CPU Operating Temperatures
AMD Athlon and Duron
Socket A CPUs
(Athlon, Duron) up to 1GHz 90°C
Socket A CPUs (Athlon) 1.1GHz or more 95°C
All Slot A CPUs
(Athlon classic, Athlon Thunderbird) 70°C
AMD K6 series
All K6 CPUs
(166-300MHz) and most K6-2/K6-III CPUs 70°C
K6-2/K6-III CPUs,
model name ending with X (e.g. K6-2-450AFX) 65°C
K6-2-400AFQ (uncommon) 60°C (!!!)
K6-2+, K6-III+,
most mobile K6/K6-2 CPUs 85°C
mobile K6/K6-
2 model name ending with K (e.g. mobile K6-2-P-400AFK) 80°C
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.
Intel Pentium III
Pentium III Socket 370
500-866MHz,
Pentium III Slot 1
(first generation, OLGA) 550-600MHz,
Pentium III Slot 1 ('Coppermine') 500-866MHz 80-85°C depending on model
Pentium III Socket 370 and Slot 1, 933MHz 75°C
Pentium III Slot 1 933MHz 60°C (!!!)
Pentium III Slot 1 1GHz 70°C for newer versions
60°C (!!!) for older version
Pentium III Slot 1 1.13GHz (first version) 62°C (!!!)
Pentium III max temperatures are the maximum temperatures reported by the thermal junction inside the CPU.
Intel Celeron / Celeron
Celeron 266-433MHz 85°C (max. CPU case temperature)
Celeron 466-533MHz (0.25µ) 70°C (max. CPU case temperature)
Celeron 533-600MHz ('Coppermine) 90°C
Celeron 633 and 667MHz 82°C
Celeron 700MHz and more 80°C
Celeron max temperatures are the maximum temperatures reported by the thermal junction inside the CPU, unless otherwise specified.
Intel Pentium II
Pentium II (1st generation, 'Klamath') 72°-75°C depending on MHz
Pentium II (2nd generation, 2.0V core), 266-333MHz 65°C
Pentium II (350-400MHz) 75°C
Pentium II (450MHz) 70°C
Pentium II temperatures are the maximum temperatures of the thermal transfer plate (on which the heatsink is installed).
