I had the same error. I'm italian too and we use the comma as separator for decimals. The solution is to modify x-c1-fan.sh file.

I have done as follow:

1) Type in terminal

   cd ~/xscript
   sudo nano x-c1-fan-sh

2) Modify

   function get_temp {
     RAW_TEMP="$(cat /sys/class/thermal/thermal_zone0/temp)"
     TEMP="$(awk -v temp="$RAW_TEMP" 'BEGIN { printf "%0.2f", temp / 1000; exit(0) }')"
     echo "$TEMP"
   }
   with this
   function get_temp {
     RAW_TEMP="$(cat /sys/class/thermal/thermal_zone0/temp)"
     TEMP="$(awk -v temp="$RAW_TEMP" 'BEGIN { printf "%0.0f", temp / 1000; exit(0) }')"
     echo "$TEMP"
   }

3) Then follow the istruction in this page to uninstall the script 4) Then follow the istruction in this page to reinstall the script

Now it works for me. Sorry to all of you for my bad english

PS: I've only modified 'printf "%0.2f"' with 'printf "%0.0f"' to get the integer right away.
