Cooling the case means you have to get the balance right, to many fans drawing air out and not getting enough cool air in is no good and vice versa, to many in and not enough out is no good either, you need to get the balance right. I won't go into negative air pressure, bit I will suggest, 1 drawing out from the back as long as there is enough vents on your case that will be ok, but I would recommend 2 out from back and 1 in from the front, make sure you get the front fan low as possible in the case, and don't have it blowing over the hot hard drives.
