With a further refined blade design with anti-stall knobs working in concert with the AAO (Advanced Acoustic Optimization) frame, the NF-S12A improves the airflow/noise efficiency of its well-known predecessor by up to 8%. The PWM version features Noctua's custom-designed NE-FD1 IC for fully automatic speed control via 4-pin valve headers and comes with a low-noise adapter to reduce maximum speed under PWM control from 1200 to 900 rpm. Its excellent running smoothness, SSO2 bearing and Noctua's trusted premium quality make it an elite choice for quiet case cooling.
