It is almost always necessary.  And you need very good thermal compounds for
this, so acquire them beforehand.  A safe bet is Arctic Silver 5, but there
are many others that will also work just as well, or even better.

They are all expensive, but you will need so little, you can just buy the
smaller container you can find.  Whatever you do, get something that does
not become too liquid at any moment, that can handle large dynamic thermal
cycles (laptops go from cold to hot to cold again several times a day) and
don't even _consider_ getting one that reacts with metals or conducts
eletricity.

If you're going to buy the covers, also get a thinkpad screws set for your
model in eBay.  Teflon-coated screws really are not meant to be reused
several times, they lose the coating.

Wah, I really wish I had a nice box like that to work with :-(
