Noctua NF-A12X25 PWM

- The NF-A12 is a 120 mm fan designed for heavy duty applications - It can spin at 2000 rpm and pump out incredible airflow to cool industrial machines- Its metal-reinforced motor hub provides extra stability for long-term use and smooth performance- Thanks to PWM control, the fan only turns on and speeds up when it needs to

The NF-A12x25 is a highly optimized next-generation 120mm fan that, thanks to innovative aerodynamic design measures, sets new records in terms of silent cooling performance. It combines trend-setting Noctua technologies such as the AAO (Advanced Acoustic Optimization) frame or Flow Acceleration Channels with an unprecedentedly narrow impeller gap... moreof just 0.5mm. The manufacturing precision required for this is guaranteed by the use of the new Sterrox® liquid crystal polymer and metal reinforcements on the hub and axle mount. In line with the design of Noctua´s A series, the NF-A12x25 is a real all-rounder that achieves excellent results in all areas of applicationshows - regardless of whether it is a question of flow rate-oriented applications with low dynamic pressure such as housing ventilation or pressure-oriented scenarios with high air resistance such as use on coolers and water-cooling radiators. The 4-pin PWM version supports fully automatic speed control via PWM connections and comes with a low-noise adapter, which allows the maximum speed in PWM operation to be reduced from 2000 to 1700rpm. The overall package is rounded off by Noctua´s reference- class SSO2 bearing , a comprehensive accessories package and a 6-year manufacturer´s guarantee. Its superior efficiency, forward-looking design and uncompromising choice of materials make the NF-A12x25 a real premium product for the highest demands.Features: Next-generation performance: - Noctua´s renowned 120mm models such as the NF-F12 and NF-S12A have received more than 400 awards and recommendations from international specialist publications and are considered among the best fans on the market. With its even higher efficiency and its new, state-of-the-art construction, the NF-A12x25 represents a further innovation push in terms of performance level and manufacturing technology.Highly optimized P/Q curve for all applicationsHighly optimized P/Q curve for all applications: - The advanced aerodynamic design of the NF-A12x25 enables an extremely strong pressure-flow rate characteristic (P/Q) especially in the critical middle range . This makes the NF-A12x25 a real all-rounder that works excellently in both pressure-sensitive and flow rate-sensitive applications.Excellent application acoustics: - While many fans generate unpleasant, high-pitched running noises as soon as they are installed in typical applications such as coolers or radiators, the NF-A12x25 has been carefully optimized for optimal application acoustics: Even with high dynamic pressure, the fan convinces with an even, pleasant frequency profile and surprisingly low sound pressure levels.Flow Acceleration Channels: - The impeller of the NF-A12x25 is equipped with so-called Flow Acceleration Channels on the suction side. By accelerating airflow in the critical outer regions of the fan blades, suction-side vortex shedding is reduced, resulting in higher efficiency and lower turbulence-related noise emissions.Minimum impeller
