Best fan placement Fractal R4

[Scottzorus]

With this setup, what would be the best fans to get and where to put them? Intake/exhaust? Really not sure how to setup the whole fan situation. The only fans I have right now are the ones that came with the case. Any help would be appreciated, thanks.

bottom front - intake
top back - exhaust

Would it matter what size?

i'm pretty sure the Fractal comes with two fans... both 140mm. one in front one on the back.

you can add 4 more 140mm fans. i'd add one on the bottom, one in front, both as intakes, and assuming you don't have any water rads, two exhaust on the top of the case. i wouldn't bother with putting a fan in the side intake, just leave it as is...
