Noctua 140mm Nf-a14 Pwm 1500rpm Fan (NF-A14-PWM)

Manufacture # Noctua  | Model # A14-PWM

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimization) 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.

Features:

• Noctua's NF-P14 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 140mm fan
• The NF-A14-PWM provides higher static pressure and an even better airflow/noise ratio
• The NF-A14-PWM square 140mm frame with 140mm mounting holes
• It a premium grade replacement for common 140mm case fans
• The NF-A14-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
• 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
• 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
• Integrated Anti-Vibration Pads made from extra-soft silicone minimize.
