You should clean off the old thermal-transfer compound from the
heatsink, and replace it with a fresh, thin layer. If your CPU uses one
of those "thermal pads" it should be replaced with a new one.

Modern CPUs need good thermal transfer to the heatsink, never try and
reuse the old stuff.

If you are upgrading to a faster CPU you may well need a larger and/or
more efficient heatsink.

Some outfits will not honor a CPU warranty unless a proper heatsink was
purchased at the same time, and many retail packages come with one (as
was mentioned).
