Here is the thing, I've got four case fans, two in the front two in the back and they are all set to blowing air into the case. However, I was thinking that maybe it would be a good idea to have two fans on suck and two fans on blow, which would push air into the case and then suck it out after it reached the other side. Would this be a good idea?
 
I have mine set to where the 2 in front suck in air and blow towards the back, and the 2 back one blow out.
 
you definitely wouldn't want them all blowing in or all blowing out because the air inside the case wouldn't be moving around much.

typically optimal solutions are to pull in from the front and exhaust out the back.

rear case fans are usually positioned higher up on the case than front fans, and heat rises, so they will be pulling the hottest air out of the case (typically).

so yeah...what he said.
