Conceived for industrial heavy duty applications that require enhanced cooling performance and advanced ingress protection, the NF-A14 industrialPPC (Protected Performance Cooling) is a ruggedised high-speed version of the award-winning retail model. Thanks to the outstanding aerodynamic efficiency of the NF-A14 design and the use of a novel three-phase motor, the industrialPPC version provides superior airflow and pressure capacity while keeping noise levels and power consumption moderate as against comparable high-speed fans. While its fibre-glass reinforced polyamide construction and certified water and dust protection make the NF-A14 industrialPPC suitable for operation in challenging environments, the renowned SSO2 bearing technology guarantees an MTBF of over 150.000hrs. Topped off with Noctua’s trusted reliability and 6 years manufacturer’s warranty, the NF-A14 industrialPPC is an ideal choice for highly demanding applications that require superior flow rates and ultimate dependability.

Main Features

  • 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 - 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.
  • 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 - 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 - 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 140øC 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 - 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 - 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 - 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 - 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 - 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 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 - 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 - 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 - 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 - 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.

These really do remind me of the good old days when travel was not restricted due to the bat virus. The peaceful sound of a jet engine that greets me whenever these have to work above 60% rpm bring back all of the holiday memories back... 5/5 for build quality and value 6/5 for the nostalgia they bring.

Ah, the sweet sound of jet engines starting up... Remind of the times when you could fly planes high above the land and seas before the pandemic. I give these 6/5 for invoking pleasant memories...

I've used these to replace some intake fans on my server rack, now I have pleasant sound of a wiresaw coming from it as opposed to the previous jet engine explosions. I'm happy with my purchase, if you are using this for a home pc= don't bother, use some other noctua fans which are designed for a home pc. These are robust, loud and can melt your fan headers if your motherboard has low quality 6w pin headers instead of the more common, decent 9w ones.

Top product - as always the case with Noctua fans. Audible above 1500 rpm so I keep it set for 45% max (via bios/sortware) and it still pump more air than my other regular Noctua fans.


December 2019

Used as a front and rear push/pull on my case as well as excellent build quality from Noctua, at 3000rpm can be quite loud but use fan control and they are perfect for getting rid of all that heat. power quality and longlife was my drive for these fans and I`m not dissapointed.


June 2019

Really impressive performance and very smooth and quiet for a high flow rate and high pressure which is required for my liquid cooled radiator. It is rather pricey but you definately get what you pay for with Noctua, I would not consider buying cheap fans again. I've ordered several things from CCL lately and I've not been disappointed. I'd much prefer to buy from CCL than Amazon that's for sure!
