Admittedly, I may not be as cautious as I should be about these things,
but it doesn't seem to me that the box would necessarily get
dangerously hot. When I was doing it, I left the box open, but as I
said, that was a VERY hot chip.
I've never heard of a "heat pipe", but that sounds quite nice.
I'm a little confused: is it a true pipe (i.e. with air inside) that
relies on convection? or is it something like a copper rod?
I must also say that the suggestions about controlling the
Peltier cooler are quite good. You can buy a ready-made device for
cheap.
