Most likely lack of air flow.  This is common wiht a re-cored 
radiator where they used a core with too many fins too close 
together, so it restricts air flow at road speed.  For that you need 
a really large fan, or an electric fan to assist the air 
push.  Better to get back to an original type radiator with more air 
flow capacity.

Other possible causes may be a loose fan belt (slippage reducing fan 
speed), or a loose or missing impellor on the weter pump, or a 
clogged radiator core restricting water flow.  Possibly a faulty 
thermostat that does not open all the way.
