Fan Orientation help!

Hey guys, I have two questions. 1st do I have to plug in three cables for each sp120 fan in the 460x? Or is there like an included splitter for them so I only need to use one?

 

My second question is that I also have an additional 120 mm fan to use as an exhaust. And I have two 140 mm fans for the top but here is where I have a problem. Should those two be intake or exhaust because I want a positive airflow and am worried if they are exhaust then I would have a negative airflow. I know that I could change the speeds to compensate but I have a motherboard with three fan jacks and I have a fan splitter so I wont be able to control all of them. Any solutions? Thanks in advance!

Only stick one extraction fan in the top and one in the back....

would adding 1 140 as intake towards the front and the back 140mm as exhaust present any problems?

It'd be pretty close to even, and maybe slightly positive (obstructions around the intake fans) If your worried, grab an incense stick and wave it around the case to see where the smoke goes.

fan support is listed as 2 x 140mm in the top, if you can get some seperation between the two then maybe, otherwise I'd avoid having an intake right next to the outlet as I could see the turbulance puishing half the air from the front fans under the graphics card with no easy way to escape.
