Cooling options for new computer

[beamer7296]

I will soon have my new computer:
Case: NZXT Apollo
Mobo: evga 680i
Processor: E6600

I will be doing some overclocking, but nothing too extensive. Can someone reccomend what I need to keep the system cool? The case comes with:
1 x 120mm Rear Fan
1 x 120mm Blue LED Fan

What do I need in addition to this? Perhaps a CPU Fan and Heatsink with maybe one or 2 more case fans? Please post your thoughts and reccomendations!

Thanks!
