Also, how old is the radiator? Was it flow tested, or just flushed? Overheating at highway speeds is a sure sign of a plugged radiator, and flushing it out won't normally help. You have to have it flow tested by a radiator shop to tell for sure. You get plenty of air flow through the radiator at highway speeds, so the fan should not be the issue.
