OEM Industries AD0412MB-C53 40x20mm 3 Pin Fan

Compact 40 mm case fan

The AD0412MB-C53 is a 40 mm square cooler from ADDA designed for tight chassis spaces. It runs on 12 V and draws 0.13 A through a standard three-pin connector. No LED lighting is fitted, keeping the unit suitable for inconspicuous builds. The ball bearing supports continuous operation in industrial or embedded environments.

Ball bearing thermals and acoustics

The ball bearing reduces friction compared with sleeve alternatives, helping the fan maintain steady airflow at its rated voltage. Power consumption stays at the specified 0.13 A, so the load on a motherboard header or fan controller remains minimal. Noise output is limited to the mechanical sound of the bearing and airflow through the 40 mm frame. No speed-control circuitry is integrated beyond the three-pin voltage interface.

Three-pin integration and clearance

The three-pin plug connects directly to standard motherboard or controller headers without adapters. Its 40 mm by 20 mm footprint frees surrounding space for dense component layouts or narrow ducting. Builders needing higher static pressure or larger airflow volumes will require a bigger frame size. The lack of PWM means speed regulation depends on voltage adjustment rather than a fourth wire.
