I have this case, and need to plan some cooling options for it. I plan to have fans in all places possible, but just don't know how powerful they need to be in certain places across the place.

For example, I have heard that negative cooling is better for this case due to the fan facing downwards, do does this mean that I should have a higher CFM total exhausting than in-taking?

Also which fans should I buy?

In this case, there are:
2x 120mm fan mount FRONT
1x 120mm Antec TwoCool exhaust fan BACK
1x 140mm Antec TwoCool exhaust fan TOP
1x 120mm fan mount; SIDE
1x 120mm fan mount behind motherboard tray OTHER SIDE


Which fans should be put where?

Are there any fans that you could recommend to me?



I know I'm asking for a lot, however I really need help on this.



Thanks!
Dan.
