Bénéficiant d’une conception aérodynamique avancée incluant les Flow Acceleration Channels et le cadre AAO Noctua, le NF-A4x20 5V est une déclinaison 5v du fameux ventilateur silencieux haut de gamme et hautement optimisé 40x20mm. L’intégration de la technologie Smooth Commutation Drive associée au roulement de référence Noctua SSO2 garantissent un fonctionnement souple et une excellente stabilité sur le long terme. Complété d’un câblage modulaire, du kit OmniJoin™ Adaptor Set et bénéficiant d’une garantie fabricant de 6 ans, le NF-A4x20 5V s’impose comme la solution premium idéale pour les applications 5v.

S’agissant d’un ventilateur 5v, le NF-A4x20 5V ne peut fonctionner sous une tension de 12v et toute utilisation avec une source de courant 12v (c’est par exemple le cas des connecteurs de ventilation présents sur les cartes mères pour PC) détériorera le ventilateur.
Détails
Format 40x20 mm

Format 40x20 mm

Comparé au célèbre Noctua NF-A4x10, le NF-A4x20 est deux fois plus épais, ce qui permet d’accroître les performances en terme de pression statique. Le NF-A4x20 est ainsi idéal pour les applications exigeant un flux de résistance élevée.
Version 5V

Version 5V

De nombreux appareils, tels que ceux dédiés au stockage ou à la gestion de réseaux, intègrent des ventilateurs 40mm fonctionnant sous 5 volts. Parce qu’il fonctionne sous une telle tension et qu’il est livré avec un kit d’adaptation OmniJoin™ lui permettant de se greffer à des connecteurs propriétaires, le NF-A4x20 5V constitue la solution de remplacement parfaite pour les ventilateurs 40mm 5v bruyants ou défectueux.
Protection à l’inversion de polarité

Protection à l’inversion de polarité

De nombreux appareils pourvus de ventilateurs 5V utilisent des connecteurs propriétaires. Sachant que le sens de connexion n’est pas toujours précisé dans les documents techniques, le ventilateur est équipé d’une diode de protection à l’inversion de polarité. Vous êtes ainsi prémuni de tout incident en cas de branchement inversé accidentel.
Canalisateurs de flux (Flow Acceleration Channels)

Canalisateurs de flux (Flow Acceleration Channels)

La turbine du NF-A4x20 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-vibrations intégrés

Silentblocs anti-vibrations intégrés

Les silentblocs anti-vibrations intégrés, fabriqués à partir de silicone extra-souple, permettent de limiter la transmission des vibrations minute tout en assurant une parfaite compatibilité avec les vis et systèmes de fixations standards.
Kit d'adaptation OmniJoin

Kit d'adaptation OmniJoin

Compte tenu du fait que de nombreux produits équipés de ventilateurs 40mm sont pourvus de connecteurs spécifiques pour les raccorder, le NF-A4x20 est livré avec un kit d'adaptation OmniJoin. Il vous suffit de couper le câble de votre ventilateur d'origine, de le raccorder à l'adaptateur en utilisant les connecteurs Scotchlok 3M™ founis. Vous pouvez alors brancher votre NF-A4x20 au connecteur propriétaire dédié à la ventilation.
Roulement SSO2

Roulement SSO2

Le NF-A4x20 se voit doté 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.
Garantie Constructeur de 6 ans

Garantie Constructeur de 6 ans

Les ventilateurs Noctua sont connus pour leur qualité irréprochable et leur étonnante longévité. Comme tous les ventilateurs de la marque, le NF-A4x20 affiche un MTTF de plus de 150 000 heures de test et se voit assorti d'une garantie constructeur de 6 ans.

NF-A4x20 5V test

Noctua ha lanzado una nueva colección de productos de gama alta para el apartado de refrigeración que, como siempre, dejan a la marca en excelente lugar. Por un lado, tenemos los ventiladores Noctua NF-A12x15, una excelente alternativa para disipadores slim o chasis compactos donde no tengan cabida los tradicionales de 25 mm de grosor. Los NF-A20 son una opción para chasis que permitan los modelos de 200 mm, aunque no ofrecen una gran mejora frente a modelos de 120 mm. Mientras, los NF-A4x20 son un sustituto ideal para dispositivos ultracompactos, ya sea por reparación o para mejorar su sonoridad. Por si fuera poco, todos ellos ofrecen nada menos que 6 años de garantía, por lo que tenemos ventiladores para rato. Además, Noctua siempre busca suplir todas las necesidades de sus clientes y para ello lanza algunos accesorios como los que hemos visto, los se unen a un inmenso portafolio que podemos consultar aquí.
Verdict du test: "Como no podía ser de otra forma, desde del El Chapuzas Informático le otorgamos el Galardón de Platino a los ventiladores Noctua NF-A12x15, NF-A4x20 y NF-A20 y los nuevos accesorios, productos todos ellos de la más alta calidad.

NF-A4x20 5V test

We have no doubt about the top quality of Noctua products. Each one of them is well designed. Even the package is exceptional. Most manufacturers are missing these little things that count while Noctua provides package with everything you may need for installation. Long years of designing and engeneering gave great results. Where you could think there can’t be done much more, Noctua proved that even the best products can be improved. New A series fans are the best in their class and it’s hard to find anything similar on the market. Even though new fans are considered as “slim”, they provide top air pressure while keeping low level of generated noise. Perfect balance for all who expect the best from their fans.

NF-A4x20 5V test

Veliki NF-A20 i u PWM i U FLX verziji košta oko 33 € što je korektna cijena za veličinu ventilatora, svu opremu koju donosi i na kraju krajeva vrlo dobre performanse uz ne previsoku buku. Kvaliteta izrade je visoka, materijali odlični a tehnologije jamče dugovječnost – kao i šest godišnje jamstvo uostalom. NF-A12x15 su po cijeni od 24 € pogodni za ugradnju u skučenija HTPC kućišta i na manje hladnjake, a obavezno ih se treba malo usporiti jer su na visokim okretajima čujniji. “Propuh” koji stvaraju je vrlo dobar i na nižim okretajima. A4x20 je u svim verzijama oko 20 €. Visoka je to cijena za 40-milimetarske ventilatore, no zbog kvalitete izrade, jamstva i ponajprije velike kompatibilnosti i mogućnosti prilagodbe isplati se platiti i tako visoki iznos. Ventilatori jesu bučniji pri visokim okretajima, no za kakav komad mrežne opreme koji je u ormaru to i nije bitno, a koncentrirana je zračna struja visoka i moćna. NA-SAV3 i SAV4 su po 11.50 € za što kupac dobiva kvalitetu, kompatibilnost s velikim brojem ventilatora i 16 komada nosača za po četiri ventilatora. NA-FC1 je svestran i kvalitetan kontroler za do tri ventilatora koji je moguće napajati direktno iz SATA Power konektora, pa može kontrolirati i jače ventilatore, no nije jeftin – 15 €. I za kraj, NA-SAC5 adapter koji može biti iznimno koristan za jače ventilatore koji se direktno napajaju iz SATA Power konektora i tako ne opterećuju ploču. Negativna je jedino cijena od oko 8 €.
Verdict du test: "Noctua koristi svoju veliku ekspertizu u izradi sve boljih ventilatora iz godine u godinu. Novosti za ovu su tri varijante koje smo u ovom članku pokazali i svaka je od njih posebna, a to uključuje i sve izvedenice pojedinih ventilatora. [...] Svi Noctuini proizvodi su kao uvijek korisni i zaslužuju visoke preporuke, a jedino što ima zapravo možemo zamjeriti je nešto viša cijena za naše hrvatske (prazne) džepove."

NF-A4x20 5V test

El ofrecer un buen airflow es algo muy importante y los sistemas NAS y router, suelen flojear en la refrigeración, por eso es muy importante contar con un buen ventilador. La refrigeración de estos componentes normalmente es muy mala y por eso, se requiere mejorar con ventiladores de alta eficiencia y que ofrezca un gran flujo de aire. Sobre todo estos componentes suelen sufrir en verano, que es cuando se necesita más potencia y un gran flujo de aire. Los ventiladores Noctua NF-A4x20, en sus cuatro versiones, son de tan solo 40mm, pensando no solo en sistemas compactos de reducidas dimensiones, sino también en los NAS y los routers, los cuales suelen implementar ventiladores de mala calidad, muy ruidosos y que suelen durar poco tiempo.

NF-A4x20 5V test

Jumping right into things and as you would expect from Noctua, the performance of these products is second to none. Given their respective sizes, all of these fans create a decent amount of airflow when tested in an open world environment, i.e. not in a case but just on a table. As mentioned I have actually used the NF-A4x20’s on a 3D printer in the past and was a great upgrade from the cheap fans that it had originally come with. While some may criticize the colour scheme, I don’t recall hearing very many people talk ill of the performance of any Noctua product. These fans all offer a great amount of airflow, again, for their respective sizes and remain as quiet as possible when doing so. The massive NF-A20’s are for those who need the most airflow possible but do make sure your case or where ever you are using them can cater to their 20cm sizes. The A4x20’s and A12x15’s are for when space is crucial and you need the most from your fans. The small 20mm and their unique size can come in handy for a number of scenarios. The added airflow to say the intake vents on a lot of the newer PC gaming cases is sure to help keep your components as cool as can be. The A12x15 are slimline and will surely come in handy for those looking to go with a push/pull configuration on any radiators for CPU and GPU cooling. Too many times have I seen a case where you can’t install a push/pull configuration due to space restrictions, well no more! Noctua’s A12x15 are sure to help you overcome this issue with ease. All of these fans in their own rights are equally useful and offer the same great performance we have come to know and love from Noctua. As far as the accessories go, they all perform as good as one could hope for. My Favourite was probably the fan controller as it allowed me to control my 2 front intake fans and 1 exhaust fan with ease. During the day I like them silent, but when the headphones come out and the game comes on, it’s time to turn the fans up a bit and this was done easily and quickly. The Anti-vibration mounts are nice as well. Not only do they reduce noise from vibrations, they allow you to install and remove your fans with ease which is always a plus when it comes time to clean them. Lastly, the 4-pin PWM to SATA power cable is a great addition to any build as it will allow you to connect a fan to any extra SATA power cables you have coming from your power supply. Those with motherboards that don’t have a lot of fan headers and are not keen on using a controller will find these very useful.
Verdict du test: "If you want the best of the best and you want it to last you for as long as you’ll need, then Noctua has the answer for you. These products on review here today are well worth their individual price tags and you shouldn’t be put off paying a bit extra for them considering everything they have to offer."

Another issue that I ran into is the fact that these fans are so incredibly quiet that I was not able to pick them up with my dB meter. The ambient noise in my condo is above that of the fans, and the only one I can audibly hear over anything else any more than a foot away is the 120 mm fan. At 70% speed (thanks again for the awesome tool, Noctua!), I was only able to hear it at the same distance as the other fans. It becomes audible above 70%, but not intrusively. I have an absolutely maddening obsession when it comes to rig silence, so for me to say this, it tells you something. Even the 40 mm fans did me very proud indeed. I was able to hear them a very small amount, but given that they are spinning at 5000 RPM (I may or may not have tried to stick my finger in to slow it down…), it blew me away with its noise level. Simply phenomenal acoustic levels.
Verdict du test: "If you can afford the premium price that comes attached with Noctua products, and you don’t mind their browny-beige color scheme, then they are absolutely one of the best fan makers in the world. I honestly forgot how quiet and premium their fans were until I got my hands on the care package that they sent over." (Brendan van Varik, PureOverclock.com)

Hoy hemos presenciado como Noctua lo ha vuelto a hacer, las prestaciones de sus nuevos productos continúan siendo la referencia que siempre han sido, pero hay otras cosas que también van a continuar. Frente a las grandes prestaciones tradicionales de Noctua hay otro aspecto que también se mantiene, este nivel de calidad no es barato, desde los 30€ que cuesta el ventilador de 200mm, el NF-A20. El adaptador SATA por 8€, el controlador por 20€ o los sorprendentes 15€ que cuesta el pequeño ventilador de 40mm, pasando por los más razonables 20€ por el ventilador más tradicional de 120mm. No obstante hemos de hacer hincapié en algo que solemos decir en Tecnogeekies bastante a menudo, aunque 20€ pueden parecer muchos, especialmente solo por un ventilador, su calidad y su durabilidad nos hacen recomendar esta marca siempre que vuestro presupuesto os lo permita.

En ce qui concerne le niveau sonore la marque a bien travaillé, les NF-A4 se démarquent de ce que l'on trouve habituellement avec une discrétion très apréciable, les NF-A12 quant à eux sont très silencieux au minimum mais plutôt bruyant une fois alimentés en 12V, rien de bien grave cela dit vu les adaptateurs livrés. Les plus gros NF-A20 sont également silencieux que ce soit au minimum ou au maximum. Proposés à un tarif allant de 7.90€ pour les NF-A4 à 29.90€ pour les NF-A20 en passant par 19.90€ pour les NF-A12x15 ils sont encore une fois réservés à ceux qui ne se satisfont que de produits haut de gamme, ils ne seront clairement pas déçus.

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 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.

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.

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 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.

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.

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 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.

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.
