Interesting, never had that happen to me, but then perhaps you are using a laptop with a dgpu? I have not been. My laptop generally consumes 4w at idle and up to 15w under load, so I don’t see this ever outpacing the 60w charger. The CPUs with the highest tdp are only around 100w anyway right? And in that case the laptop comes with a higher wattage charger. But you’re right I guess it could happen depending on the hardware, never personally seen it however.
you can keep the fan and heatsink on the board
