Noctua NF-A14 PWM 产品宣传页
www.noctua.at
The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. Its square shape and
140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling radiators or as an upgrade for 140mm case fans. Featuring sophisticated aerodynamic design
measures such as Flow Acceleration Channels, the NF-A14 further improves the renowned quiet cooling performance of the award-winning NF-P14. The PWM version sports
Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM
control from 1500rpm to 1200rpm. Its performance-oriented 1500rpm top speed and comprehensive speed control options make the NF-A14 PWM an elite choice for users
who strive to strike a perfect balance between excellent cooling capacity and superb quietness of operation, be it on watercooling radiators, on heatsinks or in case ventilation.

Succeeding the award-winning NF-P14
Noctua’s NF-P14 fan has become a default-choice among PC enthusiasts looking for a premium qua-
lity quiet 140mm fan. Thanks to its thoroughgoing aerodynamic optimisations, the NF-A14 provides
higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor.

Square 140mm frame
The NF-A14’s square 140mm frame with 140mm mounting holes (124.5mm spacing) makes it a
premium grade replacement for common 140mm case fans and perfect for use on 140mm water
cooling radiators, where its square shape will ensure full coverage and best pressure performance.

Flow Acceleration Channels
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.

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

Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-A14 PWM uses Noctua’s novel, custom
designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing
smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter
at low speeds

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

Low-Noise Adaptor
The NF-A14 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan
speed from 1500 to 1200rpm. The L.N.A can be used either to run the fan at a fixed speed of
1200rpm or to cap the maximum speed when using automatic PWM control.

1200rpm or to cap the maximum speed when using automatic PWM control.
Inner Surface Microstructures
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.
