the beauty of this is, your imagination is the limit to how fancy a thing you want to make.... well ok almost..
but as one can see... virtually any shape can be made and the planes in which the fans sit towards the radiator can be adjusted just as easy...
this one was particularly difficult, due to the large fan and relatively narrow radiator flange, nun the less it came out really nice, and oh the silence from a 120mil on 7 volt and 3ยบ down on nominal temp... I'd call that a couple o hours well wasted.
