Noctua NF-A14X25R G2 SX2 PP, 140mm, PWM, SSO2 Bearing Fan Kit, 2-pack, Beige/Brown

This product is a dual-pack of 140 mm PC cooling fans intended for system builders requiring balanced performance across airflow and static pressure requirements. The unit operates within a rotational speed range of 0 to 1500 RPM, managed via a 4-pin PWM connection for precise speed adjustment based on thermal load. At maximum rotation, the fan achieves an airflow rate of 155.6 m³/h and delivers a static pressure of 2.56 mmH2O. This specification profile positions the fan as suitable for demanding applications, including use on restrictive components such as liquid cooling radiators or densely packed intake filters.

The fan employs Liquid Crystal Polymer (LCP) for both the frame and the impeller, a material selected to enhance structural stability and minimize resonant vibration during operation. Acoustic output peaks at 24.8 dB at full speed; utilization of the provided low-noise adapter (LNA) can reduce the noise level to 19.7 dB. Stability is maintained via the integrated SSO2 bearing system, which contributes to a rated mean time to failure (MTTF) of 150,000 hours, supporting long-term reliability in continuous operation.
