linux - Which of the below is my CPU temperature -

goal

measure cpu temperature of linux box.

work done till now

i have installed lm-sensors detect temperature , below output of command sensor:

root@xxxx-xx :# sensors  acpitz-virtual-0 adapter: virtual device temp1:        +66.0°c  (crit = +255.0°c)  k10temp-pci-00c3 adapter: pci adapter temp1:        +65.4°c  (high = +70.0°c)                        (crit = +100.0°c, hyst = +99.0°c)  radeon-pci-0008 adapter: pci adapter temp1:        +64.0°c  (crit = +120.0°c, hyst = +90.0°c)  radeon-pci-0100 adapter: pci adapter temp1:            n/a  (crit = +120.0°c, hyst = +90.0°c) 

the output of cat /proc/cpuinfo is:

question

out of above readings command sensor , cat /proc/cpuinfo, not sure my cpu temperature in output of sensors , 1 one relation between output of both commands (ie: field (ie:output of sensor) matches field of cat /proc/cpuinfo).

your cpu temperature shown k10 sensor, beware assumed inaccurate.
