The Antec NOVA 120 PWM Fan with Speed Controller delivers exceptional cooling performance, precision control, and durability. Designed with a three-phase PWM speed controller, it offers adjustable speed modes to adapt to different hardware environments and workloads. The fan can even cease operation when the PWM signal drops below 6%, enhancing energy efficiency and reducing wear during low-demand periods. Its computational fluid dynamics (CFD)-optimized 9-blade design ensures superior airflo
