40mm 12V Ball Bearing Fan

The OEM Industries AD0412MB-G76 is a compact 40mm square cooling fan designed for 12 volt DC operation. It uses a ball bearing for durability and connects via a standard 3 pin power connector. No LED lighting is included. The unit measures 40 by 10 millimetres and draws 0.08 amps.

Suits Tight Spots and Legacy Headers

This fan fits builds that need a 4010 form factor and a three pin header for speed monitoring. It is not for buyers who want a larger frame size, a four pin PWM connector, or integrated RGB illumination. Systems requiring higher airflow or a different voltage should look at something else.

3 Pin 12V Connector Decides Fit

The power connector is a three pin 12V type, so the motherboard or controller must provide a matching header. If the board only offers four pin PWM or a different voltage rail, this cooler will not connect correctly. Confirm the header type before ordering.

Questions about this item

How often should the ball bearing in this AD0412MB-G76 fan be relubricated or replaced?

The ball bearing is sealed for the fan's service life; no relubrication is required and replacement is only needed if the bearing becomes noisy or seizes.

What thermal or current limit appears first when the 12 V 0.08 A motor runs continuously?

The 0.08 A current draw at 12 V defines the steady-state limit; the motor will not exceed this draw as long as voltage stays at 12 V.

How much heat and noise does the 40 mm frame produce during all-day operation?

At 12 V the fan spins at its rated speed, moving air quietly for a 40 mm frame while dissipating only the heat from its 0.08 A draw.
