NF-P12 The NF-P12 has been specifically developed for applications such as CPU coolers that demand superior pressure and airflow performance. Thanks to psychoacoustic optimizations like the Vortex-Control Notches, the new SCD drive system and Noctua's premium-grade SSO-Bearing, the NF-P12 achieves exceptional quietness and long-term stability. Pressure-optimized Nine-Blade Design Specifically developed for high-impedance applications such as CPU coolers, water-cooling radiators or cases with tight fan grills, the NF-P12 provides superior pressure and airflow performance. Vortex-Control Notches Psychoacoustic optimizations like the staggered Vortex-Control Notches make the NF-P12 surprisingly quiet. Smooth Commutation Drive The NF-P12's new drive system reduces torque variations and thereby ensures improved running smoothness. Self-stabilizing oil-pressure bearing Noctua's well proven SSO-Bearing technology guarantees supremely quiet operation and exceptional long-term stability.
