Should a CPU fan blow cool air into the heatsink or suck the heat off it?

Just wondering which way up to put my fan. In my mind's eye, I would imagine blowing pushing cool air into the bootom of the heatsink better, but sucking would pull the heat away from the motherboard instead of blowing it all over it.

Is there a right or wrong way?
