Compact 40 mm Server Fan

The OEM Industries MMF-04C12DS is a 40 mm by 15 mm axial fan built for tight server and inverter enclosures. It runs on 12 V DC drawing 0.14 A through a two-wire connection and uses a ball bearing for continuous operation. The black frame and blades suit industrial chassis where space is at a premium.

Suited For

This unit fits technicians maintaining ABB drives, Fanuc controllers or similar 4 cm cooling slots that require a straightforward 12 V replacement. It is not for builders who need PWM speed control or a tachometer signal for motherboard monitoring. Buyers wanting RGB lighting or larger airflow volumes should look elsewhere.

Two-Wire 12 V Power Interface

The only electrical interface is a two-wire 12 V feed delivering 0.14 A, so the fan runs at full speed whenever power is applied. Verify that your equipment accepts a two-wire 4015 form factor before ordering.

Questions about this item

What does the 0.14 A current draw mean for my 12 V fan header?

The fan draws 0.14 A at 12 V, so it will not overload a standard motherboard header rated for 1 A or more.

How does the two-wire connection affect speed control?

With only power and ground wires, the fan runs at full speed constantly; voltage regulation is the only way to change RPM.

Will the 40 mm by 15 mm frame fit my server chassis slot?

The unit measures 40 mm square and 15 mm thick, matching the common 4015 form factor used in many 1U servers.
