Award-winning A-series design with Flow Acceleration Channels and Advanced Acoustic Optimisation frame for superior quiet cooling performance Large 200mm diameter for high airflow performance at extremely low noise levels, three sets of mounting holes (154x154, 170x170 110x180mm) Includes anti-vibration mounts, fan screws, Low-Noise Adaptor, extension cable and y-cable for running two PWM fans on the same header Product Description 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. Award-winning Noctua quality in 20cm size While more and more PC cases support 20cm intake, side-panel or exhaust fans, many of the bundled stock units and available aftermarket options are of questionable quality. By contrast, the NF-A20 is a true premium grade solution worthy of Noctua?s award-winning A-series. Caution: As there is no fixed industry standard for the shape, thickness or hole spacing of 200mm, 220mm, 230mm or 250mm fans, compatibility can vary from case to case. Please check compatibily before purchase. A case compatibility list can be found on the Noctua website. Flow Acceleration Channels The NF-A20 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. SSO2 bearing The NF-A20 features the further optimised 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 stabilisation, precision and durability. 154mm, 110x180mm and 170mm hole spacing In order to ensure broad compatibility with today?s PC cases, the NF-A20 features three sets of mounting holes: While the 154x154mm and 110x180mm spacing allow it to replace most 200mm fans, the 170x170mm spacing is used by many 230 and 250mm fans, which can thus also be replaced by the NF-A20.
