I'd say it would reduce the life, but it would be a fairly insignificant fraction UNLESS you also bump the voltages up.

According to the follwing, CPU's failure increase is a direct function of the number of thermal cycles and the change in temperature above ambient. So in addition to heat, turning the computer on and off also reduces CPU life.

It will be severely outdated even long before it would eventually cease working. I've not seen a CPU croak either, unless it was overclocked and overvolted beyond even the extreme limits as mentioned earlier.

I have a Pentium III 700 MHz running at 933 MHz and 1.75V (default voltage is 1.65V) and it's still running fine in my fileserver 7.5 years after I built that rig.

Yup. I also soldered resistors on Slot-A Athlons because the "goldfingers" devices looked too cumbersome.

too much voltage and/or too much heat will decrease the life of your processor.

dont overvolt it and keep it cool and you will be fine

Yup, turn it off, the silicon gets cold and contracts. Turn it on, the silicon gets warm and expands, and this causes the silicon to fatigue, eventually. This is why I was always in the "Leave it On" camp, but man, I just let my computer go into standby mode after an hour anyway because I don't like paying the electric bill.

That is a very good read. So theoretically if you could keep the temps lower an OC'ed processor with a high end cooler could last longer than a stock processor on a stock cooler.

also another reason to keep SpeedStep and Cool N Quiet enabled.

As everyone above has said, voltage and temperature increases will decrease the life of your processor. How much is the unknown.

As long as you're keeping it cool and you're not amping the voltage it should last way beyond the time you'll be using it.

No, you should have no problems with OCing.
However, there are still better fans, performing more silent as well. Just look at this comparison chart:

Exactly. Using SpeedStep, my Q6600 runs at only 2.0GHz while web browsing and such.

Default Re: Does overclocking reduce the life of your CPU?

I honestly dont think that OCing really will do anything cause if they didnt want you to OC then they would already OC them for you!

But on the other hand mine got messed up.

I bought my AMD x2 4200 socket:939 CPU in June 2006. I have a ASUS a8n-sli deluxe mobo which has a AI or NOS OC and ive had it on the AI, never NOS, 10% OC for a little over a year and now when if i have it at 10% OC and i try doing something that takes alot of CPU like converting or burning my CPU will go to max(100%) and freeze or blue screen. It took me a while to figure out why. And sure enough it was the AI that messed it up. Dont know how or why but i'm just going to end up sending it in since it still has a year left on the warrenty!

But i wish i could still OC cause it takes twice as long now to do ****. For all that are doing anything or even OCing, dont cheap out on a CPU, spend liek $60 a get a really good on or even a water cooled one. Cause i dont think you want to fry your $300 + - CPU!

I have this CPU cooler which the metal never really gets hot:
