Noctua NF-A12x25 PWM

The NF-A12x25 is a highly optimized 120mm fan of the next generation, integrating Noctua's latest innovations in aerodynamics to achieve previously unmatched cooling performance. It utilizes cutting-edge technologies such as the Advanced Acoustic Optimization frame and Flow Acceleration Channels, combined with a record peak gap of just 0.5 mm. This is made possible by the use of the novel Sterrox liquid crystal polymer (LCP) as well as a metal-reinforced motor hub and shaft for maximum precision. Following the Noctua A-series approach, the NF-A12x25 is a true all-rounder that delivers excellent results across all types of applications, whether they are low-resistance, airflow-oriented tasks like case cooling or high-performance applications. It is also suitable for pressure-demanding scenarios such as on heatsinks and water coolers. The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a low-noise adapter to reduce the maximum speed from 2000 to 1700 RPM. Equipped with exceptional smooth operation, Noctua's SSO2 reference bearing, a rich accessory package, and a 6-year manufacturer’s warranty, the NF-A12x25 is a premium quality product through and through. Its superior efficiency, state-of-the-art design, and groundbreaking materials make it an elite choice for the highest demands.
