You may need to go check that your configuration match's what your system actually reports.

ls /sys/class/drm/ it could be trying to find card0 or card1 etc depending on what you set in the config.

card0 is my Intel iGPU and card1 is an amd gpu. I tried setting card1 only in the config and got the same results.

I've found the root cause: the conditional on line 107 never triggers because the HWMON_REGEX on line 91 assumes that all hwmon IDs will be single digits. Mine is not, it's hwmon12. I likely have unusual hwmon IDs because I have an eGPU setup. Changing line 91 of amdfan.py from HWMON_REGEX: str = r"^hwmon\d$" to HWMON_REGEX: str = r"^hwmon\d+$" is the fix.

Cool, sounds good I'll fire up a patch when I have a chance, glad you got it working.
