The NF-A12x25 is a highly optimized 120 mm fan of the next generation, setting new benchmarks in silent cooling performance thanks to innovative aerodynamic design measures. It combines pioneering Noctua technologies such as the Advanced Acoustic Optimization frame and Flow Acceleration Channels with an unprecedentedly tight rotor gap of just 0.5 mm. The manufacturing precision required for this is ensured by the use of the new Sterrox liquid crystal polymer and metal reinforcements at the hub and shaft mount. In line with Noctua's A-series concept, the NF-A12x25 is a true all-rounder, delivering excellent results in all application areas—whether for performance-oriented applications with low static pressure like case ventilation or pressure-oriented scenarios with high airflow resistance such as use on coolers and water cooling radiators. The 3-Pin FLX version offers three speed settings (2000/1700/1350 rpm) via the included low-noise adapters, providing full flexibility between maximum cooling performance and near-silent operation. Its superior efficiency, forward-thinking design, and uncompromising material choice make the NF-A12x25 a true premium product for the highest demands.
