees under FPU only loads. Noise performance is superior in the NF-A9, despite the higher RPM with a smoother PWM operation and 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.
Ultimately each fan size has its own application depending on the chassis or heatsink applied to, although the smaller A4 5V fan is more suitable for storage cooling but will not look out of place as a chipset or spot cooler as well, especially the 12V version for added flexibility. The 92mm and 80mm A9 and A8 have a very balanced performance as both heatsink fans or case fans with their wide fan blade and excellent static pressure performance. The further lowered noise compared to the B9 and R8 series is a welcome change because the original fans were not particularly troublesome at all when it came to noise either. The integrated padded corners also work very well for noise dampening, especially when positioned as a “pull” fan since there is an added space that minimizes high pitched noises typically present in high-RPM performance fans when placed in this position.
|
||||||
|
Verdict du test: "As with all Noctua fans, they come with premium pricing as they come in premium packaging and feature set so they are not easily affordable. The good thing is that the 6-year warranty found on larger Noctua fans also apply to the A9, A8 and A4 series, as well as the premium accessories that come out of the box."

NF-A8 FLX test
Niveau nuisances sonores, notre NF-A8 dégomme littéralement la ventilation de base de notre NAS N2810. Avec une valeur de 37,7 dBa sans LNA ou 36,5 dBa avec contre les 45 dBa de base, les chiffres parlent d'eux-mêmes ! Par contre, la valeur constante s'explique par l'absence d'une gestion PWM, ce qui implique une vitesse constante du ventilateur.
Réducteur de section carré
Concernant les températures, nous avons le même constat. Le Noctua fait beaucoup mieux, malgré notre montage quelque peu bancal qui génère beaucoup de fuites.
|
||||||
|
Verdict du test: "Comme à leur habitude, Noctua, avec le NF-A8, ne laisse rien au hasard, le silence prime avant tout. Ils sont pratiquement inaudibles, même sans LNA. Le fabricant fait donc encore une fois très fort, et prouve donc que la technologie se met au service du silence, même pour les petits formats !" (Jean Baptiste Schmitt, ZeDen.net)

Los ventiladores Serie A de Noctua están recomendados por Hardaily como ventiladores suplementarios (versiones no PWM), sustitutos de ventiladores más modestos o viejos para lograr mejor ventilación. Las versiones PWM son altamente recomendadas por Hardaily como sustitutos en los disipadores o radiadores y para que tengan autocontrol, ya que son los más potentes también. Todos ellos son perfectamente válidos para torres, servidores, para disipadores o incluso radiadores, siempre que sean compatibles con las medidas estandarizadas de 4 8 y 9cm. Todos estos ventiladores de Noctua son de los más duraderos y resistentes del mercado.

Which Noctua fan or CPU cooler should I buy? How to choose the right model?
My Noctua 3-pin fan starts to spin when the PC boots but then stops, what is wrong?
- 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.
- 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!
How much torque should be used for fan screws?
Can I use Noctua fans in my system 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?
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.
What pin configuration do Noctua 12V fans use?
Can I disassemble my fan for cleaning (or other purposes, e.g. painting)?
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 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.
