Would be very inefficient/bad idea. The idea is to have air FLOW. The more air flows across the fins, the cooler it can go. To a point. By forcing air in from both directions you won't have flow, and it will be worse then if you did. (Try it and see.) You usually want hot air going out, so point the fans so that they air flows from case, to rad, to outside case. If doing push/pull like you showed, one of those sets of fans needs to be reversed.

Mine is definitely a push/pull config. But not like that, I was just wonderiing what would happen lol. My config is both fans sucking the heat out of the case.

Seeing as you have the parts, try it and see. And report back of course. You never know when you might stumble onto something. Always worth a shot.
