Questions about this item

Will the 65 W output sustain a full load continuously without overheating?

The adapter is rated for 65 W at 18.5 V and 3.5 A with a 100–240 V 50–60 Hz input, so it is designed to deliver that power continuously.

How much heat or fan noise does the brick produce when running all day?

No fan is fitted; the unit relies on passive cooling, so it runs silently and warmth will depend on load and ventilation.
