hi all, any recommendation fan for elite 430 casing?

it has 2 12cm intake (1 x front, 1 x bottom)
and 3 12cm exhaust.. (2 x top, 1 x rear)
there is 1 stock 12cm led fan at front intake...not sure the cfm tho but the wind that blow out is not that strong.

what fan is recommended for the front intake and btm intake?
i guess for exhaust any fan will do right?
