Noctua NF-S12B Redux-1200 PWM Case Fan, 120 mm, Grey

The Noctua NF-S12B redux-1200 PWM is a 120mm case fan designed for low-impedance airflow applications. It incorporates a Self-Stabilising Oil-pressure (SSO) bearing to promote consistent and quiet operation over an extended lifespan. The fan supports Pulse-Width Modulation (PWM) through a standard 4-pin connector, enabling motherboards or dedicated fan controllers to automatically regulate its speed based on system temperatures. This model is constructed for users who prioritize reliable case ventilation without integrated lighting effects.

At its maximum rotational speed of 1200 RPM, the fan is rated to deliver an airflow of 59.2 CFM with a static pressure of 1.31 mmH2O. The acoustic output under these conditions is specified at 18.1 dB. Its standard 120 x 120 x 25 mm form factor ensures compatibility with common fan mounts in most PC cases. The fan is constructed from PBT GF30 thermoplastic and is supplied with four mounting screws for installation.
