Noctua NF-A14 iPPC-3000 PWM Fan

Noctua NF-A14 iPPC-3000 PWM Fan

Conceived for industrial heavy-duty applications that require enhanced cooling performance and advanced ingress protection, the NF-A14 iPPC-3000 PWM (Protected Performance Cooling) is a ruggedized high-speed version of the award-winning retail model. Thanks to the outstanding aerodynamic efficiency of the NF-A14 iPPC-3000 PWM 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 fiber-glass reinforced polyamide construction and certified water and dust protection make the NF-A14 iPPC-3000 PWM suitable for operation in challenging environments, the renowned SSO2-bearing technology guarantees an MTTF of over 150.000hrs.

Award-winning NF-A14 design

Having received more than 100 awards and recommendations from the international press, Noctua’s NF-A14 iPPC-3000 PWM 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 iPPC-3000 PWM 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 iPPC-3000 PWM 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 to 2000rpm.

Fiberglass-reinforced polyamide construction

Both the impeller and the frame of Noctua’s industrialPPC fans are made entirely from fiber-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 fiber-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 iPPC-3000 PWM 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 iPPC-3000 PWM 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 plowing 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 minimize 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 optimized 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 stabilization, 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

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.
