I have a very similar problem on my mac at work.
I don't know atm how to look up the critical temperature that is
fused. My mac reported only 55 degrees for the one cpu.
The critical temperature can be read from the device-tree if i remember
it correctly.
I heard that there exists a bootable CD which contains a tool to refuse
the CPU. Dont know where to download it, so my pragmatic solution was to
relocate the machine to a room with air conditioning ;-)
And I also run the ONE cpu at lowest frequency.
