How to use to use lm_sensors on a Fedora Linux?

Once lm_sensors is installed you need to type:
$ sudo sensors-detect
Next hit ENTER key for everything it suggests. At the end it will ask you whether to add what it finds to /etc/modules. If you are happy with the output i.e. findings type “yes”.

To see the values for the hardware sensors detected on your motherboard / server, type:
$ sensors
Sample outputs:

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +37.0?C  (high = +80.0?C, crit = +90.0?C)
Core 0:         +32.0?C  (high = +80.0?C, crit = +90.0?C)
Core 1:         +29.0?C  (high = +80.0?C, crit = +90.0?C)

Or use the following command:
$ sensors | less
$ sensors | egrep -i --color 'fan|cpu|temp'
