I only have a 2 core but their 1" cores so I think it might be real close to the same thickness of yours. When I first put the radiator in I put one big electric fan on it that nearly covered the radiator and it had to be a thin line fan. Your 2 fans will give you a little more room since their thick part (where the motor is) is offset from the water pump.
BTW: in the end I took the big electric fan off cause it was still running hotter than I liked and I put on a viscous fan and it cools better than the big electric fan. Your experience may not be the same, just sharing mine.
