Wiped existing installs. Did standard full install with MATE
desktop without print server or activation of networking. Added
mate-system-tools and mate-sensors-applet (which is now
displaying core temperatures). This sequence did *NOT* install
thinkfan. However it is obvious that something is triggering the
fan when a core temperature hits ~40 deg C.
I'll not pursue the installation of thinkfan as I see no benefit
and do see the possibility of breaking something. I'll continue
to investigate the various display and logging apps available.
Thanks to all.
