The NF-S12B is the successor of the outstandingly successful NF-S12. Noctuas further improved SCD2 technology as well as the highly optimized blade geometry with bevelled blade tips make this the Silent fan of the next generation which has up to 10% higher Airflow efficiency over its manifold-awarded predecessor. Noctuas well-tried SSO bearing, 6 years warranty as well as the widely spred speed options (1200/800/600rpm) make the NG-S12B FLX a true premium fan which offers maximum flexibility for quiet or even ultra-silent case cooling.
