try to balance airflow

input == output

normally you want the front and lower fans to be intake, and top and back fans to be ehale, as hot air rises, you want to expel that air asap. as for fan configuration, depending if you want negative or positive pressure, will affect the outcome of your case. This site had a review on positive and negative pressure airflow and its effects
