Compact 40 mm inverter cooling fan

The Zyvpee 1608KL-05W-B59 is a 40x20 mm DC 24 V case fan rated at 0.11 A. It uses a three-pin power connector and ball bearing for reliable airflow in tight chassis spaces. The non-LED black frame suits industrial or embedded builds where indicator lights are unwanted.

Verify voltage and connector compatibility

Ensure your system provides a 24 V DC supply and a matching three-pin header before ordering. The physical footprint is 40 by 20 mm, so confirm the mounting holes and clearance in your enclosure. No PWM control is present, so speed regulation depends on the host circuit.

Replaces 40 mm two-wire or sleeve-bearing units

This fan upgrades older 4020-size fans that lack a tachometer wire or use less durable sleeve bearings. The ball bearing and third wire add speed monitoring and longer service life. The jump is worth it when maintenance access is difficult or continuous inverter cooling is critical.

Questions about this item

Does the 40×20 mm case fan come with mounting screws or do I need to buy them separately?

The package contains the fan unit only; standard 40 mm mounting screws are not included and must be sourced separately.

The title lists 4020 and the model is 1608KL-05W-B59 — are these different versions or the same fan?

Both refer to the identical 40×20 mm DC 24 V ball-bearing fan; 4020 is the size shorthand and 1608KL-05W-B59 is the manufacturer model code.

With a 0.11 A draw at 24 V, what does that mean for airflow inside a typical chassis?

The low 0.11 A current indicates modest airflow suited to spot-cooling small enclosures or inverter modules rather than high-volume case ventilation.
