120 mm dual-ball fan

The OEM Industries DATA1238B2H is a 120 mm cooling fan built with a dual-ball bearing for extended service life. It connects via a standard 3-pin power connector and operates without LED illumination. The unit is supplied new as a fan-only component for system integrators and PC builders.

12 V 1.04 A power envelope

The fan draws 1.04 A at 12 V, providing a fixed airflow ceiling suited to moderate thermal loads. It handles typical CPU cooler duties but runs out of headroom when tasked with high-static-pressure radiators or densely finned heatsinks that demand greater flow. The 38 mm frame depth adds mass but does not alter the electrical limit.

Three-wire speed reporting

The 3-pin interface supplies power and a tachometer signal for RPM monitoring, but lacks PWM control. Motherboard headers can only vary voltage to change speed, so precise low-RPM tuning is not possible. Builders needing closed-loop fan curves or 4-pin PWM headers will find this interface insufficient.

Questions about this item

Will the 120mm 3-pin connector work on my older motherboard that only has 3-pin headers?

Yes, the 3-pin connector fits standard 3-pin motherboard headers and runs at 12V 1.04A.

How can I confirm the 2-ball bearing fan is spinning correctly after installation?

Check the BIOS hardware monitor or software utility for RPM readings; the 3-pin wire provides a tachometer signal.

Does the box include mounting screws or a 4-pin adapter for the DATA1238B2H?

The unit is a fan only; screws and any 4-pin adapters must be purchased separately.
