There are so many more cores in the AM5729 SoC than there are in a RaspberryPi SoC. The reason heat is so high on the BeagleBone-AI is due to all these cores enabled at once. If you are not using the board connected to a display then you should disable the HDMI peripheral, GPU core, and IVAHD core through the device tree. This can be done by setting status = "disabled" for the modules mentioned. This alone will drop your temperatures to 55C. I also modified CPUfreq to run at 1GHz minimum instead of 400MHz minimum and I am still seeing 55C idle.
