most chips will hard lock and crash before reaching a temp that will instantly harm a CPU. most temperature damage is caused by long periods of time at relatively "low" high temperatures.

voltage can kill a chip far quicker than temperature ever can think of.

there aren't hard lines in overclocking either. 1.45 doesn't mean 1.44 is safe and 1.46 isn't -- it just means most chips tested fail at 1.45v. you might be killing your CPU slowly while running 1.42v while Bob isn't hurting a thing running 1.45v on the same model number CPU.

if your goals for OCing is "don't shorten the lifespan" than you're just fooling yourself unless you're not overvolting/you're undervolting.

What is ivy's max? The only thing i can find is intel's listed tcase max, of 67c

How safe to run it say 1.45 for 24/7 with say 85C MAX ????

Running @ 85C is foolish.

Tell that to my 920 that has been running 85-92C for going on 3 years, folding 24/7. While not recommended, they have a throttle mechanism for a reason. I like to keep mine below 80C for my 920 and 2600K, but running it over isn't exactly what I would call foolish either. They are made to withstand 85+ temps for long periods.

105C

i remember my i7 930 hit over 100c (maxed out the sensor) for a few seconds before restarting. lol i forgot to plug in the pump

i had to change out the tubing because it basically melted it a little.
the first gen i7 were built like a tank.

honestly i try to upgrade every 4 years depending. but my old i7 930 seems perfect for the next 6 years.
i cant imaging using my E8400 today even at 4ghz its not enough.

thinking about selling everything later and going to Haswell when it comes out. and sticking with that for another 4 years.

Keep in mind that those maximum temp ratings are for stock speeds and volts. The more current (clock speed) or voltage you apply, the colder the chip has to be to last the same length of time.

but good question what is length of time for stock speeds and volts

if I can get 4-5 years at 1.45 on 5Hz+ its more than enough
