Thermal_zone0 & thermal_zone1

There are 2 thermal zones in sys fs:

  • /sys/class/thermal/thermal_zone0
  • /sys/class/thermal/thermal_zone1
    reporting different temperatures.

thermal_zone0 seems to be the CPU temp (It rose when running a stress on all cores). Meanwhile thermal_zone1 just rose slightly. So what is thermal_zone1?

TIA!

cpu gpu ? and here to make 15 characters
