OEM Industries SCBD12X4S-304 120mm 32mm 3 Pin centrifugal cooler

Centrifugal Blower for Tight Chassis

The OEM Industries SCBD12X4S-304 is a 120 mm centrifugal blower designed for cases where a conventional axial fan cannot exhaust heat directly. Its 32 mm thick frame houses a 12 V, 0.2 A motor rated at 2.4 W, making it suitable for compact industrial enclosures or small-form-factor PCs that need focused airflow through restricted vents.

Steady Airflow Through Restrictions

Because the impeller pushes air outward across a 12032 profile, the blower maintains pressure when ducts, filters or dense heatsink fins resist flow. Ball bearings support continuous duty at the rated 12 V input, so the 3-pin connector delivers consistent speed without the voltage sag that can stall weaker axial fans in the same space.

Verify Mounting And Power Before Ordering

Confirm your chassis has 120 mm mounting points spaced for a 32 mm deep housing and that the 3-pin header on your board or controller supplies 12 V. The two-tone finish is cosmetic only; the unit includes no LEDs or PWM control, so speed will vary with voltage rather than a fourth wire signal.
