Dear folk,
The heat problem may be problem with intermittent fan  use.
I have one old machine with two hard discs one Windows Vista one OpenSUSE.
On Vista fan always starts and keeps going. No shut down problem,
except when doing a windows  monthly update, when it might cut out,
let cool and restart.
On OpenSUSE the machine starts,  the fan does not start, (reason
unknown) and machine goes into constant re boot mode, each boot
cutting out shortly after starting.  However start and but run
'vigorously' to well overheat, machine cuts out, than a restart under
OpenSUSE  the fan cuts in at start and keeps going. No problem thereafter.
I have cleaned machine, replaced fan , but not replaced the thermal paste.
This may give you ideas.
