Hello! I have recently got the intel i5 4670k and am looking into overclocking however after some attempts, I'm unsure what I should do. These are my system specs:

CPU: Intel i5 4670k
Motherboard: MSI Mpower Max Z87
CPU cooler: Noctua NH-D14
GPU: MSI GTX 770
PSU: Corsair HX850
Case: CM storm trooper
RAM: 2x4GB Corsair Vengeance Pro 1600MHz

I am using the RAM at 1333MHz and 1.5V. At stock speeds and 100% load (using Aida64) the cores run at an avarage of around 50 C and 1.2V. I tried overclocking and got to 4.4GHz using 1.2V, then 4.5GHz using 1.25V. I then tried 4.6 but the voltage wasn't enough. At 4.5GHz it run at an avarage of around 60 C but momentarily reached 77 C. My question is, can I increase the voltage to something like 1.3V and still have a healthy system? Will it shorten my CPU's lifespan to an extent where I should worry about it (I'm planning on keeping this system for 5-7 years)?

Give it a try, if stable try lowering it a little at a time say from 1.3 to 1.29 then 1.28 etc, then can even go to tenths and hundreths like 1.28 is stable but 1.27 isn't, then try 1.279, down to 1.278, etc

Yeah, will probably do that but even if it's just over 1.25V, will it shorten the CPU's lifespan?

Not necessarily, a lot will depend on temps, it's the heat more than voltage that denigrates the CPU, have good cooling and your in good shape

Well that's good, temps shouldn't be a problem, not hitting too high yet. Should I care more about the average or the max temps?

Yep, just keep an eye on it

So say the average temps are something like 70 on 100% load but it has bursts of something like 90, is that ok?

Cool, will do some tweaking and stability testing and report back.
