Compact 40 mm cooling for tight builds

This 4020 case fan runs on 12 V and draws 0.18 A, making it suitable for small-form-factor chassis or industrial enclosures where space is limited. The double-ball bearing design targets longer service life under continuous operation.

Simple two or three-wire connection

Installation requires matching the 2-wire or 3-wire lead to a standard 12 V header; polarity must be observed to avoid damage. The 40 mm frame leaves no room for error in cramped mounts, so verify clearance before ordering.

Questions about this item

How can I confirm the 12V 0.18A fan is spinning correctly after connecting it?

Check that the blades rotate smoothly and listen for quiet operation from the double-ball bearings.

Does the package include both 2-wire and 3-wire connectors or must I buy an adapter separately?

The fan supports both 2-wire and 3-wire connections so no extra adapter is required for standard headers.
