Compact 38 mm Ball-Bearing Fan

The OEM Industries F3828B12HB is a 38 mm square axial fan with a 28 mm frame depth. It runs on 12 V DC at 0.3 A and uses a three-pin power connector. The ball-bearing design suits continuous operation in tight chassis locations.

Suits Space-Constrained Cooling Slots

This fan fits 38 mm mounting holes where larger coolers cannot be installed. Builders needing higher airflow, PWM speed control or integrated LED lighting should look at other models.

Check Mounting Pattern and Header Type

Verify that your board or device provides a three-pin 12 V header and the standard 32 mm hole spacing. The fan has no PWM wire, so speed control depends on voltage regulation from the header.

Questions about this item

What power connector does the 38 mm F3828B12HB fan use?

It connects via a standard 3-pin header, so the motherboard or fan controller must provide a matching 3-pin socket.

Can the 12 V 0.3 A ball-bearing fan replace a noisier sleeve-bearing unit of the same 38 mm frame?

Yes, the ball bearing design fits the identical 38 mm mounting pattern and draws the same 12 V 0.3 A, offering longer life and consistent speed.

How can I verify the F3828B12HB is spinning correctly after installation?

Check the BIOS or monitoring software for a stable RPM reading on the 3-pin header; the fan should report speed without PWM control.
