Compact 40 mm fan for tight spaces

The OEM Industries AD0405HB-C50 is a 40 x 20 mm square cooler that runs on 5 V at 0.29 A. Its two-wire connection and ball bearing suit small-form-factor builds, embedded boards or replacement cooling where a low-profile axial fan is required.

Replaces worn 40 mm two-wire fans

This unit fits the same footprint as legacy 4020 coolers that have become noisy or seized. The jump is worth it when the original sleeve-bearing fan fails or when a 5 V header is the only power source available on the board.

Mounts directly to 40 mm screw holes

The black frame aligns with standard 40 mm mounting points and needs no adapter brackets. It frees up vertical clearance in 1U or slim enclosures while drawing minimal current from a 5 V rail.

Questions sur cet article

Will the 40x20mm AD0405HB-C50 fit my case fan mounts?

The fan measures 40x20mm; check that your chassis or heatsink has mounting holes for a 40mm square frame of that thickness.

How do I connect the two-wire 5V 0.29A lead correctly?

Plug the two-wire connector into a 5V fan header observing polarity; the common mistake is reversing the wires, which prevents the fan from spinning.

When should I plan to replace the ball-bearing fan?

Ball bearings typically run for tens of thousands of hours; replace the unit if noise increases or rotation becomes uneven.
