I'm confused about why a processor's life span is reduced by overclocking when the cpu is kept cool? What else is going on that will reduce the lifespan of the processor?

higher voltage, higher frequency, for instance. if keeping the chips cool would mean a longer lifespan, then those guys who OC under LN2 would never see one of their chips die.

I guess the bigger question is then, if I OC and everything is kept cool, will my cpu last long enough until it is obviously time to upgrade the computer? Say 4 years?

BTW, what is LN2?

If you won't OC your chip to its maximum and keep it running 24/7 on high volts and high temps it is probable that it will last a few years

LN2 is liquid nitrogen, a very cold stuff

But this is not exact science you know, it rally depends on all your hardware. Let's say you OC your current CPU, the one one your sig Q9300. It runs at 2.5Ghz stock, 333MHz*7.5. taking it to 3GHz, 400*7.5, with that board and RAM wouldn't be risking that much imo, as the board can handle the OC, and with a FSB/RAM ratio of 1:1 you wouldn't be OCeing your RAM (400*2 for 800MHz). For making it reach the 400FSB, you would need to increasi the voltage a little, say to 1.45V, what would mean that max temps on load would easily reach 80-85ºC on low-budget air coolers. If you cool it down on water, with a Corsair H70 for instance, max temps on load would decrease to 60-65ºC perhaps, maybe more, and so you wouldn't be damaging your chip so much. however, with 400FSB and 1.45V you will be reducing the chips lifespan significantly, and your board as well. Keeping it cool will help on making it last, but volts will kill it much more fast than temperature. Also, it is likely that your board starts failing sooner than your CPU, or maybe not...
this is all theoretical, as it depends much on the chips too. If i had a Q9300, mine could last longer at 3GHZ than yours, or the other way around... you see?

Thanks for the explanation matroska...though to be honest, it was way over my head. I have yet to OC a cpu but plan on doing so before too long. Once I do, I will have tons of questions and hopefully in doing so, will learn more about my cpu and how it works.

Ok so liquid nitrogen. Can you explain the difficulties of doing it? I have a friend that wants too. and i kinda beat him down for it. cause from what i have heard. U constantly have to feed it LN2. And that stuff just flat out isn't cheap.
Also. I wondered if you can control the fan speed on your CPU cooler. Is there a program that will take control of it so i can run my PC cooler? Also, is there anything i can get to make sure that i have control over the H70 when i put it on. Like how fast the pump runs and etc?

i was never into LN2/Phase Change, so i don't know much about it...LN2 is not a cheap cooling solution, and it isn't as easy to set up like a regular cooler, that i know

you can browse the Phase Change / LN2 are of the forum following this link: http://www.overclock.net/dry-ice-liquid-nitrogen/

OK. So say for instance. i just wanted to Over clock a little just to give it the boost i would require or need. Can i set a little amount of O.C.? Like say maybe perhaps about .4 G Hz increase? Then i get better performance, and save some life expectancy. I also have been looking around for a board. Its going like garbage. I saw some ASUS Rampage board with the P45 on it. But i didn't go for them. So idk. I need to locate a board that won't overclock a ton but just enough so i have that extra kick to the CPU. Let me know back. Also, can i cool my motherboard. Get some of those fans that are screwed into the case with the motherboard and have a bunch of fans cooling certain places of the board? If so, can you let me know which places need a fan. I assume that south and north bridge. If any place else. Lemme know.
