ENCLOSURES

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 Channels and 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. a rich bundle of accessories and 6-year manufacturer’s warranty. 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.
