Before proceeding, ensure you have:
Log into your FydeOS account and navigate to the desktop.
Access the bash shell environment via crosh (Control + Alt + T) or tty.
Enter sudo su

file.
Enter the command cp /usr/share/rock5b/rock5-fan-control.conf /etc/init

After completing the above steps, restart the system to apply the changes.
Congratulations! You have successfully enabled the PWM fan for the Radxa Rock 5B.
