Your variables are set wrong. If your GPU is card1 they should be:
HWMON=$(ls /sys/class/drm/card1/device/hwmon)
FILE_PWM=$(echo /sys/class/drm/card1/device/hwmon/$HWMON/pwm1)
FILE_FANMODE=$(echo /sys/class/drm/card1/device/hwmon/$HWMON/pwm1_enable)
FILE_TEMP=$(echo /sys/class/drm/card1/device/hwmon/$HWMON/temp1_input)
The "HWMON" variable is there to determine which actual hardware monitor is
being used because it can change whenever you boot. One time it could be
hwmon1, the next time hwmon3, etc. So you can't hard-code it as you're doing.
You have to use the $HWMON variable to set FILE_PWM, FILE_FANMODE, and
FILE_TEMP.
