Hole on the Celeron D?

[VT-Vincent]

I realize this is a very noobish question, but I am curious, what is the hole in the corner of the Celeron D processor (and most other Intel processors for that matter) for? I ask because I am moving my Celeron D from my Dell Optiplex to an Asus S-Presso barebone and I realized that thermal compound had made it into the hole.

It's just an aerating hole, the glue/thermal stuff that intel puts between the actual core and the heatspreaders is applied, obviously, moist. as it dries, the hole is there to make sure there is not negative/positive pressure


i think it's okay if paste goes in there...

Hole on the Celeron D?

That's where the poop comes out.


I'm looking for the intel design document now. Will post better answer later.
EDIT: Found THIS Seems like a plausible reason to me. There is no reference to it in any of the docs for the Celeron, CeleronD or Pentium4. I don't remember seeing the hole on my C2D....maybe they don't use epoxy anymore, and therefore don't need a vent hole?
