hi
Is it true that intel k cpus have relatively shorter lifespan than non k ones , despite having better quality and being overclockable ?
I know that when a cpu is overclocked ,the heat , over voltage, stress ,etc may affect the lifespan,but my question is about when both cpus work without being overclocked.
I read about it somewhere on the net .It mentioned that k series are frail because of having less maximum temperature versus non ks.
For example when we compare i5 6600 with 6600k the Maximum operating temperature is 71 °C vs 64 °C.

If the above statement is not true,Why non k cpus can stand more heat ?(it is a big advantage)

thanks

Overclocking does affect lifespan, even fi you end up at the same temperatures as the locked i5. A higher voltage is degrading lifespan but not at all noticeable. Both CPU's would last long enough so that upgrading when either are finally dead, then you would probable get a 50% IPC/single core performance increase. Infact, I don't know of any CPU's dying frequently, unless it's a defect, which usually shows within the first 6 months.

"Maximum operating temperature is 71 °C vs 64 °C."?

Where did you read that. That's not true at all. Are you sure you didn't confuse it with operating temperature?

The OP is getting tcase and tjunction mixed around. The intel sheet states the tcase for the 6600 is 71 °C and the tcase for the 6600k is 64 °C.


amd1361, read though this to get more info on cpu temp then you probably ever wanted to know.
*edit, I was dumb and forgot to link the thing I was telling you to read
http://www.tomshardware.com/forum/id-1800828/intel-temperature-guide.html

In brief, tcase isnt something you will be measuring. The Tjunction max temp on those CPU's is more at the 100°c.

Only shorter life if you OC the hell out of it with some high voltage. Otherwise it will last just as long. 10-15 years. Heck my work still have a P2 running a old server. We had two but one gave up the ghost not to long ago.

The lifespan of the the Intel "k" processors is affected when messing with overclock settings, changing the voltages will play a big part in the lifespan of the CPU, but at base clock without changing anything and having all the correct parts the "k" series shouldnt show any lifespan differences when compared to the non "k" (locked) versions of the CPU

The only reason I could think of that would make a CPU have a shorter life-span would be stress. If you overclock a "k" CPU too much and you push it too far, then it will crap out sooner than a CPU that hasn't been overclocked (aka. a non "k" CPU) So technically if you overclock and push the CPU then it will die quicker, but if you overclock normally and don't push the CPU it will be fine.

As long as OCing is done in a reasonable manner, i.e. in particular not overvolting drastically, the CPUs will suffer no real ill effects. I've still got a couple of Q6600 rigs in the family that have been OCed from the getgo (2007), the Q6600 was stock at 2.4 and have one running at 4 still the other is used as a home server/WS running at 3.6 24/7, so has pretty much run non-stop since 2007
