I just did a soft reboot and right afterwards I get:

$ cat /proc/acpi/thermal_zone/THRM/temperature
temperature:             63 C


waited a few seconds:

temperature:             62 C


After a few minutes (while connecting back home):

temperature:             58 C


And right now:

temperature:             56 C


So it is going the opposite direction after a soft reboot.
