Compact 40 mm Cooling Fan

The OEM Industries MW-410H05C is a 40 mm by 10 mm axial fan built for tight spaces such as notebook chassis, small-form-factor desktops or embedded systems. It runs on a 5 V supply drawing 0.22 A through a two-pin connector and uses a ball-bearing motor for reliable rotation. The black frame and blade assembly contain no lighting.

Suited for Low-Power Thermal Slots

This unit suits repair technicians and system integrators who need a direct replacement for a 40 mm two-pin fan in legacy laptops, thin clients or industrial boards. Builders requiring higher airflow, PWM speed control, a three- or four-pin header or larger frame dimensions should look at alternative cooling solutions.

5 V Two-Pin Power Interface

The cooler connects via a standard two-pin header delivering 5 V at 0.22 A, so the target device must provide that exact voltage and connector layout. Verify the header pinout and available mounting holes before installation to ensure mechanical and electrical compatibility.

Questions about this item

How do I connect the 2-pin plug to a 5V header without reversing polarity?

Align the two wires with the 5V and ground pins on the header; the connector only fits one way, so press it straight down until seated.

When will the ball bearing need replacement?

The ball bearing is rated for continuous operation; expect to replace the fan when noise or vibration increases after extended use.

What thermal limit appears first during sustained load on this 40mm cooler?

The 5V 0.22A motor reaches its maximum airflow ceiling before the heatsink saturates, so temperatures rise once the fan hits peak RPM.
