The existing script has worked well for me on Raspberry Pi OS Desktop. However, I had to install Raspberry Pi OS Lite and found that the fan curve does not work after a reboot. I've created a pull request to fix this issue.
To fix it manually, edit /lib/systemd/system/pigpiod.service and change the ExecStart line to
ExecStart=/usr/bin/pigpiod -l -n 127.0.0.1
