Suggestions on case fans

Andreas W said:

SP = Static Pressure used for radiators/liquid cooling because of the larger blades they pushes the air trough while a regular fan does so too but some of the air could go reverse because of to little pressure.

AF = Air Flow those would be good for intake fans since they focus on bringing in as much air as possible and spread the air.

So if you using them on the side of your chassi the AF would suit your need better

Oh ok thanks for explaing that to me Andrew,I have decied to get the AF120 Corsair silent twin then.Thanks everyone for your suggestions and advice,really aprecieate all your guys input.
