Cpu lifespan ?

[The321]

How do temperature's affect lifespan? I mean like in 10 degrees extra is like half lifespan . Anybody has an answer like this ?

If you are constantly riding the thermal throttle limit, it can affect lifespan. If you are talking 50c vs 60 or 60c vs 70c, then no the difference would be negligible.

there is no set in stone number of how long something will last, regardless of temps, as there's so many other factors that could kill a cpu

Constant high temps (greater than 90-100C) would shorten the lifespan only by a bit as there are safeguards in place. Most CPU's that I've dealt with have been killed by extreme voltage spikes and a mainboard malfunction. 

 

I think Intel's Prescott family (could be wrong) had an errata that was fixed concerning a certain instruction set going full-tilt even past any safeguards causing untimely death for those users.

From personal experience a CPU that is keeping higher temps has higher chance of killing the motherboard than itself. Don't overclock and overvolt if you don't need to do it. As a result of me f*cking around with it I destroyed motherboard power phases, yet the CPU is still ocing to over +1.2 GHz above stock....
