Agree. can run too cool, especially in a ******. 230 is a fine temp. Still really love the T-bird/Mark fans.
I'm running the 15" version of that fan on my coupe. It moves a lot of air at rpm but it ain't helping me at ide. My radiator sits behind a 4" chopped 32 grille and the core is only 15" X 17". Engine is a 9.7:1 351C and it will hit 230 in no time at idle. Runs 195 at speed though. I'm about to try out an electric fan to help with the idle issue.
