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

The Noctua NF-S12B redux-1200 PWM is a 120 mm fan designed for PC case ventilation. Its primary function is to move air through a chassis to cool internal components, supporting front-to-rear or bottom-to-top airflow configurations. The fan's rotational speed is adjustable from 400 to 1200 RPM via its 4-pin PWM connector. This connection allows a motherboard or dedicated fan controller to regulate its speed automatically based on system temperatures, balancing cooling performance with acoustic output.

This model is part of Noctua's redux series, which reissues established fan designs in a streamlined package. It incorporates a Self-Stabilising Oil-pressure (SSO) bearing, engineered for long-term operational stability and durability. At its maximum speed, the fan generates an airflow of 59.2 CFM with a corresponding noise level of 18.1 dB. The standard 120 x 25 mm frame ensures compatibility with common case mounting points for either intake or exhaust applications.
