Opnions wanted for case fans layout

Hi guys,

I have bought the case Aerocool S9a, and it does not have an exhaust on its top. I have 4 120mm fans to arrange the cooling layout, which will be controlled by an external fan controller. I have made a first arrangement which can be seen here:



So, I have 2 intakes at the front, 1 intake at the side, 1 exaust at the rear. This way I make two different and independent flows of air, separated by the videocard, as can be seen. Maybe a good alternative for this case?

The configuration is a 3770K with 212 Evo, and a XFX 7950 Black Edition Double Dissipation (2 fans).

This case has another place at the side to attach another 120mm fan, but it is blocked by the 212 Evo.

I want your opnions about the cooling performance of this setup and if I can do anything to improve the cooling given my restrictions?

Thanks
