Zyvpee 1608KL-05W-B39 T00 40*20MM DC24V 0.08A 3 Pin case fan

Compact 40 mm cooling fan

The Zyvpee 1608KL-05W-B39 is a 40*20 mm DC24V case fan drawing 0.08A. It uses a three-pin power connector and ball bearing construction. The non-LED black frame suits industrial IPC enclosures and small-form-factor builds that need a 4020 footprint.

Fits tight 4020 mounting points

This unit slots into standard 40 mm square cut-outs with a 20 mm depth allowance. The three-wire lead connects directly to a 3-pin header for tachometer feedback. Ball bearing operation reduces maintenance in continuous-duty inverter cooling roles where sleeve bearings would wear faster.

Replaces worn 40 mm ball-bearing fans

When an existing 4020 fan develops noise or vibration, this model restores original airflow without modifying the chassis. The jump is worth it if the original unit lacks a tachometer wire or uses a sleeve bearing that has seized. Buyers needing PWM speed control or larger frame sizes should look elsewhere.
