Airflow control in Corsair 300R

About ready to take the plunge, but looking for some advice on cooling and airflow control.

Case: Corsair 300R (stock 140mm front intake, stock 120mm rear exhaust)
Mobo: Intel Z77-50K (3 fan connectors: front, rear, processor)
CPU: I5 3570-k
GPU: GTX 670

As my system is mid-range, I don't expect it to get too hot, but I do want to treat it well, and I live somewhere that is rather hot during the summer.

I have read that the Hyper 212 EVO is a good choice, so I'm onboard with that.

The Question: Do I need more case fans, which fans should I get if I do need more fans, how should I place them, and what will I need to hook them all up properly (ie to fan controller, to power supply, etc.)?

Strongly considering at least one fan for top exhaust, but don't have much experience in this area.

Thank you!

    Normally for a positive pressure, Front,bottom and Side as Intakes and top as exhausts will serve good. (for normal Heatsinks)

    If you are doing a push-pull with Hyper 212 Evo, this type of airflow would be perfect(positive pressure). Front,side,bottom and 1 top fan as intake and back,top 1 fan as exhaust will keep everything hyper cool.

    With my corsair 500R and a hyper 212 evo, the top config gave me very good temps.

    For case fans, you can choose from:
    1) Noctua NF-P12(120mm) for case fan and Noctua NF-F12 for Heatsink fan(120mm)
    2) Corsair AF-120/140 (for 120mm/140mm) for case fan and Corsair SP-120 for heatsink(120mm)
    3) Silverstone AP 121/141 for case fan (for 120mm/140mm) which topped the performance chart in tomshardware tests(check the link below)

    For LED fans and other comparisions check this :

    I'm using 2x120mm Noctua NF-P12 and 2x140mm Corsair AF-140 on my Corsair 500R, they are dead silent and doing the job well.
