Not necessarily. You can get surprisingly good overclocking results on most Intel chips even using the stock heat-sink/fan these days (and it has been this way for a while, at least since the Core 2 Duo days and even the generation prior to those).
But yeah, for someone who isn't even sure he wants to build his own rig and who won't be using the machine primarily for gaming the overclocking can be skipped without much real world loss.
