After reboot pwmconfig is lost, the system prompts no pwmconfig

I set the fan speed for my laptop, I followed the method in the arch wiki and everything works fine. I used sensors-detect/pwmconfig
I set the fancontrol file and then set it to run automatically on boot, but after reboot it doesn’t run automatically according to fancontrol, I check fancontrol.service and the system says I don’t have pwmconfig, it disappears after reboot, does anyone know what’s going on?
