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.
2000rpm industrialPPC version

2000rpm industrialPPC version

Thanks to its elevated 2000rpm top speed, the NF-A14 industrialPPC-2000 provides a significant performance boost over the 1500rpm retail version. Combined with the industrialPPC series' robust polyamide construction and advanced protection features, this makes the fan ideal for challenging industrial applications.
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.
Class-leading energy efficiency

Class-leading energy efficiency

While the standard NF-A14 is one of the most energy efficient 1500rpm 140mm fans on the market, the industrialPPC version's three-phase motor provides a further 10% reduction in power consumption when compared at 2000rpm.
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.
Certified IP52 water- and dust protection

Certified IP52 water- and dust protection

Thanks to a special varnish coating that covers the motor and PCB, the NF-A14 industrialPPC complies with the ingress protection rating IP52. This means that it is not only highly dust resistant but also withstands dripping water equivalent to 3mm rainfall per minute.
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.
6-year manufacturer’s warranty

NF-A14 industrialPPC-2000 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)

Como já foi dito as Noctua IndustrialPPC são ventoinhas para quem pretende o maior desempenho possível e que aguentem qualquer tipo de ambiente, são ventoinhas com uma construção fabulosa e com um alto desempenho. Nos nossos testes no Noctua NH-D15S as ventoinhas apresentaram bons resultados, sendo que quem pretender silencio estas ventoinha são imediatamente excluídas e com isto quero dizer que o nível de ruído pode-se tornar bastante incomodativo. A nível de acessórios poderiam incluir um adaptador para reduzir a voltagem e até mesmo acessórios para fixar as mesmas.
Test verdict: "No geral é um produto que recomendamos a quem pretende ter o maior desempenho possível e que não se importe com o nível de ruído. A qualidade de construção é o factor chave na escolha destes modelos." (João Teixeira, JotaReviews.pt)

NF-A14 industrialPPC-2000 Review

The efficiency test, in which we test what the airflow is at a set noise level of 30 dB(A), is in our opinion the most important, because we prefer to see coolers that are silent and cool well. The best ones are the Noctua NF-A14 industrialPPC-2000 140mm IP67 PWM and the Noiseblocker NB eLoop 140mm 1200 rpm PWM, which produce 32.7 cfm at 30 dB(A). The first one is relatively expensive, but aimed at industrial application and moreover waterproof.
Test verdict: "The most efficient and thus "best" 140mm fans are the Noctua NF-A14 industrialPPC-2000 140mm IP67 PWM and the Noiseblocker NB-eLoop 140mm 1200rpm PWM. Both deserve an Ultimate award." (Farzin Parham, Hardware.Info)

NF-A14 industrialPPC-2000 Review

De efficiëntietest, waarbij we testen wat de airflow is bij een vaste geluidsproductie van 30 dB(A), is wat ons betreft echter het belangrijkst, omdat wij graag koelers zien die stil zijn én goed koelen. De beste zijn de Noctua NF-A14 industrialPPC-2000 140mm IP67 PWM en Noiseblocker NB-eLoop 120mm 1200rpm PWM, die bij 30 dB(A) nog 32,7 cfm produceren. De eerste is relatief duur, maar gericht op industriële toepassingen en onder meer waterdicht.
Test verdict: "De meeste efficiënte en daarmee “beste” 140mm ventilators uit de test zijn de Noctua NF-A14 industrialPPC-2000 140mm IP67 PWM en Noiseblocker NB-eLoop 140mm 1200rpm PWM. Beide verdienen een Ultimate Award." (Koen Crijns, Hardware.Info)

NF-A14 industrialPPC-2000 Review

The Noctua Redux and IndustrialPPC ranges add a much needed customisation to their range. Of course, the Redux fans are of an older design, and the performance may suffer as a result. However, the greys of the Redux and the black of the IndustrialPPC range enables system builders to more thoroughly theme their build and thus the sacrifice in performance or price may be considered worth it. The IndustrialPPC range also adds a ruggedness that some systems will require – water and dust resistance will enable significantly longer lifetimes with a higher MTBF.
Test verdict: "The usual Noctua product quality is still to be found here, and these fans are well worth considering for your system. Though the IndustrialPPC (and, let’s face it, the standard Noctua product line) remain quite expensive for the functionality they provide, the Redux line brings excellent acoustics and performance to more accessible price points. And as for the IndustrialPPC fans, we get the feeling that many enthusiasts will happily look over the price point in the quest for the best." (John Morrison, SmallFormFactor.net)

NF-A14 industrialPPC-2000 Review

Jumping right into it and there is no denying the performance the industrialPPC range has to offer. Not only did they out-perform the fans I tested them against, they have a lot of other features that will allow them to perform better than your average fans. For one, the IP67 rating not only means they are water and dust proof, this also adds longevity to the fans as nothing will be getting in the motor and essentially slowing it down over time. Not only did they knock a good few degrees of my CPU temps during the test, they were also noticeably quiter than the fans they were tested against. When I say noticeably, I do in fact mean that, I could actually hear that they were a lot quieter than the other fans on test at the time.
Test verdict: "The industrialPPC fans offer great performance and design in a package designed for some serious cooling power, all in all a very worthy buy if you can make use of things like the IP67 rating." (Ben Enos, EnosTech.com)

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

Can I use Low-Noise Adaptors for industrialPPC fans?

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

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.

How can I check if my 4-pin fan header supports PWM?

Some mainboards feature 4-pin fan headers that actually don‘t use a PWM signal on Pin 4 to control the fan speed but rather reduce the voltage on Pin 2 (like a standard 3-pin fan header). As the fan speed at minimum voltage is usually higher than the speed at 20% PWM duty cycle, the fan can not reach as low minimum speeds under voltage control as under PWM control. Please refer to your mainboard manual to check whether or not your mainboard has 4-pin fan headers that control the fan speed by reducing voltage on Pin 2 rather than by changing the PWM duty cycle on Pin 4:

4 pin fan header types

Note that mainboard manufacturers use different terms to indicate that Pin 4 is not being used for PWM control (e.g. “+5V”, “VCC” or “NC”), but if one of these terms is used, you can be sure that the fan header does not support PWM. If Pin 4 is described as “Speed Control” or “PWM” or the like, you can be sure that the fan header supports PWM.

Unfortunately, the description of Pin 2 is not always a clear indication as some manufacturers use terms such as “Fan PWR” or “Power” for both types of fan headers. However, if Pin 2 is described as “Speed Control”, you can also be sure that the fan header does not support PWM based speed control. If Pin 2 is described as “+12V”, this is a clear indication that the fan header supports PWM.

Please also note that in some cases, the descriptions of the pin layouts in the mainboard manuals may not be correct and some models actually allow you to switch the fan headers from voltage control mode to PWM control mode in the BIOS even though the pin descriptions do not indicate PWM support. We thus recommend to look for these options in the BIOS before taking other measures. In case of doubt, please contact your mainboard manufacturer.


If your mainboard features other 4-pin fan headers that use PWM for speed control, you can run multiple fans from these headers using Y-split cables. Make sure not to exceed the specified maximum power draw of the fan headers (usually 10-12W) though.
