Compact blower for tight builds

The OEM Industries AB5012HB-C03 is a 50mm centrifugal blower designed for confined chassis where axial airflow cannot reach the heatsink. It suits small-form-factor PCs, industrial appliances and projector units that demand directed exhaust through a narrow duct.

Sustained operation with ball bearing

Ball-bearing construction keeps rotational stability consistent during continuous duty cycles rather than only at startup. The 12V 0.21A draw remains steady so thermal output does not drift when the load persists for hours.

Verify voltage and header before fitting

Confirm the target device supplies 12V on a three-pin header and that the 50x20mm footprint clears surrounding components. The three-wire lead provides tach feedback but no PWM control, so speed regulation depends on the host voltage. Buyers needing PWM or a larger frame should look elsewhere.

Questions about this item

How much noise and heat does the 50mm ball-bearing blower produce when running continuously at 12V 0.21A?

The fan draws 0.21 A at 12 V through its 3-pin connector and uses a ball bearing, so sustained operation stays within that electrical envelope without extra friction heat.

What motherboard header or controller do I need to connect the 3-pin power connector?

A standard 3-pin fan header supplying 12 V is required; the lead has three wires for power, ground and tachometer signal.

Will the 50x20mm centrifugal blower fit in the same mounting holes as my older 50mm axial fan?

The blower measures 50 mm square by 20 mm thick, so it only fits brackets designed for that exact footprint and blower-style airflow direction.
