Note: I just did a swsusp and resume and here's the same data:

$ grep . /proc/acpi/thermal_zone/THRM/*
/proc/acpi/thermal_zone/THRM/cooling_mode:<setting not supported>
/proc/acpi/thermal_zone/THRM/cooling_mode:cooling mode: passive
/proc/acpi/thermal_zone/THRM/polling_frequency:<polling disabled>
/proc/acpi/thermal_zone/THRM/state:state: ok
/proc/acpi/thermal_zone/THRM/temperature:temperature: 60 C
/proc/acpi/thermal_zone/THRM/trip_points:critical (S5): 88 C
/proc/acpi/thermal_zone/THRM/trip_points:passive: 81 C: tc1=4 tc2=3 tsp=100 devices=0xcf6c2338

And just leaving my system idle for a few minutes:

$ grep . /proc/acpi/thermal_zone/THRM/temperature
temperature: 62 C

and a few more minutes:

temperature: 64 C

And a few more:

temperature: 66 C

right now after typing this:

temperature: 69 C

So this definitely shows somethings not letting the CPU rest.
