I'm curious why the aluminum radiator performs better than the copper.
I suspect it must have to do with improved physical design.  Because
copper has a significant advantage (roughly a factor of 2) over
aluminum in heat conductivity.  That means that for identical physical
dimensions, copper will conduct about twice the amount of heat that
aluminum will in the same period of time.  //Jack
