Is it the actually VOLTS that kills a processor..

or is it just the additional heat that is created due to a voltage increase. Old processors use some ridiculous voltages and still are functional today because they were decently cooled, so I'm sorta leaning toward the heat being the issue, not the voltage!

I might do an experiment:
Get two processors identical (or close) batch. Build two systems that are identical, and make one overclocked with a high voltage and water cooled and another at stock voltages , and see which one craps up first .

Voltage.

its a combination of both. with the extra added voltage more heat is generated. but to much voltage causes electro migration and that is what kills chips but it killes them slowly

overvoltage is the main problem...

if a processor goes above their max temp... they will shut down automatically, so unless you continually do that, or run it constantly at high temps, it won't kill the processor

voltage on the otherhand, can outright fry a processor... if you set too high of a voltage, and turn your computer on, your chip's gone..

what's with the white text underneath? But yes, voltage kills the CPU

Older procs could handle and needed higher volts because of the manufacturing process used... We are now getting into 45nm and soon smaller which are effected by electromigration much more. I few atoms in a wall plug moving don't really matter. but in a connection much smaller they are a much larger percentage of its total mass. Why it is a combination of the two i believe is because heat speeds up the electromigration process... at least that's what i have picked up from reading here.

Yeah, the smaller the electrical pathways, the less voltage it takes to run the processor, and the less it takes to fry it.
