Compact 40 mm notebook fan

The OEM Industries CF-05407S is a 40 mm square fan built for tight notebook and small-form-factor chassis. It draws 0.18 A at 5 V through a two-pin connector and uses a sleeve bearing for quiet operation. No LED lighting is included.

5 V 0.18 A power envelope

At 5 V and 0.18 A the fan delivers modest airflow suited to low-TDP processors or auxiliary cooling spots. It cannot sustain high static pressure, so it runs out of headroom on sustained heavy loads or in poorly ventilated enclosures.

Two-pin simplicity

The two-pin lead provides power only, meaning speed control depends on the host board's voltage regulation. No PWM signal wire is present, so automatic fan curves are not supported. The bundle contains only the fan unit itself.

Questions about this item

Will the 40 mm frame and 7 mm thickness fit the mounting holes on my older notebook heatsink?

The fan measures 40 mm square and 7 mm thick, matching the CF-05407S form factor used in many legacy notebook coolers; verify your heatsink screw spacing before installing.

How can I confirm the 5 V 0.18 A sleeve-bearing fan is spinning correctly after I connect the 2-pin header?

Power the system and listen for smooth rotation; the 2-pin connector supplies 5 V at 0.18 A, so the fan should start immediately and run without rattling from the sleeve bearing.

Does the package include only the bare 40 mm fan or are mounting screws and a heatsink also supplied?

The item is listed as fan only — a black 40 mm sleeve-bearing unit with 2-pin cable — so you will need to reuse or source screws and any heatsink separately.
