Xtreme Triple PA120.3 Cooler

[HaCKs]

This is going to make me look like a HUGE llama, especially in the wake of those amazing pictures, but what screws are those holding the fans to the rad? I would love to be able to have that look! The screws I have now go all the way through the fan into the rad.

P.S the actual size of the screws is what I need, so I can stop at fastenal on my way home from work.
