CPU Maximum Operating Temperatures AMD Athlon 64 X2 MP XP Duron Pentium II III 4 Celeron

CPU Maximum Operating Temps

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