Nowadays, I *first* look in /sys. For example, this file is on my WS:
This the temp (in thousandth's of a deg C) of /one/ of the cores.
If you look in the coretemp.0 directory (where 0 is one of the sockets,
you'll see other pseudo files, like the alarm et al.
The names may well vary depending on platform and kernel version.

Today, I'll only use lm_sensors for things the kernel doesn't explicitly
export in /sys or /proc.
