@Thelegend: but, if you only increase the fsb without increasing the voltage, is the lifespan also decreased?
LE: also, could you explain why do you need to increase the voltage in order to keep an oced cpu stable?

DuckieHo

Yes, because you are pushing more signals per second. Your pushing your processor harder. Heat will increase and lifetime will decrease a bit.

Also I would assume that no cooling solution so far can keep 'all' of the core cool. Like it is like a cube, we're cooling just the top, it will still have heat at the bottom that needs to transfer through the core. So even high end cooling on the one end still can't keep the heat down on the other end as well and where the higher voltage can affect it and shorten the lifespan (Not a huge issue but is what I assume could limit extreme cooling overclocking).

Extreme cooling actually freezes the entire socket, top and bottom. They actually need to use heat elements to keep everything from freezing. If you can absorb the heat fast enough, you can chill everything. At the atomic level, electromigration can still occurs. Temperature is just the AVERAGE measurement of atomic movement.

Awww, I was going to bring that up. But anyway, when electrons travel through a CPU they are forced to travel a set path, but they want to go to the nearest positive ion, according to the laws of nature. They "bump into" the silicon, eating away at it, and the faster the velocity of the electrons the more gets broken off each time. Velocity has little or nothing to do with CPU speed, the velocity increases with voltage (a measure of the velocity of electrons) and heat (the hotter the temperatures the more excitable the particles, and the faster the electrons move). Therefore, a chip will eventually die when the electrons have "scraped" off enough of the chip so that they do not travel in their designated paths anymore, a.k.a go into other electrons' paths and cause computation errors. Do note that heat can also not only increase the velocity of electrons but also physically melt the plastic, two of which are totally different things happening, although they are both caused by excessive heat and both kill a chip. Also note that they don't really "scrape" or any of the other verbs I used having to do with electrons, they only do this figuratively.
