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. ck -- Hi, I am a signature virus.
