Delta AFB1212HHE-PWM 120x38mm Dual Ball Bearing High Speed Fan, 4Pin PWM

Smart fan speed control via PWM connection, so you have more cooling when system is working hard and more quietness when system is under less load.

RMP vs. Duty Cycle: 0 RPM at 0% duty cycle, 600 RPM at 20% duty cycle, 1350 RPM at 50% duty cycle, 2100 RPM at 75% duty cycle, 2900 RPM at 100% duty cycle.

Locked Rotor Protection where impedance of motor winding protects motor from fire in 96 hours of locked rotor condition at the rated voltage.

Over Current Protection will shut down the current when rotor is locked. Polarity Protection is activated when reverse connection happens with positive and negative leads.
