> 3 dayIm using these to cool a EK-420CE rad. At 200rpms theyre whisper quiet, and at full 2000rpms theyre loud, but thats expected at full tilt. Still quieter than anything Ive ran at 2K rpms. I did have 1 fan die on the 1st day of use, so I guess well see how Noctuas customer service department works? I have Noctuas in other builds and Ive never had issues but these things happen I guess. Well in any case, being down a fan these still cool off my system. Its cooling a 9900k @5.2Ghz, and Im seeing temps around 85c.

> 3 dayRunning Right now on custom settings. Very good fan for its price, not to mention the warrantee.

> 3 dayMy case is setup with 3x 140mm intake fans so I bought this for use as an exhaust. Up to about 1200 RPM its very quiet. At 2k its mid level noisy but thats mostly actual air movement not the fan itself. This thing will ruffle your hair going all out.

Greater than one weekHad an even higher static pressure than I expected, and is the quietest fan in the case.

> 3 dayLets get one fact out first. as of this writing, there arent that many options for radiator optimized high static pressure 140mm fans out there.

> 3 dayI dont know where people get the idea that these are quiet. These are very loud even at 30% RPM. These fans were simply no better than your standard case fans.

> 3 dayAdded mine to the back of my case and it dropped my GPU temps at load about 5 Celsius. It isnt terribly loud either. It doesnt have a whine like some of my stock fans do. Id recommend to anyone whos looking to cool their PC some more.
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 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 ensures an MTTF of over 150.000hrs. Topped off with Noctua’s trusted reliability, the NF-A14 industrialPPC is an ideal choice for highly demanding applications that require superior flow rates and ultimate dependability.
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.

2000rpm industrialPPC versionThanks 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 designWhile 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. |
IP52 water- and dust protectionThanks 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. |
Fibre-glass reinforced polyamide constructionBoth 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. |
Please Note:
The industrialPPC models are high-speed fans for industrial applications. As such, they are not as quiet as other Noctua fans and less suited for low-noise PC builds.
