Umm actually your explanation doesn't make sense. What you want is to keep air flow in your case circulating, expelling hot air and sucking in cold air. Since Hot air rises, what you need to do is make sure the exhausts are expelling the hot air as it rises to the top. Front fans are usually intake fans because they bring in cold air from the outside to the bottom of the case and thermodynamics will take it to the top of the case where it can be expelled. That's why good cable management makes such a big difference in the cooling of a case.. hot air doesn't get trapped behind obstructions and ill placed cards.

When you want to drink something the quickest way is usually to stir it with a metallic object (ie heatsink). Standing in front of a fan works because the airflow is designed to be channeled through the front. Imagine if you were sitting in a box with a wall to your back - all the hot air would just be blown towards you and get trapped in the back. You would still feel hot because you would just have hot air being recirculated around you. If you stand in a wind tunnel with no wall to your back, you'll be a lot cooler because there's no hot air to get trapped behind you. That's why having an exhaust where your graphics card/processor is probably a best idea esp since those pieces are producing the most heat.
