TECHNICAL DATA:

The NF-A14 is a high-quality, square-frame 140mm silent fan that meets the standard of Advanced Acoustic Optimization AAO Advanced Acoustic Optimization  ) from Noctua. Thanks to its  square shape  and 140mm mounting holes (124.5mm spacing) it is ideal for use with liquid cooling radiators or as an upgrade for 140mm case fans. Since it has its own characteristics of a sophisticated aerodynamic design such as  Flow Acceleration Channels , the NF-A14 increases the recognized silent dissipation performance of the NF-P14 that has been so awarded. The PWM version uses the  NE-FD1 IC specially designed by Noctua for a fully automatic speed control via 4-pin fan connectors and is equipped with a Noise Reduction Adapter that reduces the maximum speed from 1500 to 1200 rpm during PWM control. Its 1500 rpm maximum speed and performance-oriented total speed control options make the NF-A14 PWM an ideal choice for users who strive to find the perfect balance between excellent cooling capacity and quiet operation, whether in liquid cooling radiators, in heatsinks or in case ventilation.

Beating the award-winning NF-P14

The NF-P14 fan has become the quintessential choice among PC enthusiasts looking for high quality 140mm silent fans. Thanks to its deep aerodynamic optimization, the NF-A14 provides higher static pressure and even better noise airflow rate than its acclaimed predecessor.

140mm square frame

The NF-A14 with 140mm square frame and 140mm mounting holes (124.5mm spacing) is a high-end replacement for 140mm case fans and is perfect for use with liquid cooling radiators 140 mm, since its square shape guarantees full coverage and the best pressure performance.

Flow Acceleration Channels

The rotor of the NF-A14 has Flow Acceleration Channels on the suction side. By increasing the speed of the air flow in the crucial outer regions of the blades, this measure reduces the separation of the flow on the suction side and thus resulting in greater efficiency and lower vortex noise.

AAO frame

The frames with Advanced Acoustic Optimization AAO (Advanced Acoustic Optimization) of Noctua have integrated anti-vibration panels in addition to proprietary Noctua technologies such as Stepped Inlet Design (step input design) and Inner Surface Microstructures (internal surface microstructures) that perfect the efficiency of performance by fan noise.

Stepped Inlet Design

The Noctua Stepped Inlet Design adds turbulence to the inflow to facilitate the transition from laminar flow to turbulent flow, which reduces the tonal input noise, improves the adhesion of the flow and increases the flow suction capacity, especially in confined space environments.

Inner Surface Microstructures (Internal Surface Microstructures)

When the tips of the fan blades pass through the delimiter layer created by the Inner Surface Microstructures, the separation of the flow with respect to the suction side of the blades is significantly suppressed, reducing the blade rotation noise and improving the air flow and pressure efficiency.

Anti-Vibration Pads (Integrated Anti-Vibration Panels)

Integrated Anti-Vibration Panels made of extra soft silicone that minimize the transmission of small vibrations while maintaining full compatibility with all standard screws and other mounting systems.

SSO2 bearings

The NF-A14 has the recognized Noctua second generation SSO optimized bearings. With SSO2, the rear magnet is located closer to the shaft to provide greater stability, precision and durability.

Metal bearing

In order to ensure the highest possible degree of precision in its manufacture, a minimum tolerance and excellent long-term stability, the NF-A14 uses a CNC milled bearing made entirely of brass.

WM IC of own design with SCD (Soft Switching Unit)

With full support for automatic PWM speed control, the NF-A14 PWM uses the new Noctua-designed NE-FD1 PWM IC that integrates with Smooth Commutation Drive (SCD). By providing smoother torque pulses, the SCD decreases the noise of PWM shifts and makes the fan run quieter at low speeds.

Low-Noise Adapter (Noise Reduction Adapter)

The NF-A14 PWM comes with a Low-Noise Adapter LNA (noise reduction adapter) that reduces the maximum fan speed from 1500 to 1200 rpm. The LNA can be used both to use the fan at a fixed speed of 1200 rpm and to set a maximum speed when using the automatic PWM control.

Extensible Wiring Options

The 20cm main short cable of the fan minimizes the cable mess in typical situations while the supplied 30cm extension cable allows extra reach when necessary. Both cables are fully lined.
