Superando al premiado NF-B9
El ventilador NF-B9 de Noctua se ha convertido en la opción por excelencia entre los entusiastas de los PC que buscan ventiladores silenciosos de 80 mm de gran calidad. Gracias a su profunda optimización aerodinámica, el NF-A9 proporciona una presión estática más alta y un mejor índice de flujo de aire/ruido que el de su aclamado predecesor.
|
Flow Acceleration Channels (canales de circulación acelerada)
El rotor del NF-A9 dispone de Flow Acceleration Channels (Canales de Circulación Acelerada) por el lado de succión. Aumentando la velocidad del flujo de aire en las regiones cruciales exteriores de las aspas, esta medida reduce la separación del flujo en el lado de succión y resultando así en una mayor eficiencia y menor ruido de vórtice.
|
Marco AAO
Los marcos AAO (optimización acústica avanzada) de Noctua cuentan con almohadillas antivibración integradas, así como con el diseño de entrada paso a paso y las microestructuras de superficie internas (ambos propiedad de Noctua), que perfeccionan aún más la eficiencia sonora y el rendimiento del ventilador.
|
Diseño de entrada paso a paso
El diseño de entrada paso a paso de Noctua añade turbulencia a la entrada de aire para facilitar la transición de flujo laminar a flujo turbulento, lo que reduce el ruido de entrada tonal, mejora la adjunción de flujo e incrementa la capacidad de succión, especialmente en entornos con espacio restringido.
|
Microestructuras de superficie interna
Con los extremos de las aspas del ventilador en colisión con la capa límite creada por las Inner Surface Microstructures (microestructuras de superficie interna), la separación del flujo desde el lado de succión de las aspas mengua de forma significativa, lo que resulta en un ruido de paso entre las aspas menor, mejor flujo de aire y mayor eficiencia de presión.
|
Almohadillas antivibración integradas
Las almohadillas antivibración integradas, fabricadas en silicona extrasuave, minimizan la transmisión de las vibraciones por minuto, a la vez que mantienen la compatibilidad con todos los sistemas de montaje estándar y clips para ventilador utilizados en los disipadores.
|
Rodamientos SSO2
El NF-A9 dispone de los reconocidos rodamientos optimizados SSO de segunda generación de Noctua. Con los SSO2, el imán posterior está situado más cerca del eje para proporcionar mayor estabilidad, precisión y durabilidad.
|
Smooth Commutation Drive 2 (Unidad de Conmutación Suave 2)
La última versión del avanzado sistema Smooth Commutation Drive (Unidad de Conmutación Suave) de Noctua garantiza una suavidad de funcionamiento excelente ya que elimina variaciones del par y ruidos en los cambios del PWM. Es por eso que el NF-A9 es extraordinariamente silencioso incluso a las más reducidas distancias.
|
3 configuraciones de velocidad para una flexibilidad completa
Proporcionando configuraciones de velocidad de 1650, 1250 y 1050 rpm a través de los adaptadores Low-Noise y Ultra-Low-Noise, el NF-A9 FLX (Flexibilidad) puede ser ajustado para un flujo de aire superior o un silencio máximo.
|
Extensas opciones de cableado
El cable corto principal del ventilador, de 20 cm, minimiza la acumulación de cables en las aplicaciones típicas, mientras que el cable de extensión de 30 cm incluido proporciona un alcance mayor cuando sea necesario. Los dos cables están completamente enmallados.
|
6 años de garantía de fabricante
Los ventiladores de Noctua son conocidos por su impecable calidad y su larga vida útil. Como todos los ventiladores de Noctua, el NF-A9 dispone de una MTBF de más de 150.000 horas con una completa garantía de fabricante de 6 años.

NF-A9 FLX Opinión
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.

Resultado del análisis: "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-A9 FLX Opinión
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-A9 FLX Opinión
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.

NF-A9 FLX Opinión
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.

NF-A9 FLX Opinión
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?
- 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.

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.

Can I use Noctua fans in my system from Acer, Apple, Dell, HP, Lenovo or other major brands?
How big is the NH-D15S and how much clearance does it provide for RAM and mainboard heatsinks? Copy
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.
