There's further information about the thermal control at https://www.raspberrypi.org/documentation/hardware/raspberrypi/frequency-management.md https://www.raspberrypi.org/documentation/hardware/raspberry... which mentions that config option 'temp_soft_limit' can also be used. Interestingly it is not used by default on the Pi 4, but is set to 60C for the 3B+.
