Noctua NF-A12x25 G2 PWM Fan, SSO2 Bearing, 120mm, Beige

This 120 mm cooling fan is designed to provide balanced performance across both airflow and static pressure applications, making it suitable for standard case ventilation or integration with radiators and heatsinks. The unit operates at a maximum rotational speed of 1800 RPM, generating an airflow of 107.3 m³/h and a static pressure reading of 3.14 mmH2O. Construction incorporates specialized materials, including Sterrox Liquid Crystal Polymer (LCP) for the impeller blades, intended to minimize resonance and structural deformation during operation.

Speed control is managed via a 4-pin Pulse Width Modulation (PWM) connection, enabling dynamic adjustment down to 0 RPM based on thermal demands. The maximum recorded noise level is 22.5 dB, offering a favorable performance-to-noise ratio for system builders prioritizing quiet operation. Utilizing the SSO2 bearing system, this fan features enhanced stability and a rated Mean Time To Failure (MTTF) of 150,000 hours, supporting long-term reliability in computing environments.
