120 mm DC brushless cooler

The OEM Industries AQ1212HB-F51 is a 120 mm by 38 mm DC brushless fan rated for 12 V and 0.5 A. It uses a two-wire power connector and a dual-ball bearing for continuous operation in server chassis or workstation enclosures.

Suited for 12 V two-wire headers

This cooler fits builds that require a 120 mm fan with a standard two-wire connection and 0.5 A current draw. It is not intended for systems that need PWM speed control, three- or four-pin headers, integrated LED lighting, or a heatsink assembly bundled with the fan.

Verify header and clearance

Confirm the motherboard or fan controller provides a 12 V two-pin header rated for at least 0.5 A. Ensure the 38 mm thickness clears surrounding components and that the mounting holes match a 120 mm pattern before ordering.

Questions about this item

Will the 12 V, 0.5 A rating let me run this fan from a standard motherboard CPU fan header?

Yes, the fan draws 0.5 A at 12 V, which is within the typical 1 A limit of most motherboard CPU fan headers.

Can I use the existing two-wire power lead from my old 120 mm fan to connect this AQ1212HB-F51?

Yes, this cooler uses a two-wire power connector, so it will plug directly into the same two-wire header or adapter you already have.

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

Power the system, enter the BIOS hardware monitor or use a monitoring utility, and verify the CPU fan RPM reads a steady value above zero.
