Compact 5 V blower for tight enclosures

The OEM Industries EFWF-03F05L is a DC brushless blower that runs on a 5 V supply and draws 0.15 A through a 3-pin connector. Its two-tone housing contains both the fan and heatsink elements in a single assembly designed for confined spaces such as projectors or notebooks. No LED lighting is fitted.

Suits low-voltage 3-pin headers only

This cooler fits devices that provide a 5 V 3-pin header and need a blower-style airflow path. It is not for builds that require a 4-pin PWM connection, a higher voltage rail or a larger heatsink mass. Buyers needing adjustable speed control or greater thermal capacity should look elsewhere.

5 V 0.15 A 3-pin power specification

The single deciding specification is the 5 V 0.15 A 3-pin power requirement; the cooler will only operate correctly when the host supplies exactly that voltage and connector type.

Questions about this item

Will the 3-pin 5 V 0.15 A blower plug directly into an older motherboard header that only supplies 5 V?

The cooler uses a standard 3-pin connector rated for 5 V at 0.15 A, so it will draw power from any 5 V fan header without an adapter.

How can I confirm the EFWF-03F05L is spinning correctly once installed?

Enter the BIOS or use monitoring software to verify the fan reports an RPM reading and that the 3-pin signal wire is active.

Does the package include mounting hardware for a notebook heatsink or must I source brackets separately?

Only the blower unit with its 3-wire lead is supplied; any retention brackets or thermal interface material must be purchased separately.
