Pajamas in the Daytime

I have two box-fans and no air-conditioning.  What is the best way to cool my house?  I spend most of the day in the living room, with spots of kitchen-ness, and the night is bedroom-time.  My initial thought is to put one box-fan at Window B, facing into the house, and another at WIndow E, facing outside -- with only those two windows open.  I was hoping this would create a mild wind-tunnel effect, sending a cool breeze through the house.  My second thought was to open all five windows (A, B, C, D, E), placing the fans in the same place (B, E), both pointing inward, sending all the air into the living room and -- my hope, anyway -- out Windows C and D.  Another wind tunnel effect.

Do you see any better placement ideas?

Given:  Windows A, B, C, D, and E can be open or closed in any combination necessary.  Archways G and H have no doors on them -- they are just entryways.  Doorway F can be open or shut.  Doorway I, I would prefer to be open at all times, because the restroom has no ventilation.  And Doorway J I would prefer to be closed, as there is no screen on it, and many monsterous bugs and wasps hang around outside.

So, what do you see as being my best chance of keeping my little house cool?
