Is it better to have a fan blowing on the pi or blowing out?

@xeon my case has holes at the bottom so it blows onto the arm CPU then the air goes underneath and out the case
When it sucks the flow is spread over a large area.
When it blows the flow is aimed directly at the cpu.
So a larger amount of air hits and pushes away heat when blowing directly on the cpu.However blowing increases dust build up and sucking decreases it.
Choose wisely.
