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

Okay.... Let me get this straight.
Positive = more air being intake than being exhausted i.e. 4 cars enter a tunnel and only 2 comes out
Negative = More air being exhausted than air being taken in inside the case
Neutral = the amount of air going in the case is equal to the amount of air going out of the case
This is why I mentioned using Silent fans at silent settings as exhaust and use performance fans at performance settings (the rpm). To get more air in whilst having the silent fans gradually exhausting the air inside. This means = Positive pressure.
But this also depends, because you can always adjust how fast the exhaust and the intake fans run. If you run them at max then they will have different pressure's. But this is mainly if you have mixed fans.
In the other hand if you use the same fans across the case. say use 6 Silent Fans at Silent settings (rpm) and put 3 exhaust and 3 intake that means it has a neutral pressure. And its also easier to determine if its Positive, Negative or Neutral by easily just changing the number of fans doing exhaust or intake because now they are all the same fans.
Though what I recommended was:
3 intake (2 performance fans up front for intake, 1 performance fan at the bottom beside the PSU as intake running at performance setting (the rpm))
and 3 exhaust (1 "Silent" fan exhaust from rear, 4 "Silent" fans push and pull connected to the rad exhausting out the top by silent = less rpm = less noise which is also = less cfm fan and have the silent fans run at silent settings) = This should show as a Positive pressure but Can become Neutral/Postive/Negative if you change the rpm via mobo, or fan controller's.
But if you keep the silent fans at rpm's to keep it silent + the performance fans at its performance level rpm then, it will mean that the case gets more intake than exhaust which means a Positve pressure...
In theory if the Silent fans are run at silent settings, they will exhaust less air unless you run them at max rpm.
Although now a days there are alot of fans that have innovative blade design's that allows more cfm without having to crank up the rpm of the fans which causes louder fan's.
I see some folks recommending fans mainly Phantek's, Noctua's etc

Hey
I would go about:
>1 Exhaust from the rear
>all 4 fans in the H100i doing push and pull also as Exhaust taking air inside and blowing it outside of the case through the top. (this will also avoid dust from collecting at the top of the case which happens if you put them as intake)
>2 fans up front as intake
>1 fan at the bottom as intake
>PSU with fan grill facing downwards to intake outside the case through the bottom and exhausting it through the back grills
All silent/quiet fans use them as exhaust.
All non quiet oriented fans use them as intake.
