Zyvpee 4715KL-07W-B39 P09 120mm 38mm 48V 3 Pin case fan

48 V 3-pin case fan

The Zyvpee 4715KL-07W-B39 P09 is a 120 mm by 38 mm DC square cooler built around an NMB motor with ball bearings. It draws 0.21 A at 48 V through a standard three-wire connector and ships without any LED lighting. The unit targets servers or workstations that require a high-voltage airflow solution in a compact 12038 frame.

Ball bearing thermals at 48 V

Ball bearings keep friction low while the 48 V supply delivers steady torque for consistent airflow. The three-pin header reports speed to the motherboard so the system can balance cooling against acoustic output. With no RGB or PWM circuitry the electrical load stays minimal during normal operation.

Sustained load in a 12038 frame

Under continuous duty the thicker 38 mm profile moves more air than slim alternatives without increasing the 120 mm footprint. The ball bearing design resists wear when the fan runs at constant speed for extended periods. Builders needing 12 V or PWM control should look elsewhere because this model is fixed at 48 V DC only.
