But there are several different sizes type1 fans! The Doghouse style fan from
1971-upwards is bigger but I cannot remember how much air it moves. It could be
something like 540 liters per minute @ 4500 rpm vs. 450 liters on the older
non-doghouse style.  I'm not sure whether these rpms are fan rpms or crank rpms,
the book didnt say.
