Agree on temps being to high hence the thread :).
50s with cold ran going over the rad. So pretty much best case and it didn't cool down to the 180 thermostat temp
Well like stated on your thread before your cooling system is too small.
If it will not cool down to the thermostat while driving down the highway - your radiator does not have a enough cooling capacity.
If it cools going down the highway but gets hot when you slow down or at idle - your fan is not moving enough air.
