A larger heat sink will make the heat less apparent as it is better
distributed and dispersed, but the efficiency would still be the same. A
smaller object heated by the same amount of energy will be hotter.
The larger core would be more resistant to saturation, but if you are near the
point of saturation, then you really have other problems that need to be
dealt with.
