Skyco-

I thought the same thing and I am with you 100% - the lower volume might also help not "cook" the sap driving it (me) also. I don't have any experience with electric automotive fans, anyone know if they will run backwards? Many of them say "Reversible" but I don't know whether they are talking electrically or how they are physically mounted.
