NF-A14 INDUSTRIALPPC-24V-3000 SP IP67 PWM
Conceived for industrial heavy-duty applications requiring enhanced cooling performance and advanced ingress protection, the NF-A14 industrialPPC (Protected Performance Cooling) is a rugged, high-speed version of the award-winning retail model. The 24V SP variant uses Noctua’s new NE-FD5 high-efficiency single-phase motor driver IC to support 24V-based industrial and automotive applications.
Its sophisticated inrush current suppression and extreme electrical robustness with extended burst and surge immunity allow it to operate safely in sensitive or hostile electronic environments. Thanks to the outstanding aerodynamic efficiency of the NF-A14 design and the high-performance single-phase motor, the industrialPPC SP version provides superior airflow and pressure capacity while keeping noise and power consumption at a moderate level 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 surroundings, the renowned SSO2 bearing technology guarantees an MTTF of over 150,000 hours. Topped off with Noctua’s trusted reliability and 6-year manufacturer’s warranty, the NF-A14 industrialPPC is an ideal choice for highly demanding applications that require superior flow rates and ultimate dependability.
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 worldwide.
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, the fan is ideal for challenging industrial applications.
The industrialPPC 24V SP models use Noctua's new NE-FD5 high-performance single-phase PWM motor driver IC. Thanks to its excellent commutation efficiency, the NE-FD5 enables the SP versions to achieve exactly the same performance as previous models with three-phase motors.
While the industrialPPC 24V model has been designed with 24V industrial applications in mind, it runs at a maximum speed of around 1100rpm in 12V PC environments. It can be slowed down further via PWM, thus combining industrialPPC features and design with Noctua's signature quietness.
The fan uses Noctua's custom-designed NE-FD5 PWM IC for 24V single-phase motors to support fully automatic PWM speed control. The NE-FD5 provides excellent energy efficiency and integrates Noctua's proprietary Smooth Commutation Drive (SCD) technology, suppressing PWM switching noise and thus making the fan quieter at lower speeds.
Meeting stringent requirements for burst and surge protection, the 24V SP version's high electrical robustness permits the fan to be used in automotive projects and in other harsh environments with transients from electric motors and other inductive switching loads.
The fan's voltage-stabilised inrush current suppression provides a smooth power-up and dramatically reduces power line transients that otherwise could affect other electronic components connected to the power line. This makes the fan safe to use in sensitive electronic environments.
The motor and PCB of the IP67 version are entirely cast in a special, highly heat-conductive resin that combines thoroughgoing protection and effective motor heat dissipation. Complying with the ingress protection rating IP67, this fan is fully dust-tight and completely waterproof up to 1m water depth.
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, making the fans even more robust and break-proof than Noctua's standard fibre-glass reinforced PBT fans.
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.
Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads and Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, which further refine the fan's performance/noise efficiency.
Noctua's Stepped Inlet Design adds turbulence to the influx 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.
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 made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
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 for better stabilisation, precision and durability.

Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A14 industrialPPC features an MTTF rating of over 150.000 hours and a full 6-year manufacturer's warranty.
