CPU Damge: Heat or Voltage increases causing Heat?
don't worrie about degrading or damaging a cpu unless you are a idiot its practically impossible
if you run insane amounts of voltage for extended periods you might manage to degrade it enough to where the overclock isn't stable anymore
but saying heat is just a by-product of voltage is wholly incorrect there are many of factors at play a example that as the temperature climbs the resistance,impeadence,switching ablity and the leakage of the transistors can change eventually you can get it hot enough to cause a internal short of sorts leading to a cascade effect causing damage remember you are working on nano-meter scale so a 0.05% change in the circuit from thermal expansion can be a real problem at those scales
other things to consider are
1. the inherent capacitance of transistors of that scale
2. gate time and the amount of leakage around a fet-type transistor when it is closed
3. circuit load and current handling capacity at a given switching speed as you go up in speed you lose regulation ability to to ~float~ again you are talking about very very small scales here
4. plain old fashion to many AMP's and not enough pathway
and yes if you can keep it COLD that drastically changes how much voltage you can run
cold causes things to contract witch at the nano-scale means path-ways become tighter and less leaky allowing you to pump more voltage to drive the transistors there is still a finite limit
