Succeeding the award-winning NF-P14

Succeeding the award-winning NF-P14

Noctua's NF-P14 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 140mm fan. Thanks to its thoroughgoing aerodynamic optimisations, the NF-A14 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.
Square 140mm frame

Square 140mm frame

The NF-A14's square 140mm frame with 140mm mounting holes (124.5mm spacing) makes it a premium grade replacement for common 140mm case fans and perfect for use on 140mm water cooling radiators, where its square shape will ensure full coverage and best pressure performance.
Flow Acceleration Channels

Flow Acceleration Channels

The NF-A14 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.
AAO Frame

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

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

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

Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
SSO2 Bearing

SSO2 Bearing

The NF-A14 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.
Metal bearing shell

Metal bearing shell

In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-A14 sports a CNC milled bearing shell made entirely from brass.
Custom-designed PWM IC with SCD

Custom-designed PWM IC with SCD

Supporting fully automatic PWM speed control, the NF-A14 PWM uses Noctua's novel, custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.
Low-Noise Adaptor

Low-Noise Adaptor

The NF-A14 PWM is supplied with a (L.N.A.) that reduces the maximum fan speed from 1500 to 1200rpm. The L.N.A. can be used either to run the fan at a fixed speed of 1200rpm or to cap the maximum speed when using automatic PWM control.
Extensive cabling options

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 and a 4-pin y-cable allows the connection of a second NF-A14 PWM fan to the same PWM fan header for automatic control.
6-year manufacturer’s warranty

6-year manufacturer’s warranty

Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A14 features an MTTF of more than 150.000 hours rating and comes with a full 6-year manufacturer's warranty.

NF-A14 PWM Review

Na prvi pogled ne vidimo ništa specijalno, ali ako iz dobijenih temperatura jezgra izračunamo proseke, stvari će biti jasnije. Kuler sa ventilatorom koji je radio na 1200 obrtaja je ostvario maksimalnu temperaturu od 83,5°C. Kada je hladnjak bio opremljen sa bržim ventilatorom na 1500 obrtaja, maksimalna zabeležena temperatura je bila 80,5°C. Dakle, cela tri stepena, što je primetna razlika u oku entuzijasta. Sad Vam je valjda jasnije zašto je NH-D14 izgubio od NH-14S. Zato što tih 'par obrtaja viška' znače puno za konačan rezultat.
Test verdict: "PWM verzija od ovog 140mm ventilatora će naravno dobiti tradicionalnu 'PCAXE Diamond' nagradu. Noctua-u ne vredi da hvalimo išta posebno, oni koji razumeju njihovu ideologiju, namenu i kvalitet, oni će prihvatiti ovaj proizvod kao i svaki drugi od Noctua-e." (Atila Gobor, PCAXE.com)

NF-A14 PWM Review

Il test effettuato non fa altro che confermare le già ottime impressioni dateci sin dall'apertura della scatola: questa ventola è un prodotto premium, e si vede. Noctua è stata in grado di realizzare una ventola da 140 millimetri, la NF-A14 PWM, che oltre a muovere una notevole quantità d'aria, essendo così utilizzabile su di un heatsink ad aria od un radiatore, è anche eccezionalmente silenziosa, perfetta quindi per l'applicazione come case fan.
Test verdict: "La ventola Noctua NF-A14 PWM si è dimostrata, come da aspettative, di altissimo livello. A cominciare dal bundle, completo e ben realizzato, comprensivo anche di antivibrazionali che sono una vera e propria manna dal cielo contro i fastidi dovuti dalle vibrazioni; nonostante la ventola abbia il controllo PWM automatico per la velocità, Noctua ha pensato bene di inserire nella confezione anche un adattatore L.N.A. per tutti coloro i quali non vogliono o non possono collegare il prodotto ad un attacco 4-pin o ad un fan controller. La ventola in sé, inoltre, è molto solida e priva di qualsivoglia scricchiolio, ma anzi, grazie alla struttura che vede la presenza di parti in gomma, è anche nei limiti del possibile a prova d'urto."

NF-A14 PWM 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.
Test verdict: "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-A14 PWM Review

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.
Test verdict: "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-A14 PWM Review

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.
Test verdict: "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-A14 PWM Review

Im Einsatz zeigen die neuen Noctua-Lüfter dann sofort und nahezu uneingeschränkt ihre Stärken. Schon nach wenigen Sekunden ist klar, das sich die Geräuschemissionen des schon vom Werk aus recht leisen Nanoxia Deep Silence 1, noch weiter senken lassen. Als wäre dies nicht genug, lassen sich die beiden NF-S12A, wie auch der NF-A14 in ihrer Arbeitsgeschwindigkeit leicht nach unten korrigieren, ohne dabei an Performance, in diesem Fall Kühlleistung bzw. Luftdurchsatz, zu verlieren. Ein klares Zeichen, das Noctua mit der dritten Generation seiner NF-Lüfter, doch noch einen, wenn auch nur kleinen Schritt nach vorn machen konnte und im Premium-Segment nicht nur bei der Ausstattung, sondern auch der Leistung weiterhin Maßstäbe setzen kann. Ebenfalls lobenswert ist das breite Drehzahlband, welches von den NF-Lüftern abgedeckt wird. Die Spanne reicht hier, fein gestaffelt, von einer Anlaufgeschwindigkeit knapp unterhalb von 600 U/min. (ca. 50 %), bis hin zu leistungsorientierten 1200 U/min. (100 %).
Test verdict: "Noctua beweist mit der aktuellen Generation der NF-Lüfter sein geballtes Know-How im Bereich der Luftkühlung und bietet für nahezu jeden Einsatzzweck das passende Produkt in seinem Sortiment. Ganz klar haben die Österreicher es nicht geschafft, das Rad oder in diesem Fall den Gehäuse-Lüfter komplett neu zu erfinden, können aber mit Stolz behaupten, das mit Abstand Beste Gesamt-Konzept für performanceorientierte Silent-Systeme zu bieten. Die Fülle an wohl durchdachten Detaillösungen machen die Noctua NF-Lüfter zu einem ganz besonderen Gut und verhelfen diesen zu einer Art Ausnahmestatus. Materialwahl, Verarbeitung und alles in Summe, die Gesamtqualität, sind überragend und garantieren somit in ihrer Gesamtheit eine besonders lange Lebensdauer, was Noctua mit einer gewährten Garantiezeit von 6 Jahren unterstreicht."

Can I run 4-pin PWM fans on 3-pin fan headers?

PWM fans come with a 4-pin connectors for fully automatic speed control via your mainboard’s 4-pin PWM fan headers. Please note that 4-pin fans can also be connected to your mainboard’s 3-pin fan headers though. When connected to 3-pin fan headers, the fan will run at full speed (unless the mainboard supports voltage based speed control).

Which Noctua 140mm fans are optimised for airflow, which are optimised for static pressure?

Noctua only distinguishes between airflow optimised and pressure optimised fans in its 120mm range (see this page for details). For 140mm fans, there is no such distinction: Both the NF-A14 and the NF-P14 redux models are true all-rounders that provide outstanding levels of airflow and static pressure. Either of them works excellent both for case cooling and for use on radiators and heatsinks.

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!

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.
