40 mm Ball-Bearing Cooling Fan

The OEM Industries PL40B12HH-1 is a 40 mm square DC fan designed for tight spaces inside a chassis or on a small-form-factor CPU cooler. It runs on 12 V power and draws 0.12 A through a two-wire lead. The ball bearing construction targets longer life in continuous operation. Buyers who need PWM speed control or a larger airflow envelope should look elsewhere.

Simple Two-Wire Installation

Connect the red and black leads directly to a 12 V fan header or a compatible molex adapter; no PWM pin is present so the fan will run at full speed whenever powered. The compact 4010 frame fits standard 40 mm mounting holes, but the shallow 10 mm depth can interfere with recessed headers or tall memory modules if clearance is not checked first. Vibration may transfer to thin sheet metal unless rubber grommets are used.

Fixed-Speed 12 V Operation

Because the unit lacks a third wire for pulse-width modulation, the motherboard cannot regulate its RPM based on temperature. The 0.12 A draw is modest, yet the constant 12 V feed means acoustic output stays the same under idle and load. Builders who rely on fan curves or software-controlled quiet modes will not be able to use those features with this model.
