No molten insulation or something like that.

Usually, there's some kind of visible trace.
The plastic insulation starts to deform under the heat, and eventually exposes a bare wire. If it's hot enough, it'll burn the insulation.
On the other hand, if the cables sit perfectly straight, the insulation will only shrink a little bit around them. The problem is that over time, it will become hard and brittle, and eventually flake off. The bigger issue though, is that it can melt the solder right off of the PCB, which can in turn create an open circuit.
You don't want to know what happens when all the power lines are ok, but one fails.
