Keeping this debate on the anecdotal experience level, I have never had an overclocked cpu fail, simply because you notice that it gets too unstable long before it suffers catastrophic physical damage. So, I would assume there are two probable causes when an overclocked cpu dies: It was left unattended for a very long time, so the overheating was not witnessed, or the fan failed, maybe even while you were at lunch. I knew of one to die while the guy was on vacation, because his co-workers needed access to his files and evey time it locked up they would power it down for an hour or so. None of them realized why that worked, they were just treating the symptom. Three days later, and after dozens of power on cycles, the cpu failed. Turns out the cpu fan was running at about half speed from worn bearings. My rules are: install good cooling, regularly inspect the cooling and keep it well maintained, and turn the PC off when you leave. Of course a regularly clocked cpu can fail under similar circumstances, so my view is that the risk isn't significantly different for an overclocked cpu.
