Actually I'm right. When you place your finger against the plastic
section of a transistor or IC which is on a heat sink the
temperature usually feels cooler the heat sink.
You can't place your finger on the rear (often metal) side which is
against the heat sink (and may be much hotter).
But the heat sink is often hot enough to burn your finger (and
often the device is definitely NOT). Now maybe the plastic just
doesn't transfer the heat to your finger very well. I'm don't care
about science at this point, only what I see or feel.
