If you have an Intel CPU (according to coretemp manpage), you can use coretemp module: # kldload coretemp # sysctl -a | grep temp [...] dev.cpu.0.temperature: 84.0C dev.cpu.1.temperature: 85.0C dev.coretemp.0.%desc: CPU On-Die Thermal Sensors dev.coretemp.0.%driver: coretemp dev.coretemp.0.%parent: cpu0 dev.coretemp.1.%desc: CPU On-Die Thermal Sensors dev.coretemp.1.%driver: coretemp dev.coretemp.1.%parent: cpu1 If you're using an AMD CPU, the right module seems to be amdtemp.
