Background
I’m using Conky for monitoring the system. After a system upgrade, the CPU temperatures were gone. Conky’s standard error showed the following.
Conky: can't open '/sys/class/hwmon/hwmon0/temp3_input': No such file or
directory please check your device or remove this var from Conky...

An easy fix would be to adjust the following lines in .conkyrc according to
the number N in /sys/class/hwmon/hwmonN containing the file temp3_input.
(You may adjust the number 3 according to the number of CPU of your device.)
The number of CPU can be found using grep -c ^processor /proc/cpuinfo.
