OEM MF40K-09 40mm Fan

The OEM Industries MF40K-09 is a 40mm micro fan built for compact cooling tasks. It runs on a 9V supply drawing 0.06A through a two-pin connector. The black frame houses a ball bearing for durable rotation. This unit is sold as a fan only, without a heatsink or mounting hardware.

Suits tight-chassis spot cooling

This fan fits builders who need a 40mm replacement for routers, switches or small-form-factor boards that accept a two-pin 9V header. It will not serve anyone who requires a full CPU cooler with heatsink, PWM control or a larger airflow envelope. Buyers needing higher static pressure or a four-pin header should look elsewhere.

9V two-pin power input

The decisive specification is the 9V 0.06A two-pin power requirement. Verify that the target device provides exactly this voltage and connector before purchase. A mismatched header or voltage will prevent operation or damage the fan.

Questions about this item

What comes in the box with the MF40K-09 and is any extra cable or mount needed?

The package contains the 40 mm ball-bearing fan with its 2-pin lead attached. No separate power cable, mounting screws or bracket are included.

The MF40K-09 is listed at 9 V and 0.06 A — which version should I pick for a 9 V header?

This model is a single 9 V 0.06 A variant; choose it when your board or device provides a 9 V two-pin header.

What does the 9 V 0.06 A rating mean once the fan is installed in a router or switch?

It draws 0.06 A from a 9 V supply, giving a low-power airflow suitable for small chassis cooling.
