Anyone have an electric fan between the rad and AC condensor?

I'd like to sandwich a supplemental electric pusher fan in between the radiator and my AC condensor. That'd keep it reasonably well hidden and is the best location for it to move air too... but there's just not a lot of room, only a couple of inches.

I figured if someone already had one in that location, I'd know for sure what fits.

Anyone have one? Doesn't have to be enormous, it's just for hot idle when things start to climb in traffic (cools fine when moving).
