Brand: Noctua

Noctua NF-A12x25 PWM Premium Quiet Fan 4-Pin (120mm Brown)
Product Description

The NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance. It takes state-of-the-art technologies such as the AAO (Advanced Acoustic Optimisation) frame or Flow Acceleration Channelsand combines them with a record tight tip clearance of only 0.5mm which is made possible by using the novel Sterrox liquid-crystal polymer (LCP) compound as well as a metal-reinforced motor hub and axis for ultimate precision. Following the approach of Noctua’s A-series the NF-A12x25 is a true all-rounder that yields superb results in all types of usage regardless of whether it’s in low-impedance airflow-oriented applications such as case cooling or high-impedance pressure-demanding scenarios such as on heatsinks and watercooling radiators. The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 2000 to 1700rpm. Topped off with exceptional running smoothness Noctua’s reference-class SSO2 bearing and a rich bundle of accessories the NF-A12x25 is a premium-quality product through and through. Its superior efficiency cutting-edge construction and pioneering materials make it an elite choice for the most discerning demands.

The NF-A12x25’s sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 is a true jack-of-all-trades with excellent performance in both static pressure demanding and airflow demanding applications.

Noctua’s 120mm fans such as the NF-F12 and NF-S12A are renowned as being among the best on the market and have received more than 400 awards and recommendations from the international press. With its further improved efficiency and novel state-of-the-art engineering the NF-A12x25 represents another step up in performance and manufacturing.

The NF-A12x25 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design sets a new benchmark for 120mm fans and helps the NF-A12x25 to work more efficiently against back pressure such as on heatsinks or radiators by reducing leak flows through the gap between impeller and frame.

The centrepiece of the NF-A12x25’s motor hub is made entirely from steel and the axle mount is reinforced with an additional brass structure. In combination both measures ensure ultimate precision and increased stability in the critical hub area.
