Compact 40 mm Sleeve Fan for Tight Chassis

The OEM Industries KF0420S5H-R is a 40 mm square fan only 20 mm thick that runs on 5 V and draws 1.3 W through a two-pin connector. Its sleeve bearing keeps the profile low while moving air through notebook coolers, small-form-factor cases or embedded enclosures where larger fans will not fit.

Replaces Noisy or Failed Stock 4020 Fans

Swap this unit in when an original 4020 cooler becomes loud, develops bearing rattle or stops spinning. The direct 5 V two-wire interface matches most legacy laptop and industrial boards, so the upgrade is worthwhile whenever the existing fan shares the same voltage, connector and mounting holes.

Suits Repair Technicians and SFF Builders

Technicians servicing thin laptops, 1U servers or custom electronics will appreciate the exact 40 mm by 20 mm footprint and black sleeve-bearing design. Builders who need PWM speed control, higher static pressure or a larger frame should look at other cooling options because this model provides only fixed-speed two-pin operation.

Questions sur cet article

Will the 40 mm by 20 mm frame fit my laptop's fan slot?

The fan measures 40 mm square and 20 mm thick, so it fits any opening that accepts a standard 4020 form factor.

How do I connect the two-pin power lead correctly?

Plug the 2-pin connector onto a 5 V header matching the 1.3 W draw; reversing the wires will prevent the fan from spinning.

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

Sleeve bearings typically last several years at 5 V; replace the unit once audible rumble or reduced airflow appears.
