Airflow or Static Pressure?! Also PWM Y-cables

Hi there,

so i got a Aerocool XPredator X1 Devil Red Edition Case and i want High Airflow! I plan to put a H100i in there (with 2x Corsair SP120 LED pushing) and 3x Corsair AF120 LED (two in front and one in the back) and 2x Corsair AF/SP 140 LED (Side).

So the First question is = should i get 2x 140 AF or SP? I want the 140mm Fans to cool the VRM and the Graka (vga card) so what is better Airflow or Static Pressure?

Also i dont have enough fan headers and i plan to use PWM Y-cables, but is this a good idea?

This is how it will look like.

 

 

PS: Sorry for my English

Airflow - Unrestricted; case fans

Pressure - Restricted; Heatsinks, radiators, HDD cages and such

On the PWM splitter, I use one for my heatsink (fuck you Gigabyte and your single CPU fan header too) and it works as you'd expect (very well), you just make sure you use the same model of fans for best results because you can only read the RPM of one fan

Depending on how many fan headers you have, this may be a good idea,.
