OEM Industries 40mm 3-Pin Fan

The OEM Industries 1608KL-04W-B79 is a 40mm square cooling fan that runs on 12V at 0.25A through a standard 3-pin power connector. It is sold new as a fan-only unit in a black finish. The component is built by NMB and matches the 4020 form factor for direct replacement or custom cooling projects.

Suits tight 40mm mounts; not for larger bays

This fan fits systems that require a 40mm by 20mm frame with three-wire speed reporting. Builders needing a compact DC cooler for industrial enclosures, small-form-factor boards or legacy CPU air coolers can use it. Buyers who need a larger frame size, PWM control or integrated lighting should look at something else.

3-pin 12V 0.25A power specification

The single specification that decides compatibility is the 3-pin 12V 0.25A power interface. The motherboard or fan controller must supply 12 volts and accept a three-wire connection for tachometer feedback. If the header provides only two pins or a different voltage, this fan will not operate correctly.

Questions about this item

Does the 1608KL-04W-B79 include mounting screws or just the 40mm fan?

The listing describes a fan-only unit, so only the 40mm square cooler with its 3-pin connector is supplied; mounting hardware is not included.

The title mentions 4020 — does that mean 40mm by 20mm thick?

Yes, the 4020 designation indicates a 40mm square frame that is 20mm deep, matching the 1608KL-04W-B79 dimensions.

What airflow can I expect from the 12V 0.25A rating in a live system?

At 12V and 0.25A the fan draws 3W, which typically yields modest airflow suited to low-profile heatsinks or tight chassis spots rather than high-performance cooling.
