This model of thinkpad has 8 levels of fan control:
0=off,
1-2 = 1900 RPM
3-5 = ~3000 RPM,
6-7 = ~3500 RPM
and a disengaged mode works at ~5100 RPM
The 6-7 level @ 3500 RPM should be enough to dissipate heat generated by
a loaded CPU. The fact that your fan is running at 3500 RPM is
indicating that the fan control is correctly enabling the highest fan
control level (6-7) and even that is not enough to dump all the heat out
of the laptop. Also, thermald should be actively throttling back the
CPU as a passive mode control, so this should also help reduce the
overheating. The fact that this seems to be occurring across a wide
range of kernel versions suggests to me that that perhaps this is
hardware related, for example, is the thermal paste between the CPU and
the thermal pipe/fan unit working correctly?

Title:
Shuts down when supposed to suspend as a reaction to self-caused
overheat, session lost
Status in linux package in Ubuntu:
Confirmed
Bug description:
Error:
Kernel foolishly shuts down the computer when it overheats.
/var/log/kern.log
W500 kernel: [1448.648529] thermal thermal_zone1: critical temperature
reached (100 C), shutting down
Consequence:
Shutting down destroys session in Ubuntu, Gnome, and all applications that
can't remember their latest conscious state (most applications).
Attempted repair, failed:
Laptop has suspending ability, but I can't find the setting for the kernel to
make the computer suspend instead of shutting down.
Repair suggestions:
1. Persistence of session, so that everything would reappear after the
restart. (this would also make updating less disruptive)
2. Do not heat the machine like crazy; speed up fans or slow down processes.
(problematic Lenovo Thinkpad W500 fan on low speed right up to the fiery end)
3. Put the computer to suspend when it's too hot.
(The problem has remained the same from at least Ubuntu 11.10 through
14.04)
