The Noctua NF-A12x25 FLX is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering to achieve an unprecedented level of quiet cooling performance. It features state-of-the-art technologies such as the AAO (Advanced Acoustic Optimisation) frame, Flow Acceleration Channels, and a record tight tip clearance of only 0.5mm, enabled by the novel Sterrox® liquid-crystal polymer (LCP) compound, metal-reinforced motor hub, and axis for ultimate precision. The 3-pin FLX version provides flexible speed settings of 2000/1700/1350 RPM via supplied Low-Noise Adapters, allowing fine-tuning for maximum airflow or near-silent operation. It excels in high airflow and static pressure, ideal as a case fan, for CPU coolers, watercooling radiators, and AIO liquid cooling systems, with exceptional running smoothness and Noctua’s reference-class SSO2 bearing.
