Free software that monitor CPU temperature under El Capitan? Is there some free software that can show CPU temperature in real time for OS X El Capitan?

Any way to have CPU temperature in the menu bar? doesn't provide such an option.
Since nobody suggested it yet, you can try Macs Fan Control.
I'm using it for MBP on El Capitan 10.11.5, and it shows real temperature.
