Noctua NF-A12x25 LS-PWM fan

With more than 100 recommendations and awards from international hardware websites and magazines, Noctua's flagship model NF-A12x25 has become an established reference for quiet 120 mm premium fans. Innovative aerodynamic design measures, along with an unprecedentedly tight impeller gap of just 0.5 mm made possible by the use of the new Sterrox® liquid crystal polymer, ensure excellent results in all application areas: whether for performance-oriented applications with low static pressure, such as case ventilation, or pressure-oriented scenarios with high airflow resistance, such as use on coolers and water cooling radiators. The 4-pin LS-PWM version is ideal for semi-passive systems and silent applications that require virtually silent operation and PWM-based speed control, thanks to PWM support and particularly low speeds. The overall package is rounded off by Noctua's reference-class SSO2 bearings, a rich accessory package, and a 6-year manufacturer's warranty. Its superior efficiency, forward-thinking design, and uncompromising material choice make the NF-A12x25 a true premium product for the highest demands.
