Hello, I'm posting here, because i belive tomshardware is an aproperiate site to ask a competent question. I own a haf xb case with seidon 240m in push pull configuration and i would like to replace the fans from stock into some quieter and better performing fans. And here is where my question appears: what kind of fans should I use? SP or airflow? Cm's radiator is quite thin and got around 26 fins per inch. I assume push-pull config keeps the airflow the seame, but doubles static pressure am I right? So I would like to go with Noctua NF-S12A. I think i would take more advantage of highier air flow on this rad, but is the sp of 2 of theese enough to make it thru ?
