Hi I'm currently looking at getting a fan for the front of my NZXT Phantom(Original) and I'm wondering if a static pressure or a airflow fan would suit my system best. I'm looking at getting some CORSAIR AF or SP series fan as I've heard a lot of possitive response to these fans. Are there any quiet fans in either 120mm or 140mm you can recommend other than the ones from corsair. Would Noctua be a better choice? And last but not least, should I use pressure or airflow fans for the front?
