OEM Industries MFB30E-12A 30mm 12V 0.03A 3 Pin Fan

Compact 30 mm cooling fan

The OEM Industries MFB30E-12A is a 30 mm square micro fan built for tight spaces such as Raspberry Pi enclosures or small-form-factor CPU coolers. It runs on 12 V and draws 0.03 A through a standard three-pin connector. The black frame and ball bearing suit embedded and DIY projects where a low-profile airflow source is required.

Steady low-power airflow

At the rated voltage the fan delivers continuous airflow without the current spikes seen in larger PWM units. The ball bearing maintains consistent speed during extended operation, making it suitable for always-on devices that cannot tolerate bearing noise or sudden stalls. Its modest power draw keeps thermal contribution minimal inside sealed cases.

Drop-in replacement for 30 mm two-wire fans

This unit replaces older 30 mm two-wire fans that lack speed reporting, adding a tachometer line for monitoring. The upgrade is worthwhile when the host board supports three-pin headers and the builder needs RPM feedback for fan-curve control. It does not suit builds requiring PWM speed regulation or higher static pressure.
