Noctua NF-A14-PWM 140mm x 25mm 1500RPM PWM Cooling Fan
$
50
The NF-A14 is a premium quality quiet 140 mm fan with a square frame that complies with Noctua's AAO (Advanced Acoustic Optimization) standard. Its square shape and 140 mm mounting holes make it ideal for use on water-cooling radiators or as an upgrade for 140 mm 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 1500 rpm to 1200 rpm. Its performance-oriented 1500 rpm 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 water-cooling radiators, on heatsinks or in case ventilation.

Product Features
The NF-A14's square 140 mm frame with 140 mm mounting holes makes it a premium grade replacement for common 140 mm case fans and perfect for use on 140 mm water cooling radiators, where its square shape will ensure full coverage and best pressure performance.
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 Optimization) 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.
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.
With the tips of the fan blades ploghing 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 minimize the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
The NF-A14 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.
In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-A14 sports a CNC milled bearing shell made entirely from brass.
The NF-A14 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the fan speed. The L. N. A can be used either to run the fan at a fixed speed of 1200 rpm or to cap the maximum speed when using automatic PWM control.
