Noctua NF-A12x25 G2 PWM Fan Kit, 120mm, Fluid Dynamic Bearing, 2-pack, Beige

This package contains two 120mm cooling fans engineered for high performance in various PC cooling applications, specifically chassis ventilation and dense radiator mounting. The fans operate across a rotational speed range configurable from 0 to 1800 RPM, utilizing a 4-pin Pulse Width Modulation (PWM) connection for speed control. At maximum operational speed, each fan is rated to deliver 63.15 CFM of airflow and generate a static pressure of 3.14 mmH₂O, supporting efficient thermal exchange even against flow resistance.

Acoustic performance is maintained at a peak output of 22.5 dB, providing a functional balance between noise generation and cooling power. Longevity is addressed through the integration of the SSO2 bearing system, which contributes to a Mean Time to Failure (MTTF) rating of 150,000 hours. The construction utilizes specialized engineering polymers, including LCP GF30 for the impeller, designed for structural rigidity. This dual-pack configuration is supplied complete with mounting hardware and specific cables, including both a splitter and an extension cable, facilitating system integration.
