Flow Acceleration Channels
The NF-A4x10 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
|
Reduced motor hub size
Thanks to its streamlined, compact motor design, the NF-A4x10's motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10's superior airflow and pressure performance.
|
AAO frame
Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan's performance/noise efficiency.
|
Stepped Inlet Design
Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.
|
Inner Surface Microstructures
With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
|
Integrated Anti-Vibration Pads
Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.
|
Smooth Commutation Drive 2
The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-A4x10 remarkably quiet even at very close distances.
|
SSO2 Bearing
The NF-A4x10 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.
|
Low-Noise Adaptor for full flexibility
The NF-A4x10 FLX (Flexibility) is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 4500 to 3700rpm so that it can be fine-tuned for superior airflow or maximum quietness.
|
3 to 2-pin Adaptor and Polarity Protection
The NF-A4x10 comes with an adaptor from 3-pin Molex to the 2-pin connectors used on many graphics cards or network and storage devices. An integrated diode provides polarity protection on 2-pin connections.
|
OmniJoin™ Adaptor Set
Many devices featuring 40mm fans use proprietary fan headers, so the NF-A4x10 comes with Noctua's OmniJoin™ adaptor set. Just cut the original fan's cable, fix it to the adaptor using the supplied 3M Scotchlok™ connectors and you can plug the NF-A4x10 to proprietary fan headers!
|
Extensive cabling options
The fan's short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved.
|
6-year manufacturer’s warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A4x10 features an MTTF of more than 150.000 hours rating and comes with a full 6-year manufacturer's warranty.

NF-A4x10 FLX Review
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-A4x10 FLX Review
Cijene manjih (A4x10/A6x25/A9x14 –
12,90/14,90/16,90€), kao i većih 140mm modela
(21,90€) su uglavnom u skladu s dosadašnjom politikom
Noctua proizvoda, koja se i dalje bazira na principu –
kvaliteta prije svega, uz odgovarajuću cijenu. Nakon svega
viđenog, zaista im ne možemo puno zamjeriti na tome, s
obzirom na sve prednosti njihovih proizvoda iz nove A-serije za
koje imamo gotovo isključivo riječi hvale.
|
||||||
|
Test verdict: "Noctua nam je ovom prilikom priredila mnoga iznenađenja po
pitanju novih proizvoda raznih veličina i namjena. Od
minijaturnog 40mm A4x10 modela, preko A6x25 i A9x14, pa sve do
140mm inačica, svaki od testiranih ventilatora odaje onu
poznatu Noctua kvalitetu i uglađenost u radu uz visoku
funkcionalnost i bogatu dodatnu opremu. Za svakoga ponešto, bi
možda bio najslikovitiji opis nove A-serije ventilatora, a
što se nas osobno tiče, itekako bismo voljeli vidjeti par
140mm ULN modela i u našem testnom računalu. Za korisnike
koji zahtijevaju veliku efikasnost i relativno umjeren nivo buke,
tu su naravno A14 FLX i A15 PWM modeli, koji svojom
fleksibilnošću, elegantnim radom ali i visokom
kvalitetnom izrade itekako zaslužuju našu preporuku."

NF-A4x10 FLX Review
Hemos probado los tres ventiladores y gratamente nos ha sorprendido su bajo nivel de ruido generado. El modelo de A4x10 es el único mínimamente más audible, pero por sus altas revoluciones es normal.
Los modelos de 40 y 60 mm son perfectos para sistemas embebidos que requieren un ventilador para la extracción de aire, así como para los amantes del modding que deseen refrigerar zonas de su PC de menor superficie.
El modelo de 90 mm es ideal para equipos HTPC con disipadores de perfil bajo, que lo verán aún más reducido al cambiar los habituales ventiladores de 25 mm de grosor por este de 14 mm.
|
||||||
|
Test verdict: "Los ventiladores Noctua Serie-A ofrecen en formato compacto el rendimiento esperado por un ventilador de esta prestigiosa marca: gran flujo de aire a un mínimo nivel sonoro. Su uso está limitado a necesidades concretas, por lo que gran parte de los usuarios no tendrán necesidad de ellos. Sin embargo, los que requieran productos de estas dimensiones agradecerán en gran medida el lanzamiento de estos ventiladores tan eficientes por parte de Noctua."

NF-A4x10 FLX Review
Ufak boyutlardan ötürü fan motoru neredeyse çerçevenin
yarısını işgal ediyor. Pervane ufak olunca devir iyice
yükseliyor ve 4500 oluyor ama bu durumda gürültü sadece 17.9 dBA ve
benzer fanlara kıyasla kat kat daha sessiz! Akım ise sadece 8.2 m³/h ama
normal. LNA filtre eklenirse hız 3700 devire, gürültü 12.9
dBA’e ve akım 6.6 m³/h değerine iniyor. Her iki modda da
aşırı sessiz.
|
||||||
|
Test verdict: "En yüksek güç tüketimi 0.6
Watt ve çalışma gerilimi 12 Volt olan fanın kullanım
ömrü en az 150 bin saat. 6 sene garanti bu model için de
geçerli. Daha kalın fan kullanan cihazlarla da uyumlu olması avantaj
sağlıyor." (Görkem Yildirimy, PCkoloji.com)

NF-A4x10 FLX Review
Le ventole Noctua della nuova serie A, sono state veramente all’altezza delle nostre aspettative, qualità impeccabile ed una longevità eccezionale. Gli appassionati potranno utilizzare queste ventole per una durata di oltre 150.000 con una garanzia sul prodotto di ben 6 anni. Come tutte le fan delle varie serie, sono curate minimamente sotto ogni punto di vista.

NF-A4x10 FLX Review
Dall’immagine si evince che, anche se siamo davanti a delle ventole molto piccole, la potenzialità che presentano è notevole anche rispetto alla sorella più grande da 92 mm, facendo registrare la stessa temperatura dell’hard disk utilizzando il modello A6x25 e, la ventola più piccola soltanto un grado di differenza rispetto alle sorelle più grandi. Segnaliamo infine la poca rumorosità di tutti e tre i modelli, confermando di fatto le specifiche proposte dall’azienda.
|
||||||
|
Test verdict: "Come da copione, anche con queste nuove ventole Noctua non ci ha delusi, proponendo prodotti che anche se di piccole dimensioni svolgono bene il proprio lavoro sia per prestazioni che la qualità; tutti e tre i modelli sono ideali per chi cerca prestazioni ottimali per il proprio sistema senza tralasciare la rumorosità."

NF-A4x10 FLX Review
All in all, these products are well built, well designed, and are able to achieve specs that by-and-large merit the premium price asked of them. None of the tested fans exhibited loud operation, and the included accessories ensured that the fans can be used in many different systems.
|
||||||
|
Test verdict: "It is typical for high-end or “luxury” goods to embrace a brand, style, or ethos, and Noctua does precisely that with their distinctive color scheme. The rest comes down to performance, though, and while you’ll pay top dollar to install a Noctua fan in your build, we’re hard-pressed to imagine how anyone will find themselves disappointed."

NF-A4x10 FLX Review
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.

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.

How much torque should be used for fan screws?
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.

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?
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.
How can I find out the direction of airflow and sense of rotation?
What pin configuration do Noctua 12V fans use?
Can I paint my Noctua fan in order to change its color?
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 I run Noctua 3-pin fans on 4-pin PWM connectors and use my mainboard’s automatic fan controller?
