Compact 40mm case fan

This 40mm square fan measures 40 by 40 by 20 millimetres and carries the 1608KL-05W-B39 designation. It runs on 24 volts and draws 0.08 amps. The unit is supplied new and matches the 4020 form factor used in Fanuc heatsink assemblies.

For tight-space cooling replacements

Builders fitting a direct replacement into a Fanuc heatsink or similar 4020 mounting will find the correct voltage and dimensions here. Buyers who need a different voltage, a larger frame, or higher airflow for a standard PC chassis should look at other models.

Questions about this item

How do I install the 40x40x20mm fan and what step is often missed?

Mount the 4020 frame using the four 40 mm screw holes, then connect the two-wire lead to a 24 V header; the step most often missed is checking airflow direction so the fan blows toward the heatsink instead of away from it.

What maintenance will the 1608KL-05W-B39 need later?

Expect to clean dust from the blades and vents every few months; if bearing noise appears or the 0.08 A draw rises, replace the entire 24 V unit as bearings are not serviceable.
