Hello guys and gals!

As I want to improve the air flow of my system, I want to add some fan on it :D

My case is a CM 690 II and there's a lot of slots to add fans!

I am planning to buy atleast 3 fans, I don't know which yet...

Here's what I was thinking:

The cases fan emplacement

Where I want to put them (forget the #1 [remplaced by one side fan], and the front #2 fan):

So where would you put the fans? By adding 3 fans at these places, I'll have the same amout of push//pull (actually have 3 coming with the case). So which fan would be the strongest the push or the pull for for a neg or posi pressure?

Thanks for any answer & help!
