I can't seem to find anywhere that mentions a Noctua 140mm fan for case airflow, NOT static pressure/ heatsinks and radiators. Everywhere I go, The NF-A14 fans are all assosciated with heatsinks and radiators/static pressure and I am beginning to get frustrated. Do they even make a 140mm fan for airflow NOT cpu coolers? If someone finds an answer for me, please tell me where you found your answer. Remember that I do not have any restrictions blocking airflow, these are going on the front of my Corsair 750D and have the drive cages at the bottom.
