Do let us know how this works! I replaced the stock fan with one of them
shiny silver Volterras the last time I was behind mine. I studied the
idea of shrouding the fins to build a "wind tunnel" and funnel that air
through the fins. Looked complicated. But I guess that just using some
bubble wrap or even heavy aluminum foil would work.
