Noctua NF-A12x25 ULN, Ultra Quiet Silent Fan, 3-Pin (120mm, Brown)

The NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctuas 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 Noctuas A-series, the NF-A12x25 is a true all-rounder that yields superb results in all types of usage, regardless of whether its in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators. The 3-pin ULN version provides super-slow 1200/900rpm speed settings for ultra-low-noise applications and highly noise-sensitive users who demand near-silent acoustics. Topped off with exceptional running smoothness, Noctuas 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-A12x25s impeller is made from Noctuas novel Sterrox liquid-crystal polymer (LCP) compound that features extreme tensile strength, an exceptionally low thermal expansion coefficient and damping characteristics that are ideal for reducing resonance and vibration phenomena in advanced fan-blade designs.
