I have always used my MacBook on 'better battery life', and it has run
with no fan noise or noticeable heat. But recently I now hear the fan
and the top-left bottom gets very hot. Is this due to a faulty Mac OS X
update that I recently applied?

TIA,
Dan

Open up "Activity monitor" and see if you have a process that's stuck
and using a lot of CPU. Firefox has done that to me, and a "normal"
Force Quit won't clear it, because the stuck process is not visible to
the "Force Quitter"; Activity Monitor can identify it and kill it dead,
though.

For me, network activity seems to activate the "jet engines"...
