What type of fan is recommended?

[Tsviki]

Im planning on getting 2 new intake front fans from corsair (will fit perfect with my 400C im considering buying).
My question is - what type of fans are recommended? there are 2 types - AF (Air Flow) and SP (Static Pressure). Im not sure what to get for intake.

May Linus be with you all!

I think for intake you are going to want AF fans, static pressure I think is normally used on a RAD.

Static pressure is used for when the path of the air flow is constricted, like the fan is between the hard drive cage and the mounting area.
