New computer- cooling?

I am days from ordering my new computer parts and start building but before I do that I was wondering if I need any extra cooling other then what will come with the parts.

Here is my case it looks like it will provide good air flow. Ill also be adding another 120mm case fan to the side of that.

I'm not sure on how good the stock cooler is for the C2Q 6600 so will I be needing to purchase a cooler on my own?

I would appreciate any help I can get on this. If you need anything else please don't hesitate to ask.
