The fan sits about half way in the shroud, which I believe is the correct depth. After reading your response, I'm thinking that the clutch may not be getting full engagement because I don't really hear much fan noise when the car is at temp. I understand that 210-220 is not that bad for these cars, but the issue is keeping it at that temp. It will continue to get hotter than that while idling quickly getting up to 225 or 230.
