Default Re: factory fan cfm

cooling is only effective if you can get the balance between air flow and coolant flow correct . since an electric fan runs at a set speed there is no increase in cfm as engine speed/load increases so you need to start towards the high end of air flow requirements and guess what all fans are not equal .Fans of the same size can have a difference of over 100% in airflow
