The NF-A12x25 is a highly optimised, next-generation fan measuring 120 mm. The fan raises the bar for silent cooling performance thanks to the innovative, aerodynamic engineering. It combines pioneering Noctua technologies such as the AAO (Advanced Acoustic Optimisation) frame and Flow Acceleration Channels with an astonishingly narrow tip clearance of just 0.5 mm. This requires a high level of manufacturing precision - precision that is made possible by the use of the new Sterrox® liquid crystal polymer and a metal-reinforced hub and axle clamp.
In line with the design of Noctua's A-series, the NF-A12x25 is a true all-rounder that delivers excellent results in all areas of application - whether for airflow-focused applications with low back pressure such as case ventilation, or pressure-focused scenarios with high air resistance such as use on coolers and water cooling radiators.
The 3-pin ULN version offers extra-low speeds (1200/900 rpm) for ultra-low noise applications and especially noise-sensitive users who want to have virtually silent operation.
