Corsair 750d Fan orientation and type?

[adam1901]

Hi,

I have a Corsair 750D currently with the stock fans.
My specs:
Intel 4930K
Corsair H100i (Stock Fans) Pull
2 Gigabyte 970 Windforce (Note the design blows hot air into the case)
32GB Dominator Platinum
Asus ROG Rampage 4 Black Edition
EVGA 1000w p2 PSU
1 HDD cage (Filled with 2 4gb hdd and a 4tb WD Black at the top)
and a few SSD's

I just brought the corsair commander Mini, and at the same time am going to upgrade my fans.
I was planning all quiet editions & PWM:
2 AF/SP140 for the front
1 AF140 for the rear
4 SP120 for the H100i
1 AF/SP for the bottom + Filter

So my questions:
Would the SP be better for the front because of the semi limited airflow or would the AF series do just as good?
What orientation should i have them in:
Currently the 2 SP120L on the H100i are an intake in Pull and the rest of the fans are in stock orientation.
Should the H100i be an exhaust and the back 140 as well or the h100i as an intake with the 140 still exhausting?

Thanks
Adam

That would create a negative pressure though.
