[Ti] TiBook Overheating

[Rafe Day]

Dennis:

Thanks for your advice.  I checked vents and blew everything out, but
nothing appeared clogged.  No luck there.  Then I disassembled the thing and
it thermal connectivity *appeared* solid between the processor and heat
sink.  This is definitely the source of the heat, so should I try applying
more thermal grease?  How much is the *right* amount for a TiBook?  Is there
a brand that someone really recommends?  I'm currently getting about 30
minutes of work time before I need to give it a 20 minute break.  Since I
live on this thing, those aren't optimal working conditions.

As always, your insights are appreciated.  :)
