Award-winning NF-A14 design

Award-winning NF-A14 design

Having received more than 100 awards and recommendations from the international press, Noctua's NF-A14 has become a proven premium choice for 140mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.
3000rpm industrialPPC version

3000rpm industrialPPC version

Running twice as fast as the 1500rpm retail version, the NF-A14 industrialPPC-3000 provides extreme airflow and pressure performance. Combined with the industrialPPC series' robust polyamide construction and advanced protection features, this makes the fan ideal for challenging industrial applications.
24V version

24V version

The industrialPPC 24V models use a dedicated wide input range version of Noctua's NE-FD2 three-phase PWM motor driver IC. Supporting operating voltages from 6 to 30V, these models are ideal for 24V-based industrial applications and voltage- or PWM-based speed control.
Lower speed and noise levels in 12V PC environments

Lower speed and noise levels in 12V PC environments

While the industrialPPC 24V model has been designed with 24V industrial applications in mind, it runs at a maximum speed of around 1800rpm in 12V PC environments and can be slowed down further via PWM, thus combining industrialPPC features and design with Noctua’s signature quietness.
Three-phase motor design

Three-phase motor design

While most axial fans use single-phase motors with 4 slots, Noctua's industrialPPC fans feature a three-phase design with 6 slots, which provides smoother transitions between the slots and thus allows for even higher running smoothness, further reduced vibrations and unprecedented energy efficiency.
Certified IP67 water- and dust protection

Certified IP67 water- and dust protection

The motor and PCB of the IP67 version are completely cast in a special, highly heat conductive resin that combines thoroughgoing protection and effective motor heat dissipation. Complying with the ingress protection rating IP67, this fan is not only fully dust tight but also completely waterproof up to 1m water depth.
Fibre-glass reinforced polyamide construction

Fibre-glass reinforced polyamide construction

Both the impeller and the frame of Noctua’s industrialPPC fans are made entirely from fibre-glass reinforced polyamide. This material can withstand temperatures up to 140°C and makes the fans even more robust and break-proof than Noctua’s standard fibre-glass reinforced PBT fans.
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 industrialPPC 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 industrialPPC 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 industrialPPC uses Noctua's custom-designed NE-FD2 PWM IC for three-phase motors. The NE-FD2 integrates Noctua's proprietary Smooth Commutation Drive (SCD) technology, which suppresses PWM switching noises and thus makes the fan quieter at lower speeds.
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 industrialPPC features an MTTF rating of more than 150.000 hours and comes with a full 6-year manufacturer’s warranty.

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

These are some serious overbuilt products. At first glance, the minimalist design might fool you but as soon you put them to work these are outstanding pieces of tech. With so many technologies under the hood there is no denying the fact that when companies aim and persevere to offer maximum quality, their products will impose a lot of respect. Even though these IndustrialPPC series fan are not built per say for desktop application, their versatility nature can cover those scenarios as well, thus a testament of their broad range of application. In an age of fast consumerism, products like these are rare. We are really impressed with these IndustrialPPC fans and thus they will take our maximum rating today because Noctua covered basically every aspect of how a versatile and perfect fan should be.
Test verdict: "Noctua outdid themselves yet again!" (Alex Nistor, Glob3trotters.com)

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

Su „Kelvin S36“ komplektuojamus „Fractal Desing“ HP ventiliatorius neturime perdaug už ką girti (skirtingai nei AIO sistemų mūšyje), nes lėčiau besisukantys „NF-F12 IndustrialPPC-24V-3000 iP67“ ventiliatoriai ne tik kad sugeba būti tylesniais, bet ir rodo to paties lygio ar net šiek tiek geresnį efektyvumą. Skirtumas galėtų būti akivaizdesnis, jeigu varinis radiatorius būtų tankesnis. Nenuostabu, kodėl „Fractal Design“ atsisakė šių HP ventiliatorių gan greitai pakeisdama juos į kitus. „NF-A14 IndustrialPPC-24V-3000 iP67“ jau nedominuoja abiejuose frontuose, nes standartiniai „Corsair H110i GTX“ sistemos ventiliatoriai pasižymi puikiu maksimaliu efektyvumu. Tiesa, kurtinančio triukšmo sąskaita. „Noctua“ ventiliatoriai negali prilygti efektyvumu (mažiausias deficitas 3 °C), tačiau net ir intensyvesnius apsisukimus turintys industriniai NF-A14 modeliai sugeba tiek sumažinti triukšmą, kad galima drąsiai taikyti dienos ir nakties palyginimą. Tai leidžia manyti, kad industriniai NF-A14 modeliai yra tikrai neprastai subalansuoti, greičiausiai visgi su šiek tiek didesniu potraukiu į tylą, o ne mažiausios temperatūros gainiojimąsi. Išgirdus šių ventiliatorių darbą kažkam „Noctua“ vardas gali prasilenkti su žodžiu tyla (47 dBA yra vis dar pakankamai triukšminga), tačiau kol kas ant 280 mm radiatoriaus dar nesutikome mažesnius skaičius garantuojančių gamyklinių ventiliatorių. „NZXT Kraken X61“ su 49 dBA ne išimtis. Reziumuojant paskutiniu sakiniu, galutinis pasitenkinimo lygis „IndustrialPPC-24V“ ventiliatoriais priklausys nuo to, ko iš jų tikimąsi ir kokius ventiliatorius jie keis.
Test verdict: "Tikslas pasiektas. Testais paremtas „IndustrialPPC-24V“ ventiliatorių sugretinimas su AIO sistemų turimais gamykliniais ventiliatoriais atskleidžia visų stipriąsias ir silpnąsias puses." (Matas Orentas, Technews.lt)

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

Σήμερα θα εξετάσουμε, για ακόμη μία φορά, την πρόταση που έχει να προσφέρει η Noctua στον τομέα των ανεμιστήρων, φέρνοντάς μία ριζική αλλαγή (πρωτίστως για αυτήν). Για ποιο λόγο, ονομάζουμε ριζική την αλλαγή θα καταλάβετε αμέσως. Σχετικοί και μη, έχετε σίγουρα ακούσει την αδιαμφισβήτητη ποιότητα προϊόντων της Αυστριακής εταιρίας, στον τομέα της ψύξης, με ειδίκευση στους CPU Coolers και fans. Σίγουρα την ποιότητα δεν μπορεί να την αμφισβητήσει κανείς, κάτι το οποίο δεν ισχύει και τόσο πολύ για την εμφάνιση των προϊόντων (εάν και εδώ έχουμε να κάνουμε με τελείως υποκειμενικά γούστα, αλλά η προηγούμενη άποψη προκύπτει από αντικειμενικές γνώμες και reviews).
Test verdict: "Εν κατακλείδι, δηλώνω γοητευμένος τόσο με την σειρά IndustrialPPC, η οποία μπορεί να σταθεί και να ανταμείψει και τους πιο απαιτητικούς καθώς και με τον πανέξυπνο τρόπο που η Noctua έδωσε την επιλογή του customization αυτών, μέσω της Chromax σειρά, Μία σειρά, η οποία θα ήθελα να ανανεωθεί με καινούργιους χρωματισμούς, όπως για παράδειγμα πορτοκαλί, μοβ κλπ."

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

Through the 12V tests, which I was able to perform both of the fans provided stable and very reliable airflow levels, while maintain middle to low noise levels which makes them a good choice for regular or enthusiastic customers who demand high airflow and high static pressure levels from the cooling fans to keep their machines working cool, stable and quiet for a long time.
Test verdict: "[A] really good choice to be used as CPU cooler fans installed on a heat sink or water cooling radiator compatible with 140mm fans to keep every modern processor running cool and stable at default or overclocked frequencies." (Dobrin Krastev, DVTests.com)

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

«Примочки», под которыми конечно подразумеваются цветные силиконовые гвозди и угловые подкладки, - они мне понравились. Называются, напомню, Anti-Vibration Pads (NA-SAVP1) и Anti-Vibration Mounts (NA-SAVP2). Недорогие, в упаковке их много, и реально снижают шум. Поменять всю систему охлаждения в корпусе – это влетит в «копеечку», а силиконовые гвозди могут немного все сделать тише, да и на будущее останутся. Гарантия 6 лет=) Серия IndustrialPPC – решения скорее специализированные, но 12 В модели к покупке можно смело рекомендовать. И я не знаю насколько на заводе будет полезна защита по стандарту IP67, но за возможность помыть вентилятор под краном просто спасибо Noctua. Redux – универсальность и доступность. Noctua, как известно, делать хорошие вещи, но дорогие. Благодаря изменению комплекта, а как следствие и конечной цены, но сохранению подхода к самому изделию, вентиляторы серии Redux в некоторой степени стали «ближе к народу».
Test verdict: "В этот раз не будет привычных плюсы/минусы. И силиконовые крепления Chromax, и вентиляторы серий IndustrialPPC и Redux – все это к покупке можно рекомендовать. К тому-же, на абсолютно всю продукцию компании 6 лет гарантии, что как-бы намекает на качество." (Oleg Ubeiko, OCClub.ru)

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

La tensione di alimentazione a 24 volts delle IndustrialPPC provate potrebbe sembrare un limite alla loro diffusione sul mercato, ma secondo noi può invece essere un punto di forza. Se utilizzate a 12 volts si comportano infatti come le ventole della serie Standard con vantaggi dovuti al motore ulteriormente migliorato, ma nel caso che le esigenze di raffreddamento cambino nel tempo è sufficiente dotarsi di una fonte di alimentazione differente per avere qualcosa con prestazioni assolutamente fuori dal comune. In quest’ottica ci sentiamo quindi di consigliare le versioni da 3000 rpm, utilizzate a 12 volts infatti garantiscono un range di funzionamento che permette il loro utilizzo in quasi tutti i campi. Ottime per areazione case e da applicare su dissipatori ad aria possono spingersi fino al raffreddamento di radiatori a basso indice FPI.
Test verdict: "In conclusione ci sentiamo di consigliare queste ventole a tutti gli appassionati del marchio Noctua che puntano ad avere dei prodotti unici sul mercato, in grado di coprire tutti i campi di utilizzo grazie alle prestazioni superiori alla media coniugate alla classica qualità che da sempre contraddistingue il produttore austriaco."

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

Eccoci arrivati alle conclusioni, ovviamente come tradizione siamo rimasti piuttosto colpiti dalle nuove fan 24v di Noctua. Noctua si rivela sempre una garanzia quando si tratta i ventole o sistemi di dissipazione complessi, ma ciò che contraddistingue l’azienda è la continua ricerca verso la perfezione, su prodotti orientati a tutte le fasce. Sia che acquistate prodotti low o performance/enthusiast, la cura dei dettagli sarà sempre maniacale, ed ogni prodotto è sempre al top. Le nuove IPPC sono fenomenali e fin troppo potenti per i sistemi medio/alti, la pressione d’aria è notevole, il rumore non eccessivo e le ventole non vanno mai a regime massimo in quanto superfluo. I dispositivi Chromax consentono di scegliere tutte le personalizzazioni ed i colori a proprio piacere.
Test verdict: "Chiaramente sono un acquisto consigliato, ed aggiungerei praticamente obbligato, se davvero si vuol tenere al fresco il proprio PC." (Matteo Carrara, PC-Gaming.it)

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

Noctua ha trabajado muy bien y ha realizado correctamente su trabajo con esta nueva gama, más destinada a equipos tipo servidores que estén encendidos mucho tiempo, dado a que posee un buen caudal de aire y una larga duración. También debido a sus revoluciones, ofrecen más ruido que su anterior gama Redux, un dato quizás importante a la hora de adquirir uno de estos IndustrialPPC. Noctua también ha mejorado en el aspecto de la personalización, pues ha mejorado, permitiendo añadir colores personalizados a nuestros ventiladores IndustrialPPC gracias a la gama de accesorios Chromax, la cual nos ha encantado.
Test verdict: "Noctua ha lanzado esta gama de ventiladores muy profesionales con un buen caudal de aire y refrigeración. Además gracias al soporte de su nueva gama Chromax, podemos personalizarlo para que se adapte como nos gusta a nuestro equipo." (Adrián José Pérez Toré, Top10Games.es)

Entrando más en detalle, podemos ver como el propio diseño de los ventiladores es muy distinto al que Noctua nos tiene acostumbrados, siendo estos en color negro y las gomas anti vibración en color granate oscuro, como ya vimos en la review de la serie IndustrialPPC de 12V. Construidos en poliamida reforzada con fibra de vidrio y motor trifásico con el sistema de rodamientos SSO2, los ventiladores IndustrialPPC nos ofrecen una gran calidad de materiales muy robustos, y un tiempo de vida medio superior a las 150.000 horas. Todos ellos cuentan con certificado de protección IP67 que los hacen perfectos para su uso industrial, de ahí su nombre, debido a que aseguran su protección total ante el polvo y permiten ser sumergidos en agua hasta un máximo de un metro.
Test verdict: "La serie IndustrialPPC 24V está enfocada para su uso industrial, por ello, su nombre, y esta versión de 24V con más motivo, a diferencia de los modelos de 12V. Por ende, se pueden considerar unos ventiladores todoterrenos, capaces de funcionar tanto a 12V como 24V de tensión." (Asis Ferrer, Formula Hardware)

NF-A14 industrialPPC-24V-3000 IP67 PWM Review

The larger NF-A14 gives a great improvement over the stock fan on test and a couple of these would be excellent in a homeserver for example, or on a water-cooled systems radiators, the would move a lot of hot air away from the cooling fins. The NF-F12 would be an excellent upgrade for a normal desktop system too, they would comfortably cool servers and water-cooled rigs as well, but have a little better sound performance, so your tolerance is not tested by noisy fans.
Test verdict: The Noctua industrialPPC fans that we have tested in this review have impressed us. It’s probably a little unfair to pitch them against the humble stock chassis fan, but most people will have them right now in their system and any upgrade is always a welcome one. The Noctua industrialPPC fans are not aimed at the average desktop end-user, but they can be applied with success.

Information Sheet (PDF)

Can industrialPPC fans be used with fan controllers and resistor cables (Low-Noise Adaptors)?

Noctua recommends not to use industrialPPC fans with common PC fan controllers, resistor cables (Low-Noise Adaptors) or other devices such as potentiometers that work by applying (variable) resistance rather than actually generating different voltages such as a laboratory power supply does. Due to the higher internal resistance of the industrialPPC fans’ three phase motor, applying additional resistance will cause the fans not to start (e.g. with Low-Noise Adaptors) or to have high starting speeds (e.g. with most common PC fan controllers). Please note that the industrialPPC fans feature starting voltages between 5.5V and 6V and can be run at these voltages on devices such as laboratory power supplies or mainboard fan controllers which actually generate lower voltages rather than applying resistance. Noctua thus recommends to use either PWM or voltage based mainboard fan control or laboratory/industrial power supplies for controlling the speed of industrialPPC fans.

4-pin PWM 3-pin
Mainboard fan control PWM based yes no
Mainboard fan control voltage based yes yes
Resistor cables (Low-Noise Adaptors) no no
Common PC fan controllers no
(high starting speed)
no
(high starting speed)
Laboratory/industrial power supplies yes yes

My fan doesn’t spin when I start up the PC - is it faulty?

If you've connected the fan directly (or using the supplied Low-Noise or Ultra-Low-Noise-Adaptors) to your mainboard, it's possible that the mainboard's automatic fan controller doesn't provide the required starting voltage due to the low CPU temperature. Please verify whether the fan starts spinning at higher CPU temperatures, remove any Low-Noise or Ultra-Low-Noise Adaptors, deactivate your mainboard's automatic fan controller in the BIOS or connect the fan directly to the power supply using the supplied 3:4-pin adaptor.

Can I use Low-Noise Adaptors for industrialPPC fans?

No, Low-Noise Adaptors are not compatible with Noctua’s industrialPPC series.

What pin configuration do Noctua 24V fans use?

The pin configuration of Noctua 24V fans is identical to 12V fans:

24v pin configuration

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.
