Product identity

The OEM Industries XFAN 12038 RGM1238B1 is a 120mm by 38mm DC brushless fan rated at 12V and 2.0A. It uses a four-pin connector for PWM control and is sold as a fan-only unit in black. The 2-ball bearing design targets builders who need a high-airflow cooler for dense heatsinks or radiators.

Compatibility checks

Verify that your case or heatsink has mounting holes for a 120mm frame and can accommodate the 38mm thickness. Ensure the motherboard or fan controller provides a standard four-pin header capable of supplying the rated 2.0A current. Confirm there is enough clearance around the mounting area for the deeper profile before ordering.

Thermals, noise and power

The fan draws up to 2.0A at 12V, so power delivery must match that load. As a raw frame without shroud or ducting, acoustic output will depend heavily on the heatsink or radiator it is paired with and the PWM curve configured in BIOS or software. The 2-ball bearing is chosen for durability under continuous high-speed operation.

Questions about this item

Does the XFAN 12038 RGM1238B1 ship with mounting hardware or is it just the 120 mm fan?

The listing specifies "Type: Fan only", so you receive the 120 mm by 38 mm 4-pin unit alone; brackets, screws or thermal paste must be sourced separately.

Should I pick the 2.0 A model or a lower-amperage version for a standard 4-pin header?

The RGM1238B1 draws 2.0 A at 12 V; most motherboard headers are rated for 1 A, so a dedicated fan controller or hub is advisable rather than a direct header connection.

What does the 2.0 A rating mean for airflow and noise once the fan is installed?

At 2.0 A the motor can spin the 12038 frame at high RPM for strong static pressure, but expect audible noise at full speed; PWM control via the 4-pin wire lets you balance cooling and acoustics.
