> 3 dayI use 2 of these in my case with my AIO corsair water cooler and radiator. These use PWM power managment so I use my motherboard to manage fan speeds based on CPU temps. This really is the best way to do it. I use a customized fan curve on my mobo. These say pretty silent until you get about to 75% of its top speed. But its more of a whoosing sound. Mostly due to air movement than from the fans themselves.

> 3 dayExpensive for a single fan but its worth it for the silence, they are able to move A LOT of air before becoming audible.

14-06-2025The fans push a ton of air, more than any fan ive ever owned, but at high RPM made a loud hissing or buzzing sound, I tried different power setups and could not get rid of the buzzing, at lower RPMs there is little to no buzzing but about 1400+ it gets louder and louder until it is louder than the actual fan or air moving through. They are very expensive at 30 bucks a pop and I was expecting more.

> 3 dayused these on my computer AIO cooler in place of the loud fans that came stock. These fans have a way higher static PSI and are much Quieter than the stock fans

Greater than one weekUsed Noctua fans for `bout six years, these have better cfms and static pressure than my originals. Bought to replace the stock Corsair H115i radiator fans after investigating them.

Greater than one weekI ordered these fans to replace my Corsair H115i’s stock rad fans. They sit above the top bracket to which my rad is mounted and I am speechless. I thought the idle noise I heard was the front intakes...turns out it was the stock SP140MM fans. When I swapped them, I actually put my ears up to the vent to make sure they were spinning. I am serisouly at a loss for words. Not only do these fans keep the rig 4-5 degrees cooler, they are silent. These were the best investment I have made into this rig post-build. I am very pleased by the performance.

> 3 dayThese are worth it! They are fast and cold as ice! The airflow in my case is amazing and I k my have two if these with 3 other Corsair fans, although I am thinking of replacing the other fans with these, I will be ordering one more for sure to install on the top of the tower! Great product and keeps everything cool!

> 3 dayGot 3 fans delivered and all 3 of them are covered in dirt and glue, clearly used. The packaging wasn’t even that bad so I’m confused as to how these even were shipped as new product. I submitted for replacement fans and if the next ones that are delivered are clean I’ll change my review.

> 3 daybest fan quite at lower rpms and lets you really ramp them up to get huge air flow
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.
