OEM Industries CL-5020L-01 50mm 12V 150mA 3-pin blower CPU cooler

Compact 50mm Blower Fan

The OEM Industries CL-5020L-01 is a 50mm by 20mm DC brushless blower designed for tight spaces such as projectors and small-form-factor systems. It operates on 12V at 150mA and uses a 3-pin power connector. The unit is supplied as a fan only without LED lighting. Its two-ball bearing supports continuous operation in constrained environments.

3-Pin Integration

The three-wire connection provides power and a tachometer signal so the host board can monitor speed. Because the frame measures 50mm by 20mm it fits where larger axial fans cannot, freeing surrounding clearance for other components. No additional mounting hardware is included so builders must provide their own brackets or screws. The blower layout directs airflow through a focused outlet rather than across a broad surface.

Thermal and Acoustic Profile

The two-ball bearing reduces friction compared with sleeve designs, helping to keep operational noise steady over time. At the rated 12V input the current draw remains at 150mA, limiting power demand on the system supply. The blower format moves air through restricted channels, making it suited for directed cooling rather than case-wide ventilation. No PWM control is present so speed varies only with voltage changes.
