Is the safe voltage ceiling reachable with air cooling?

[thehidecheck]

I'm on the fence about getting an LC setup if all it can offer me is lower noise level's and possible a better aesthetic. What I want to know is, in the perfect air cooled rig, running all high rpm fans at 12volts, loud as all hell, can it reach this particular performance ceiling; this point being where the voltages(or the temps) are not degrading the processor to the degree that it will have to be replaced every(lets say) 4(ish) years? This question extends to gpu's aswell(let's only consider up to two cards sli/crossfire with adequate spacing).

I envision a system like the silverstone fortress 2 with high rpm fans, a d14 with a third fan, and 2 gpu's with triple blowers. For arguments sake, lets just say the cpu is a 2600k and the gpu's are gtx580's.

If you don't think this is possible, do you imagine it soon will be with the lower tdp's we are seeing with like ivy bridge?

you can hit a ceiling with air no doubt look in my sig at my 2600K validation that is with a d-14 5.3GHz at like 1.65+ vcore. Now one would never run it there for 24/7 if thats what your asking. The thermal/voltage ceiling for 24/7 use is obtainable air or water. I run 4.5GHz at 1.36 Vcore for 24/7 most will say 1.4 is the most you want to go. One member here did that and folded with it for like 10 days and now it wont keep it where ha was. So the true degrading point is different per cpu. besides there comes a point of diminishing return where no amount of extra MHz makes any difference.

As far as IB is concerned its hard to say at this point as they are not released yet. But while its made on a smaller platform its still made the same fashion with silicon and circuitry, so I'd wager to say no even with lower TDP there is still a breaking point.

With a 2600k you will probably reach the "realistic" max the chip out before needing silly voltage bumps for just an extra 100mhz, and in a good case dual gpu's wouldnt make much difference, so yes on a 1155 system it would be possible imo, if you had said a 1366 i7 setup then things would be a little different but you would manage a good clock non the less.

Danky kindly for the thoughtful responses. If I would have tried asking something like this at tomshardware, I wouldn't have gotten anything useful(or at least answers with this much consideration).
