ok so this is a unique topic which (oddly) has never been addressed before in the history of overclocking - or even in the history of internet for that matter - so googling this up is useless, and it's safe to assume that very very few people in the world know the correct answer to this conundrum
so this is the question
suppose we have 3 new & perfectly identical CPUs (for argument's sake, suppose it's an intel 4-core CPU, if that makes a difference)
1- first CPU : stock settings (non-overclocked, non-overvolted), cooled by the standard crappy stock intel heatsink-fan, and has an average idle temperature of 55°C
2- second CPU : heavily overclocked (say by 50%), heavily overvolted, BUT also cooled by a state-of-the-art space-age cooling system so that despite the overclocking it has an average idle temperature of only 35°C
3- third CPU: under-clocked, under-volted, cooled by standard intel cooler, and has an average idle temperature of 35°C (so same temp as the #2 overclocked one: it's underclocked to compensate for the crappy cooling)
btw I mention idle temps but let's assume that there's the same differences in load temps (so CPU #2 & #3 have a -15°C lower average load temp than CPU #1)
question1: assuming they have the same total amount of activity & idle/load time,
which of these 3 CPUs will have a longer lifespan?
(or to reformulate: in which of these 2 CPUs will electro-migration occur first?)
question2: will CPU #2 & CPU #3 have the same lifespan?
PS. since this sort of problem has never been tackled before I reckon only an extremely highly qualified engineer/scientist would know the right answer to this, hoping some of them are on this forum, this question is addressed at them
btw I ask this in the intel section cause the general CPU section seems almost abandoned so unlikely many people will notice this topic
