> 3 dayNeeds a powerful PWM signal to spin, I cant daisychain the PWM through any other fans, even if Im drawing the power from elsewhere. 5 corsair fans will run off that PWM signal, but I cant run any one of them at the same time as this fan.

Greater than one weekExpensive for a single fan but its worth it for the silence, they are able to move A LOT of air before becoming audible.

> 3 dayA bit loud at full speed (31dB) but it moves A LOT of air and has great static pressure at that speed.

> 3 dayI purchased 2 of these for a fan overhaul after getting a 3090ti. The airflow from the 2 fans was great, better then any fans Ive had in the past. Unfortunately they were pretty loud even after playing with the fan settings and trying to quiet them down. They are truly heavy duty and work great if airflow is your main goal. I wanted a good balance of air flow to noise so I ended up returning them and going with another option.

> 3 dayThese fans are much quieter than the stock case fans and put out a lot more air. A big difference.

> 3 dayNoctua in black, perfect. I added red Chromax vibration pads and have this as exhaust in my PC. It move almost as much air as the 200mm intake in the Phanteks case and I set a speed curve so it never goes over 60% and my system still stays super quiet.

> 3 dayI used these fans for the first time as replacements for the stock fans of the corsair hydro series water cooler. These fans are dead quiet, move the air, and are in a word SUPERB! If not the best fans out there they are darn close.

> 3 dayQC issues. Noctua will replace bad fans without a question. They need to be worn in a bit before they get a bit quieter. Great performance. Ugly (but you can change that). Crazy strong frame

Greater than one weekI 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.
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.
