Having received more than 100 awards and recommendations from international hardware websites and magazines, Noctua’s flagship model NF-A12x25 has established itself as a true deluxe choice when it comes to premium-quality quiet 120mm fans. Various state-of-the-art technologies and a record tight tip clearance of only 0.5mm, which is made possible by using the novel Sterrox liquid-crystal polymer material, allow it to achieve superb results in all types of usage: 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 NF-A12x25 is a proven winner. The 4-pin LS-PWM version is a low-speed, PWM-enabled variant that is ideal for semi-passive setups or ultra-low-noise applications that require near-silent acoustics and PWM based speed control. 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.
