120mm Square Cooling Fan

The OEM Industries CHB12012DS-A is a 120mm square cooling fan designed for CPU air cooler builds. It suits system integrators and DIY builders who need a straightforward replacement or case airflow upgrade. The unit ships new in black and operates on a standard 12V supply.

Capacity and headroom: 0.47A draw

At 12V the fan draws 0.47A, giving modest airflow for low-to-mid thermal loads such as office CPUs or entry-level gaming chips. It lacks the static pressure headroom for dense radiator fins or heavy overclocks, so high-TDP workstations will need a stronger solution.

Build quality and connectors

Ball-bearing construction reduces friction and extends service life compared with sleeve alternatives. The 3-pin power connector delivers fixed-voltage operation without PWM control, meaning speed stays constant unless the motherboard varies voltage. No LED lighting keeps the profile clean for non-windowed cases.

Questions about this item

Will the 3-pin connector on this CHB12012DS-A fan plug directly into a legacy motherboard header without an adapter?

Yes, the fan uses a standard 3-pin power connector that fits older 3-pin CPU or chassis fan headers directly.

How can I confirm the ball-bearing fan is spinning at the correct speed after installation?

Enter the BIOS or use monitoring software to check the RPM reading reported by the 3-pin header; a steady value indicates the tachometer signal is working.

Does the box include mounting screws for a 120 mm fan frame or do I need to supply my own?

The product is supplied as a fan only; mounting screws for the 120 mm square frame are not included and must be sourced separately.
