ya might run into a little problem with the fan the close to the radiator. fans tend to flex forward at high rpm and could get into that radiator. you might want to go with 1" minimum clearance to be safe.
My setup is factory original and there is barely enough space to get a fan belt between the fan and radiator. Never had a blade touch the radiator, but it is the factory rigid fan blade - not the flex fan (which should flex even further away from the radiator under high RPMs). Just saying. Good luck and I hope your problems have been solved by now!
