overheating!!

what does the rest of the system consist of? the worlds best radiator can only do so much if the fan/fans are not up to the task. if you are running a mech. fan does it have a shroud? if electric what are the flow ratings?

also what thermostat are you running? is it a high flow unit? is the system running full of water with all air burped from the system? it all works together.
