Noctua NF-A12x25 PWM 120x120x25

The NF-A12x25 is an optimized, next-generation 120mm fan that integrates Noctua's latest innovations in aerodynamic engineering for an unprecedented level of silent cooling. It uses cutting-edge technology, such as the AAO (Advanced Acoustic Optimization) frame or Flow Acceleration Channels and combines them with an incredibly narrow distance between the tip of the blade and the case, only 0.5mm, which has been made possible thanks to the use of the innovative compound Sterrox® liquid crystal polymer (LCP) as well as a metal-reinforced drive shaft and bushing for maximum precision. Following Noctua's A-series approach, the NF-A12x25 is a completely versatile fan that offers extraordinary results in all its uses, regardless of whether they are low-impedance and airflow-oriented applications, as is the case of refrigeration; or in high-impedance scenarios that require pressure, such as liquid cooling heatsinks or radiators. The 4-pin PWM version provides full automatic speed control via the PWM connectors and is equipped with a noise reduction adapter that can reduce the maximum speed from 2000 to 1700 rpm. Equipped with the Noctua SSO2 bearing, a reference in the market and exceptionally smooth operation, a wide range of accessories and a 6-year manufacturing warranty, the NF-A12x25 is a high quality product in all cases. Its great efficiency, avant-garde construction and pioneering materials make it a top quality choice for the most demanding.

Noctua 120mm fans like the NF-F12 and NF-S12A are known as some of the best on the market and have received more than 400 awards and recommendations from the international press. Thanks to its improved efficiency and engineering, the NF-A12x25 represents a step forward in performance and manufacturing.

The sophisticated, aerodynamic design of the NF-A12x25 supports an exceptionally strong pressure-flow (P/Q) curve in the critical mid-section. Which means that the NF-A12x25 is an absolutely versatile fan with excellent performance in both applications requiring static pressure and air flow.

While other fans make unpleasant, high-pitched sounds when installed in typical applications such as coolers or radiators, the loudness of the NF-A12x25 has been carefully tuned for optimal application acoustics. It delivers a smooth, pleasant frequency curve and surprisingly low sound pressure levels (SPL) when operating back pressure.

The impeller of the NF-A12x25 has flow acceleration channels on the suction side. By accelerating the airflow on the most important outer part of the blades, the flow separation on the suction side is reduced and, therefore, better efficiency and lower vortex noise are achieved.

The NF-A12x25 has a distance between the tips of the blades and the frame of only 0.5 mm. This ambitious design sets a new benchmark for 120mm fans and helps the NF-A12x25 operate more efficiently under back pressure, such as in heatsinks or radiators, as flow loss through the gap between the fan is reduced. rotor and frame.
