Noctua NF-A9 PWM Case Fan, 92 mm, Beige/Brown

The NOCTUA NF-A9 PWM is a 92 mm case fan engineered for thermal performance in noise-sensitive PC builds. It incorporates Noctua’s SSO2 bearing system, which uses a magnet to support self-stabilization of the rotor axis for improved precision and operational longevity. The fan's frame and blade geometry are designed to generate high static pressure, making it suitable for applications with significant airflow impedance. This includes use on CPU heatsinks, water-cooling radiators, or in computer cases with restrictive dust filters and grilles.

Equipped with a 4-pin connector, this fan supports Pulse Width Modulation (PWM) for automatic speed control through the motherboard. This function allows the fan to run at lower speeds during idle periods and increase its RPM as system temperatures rise. At its maximum rotational speed of 2000 RPM, the fan moves up to 46.44 CFM of air at a noise level of 22.8 dB(A). An included Low-Noise Adaptor can be attached to reduce the maximum speed and lower the acoustic output to 16.3 dB(A).
