Its important to put (enough and ) not too much. If there is / are raised
part(s) in the middle of the cpu chip with grooves around you don't want it
running into the grooves (actually I guess they are there to catch spill but
...) it can conduct across which will make it non functional. some people
say put it on and wipe it off -- you just need a very very thin layer of it,
just on the central parts. Even if there are no such grooves the point is it
is not supposed to contact anything other than the metal parts which contact
the heat sink or ooze out anywhere.

Also to use the heatsink that goes with the cpu and fan if any. Checking the
fan power rating if it is higher compare the power supplies also. The
graphics cards can draw a lot too if they have fans especially so if
uncertain leave that out to start.
