Due to location restrictions the only decent PWM fans I can get are Corsairs SP's (I have not seen AF120 fans with a PWM variant available, only 3 pin). I'm thinking of adding two Corsair SP120 Quiet Edition as front intakes. Are static pressure fans even worth it in this case? Not gonna be using them on radiators, these will only be pulling air through the front panel of the Air 240 so is it restrictive enough to make the static pressure fans worth it over high airflow fans?
I ran NZXT's Grid+ V2 controller for a while to voltage control the fans and get a decent number of individual channels. Something like that can help you make cooling more subtle.
As for pressure fans or not... I'm moving to SP fans only - I found that AF type fans are just really bad at overcoming resistance (and need to spin much faster to compensate). A filter or even the fine meshed grills on the 240 throws up a quite some resistance. The only reason I'd go with an AF type fan now would be if I needed a targeted airflow.
Btw Corsair's MLs are PWM. I will be trying those soon and see how they stack up vs the EK Vardar F1s... the twin pack makes them affordable at least.
