Instead, it specifies the processor temperature relative to the point at which the system must supply the maximum cooling for the processor's specified maximum case temperature and maximum thermal power dissipation” according to BIOS and Kernel Developer's Guide (BKDG) for AMD Processors, http://developer.amd.com/documentation/guides/Pages/default.aspx.
