So is the 7-blade fan with a thermal clutch the ultimate solution for the best cooling (with A/C)? Although I understand how it works mechanically, guess I am not totally sure how the fan clutch affects the cooling. When the clutch heats up, the fan turns slower, right? So is the idea that too much airflow is a bad thing? I really want to thank everyone to some great replies to my post. PS: BBob, that's a good looking engine - is that in your ride now?
