CPU Temp -BSD -HowTo

You need to load the kernel module with the following command :

sudo kldload coretemp

To make it permanent for the next reboot, edit /boot/loader.conf and add the following line.

coretemp_load=”YES”

To see if you can read your temperature use the following command.

sysctl -a | grep temperature

If you have two cores in your cpu you should see this output :

dev.cpu.0.temperature: 45.0C
dev.cpu.1.temperature: 44.0C

Tip: To monitor your temperature every 2 seconds you can easily use gnu-watch :

gnu-watch “sysctl -a | grep temperature”

Enjoy.
