Also it is strange the out of 3 temp sensors the second one How would it know ? That is why the configuration file supports the "ignore" statement. Also, why is it strange ? There is no requirement that a board vendor MUST connect sensors in a certain order. > shows -70 degrees: > # cat /sys/class/hwmon/hwmon1/device/temp1_input > 33000 > # cat /sys/class/hwmon/hwmon1/device/temp2_input > -70000 > # cat /sys/class/hwmon/hwmon1/device/temp3_input > 46000 > If I get the meaning of the readings well, that 46 Celsius is the > core temperature.
