TSUJ 2-in-1 accessory for inverter cooling

This TSUJ accessory integrates a DC12V 0.10A EFB0412MD 4020 4cm 2-wire double ball bearing fan designed for inverter cooling. It fits 2-in-1 laptop systems requiring targeted airflow in a compact form factor. The part number Kepler-C72J-OYS-0221 identifies the unit for service and replacement. New condition ensures reliable operation from first install.

Capacity and headroom for inverter thermal loads

The fan draws 0.10A at 12V, delivering steady airflow for moderate inverter heat loads. Double ball bearing construction supports continuous duty cycles without early wear. It handles typical inverter cooling demands but may reach limits under sustained peak thermal output. Buyers needing higher airflow or larger frame sizes should verify specifications before purchase.

Questions about this item

Will the 12V 0.10A fan connect to the same header I used for my old 4020 cooler?

Yes, the 2-wire plug fits standard 12V headers; match the red and black leads to the board markings and the double ball bearing motor will start at 0.10A.

How can I confirm the EFB0412MD is spinning correctly once installed?

Power the system, listen for the smooth double ball bearing whir, feel airflow from the 4cm frame, and verify the tachometer reports a steady RPM in BIOS or monitoring software.
