Well I always imagined that its there to not let the pressure build up insdie the IHS. If your going to say "yes but you cover it with the heatsink" then we are not thinking the same amounts of pressure.

My guess, it has something to do with the manufacturing process, what IDK.

Its a breather hole. Its so that a little more heat can be dissipated from the Core Die.

Also, the 'glue' that holds the IHS to the CPU doesn't go around all 4 sides. Theres a gap. I'd assume its for the airflow but who knows.
