Questions about this item
Will the sleeve bearings in these 4020 fans need lubrication or replacement after continuous server use?
Sleeve-bearing fans of this size and voltage will eventually develop bearing noise or wear; plan to replace any unit that becomes audible or spins irregularly.
What limit appears first when these 12 V 0.40 W fans run continuously in an inverter enclosure?
The 0.40 W motor reaches its thermal ceiling before airflow drops, so sustained operation is bounded by motor temperature rather than static pressure.
