this is a difficult issue, because as far as i know,
there are no tools to query per cpu
setperf/temperature.
i was also thinking about sending an email, as i think
i see something vagualy similar on my thinkpad notebook,
but how to collect data?
in a 18C room (i like cold), i start up the notebook (not resume),
that was off all night, and it goes to 46C in a couple of minutes.
fair enough, the other notebooks in the room (3) have very
similar/same temperatures (windows and linux).
for the sake of this "scientific" experiment, i don't start
anything heavy (browser, etc), just a terminal. every 6 minutes
or so, the temperature goes up 1C, and in 40 minutes, i am
at 53C and it will go up to 56C by the time i finish this email.
now, 50~58C are common temperatures for common usage on
a common notebook. but this room is 18C, and the
notebook is basically idle. (i will also boot linux on
it later to compare)
it seems to me, that at 18C, an idle CPU at 1000MHz
should be around 45~48C.
resume is a whole other thing. in a 18C room, after
a whole night of being off, temperature goes into the
high 60s and early 70C right away and it is clear
it should be at least 20 less. but i was trying to
get more data on this for a bug report.
