Compact 24 V 40 mm case fan

This 40×40×20 mm DC fan runs on 24 V and draws 1.54 W. It is built for inverter recorder cooling and similar tight spaces where a 4020 frame is required. The unit is supplied new as a single piece.

Direct 4020 frame replacement

It replaces an existing 4020 fan that uses the same 24 V supply and mounting pattern. The upgrade is worthwhile when the original fan has failed or noise has become excessive. It is not suited for builds that need higher airflow or a different voltage.

Questions about this item

What are the exact mounting-hole dimensions for the 40 mm square frame?

The frame measures 40×40×20 mm with standard 40 mm fan mounting spacing, so it fits any 40 mm fan cut-out or bracket.

How do I connect the 24 V DC leads without damaging the inverter recorder?

Match the red wire to +24 V and the black wire to ground on the recorder’s fan header; reverse polarity will stop the fan but will not harm the motor.
