OEM Industries C5010B12MV 50mm 12V 0.15A 3-wire CPU cooler

Compact 50 mm square cooler

The OEM Industries C5010B12MV is a 50 mm square fan-only cooler designed for tight spaces where a low-profile air mover is required. It runs on 12 V at 0.15 A and connects through a standard three-pin header, making it a straightforward drop-in for small-form-factor builds or replacement of an existing 5010 unit. The ball bearing and black finish complete the basic specification.

Ball bearing sustains steady airflow

Under continuous load the ball bearing maintains consistent rotation without the friction increase that sleeve designs develop over time. The 12 V 0.15 A draw keeps power demand modest while the three-pin connection allows the motherboard to monitor speed and adjust voltage as temperatures rise. This combination delivers reliable airflow for extended periods in compact enclosures.

Three-pin header limits control granularity

The three-wire interface provides tachometer feedback but lacks the fourth PWM wire, so voltage regulation is the only speed-control method available. Motherboards that only support PWM duty-cycle control may not reduce the fan below its minimum start voltage, limiting acoustic optimisation at idle. Builders needing finer low-speed control should verify their board offers voltage-based fan curves.
