Not sure about the older Athlon CPUs, but the 2 generations of Ryzen's I
have seem correct as well as an APU
CPU: AMD GX-412TC SOC (998.17-MHz
K8-class CPU)
CPU: AMD Ryzen 7 3700X 8-Core Processor (3593.33-MHz
K8-class CPU)
CPU: AMD Ryzen 7 2700X Eight-Core Processor (3693.17-MHz
K8-class CPU)
e.g. at idle
# sysctl -a dev.cpu.0.temperature
dev.cpu.0.temperature: 31.1C
then start up
# cat /dev/urandom | openssl sha256
# sysctl -a dev.cpu.0.temperature
dev.cpu.0.temperature: 57.1C
It agrees with what IPMI reports too from the MB
# ipmitool sensor | grep "CPU Temp"
CPU Temp | 31.000 | degrees C | ok | na |
na | na | 93.000 | 94.000 | na
And on a fanless APU
# sysctl -a dev.cpu.0.temperature
dev.cpu.0.temperature: 62.6C
# sysctl -a dev.amdtemp.0.core0.sensor0
dev.amdtemp.0.core0.sensor0: 63.1C
