I have a Meanwell style Chinese power supply that has a thermal switch to control the fan.
Thing is, the thermal switch is just tucked into the output inductor.
Meanwell themselves seem to have their sensor on the pcb and using some kind of solid sliastic type material to 'glue' it to the inductor. (not a thermal epoxy, it is just that hard type silastic compound)
This particular supply seems well put together, and not your typical cheap Chinese supply, even using quality caps... so this was the one thing that seemed, odd.
Is this the right place to put such a thermal switch. or would it be better mounted to the case?
Is this typical? I am used to seeing thermal switches or sensors on the heat sink. though the heat sink here would be the case itself.
