The NF-A20 is a highly optimised, premium quality quiet 200mm fan. Featuring an AAO (Advanced Acoustic Optimisation) standard frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A20 brings the renowned quiet cooling performance of Noctua’s award-winning A-series to the increasingly popular 20cm form factor. The PWM version uses Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers, which allows it to strike a perfect balance between quietness and ventilation performance in each given situation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make the NF-A20 an elite choice for the highest demands.
