That's not entirely true. There are objects in motion mostly electrons. It's more of a breakdown in the di-electric compounds that allow leakage of voltage, but I digress. Can you tell I used to be a EE
In answer to the OP I've been overclocking several systems for several years, and most of my loads turninto source distros. I have yet to kill a proc from working it. Other deaths are mostly due to my stupidity, overvolts, shorts, etc. The actual lifespan of a cpu is more on the order of 10-12 years at speeds and usage in the design parameters. I've heard several differing theories on this. Some say that working the IC hard WILL shorten the life of the device but only by a few percentage points. It will have long since been obsoleted before you will get to that state. I'll stop rambling now.
