Pi 5 8 GB with heatsink instead of a fan. Used for server experiments that will need bursts of maximum speed, not continuously running hot. Stays cool. Is kool.
Testing with externally powered monitor and keyboard for reconfiguration. Still stays cool.
Yesterday I plugged in a USB powered monitor drawing 8 watts from a USB 3 port. This is for a luggable Pi in a slim case project. It means I can lug just one power block instead of two.
Left it idle at the desktop screen. Nothing running. On return, the whole board was hot. CPU and GPU at 68°. The USB 3 socket was worryingly warm, a first ever on any computer. The motherboard base was warmer than a motherboard should be. I raised the board up to get airflow underneath.
Is this normal when using lots of USB power?
