I have a fractal r4 was wanting to add 2 fans. what would be best placement?

I have a corsair h100i gtx mounted in front with 2 intake fans wont fit on top
stock fan on side is intake on duel gtx 970 and stock exast fan.
should 2 new fans be on top as intake or exast or 1 of each or make 1 back and 2 top intake and side next to duel gtx970 be exast?

What Zerk2012 said, but I would only use the rear roof exhaust. Keep the front and/or middle roof vent open without a fan if they are in front of your CPU heatsink as noted in the article below (if you need the extra cooling). I think you will have one fan left over which I would put as a floor intake fan.
