A combination of 11 stator blades with the specially developed seven-bladed rotor and the Focused Flow™ system achieves the excellent static pressure of the NF-F12 and focusses the airflow for superior cooling performance on air coolers and radiators. At the same time the advanced aerodynamic design as well as the SSO bearing of the second generation and Noctua's newly designed PWM IC for fully automatic control make for an impressively low noise emission level. The NF-F12 offers a modular cable system, integrated anti-vibration pads as well as two speed settings for maximum flexibility. Its impressive performance, extensive features and Noctua's proven premium quality make the NF-F12 an exquisite choice for air coolers, radiators and other pressure-sensitive applications.
