Only if workload stays the same and the system has reached equilibrium. Temperature can change in a matter of seconds if workload suddenly changes. $ cat /sys/class/thermal/thermal_zone2/type x86_pkg_temp $ cat /sys/class/thermal/thermal_zone2/temp 47000 $ while : ; do : ; done & [1] 4739 $ cat /sys/class/thermal/thermal_zone2/temp 63000 $ kill 4739 $ cat /sys/class/thermal/thermal_zone2/temp 49000 That's 15C change in about second on this laptop. My desktop will go from drawing 17W from the mains when idle, to 160W when maxing out all 8 CPUs and temperature will jump about from 40C to 95C in a few seconds. -- Tixy
