Compact 40 mm case fan for tight builds

This AVC Original DBTA0420B2H 4020 measures 40 by 40 by 20 mm and runs on 12 V at 0.38 A. It suits small-form-factor chassis or GPU coolers that need a thin 4 cm frame. Buyers who need higher airflow or larger mounting holes should look elsewhere.

Check 12 V header and 40 mm mounting before ordering

Verify your board or controller has a free 12 V fan header and that the case or heatsink offers 40 mm screw spacing. The 20 mm thickness must clear nearby components and side panels. Confirm the connector type matches your header pin layout.

Questions about this item

What comes in the box with the DBTA0420B2H 4020 fan and do I need a separate power cable?

The package contains the 40 mm × 40 mm × 20 mm case fan only; it connects directly to a standard 12 V fan header so no extra power cable is required.

Should I choose the .38 A model or a different current rating for my build?

This unit draws .38 A at 12 V; select it when your fan header or controller is rated for at least that current, otherwise look for a lower-amperage model.
