Take a good look at your fan clutch, you may have replaced it but "their not all created equal".
I would think that the mechanical fan would be most helpful in city driving and if my clutch was indeed going bad it would be evident with my electric fan having to kick on while idling/city driving. I will take a look at it but even if it wasnt working 100%, with the airflow I "should" be getting on the highway it shouldnt make a difference.
Not sure about next steps, maybe a compression test, a thermostat swap (just in case it does not actually fully open enough for highway demand), and an IR gun to monitor temperatures (lower vs upper radiator hose, thermostat housing, front vs back of head, etc...).
