I am looking to get some noctua 140mm fans for my Corsair 750D but I am not sure which one is optimized for airflow. I do not have any restrictions blocking airflow. Here are the fans.
NF-A14 FLX
NF-A14 PWM
NF-A14 ULN
NF-A15 PWM

NF-A14 PWM is the most powerful one, running at a constant 1200-1500 RPM

Specifications:
140x140x25mm, square frame
4-pin PWM, 1500/1200rpm max.

Hope I helped! :)

The problem is that I am not sure if that fan is better for radiators and heatsinks (static pressure) or for case airflow.

Oh now I understand;
Noctua NF fans are focused on case airflow so yeah you could get any of those but the PWM provides the best efficency :) 

Sorry for not getting it, I thought you were asking me which one provided the best airflow performance :/ 

Hope I answered your question now!

Have fun upgrading (if you are)!

My problem is that everywhere I go, everyone only taks about these fans for static pressure (heatsinks and radiators). I need to find a source that tells me that the fan would be for airflow and not static pressure. The NF from what I know does not mean that it is for airflow. They all say NF, even their 120mm fans made for static pressure. I just cant find anywhere in the world where someone mentions 140mm Noctua fan or airflow and NOT static pressure.

NF is the product...
And yes, 140mm, being the most powerful means it's probably going to improve the airflow.

NF-A14 FLX is optimised for cases/ radiators etc. For your situation I wouldn't recommend the NF-A14 PWM.
