Product Description

NF-A12x25 FLX header

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 3-pin FLX version provides 2000/1700/1350rpm speed settings via the supplied Low-Noise Adaptors so as to give full flexibility in configuring the fan for maximum cooling capacity or near-silent acoustics. 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.

I'm not going to complain about the value because like everything if you want at the tip top quality there's a big price jump, and at least with fans you can use them in your next builds ;) top quality as in heavy duty, design is unique and works better than any other fan of this size or possibly any fan, looks wise...well looks are individualistic I personally don't mind it.

Who is this for? Someone building a pc who wants no weak links and the up most effectiveness or someone who's build is small on scale and need the few fans on their rig to do more work than normal.
