CPU Maximum Operating Temps

The temperatures specified for AMD CPUs max case surface temperatures. These CPUsdo not have an internal diode to measure CPU temperature. The accuracy of the CPUtemperature measurement depends on the motherboard; therefore, it is possible that theCPU overheats even though the CPU temperature reported by the motherboard is belowthe specified maximal temperature.
