If you overclock CPU, you lose warranty. Even if it's K-series which is made for overclocking. And stock settings probably are safe.

Yeah I did mean at stock settings.
If you overclock, you're responsible. Losing warranty sounds acceptable to me. Better than manufacturers doing everything to make overclocking impossible.
To me, it's a great way to get more performance out of an old chip, the warranty would be expired at that point.
It is hard to prove a CPU was overclocked though, so I can see some people taking advantage of that.
This is like the cooling argument all over again - "your cooling system is good enough for normal workloads". No, it must be good enough for permanent full load! Like a CPU under Prime95. If your heatsink lets it overheat, it's defective. You saved a few pennies on the copper and now it's a defective product.
Same for Prime95, the CPU must be able to run it for days at end and last ~5 years. Doesn't seem like too much to ask for, imo. Intel says their chips will run at 98 degrees for years, so why would a full load like Prime95 kill them in days?
One other thing, overclocking these days is actually undervolting combined with raising clocks. The old school "just raise the voltage" is a bad way to do it on any Intel chips post-Sandy Bridge...
