Basically, what I am saying is that, because copper is sufficient to absorb the heat from a heatsink (it certainly if if SS is - it's heat capacity is only slightly lower), then what we want is the highest conductivity to get the heat away from the diode quickly. Of course it will fit up faster, but that's not our concern. We're okay with a filled heatsink, as long as its the diode that fills up last (i.e. there will be a traffic jam near the door BEFORE a traffic jam near the room/hallway entrance). However, if more people are trying to go into the steel hallway than they can exit (i.e. if its not wide enough to hold everyone), then we will have a traffic jam near the fire (diode) and the heatsink won't be doing its job.
Yes! AND on top of that, even though radiant heating to the air isn't necessarily the most important aspect of our sinking - with copper's very high thermal conductivity it actually gets those "people" to the exit door where they CAN leave the building.
