Far as what I remember... its not noise but SMIC duct behind the fans.... which puts restriction on the flow and require harder pull (4 blade fan). In 99+ mazda put 7 blade fan vs. 4 blade fan in 93-98..
Is you are going with FMIC (like me), go with 2 x 4 blade fans as you no longer have duct behind the fan and also want maximum flow.
