Having received more than 100 awards and recommendations from international hardware websites and magazines, Noctuas 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 its 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.
