Yes that is obvious. But it seems claymore is modifying values in /sys/class/drm/card1/device/hwmon/hwmon3/pwm1_enable which can be chowned, or setfacl-ed for the specific user. Since app is closed sourced I cannot tell exactly what it is doing.

If claymore could chime in, I could modify underlying permissions on the system so it doesn't need root.

Is there a way to let claymore control fan with -tt flag (linux amd-pro drivers) without giving it root permissions?

I feel dirty running it as root.
