Version 5V

Version 5V

De nombreux périphériques de stockage ou orientés réseau utilisent des ventilateurs 40mm sous un voltage de 5v. En offrant le voltage adéquat et grâce au kit d'adaptation OmniJoin™ qui assure une parfaite compatibilité avec les différents connecteurs de ventilation du marché, le NF-A4x10 5V est idéal pour remplacer les ventilateurs 5v 40mm bruyants ou hors d'usage.
Canalisateurs de flux (Flow Acceleration Channels)

Canalisateurs de flux (Flow Acceleration Channels)

La turbine du NF-A4x10 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.
Moyeux de taille réduite

Moyeux de taille réduite

Grâce à une conception plus profilée et compacte du moteur, le moyeu du NF-A4x10 est de taille plus réduite comparée à celle des ventilateurs 4cm traditionnels. En augmentant de fait la surface des pales, le NF-A4x10 améliore significativement le niveau de pression ainsi que le flux.
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.
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-A4x10 reste très discret même à proximité.
Roulement SSO2

Roulement SSO2

Le NF-A4x10 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.
Adaptateur 3 broches / 2 broches et protection de polarité

Adaptateur 3 broches / 2 broches et protection de polarité

Le NF-A4x10 est livré avec un adaptateur permettant de passer d'un MOLEX 3 broches à un connecteur 2 broches généralement disponible sur de nombreuses cartes graphiques, cartes réseaux ou disques durs. Une diode intégrée assure la protection de la polarité sur les connecteurs 2 broches.
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-A4x10 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-A4x10 au connecteur propriétaire dédié à la ventilation.
Nombreuses options de câblage

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 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-A4x10 affiche un MTTF de plus de 150 000 heures de test et se voit assorti d'une garantie constructeur de 6 ans.

NF-A4x10 5V test

Después de probar los modelos NF-A6x25 PWM, NF-A6x25 FLX, NF-A4x10 FLX y NF-A4x10 5V nos dan ganas de dejar un ventilador en nuestras placas pasivas, pero preferimos no hacerlo, como ya sabéis nos gustan los sistemas pasivos. Ciertamente es estos productos pueden ofrecen una mejora térmica en nuestros dispositivos si vamos a exprimirlos y además no nos molestan con ruidos. Si tenemos algún modelo pasivo con problemas térmicos añadirle un pequeño ventilador bien dimensionado siempre es una solución, sobretodo si tienen la calidad de estos modelos.
Verdict du test: "Los recomendamos sin ninguna duda para quien quiera mejorar el rendimiento de su miniPC o AndroidPC con problemas térmicos." (Joaquin Prida Trujillo, AndroidPC.es)

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.
Verdict du test: "Sve u svemu, Noctua uspješno nadograđuje svoj lineup i kupci će kao i uvijek biti vrlo zadovoljni." (Krešimir Matanović, PC Ekspert)

Noctua is always striving to create a better balance between noise and performance. Noctua is always pressing forward and advancing the engineering behind the products released. If you ask anyone who has quiet, high performance fans for computing, Noctua is going to be on the tip of the tongue. I believe Noctua will continue to strive for perfection by releasing new products. These fans are just a set of the many that have come before and the many that will continue to be released.
Verdict du test: "If you want less sound humming from your computer case and better cooling, look no further. Even with their size, these fan models with their high static pressure are up to the challenge. As with all of its products, these fans come with a six year warranty, which is longer than some fans last all together." (Allen Woo, OverclockersClub.com)

NF-A4x10 5V 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)

NF-A4x10 5V test

Last year, Noctua gave us 120 and 140mm fans with a technology feature list that they struggled to fit on the back of the packaging. The designers had improved the bearings, the fan blades, the frame, mounts - basically everything about their previous (and very successful) design to further improve the efficiency to noise ratio. At the time it was great news for those looking to silence their medium to large sized PCs. Now there is also good news for builders looking to maximise the airflow whilst minimising the noise of their mini ITX builds with the NF-A8 and NF-A9 series of fans that include all the bells and whistles of their larger siblings. We also tested a pair of 40mm fans for chipsets and other really compact applications.
Verdict du test: "If silence is critical to your build, the Premium series from Noctua is worth the price and a safe option." (Phil Carroll, PCGamers.net.au)

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.
Verdict du test: "Ventole per ogni tipo di esigenza. Noctua con la serie NF-A ha pensato proprio a tutti e a tutto proponendo prodotti di altissima qualità e tecnologia mantenendo un ottimo rapporto qualità/prezzo. Decisamente apprezzata la cura dei dettagli e del bundle che rendoni queste ventole il TOP DI GAMMA sul mercato." (Davide Torno, QWERTYmag.it)

NF-A4x10 5V test

Pored ove dvije kompletno nove serije ventilatora, Noctua je izbacila po još nekoliko modela koja je upotpunila postojeću garnituru popularnih NF ventilatora koji nas godinama prate, kako u njihovom standalone portfelju i ponudi, tako i na njihovim high-end hladnjacima za procesore. Riječ je modelima manjih veličina, odnosno promjera ventilatora, počevši od 90 mm, pa sve do 40 mm preko 80 mm i 60 mm modelima. Ovi najmanji 40 mm ventilatori izgledaju poput kakvog privjeska za ključeve, ali neka vas ne zavaraju njihove gabariti, jer ovi mališani mogu dostaviti visok protok zraka zahvaljujući vrlo visokim okretajima od 4500 okr/min. Modeli nešto većeg promjera su ipak dosta “mirniji” i pružaju veći protok zraka kao i statički pritisak. Baš kao i sa ostatkom klasičnih NF modela, ovdje imamo nekoliko standardnih varijacija na temu, počevši od FLX, ULN i PWM pod-modela, uz svu klasičnu dodatnu opremu, te različiti broj okretaja. Izgleda da je Noctua prepoznala tržište okrenuto prema ovim ventilatorima manjeg promjera, vjerojatno prvenstveno radi sve veće popularnosti slaganja malih i jakih, ali prije svega tihih računala kojima također trebaju visoke performanse hlađenja.
Verdict du test: "Možda izgledaju poput igračaka, ali novi NF-A8 / A9 / A4 ventilatori dostavljaju vrhunske performanse čak i u malim dimenzijama " (Matej Majstorović, Vidi.hr)

W każdym z kompletów znajdujemy wszystkie niezbędne akcesoria, dzięki czemu możemy wykorzystać je do różnych zastosowań. Jedne z nich lepiej sprawdzą się z tyłu, a inne z przodu obudowy. Modele NF-A8 ULN, NF-A8 FLX oraz NF-A9 FLX wyróżniają się bardzo cichą pracą, która zadowoli każdego, nawet najbardziej wyczulonego użytkownika. Pozostałe wentylatory są głośniejsze, ale nie zapominajmy o możliwości użycia odpowiednich reduktorów obrotów.

What pin configuration do Noctua 5V fans use?

The pin configuration of Noctua 5V fans is identical to 12V fans:

5v pin configuration

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.

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.

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.

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 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 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:

P14

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

Noctua fans such as the 40, 60, 80 or 92mm 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 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 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.
