Airflow vs Static Pressure fans (Corsair vs. ID-Cooling)

[gabrieltkd95]

Hello, i'm searching for two 120mm fans and I want them to go at the bottom of my pc case (Corsair 780t) as an intake fan configuration. Right now im between these ones:

ID-Cooling:

http://www.idcooling.com/Product/detail/id/102/name/SF-12025-W

Corsair (120mm):

I don't care about the noise, only want the better quallity/performance. What do you recomend me?

Also, I really don't know why the ID-Cooling PL ones have more static pressure than the SF ones. Can someone explain me why? or which one is better?

Tbh the total system cooling performance differences between those fans will be minimal, just choose the ones you think look better.
The PL ones have a higher max RPM (2200) than the SF (1500), likely why they have a higher maximum static pressure. From the (claimed) specs, the ID -cooling PL fans look decent.

While fans are fans are fans and it isn't an exact science, Static Pressure fans are only meant for use on water cooling radiators.
They are designed to be better at pushing the air through the restriction of the fins.
While you can use a static fan as a case fan, you don't want to use an airflow fan on a radiator.

The PL fans have a higher static pressure because they can spin much faster to make more airflow.
But the blade design is not optimized to push air through a radiator.

I have Corsair AF120 with lights, Nocuta SP140 and be quiet! SilentWings fans.
I like the be quiet! fans for best performance, but they are expensive and don't come with lights.

Also, if i want them for a bottom intake where i have a dust filter in front of the fan but nothing behind, should i use AF or SP fans?
