Corsair Air 240 Fan Placement

Recently finished my first build and I'm looking to replace two of the stock 120mm fans that came with the Air 240 case. It comes with three case fans altogether but I think I can get away with just two fans. This is what the default fan setup looks like (one on top and two in the front) - what would be the optimal placement for two fans instead of three? Any advice is appreciated.

Cheers
