Same problem with Kubuntu 12.04 on ThinkPad W500. System went into thermal panic and shut down when doing an rsync copy onto an encrypted root filesystem.
Using cool_cpu.sh with level set to disengaged, the CPU speeds vary between 800 and 2534. Fan speed goes up to 4590. Temperature stays stable.
Sensor 1 seems to be CPU.
Interestingly I have a W520 that has never overheated running Kubuntu 10.10 (or previous versions), even under such heavy load that screen updates slowed down. So the W500 seems to be particularly problematic.
Also, the machine won't boot with the performance setting at "Balanced".
