Thanks, Ian. I think my original question has been answered. I was 
thinking of a typical heat sink as a heat transfer device rather than 
a cooling device since it's ability to cool is quite limited unless 
it in turn is cooled by air, liquid or radiation. A matter of 
semantics to some extent, but the point is taken.
