Computer case Fan 12 cm 800 RPM. 8.6 dB 0.62 mmH2O. Brown. The NF-S12A marks the third generation of Noctua s signature S12 series quiet case fans, which have received more than 250 awards and recommendations from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic Optimisation) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The ULN version provides super-slow 800/600rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand near-silent operation. Its superb running smoothness, SSO2 bearing and Noctua s trusted premium quality make it an elite choice for quiet case cooling. Performance. Mean time between failures (MTBF). 150000 h.
