After initial panic, I started testing. On Linux the temperature can get
as high as 60, while on windows it reaches 32 in idle.

I rebooted the machine instead of hibernating it, and I started issuing
some dummy test commands (whilte true; do cat /dev/null > /dev/zero)
while quering the temp of the machine (watch -n1 cat cat
/proc/acpi/thermal_zone/*/*). I can see the temp getting high from 52 to
62, and then the fan started working (I also added another test thread
to test the other CPI, as this is a dual core machine). The highest
temperature I measure was 62 with fan working lightly. The lowest
temperature measured was 49.

Then on the second test, I hibernated the machine and on restart I did
the same tests. Now on 2 "cat" threads, the temperature was up 72, and
the fan was not working at all. When I stopped the test threads, the
temperature did not drop down as on the first tests.
