I'm looking to add an intake fan to my case (NZXT S340) and have my eyes on the Corsair AF140 and Corsair SP140 fans. One is airflow optimised and the other static pressure optimised.
Which one should I get? There are no obstructions like drive cages in the case but there will be a dust filter in front of the fan.
Get the AF140s. Dust filter doesn't provide significant air resistance compared to a radiator - they are designed to provide as little air resistance as possible, and will run quieter at a given RPM because of their blade design. You can also run them at lower RPMs and get the same air flow, so your system will be quieter.
