Paul; Can you not overclock safely for heat reasons by using active or extra coolling to keep the actual die temperature within spec, or within an allowable excess?. This was commonly used years ago. I suspect that if the faster speed makes some timing spec get exceeded that this would be the actual limit.
In effect both overheat and running out of timing specs are two ways the chip can fail to operate at a higher speed, and only the heat can be palliated to some degree.

Can the timing be helped by slight over voltage to make transitions harder?, this would worsen the heating, but by judging the two you could run both at the limit. What would that limit be?

What are other things that go wrong if you try to run faster?(apart from external failures)
