Noctua NF-A12x25 G2 PWM FAN

The Noctua NF-A12x25 G2 PWM represents a major leap forward in the evolution of high-performance 120 mm cooling fans. Designed with advanced Austrian engineering, the second-generation model refines nearly every aspect of the original award-winning NF-A12x25. Its newly enhanced Sterrox® LCP Gen2 impeller offers exceptional rigidity and stability, minimizing blade deformation even at high rotational speeds and ensuring superior consistency in airflow performance.

With an extremely tight 0.5 mm clearance, optimized aerodynamic shaping, improved flow-acceleration zones, and a finely tuned pressure/airflow curve, this fan delivers outstanding cooling performance in all scenarios. Whether installed on water-cooling radiators, high-end tower coolers, or compact cases, the NF-A12x25 G2 PWM offers remarkable static pressure, excellent airflow output, and exceptionally low noise levels.

PWM modulation allows precise control from 0 to 1800 RPM, achieving near-silent operation when idle and powerful cooling under load. The proven SSO2 bearing system ensures long-term reliability and a service life far beyond typical PC fans.

As one of Noctua’s official retail partners in Vienna, Techmann offers customers the opportunity to examine and test the fan in-store, as well as purchase it online with full warranty and guaranteed authenticity.
