The NF-A12x25 is a highly optimized 120mm fan of the next generation, which sets new record in terms of silent cooling performance thanks to innovative aerodynamic design measures.
It combines trend-setting Noctua technologies such as the AAO (Advanced Acoustic Optimization) frame or Flow Acceleration Channels with an unprecedented narrow wheel gap of only 0.
5mm.
The manufacturing precision required for this is ensured by the use of the new Sterrox® liquid crystal polymer as well as metal reinforcements on the hub and axle support.
According to the concept of Noctuas A-series, the NF-A12x25 is a real all-rounder, which shows excellent results in all application areas – no matter whether it concerns flow-performance-oriented applications with low back pressure such as housing ventilation or pressure-oriented scenarios with high air resistance such as the use on coolers and water cooling radiators.
The 4-pin PWM version supports fully automatic speed control via PWM connections and is delivered with a low-noise adapter, through which the maximum speed in PWM operation can be reduced from 2000 to 1700rpm.
The complete package is rounded off by Noctua's reference class bearing SSO2, as well as a comprehensive accessory package.
Its superior efficiency, forward-looking design and uncompromising choice of materials make the NF-A12x25 a real premium product for the highest demands.
Next-generation performanceNoctuas renowned 120mm models such as the NF-F12 and NF-S12A have received more than 400 awards and recommendations from international trade publications and are counted among the best fans on the market.
With its even higher efficiency and its innovative, state-of-the-art design, the NF-A12x25 represents a further innovation boost in terms of performance level and manufacturing technology.
Highly optimized P/Q characteristic curve for all applicationsThe advanced aerodynamic design of the NF-A12x25 enables an extremely strong pressure-output characteristic curve (P/Q), particularly in the critical mid-range.
This makes the NF-A12x25 a real all-rounder, which functions excellently in pressure-sensitive as well as in conveyor-power-sensitive applications.
Excellent application acousticsWhile many fans produce unpleasant, high-tone running noises as soon as they are mounted in typical applications such as coolers or radiators, the NF-A12x25 has been carefully optimized for an optimum application acoustics: Even with high pressure, the fan impresses with a uniform, pleasant frequency profile and surprisingly low sound pressure levels.
Flow Acceleration ChannelsThe impeller of the NF-A12x25 is equipped with so-called flow acceleration channels on the suction side.
By accelerating the airflow in the critical outer regions of the fan blades, suction-side eddy solutions are reduced, resulting in higher efficiency and a lower turbulence-related noise emission.
Minimum wheel gapThe NF-A12x25 has an unprecedented narrow wheel gap (distance between blade tips and inside frame) of only 0.
5mm.
This extremely ambitious design represents a new record for 120mm fans and contributes to the superior performance at higher back pressure as on coolers and radiators, because there is less leakage through the gap between rotor and frame.
Metal reinforced hub areaThe central hub area of the NF-A12x25 is made entirely of steel and the axle housing has an additional brass reinforcement.
The combination of these two measures ensures ultimate precision and even better stability in the critical hub area.
Sterrox® liquid crystal polymerThe rotor of the NF-A12x25 consists of Noctuas novel Sterrox® liquid crystal polymer (LCP), which is characterized by extreme tensile strength, an exceptionally low thermal expansion coefficient as well as an excellent damping characteristic, which is ideal for reducing resonance and vibration phenomena i
