CPU Temp Optimization

The CPU Temp throttling occurs at 75ºC in order to be run inside a case but if you have a good heat-sink you can use the new bpi-m2-zero-v4.dtb_5.6.13-server that starts throttling at 80ºC which has a better performance. Thermal throttling is now at 80ºC.

instructions

1 - Login (shell cmd)
2 - cd /boot
3 - sudo mv bpi-m2-zero-v4.dtb_5.6.13-server bpi-m2-zero-v4.dtb_5.6.13-server-BAK
4 - sudo wget https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/download/v3.6/bpi-m2-zero-v4.dtb_5.6.13-server
5 - sync && sudo reboot
