Superando al tan premiado NF-P14

Superando al tan premiado NF-P14

El ventilador NF-P14 se ha convertido en la opción por excelencia entre los entusiastas de PC que buscan ventiladores silenciosos de 140 mm de alta calidad. Gracias a su profunda optimización aerodinámica, el NF-A15/14 proporciona una presión estática más alta y aún mejor índice de flujo de aire por ruido que el de su aclamado predecesor.
Marco redondo de 140 mm con un ancho de 150 mm

Marco redondo de 140 mm con un ancho de 150 mm

El NF-A15 está hecho a medida para su uso con modernos disipadores de CPU de alta gama: Al mismo tiempo que su ancho de 150 mm coincide con la de los disipadores de alta gama, su altura de 140 mm hace que no sobrepase la parte superior garantizando así mejor compatibilidad con cajas. Además, los agujeros de montaje estándares de 120 mm del NF-A15 (espaciamiento de 105 mm) resultan en una mejora en rendimiento ideal para ventiladores de caja o de procesador de 120mm.
Flow Acceleration Channels (canales de circulación acelerada)

Flow Acceleration Channels (canales de circulación acelerada)

El rotor del NF-A15 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.
Diseño de entrada paso a paso

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.
Rodamientos SSO2

Rodamientos SSO2

El NF-A15 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.
Cojinete de metal

Cojinete de metal

Con el fin de garantizar el máximo grado de precisión posible en su fabricación, una tolerancia mínima y una excelente estabilidad a largo plazo, el NF-A15 usa un cojinete CNC fresado hecho totalmente de latón.
PWM IC de diseño propio con SCD (Unidad de Conmutación Suave)

PWM IC de diseño propio con SCD (Unidad de Conmutación Suave)

Con soporte total para un control de velocidad PWM automático, el NF-A15 PWM usa el nuevo NE-FD1 PWM IC de diseño propio de Noctua que se integra con la tecnología Smooth Commutation Drive (SCD, Unidad de Conmutación Suave). Proporcionando impulsos de par más suaves, el SCD disminuye los ruidos de cambios del PWM y hace que el ventilador funcione de forma más silenciosa a velocidades bajas.
Low-Noise Adaptor (Adaptador de Reducción de Ruido)

Low-Noise Adaptor (Adaptador de Reducción de Ruido)

El NF-A15 PWM viene con un Low-Noise Adaptor L.N.A. (adaptador de reducción del ruido) que reduce la velocidad máxima del ventilador de 1200 a 900 rpm. El L.N.A. se puede usar tanto para usar el ventilador a una velocidad fija de 900 rpm como para fijar una velocidad máxima al usar el control de PWM automático.
Opciones de Cableado Extensible

Opciones de Cableado Extensible

El corto cable principal de 20cm del ventilador minimiza el lío de cables en situaciones típicas mientras que el cable de extensión de 30cm que se suministra permite un alcance extra cuando resulta necesario. Ambos cables están totalmente forrados.
Consumo ultra bajo

Consumo ultra bajo

Aunque el rendimiento ha sido mejorado, el NF-A15 consume solo 0,96W, lo que resulta en una reducción del 20% comparando con su predecesor. Esto no solo lo hace inocuo para el medio ambiente sino que también ayuda a ahorrar en la facturar de la electricidad.

NF-A15 PWM Opinión

As you can see the NF-A15 PWM fan definitely offered up an advantage over the 140mm fans at equivalent speeds. This advantage on our system is around 2 degrees. At 900 RPM the NF-A15 PWM fan gives about 1 degree better performance than the NF-A14 FLX. [...] The key things to draw from this graph are that the NF-A15 PWM fan does offer better performance than a 140mm at equivalent speeds. It is also quite clear that the Noctua fans excel in offering high airflow/performance at low RPMs, very useful for people who want quiet but cool systems. [...] Since we used a new acoustic testing methodology for these fans the results are not comparable with any other fan reviews we have done – sorry about that. But the results are interesting because they show that actually the Noctua fans are neck and neck with the provided Thermalright 140mm fan that comes with the CPU cooler we tested on. However, as we saw on the previous page, you get better cooling performance at the same level of acoustic output which can only be a good thing.
Resultado del análisis: "The end result of all this is more cooling performance than a 120mm fan can offer simply because the bigger a fan is, the more air it can shift. That said, if anyone is looking for the ultimate push-pull CPU heatsink configuration then I cannot recommend these fans highly enough. I would like to award the NF-A15 PWM fan the eTeknix Extreme Performance Award because as far as fans go, it offers exactly that but still gives you silence, quality, reliability and style."

NF-A15 PWM 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.
Resultado del análisis: "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.

NF-A15 PWM Opinión

Tras probar las serie NF-A de 140mm podemos decir que estamos ante cuatro grandes ventiladores, en general silenciosos y con un buen caudal aire. De la serie NF-A14 tenemos el modelo FLX que es silencioso y mueve un buen caudal de aire. El modelo ULN es el más silencioso de los analizados, es inaudible aunque su caudal no es excesivamente alto pero suficiente para refrigerar nuestra torre. El modelo PWM es silencioso eso si, a máximas revoluciones empieza a sonar algo más, moviendo un gran caudal de aire. De la serie NF-A15 el modelo PWM es el que más caudal mueve de los cuatro modelos analizados, a máximas rpm ya suena algo pero es normal debido al gran flujo de aire que genera. Concluimos que son ventiladores muy similares, cuyas diferencias son la velocidad de rotación. El modelo ULN está especialmente diseñado como ventilador auxiliar por su baja sonoridad. El modelo NF-A14 FLX destaca por ser silencioso y tener un buen rendimiento, pudiendo regularle las rpm mediante los adaptadores que incluye. El modelo NF-A14 PWM destaca por ofrecer un gran rendimiento regulando las rpm forma automática. Y el modelo NF-A15 PWN que tiene la particularidad de que dispone agujeros de montaje de 120mm, destacando su gran caudal de aire y sonoridad.
Resultado del análisis: "No hace falta decir nada más, que hemos analizados unos grandes ventiladores muy versátiles, silenciosos y con un gran rendimiento, así que no podemos dejar de recomendarlos." (Jose Maria Martinez Perdigones, ActualidadHardware.com)

NF-A15 PWM Opinión

Comme d'habitude chez Noctua les nuisances sonores sont très basses, ils sont tous inaudibles à 5v et se font entendre à 12v, à part pour le ULN qui lui reste quasiment inaudible même à fond! Les ventilateurs produisent tous un son grave (comme tous ceux de la marque) qui n'est pas gênant et les moteurs sont dépourvus de bruits parasites, un très bon point.
Resultado del análisis: "Nous voici arrivé au terme de ce test, que dire de ces Noctua NF-A14 ? On voit bien qu'ils sont de la même famille que les NF-S12A et continuent dans l'excellence, que ce soit au niveau des performances que dans le bundle en passant par un SAV au top et 6 ans de garantie. Vous ne pouvez pas vous tromper en optant pour un de ces ventilateurs" (Christian Marchini, Conseil Config)

NF-A15 PWM Opinión

Noctua has devoted itself to quiet cooling. In that they have succeeded well. One measure of their insistence on quietness was their not bringing PWM products to market until they were ready to do it the Noctua way. “Fans” of Noctua’s fans long wrote about how they wanted PWM versions, yet there were no PWM fans from Noctua. But it turned out that Noctua was not ignoring PWM; their engineers were working on developing a silent PWM control. The clicking seen in other PWM fans – even quiet clicking – is completely absent in Noctua PWM fans. This started with their NF-F12’s, and has now extended to their A series. All are clickless. As well as can be measured in a non-professional setup, Noctua’s airflow specifications are accurate. You can listen to a fan and hear if it is quiet or not, and whether it makes unpleasant noises (Noctua fans are free of unpleasant noises). But airflow is another matter. Airflow takes special instruments to measure. It is comforting to know Noctua’s specifications on this are accurate; so you can use those specifications in your buying decisions. The various Low Noise Adapters and Ultra Low Noise Adapters are different for each of the fans. Clearly, they are tailored to achieve particular results. This may or may not be unique to Noctua fans. Interestingly, Noctua says nothing about it. The Noctua accessories are of good quality, and appear likely to last in extended usage. They are all handsomely sleeved as well. The fan frames are sturdy, and the corner cushions do not extend into the screw holes. That means the fans can be securely fastened with or without the cushions.
Resultado del análisis: "Overall, the Noctua A series is a fine set of fans. Careful attention to airflow and acoustics, along with the best PWM circuits in existence, make these superb fans." (Ed Hume, Vortez.net)

NF-A15 PWM Opinión

Keep in mind that while the test results aren't overwhelmingly spectacular, consumers are offered more options depending on what they're looking for. The Noctua NF-P14 was a "convertible" fan. It had 120mm hole spacings with 140mm extensions with a round frame, so it could fit 120mm or 140mm mounts However, like a real convertible with the top down, it's a bit louder. Round framed fans in general perform much better on air cooling radiators, but square framed fans in general perform better on watercooling radiators. Thus, you now have the option to choose between a variety of 140mm (and 150mm) fans from Noctua. Whether you're looking for the most optimal silent solution with the NF-A14 ULN, or a quieter replacement to the NF-P14 with the NF-A14 FLX that still does a great job with the U.L.N.A. adapter. The NF-P14 is still a solid performer and the NF-A15 PWM is a great replacement for 120mm fans where size isn't a factor. Decisions, decisions!
Resultado del análisis: "One of my favorite things about Noctua is how quiet its fans are without sacrificing thermal performance. Noctua pushes the boundaries of continually making improvements in all aspects of its products, and the latest from Noctua doesn't disappoint. Comparing these fans to their predecessor, the Noctua NF-P14, it's easy to notice the differences in design, and I could definitely hear less vortex noise!" (Ebon Kim, Overclockers Club)

NF-A15 PWM Opinión

Noctua's NF A-15 PWW, A-14 FLX, and the A14 ULN are a welcome addition to their lineup of cooling products. The NF-A15 PWM and the NF-A14 FLX run at 1200rpm when not equipped with the low noise adapters. This of course improves their overall performance at the cost of increased noise output from the fans. I am not saying they generate a lot of noise - as a matter of fact even at their maximum rotational speeds the fans are are extremely quiet, almost to the point that I continued to check just to make sure they actually were in operation. The NF-A14 ULN without a doubt generates the least amount of noise with or without the low noise adapter. [...] Noctua's NF-A15 PWM, NF-A14 FLX, and the NF-A14 ULN are priced around $24.00 each; a reasonable price considering the quality and performance of the fans (not to mention a 6 year warranty). In my book, that's a lot of bang for the buck.
Resultado del análisis: "Noctua's NF A15 PWM, A-14 FLX, and the A-14 ULN did an excellent job of keeping our testbed cool given the fact they are not high RPM fans. [...] [T]hese fans would make a great addition to either an HTPC or gaming PC for those who like quiet." (Roger Cantwell, Neoseeker.com)

NF-A15 PWM Opinión

Results were more mixed with the NF-A15 PWM, but that is due to the environment in which it is used rather than the fan itself. The NF-A15 PWM had excellent airflow, and did exactly what it was portrayed as being capable of. It did seem slightly louder (or perhaps just a more noticeable tone) than the NF-A14 FLX, but it was still a very quiet fan. On the more open finned Mugen 3, the NF-A15 had an nice performance increase over the stock fan, while dropping noise levels noticeably. On the more densely finned and differently shaped TC12DX, the NF-A15 did very well, but did not deliver as noticeable a performance difference. The degree of the gains from the NF-A15 are going to vary from cooler to cooler, but in almost any possible case, you can be assured that there will be at least some gain. Noctua has again put out a series of absolutely top notch fans with the NF-A 140mm varieties. The versatility of the offerings should offer up something for the needs of just about any situation, ranging from extreme cooling to extreme silence. As always, Noctua’s build quality is second to none with performance to match.
Resultado del análisis: "The Noctua name has become synonymous with quiet cooling and extreme performance. Many of their products are rightfully legendary in enthusiast circles, and deservedly so. Over the years, Noctua has set a very high standard for themselves to live up to, and the NF-A Series fans do not disappoint in any way. The three configurations are very well thought out, and add a great deal of versatility to the line." (George Cella, HiTechLegion.com)

NF-A15 PWM Opinión

Questa nuova serie, che verrà analizzata in modo superficiale in questo capitolo, rappresenta la volontà di Noctua di potenziare e consolidare la propria situazione nel panorama delle ventole aventi un diametro molto elevato, infatti a seguito dell’immissione in commercio di questi modelli si è raggiunto il completamento dell’offerta per ogni settore. La serie ULN e FLX da 140mm si caratterizza per il nuovo telaio AAO introdotto con l’eccellente ventola da 120mm NF-F12 Focused Flow, recensita da noi tempo fa (Qui), e per il cambiamento del formato da circolare a quadrato, oltre a tutta la nuova serie di migliorie tecniche e strutturali che sono già state menzionate nel capitolo precedente. L’intera serie “A” infatti presenta quasi sempre le medesime caratteristiche tecniche, indipendentemente da modello e dal diametro, per cui la qualità complessiva è sempre molto elevata.
Resultado del análisis: "Oltre a questo troviamo le Noctua A15 e A14, che occupano posizioni basse, ma che però presentano una rumorosità davvero irrisoria se rapportata alle altre, e quindi un comfort acustico invidiabile. Il modello A14 FLX, sebbene occupi l’ultima posizione, troviamo che sia il migliore di tutti per quanto riguarda il rapporto Temperature / dBA" (Matteo Trinca, XtremeHardware.it)

NF-A15 PWM Opinión

So in short, what can I say… The NF-A15 and NF-A14 cooling fans are proper Noctua quality with added new innovations. With every new design they unveil, Noctua brings out great airflow with minimal noise and are extremely reliable (I still use 5 year old Noctua fans). They are a bit more expensive than typical case fans but are worth every penny.
Resultado del análisis: "Would I buy these if I needed more? In a heartbeat. They are by far the best fans I ever had in my hands, and they have a six-year warranty to boot! I even replaced some older Noctua fans I still had. Don’t worry the older fans now spin in my friend’s case who needed some extra fans." (Daniel Pielage, OCmodshop.com)

Can use the NF-A15 fan on my Noctua CPU cooler?

The NF-A15 is fully compatible with the NH-U12P, NH-C12P and NH-C12P SE14. On the NH-D14 and NH-C14, the NF-A15 fan can only be installed using optional fan clips. For this, please contact our customer service.

Does the NF-A15 PWM that comes with Noctua coolers run at a different speed (1500rpm) than the retail model (1200rpm)?

Yes, the NF-A15 PWM bundled with our heatsinks is specified to run at 1500rpm (see cooler specifications for details) and the retail model is specified to run at 1200rpm (see fan specifications for details). The 1200rpm retail model is ideal for setting up push/pull configurations in combination with the coolers’ 1500rpm stock fan because the combination of the 1500 and 1200rpm models provides a better balance of performance and noise than the combination of two 1500rpm versions. On dual-tower coolers such as the NH-D15S, we recommend to run the 1500rpm version in the center and the 1200rpm version on the front. On single-tower coolers such as the NH-U14S, we recommend to run the 1500rpm version on the front and the 1200rpm version on the back of the cooler. The NA-YC1 y-cable supplied with the retail fan can be used in order to control both fans via one PWM fan header. In this case, both fans will scale individually according to the PWM duty cycle supplied by the motherboard, e.g. they will run at ~1500/1200 respectively at 100% duty cycle, ~750/600rpm at 50% duty cycle, etc. Both at 100% and lower speeds, the speed difference between the fans reduces resonance phenomena and thus helps to achieve the best balance of performance and noise.
