Noctua NF-B9 redux-1600 PWM 92 mm Case Fan - Grey

The Noctua NF-B9 redux-1600 PWM is a 92 mm case fan designed for chassis ventilation. It operates at speeds up to 1600 RPM and connects via a standard 4-pin connector, enabling Pulse-Width Modulation (PWM) for automatic speed control. This function allows a compatible motherboard or fan controller to adjust the fan's rotational speed in response to system temperatures. The frame is constructed from PBT GF30 material, which provides structural rigidity.

This fan incorporates Noctua's SSO bearing, a self-stabilising oil-pressure bearing engineered for operational stability and reduced acoustic output. With dimensions of 92 x 92 x 25 mm, it is compatible with standard 92 mm fan mounts in various PC cases, including compact builds. At its maximum speed, the fan produces an airflow of 64.3 CFM and a static pressure of 1.61 mmH2O, with a corresponding noise level of 17.6 dB. This model does not include LED illumination, maintaining a neutral grey aesthetic.
