4 cm 2-Wire Chassis Fan for Compact Systems

This 40 mm two-wire cooling fan operates at 12 V and draws 0.18 A, delivering high airflow in a small frame. It is designed for tight enclosures such as 2-in-1 laptops, mini PCs or embedded boards where space is limited.

Airflow capacity and thermal limits

The fan moves a large volume of air for its size, keeping components cool under moderate loads. It will not sustain heavy continuous heat output from high-wattage CPUs or GPUs, so builders needing greater thermal headroom should consider larger or additional cooling.

Questions about this item

Will the 12 V 0.18 A fan run safely from the same 12 V header that powered my old 4020 model?

Yes, the 12 V 0.18 A rating matches a standard 12 V header, so it will draw the expected current without overloading the connector.

How can I confirm the 4020 fan is moving air correctly after I install it?

Power the system, listen for steady rotation, and hold a light tissue near the exhaust — it should be drawn firmly toward the grille.
