Antec Nova Black 120 PWM 3-Phase Speed Controller. Low Power, High Heat Dissipation, Low Noise Ultimate Fan – 1x Fan with controller | NOVA 120

PWM 3-Phase Speed Controller
Included three-phase PWM speed controller allows you to switch modes according to different hardware environments and scenarios. Under all 3 modes Nova is able to stop operating when PWM signal is below 6%.

Three-Phase Six-Pole Drive Motor
Greater output power and torque. Fully utilizes electrical energy, reducing energy loss.
Better starting performance. Capable of quick start-up and reaching rated speed, improving operational efficiency.
Less noise and vibration. Reduces mechanical friction and electromagnetic interference, decreasing noise and vibration.
Precise PWM closed-loop design. Designed with speed compensation function, unaffected by air resistance, enhancing heat dissipation efficiency.

Metal Shaft
Enhances structural strength.
Improves reliability and durability.
Superior dynamic balance.

Neodymium Magnet
A strong neodymium magnet is placed at the bottom of the fan frame, perpendicular to the shaft. This magnetic structure effectively mitigates displacement due to centrifugal force during high-speed operation, thereby reducing fan vibration and ensuring more stable fan operation.

Dustproof Design
Dust-proof structure encloses the internal drive components, preventing entrance of dust or debris corroding electronic components inside, thus extending the lifespan of the fan.

Exterior Geometric Ribs
Overall structural enhancement strengthens the fan frame rigidity and reduces resonance.
