The lines do run across in that area and one would think that the rushing air past them does help cool them. I might be odd ball thinking here but it might be true that it helps.

Or maybe the factory cooler itself is semi plugged, it should stay near the coolant temp when you arent in traffic. I remember going about 240 miles without stopping and never saw over like 180.
Can you explain more about the duct work? Also, how would I check if the factory cooler is semi plugged?
