Antec NOVA 120 PWM 3-Phase Speed Controller Fan (3-Pack) offers a premium cooling solution featuring advanced motor technology and durable construction designed for optimal PC airflow control.

• Three-Phase PWM Speed Controller: Allows switching among three distinct speed modes (Low, Medium, High) to tailor cooling performance to your hardware needs. The fan halts operation when the PWM signal is below 6%, ensuring energy efficiency.
• Powerful Three-Phase Six-Pole Motor: Delivers greater torque and excellent starting performance while reducing energy loss, noise, and vibration with a precise PWM closed-loop design.
• Premium Build Quality: Constructed from industrial-grade Liquid Crystal Polymer (LCP) for blades and frame, paired with a metal shaft and neodymium magnet for enhanced reliability and vibration stability at high speeds.
• Dustproof & Anti-Vibration Design: Internal drive components are protected against dust ingress, extending lifespan. The exterior geometric ribs enhance frame rigidity, while eight rubber pads and optimized blade design minimize vibration and resonance.
• Performance Specs:

• Connectivity & Power: Features a 4-pin PWM connector compatible with most modern motherboards, rated 12 V DC with operational voltage between 6.0 and 13.2 V, max current 0.35 A.
• Additional Features: Supports PWM sharing/daisy-chaining to control multiple fans from one header. Backed by a 5-year warranty.
