4.5Ghz Overclock A Good Idea?

I've overclocked my Intel i5 3570 (non-k) CPU to 4.4Ghz and finally got it stable yesterday (thought it was stable for ages until one game told me otherwise), after I raised the voltage a bit more. I want to try to push to 4.5Ghz but I'm not completely sure if that's a good idea. I used the Intel Extreme Tuning Utility to push my CPU past 4Ghz, as it had problems going past 4Ghz even though the turbo boost is only like 3.8Ghz. I raised the BCLK multipliers in the BIOS to 42, 41, 41 and 40, and raised the CPU clock from 100 to 105(it says 104.9897 in Intel ETU), giving me a clock speed of 4.41Ghz.

I raised the voltage by +50mV from stock which was necessary to stop my computer from having problems at 4.4Ghz (had to raise it from +35mV even after Prime95 and Intel Burn Test passed, with my monitor black screening and sound looping after 25 mins of Saints Row 3, when there were no problems with no other games). My temps are 67 degrees max with Intel Burn Test and mid-high 50s while gaming.

Is it a good idea to push the voltage more so that I may be able to raise the CPU clock past 105 and achieve a 4.5Ghz (or more) overclock or what?
 
How did manage that with non-k series CPU. Don't take too much risk with overclocking the chip which has no potential for overclocking. You may have severely reduces the life of the CPU without even knowing it. Better stick with max turbo or grab k series CPU for overclocking.

I can't grab an Intel i5 3570K as Ivy Bridge is no longer sold where I am (Australia). I just told you how I managed to overclock it (enabled non-K overclocking in BIOS, changed BCLK, modified voltage by +50mV, or 0.050mV or whatever, in Intel ETU). Temperatures are only 67 degrees after stress testing and 55-57ish while gaming and doing basically anything else, and lifespan of CPU only significantly decreases after significant heat/voltage when the typical CPU lasts over 10 years (I think?). I'm going to replace the CPU after 3-4 years anyways so I'm just wondering if it's safe to up the voltage seeing as temps are in a safe range.

I think I'll just wait a few years as I only just built this PC 6 months ago and the gains between Ivy Bridge and Broadwell ,if it supports LGA1150, are only 10-15% in real world and even less in gaming.

I asked only about overclocking. I have no wish to spend money on new computer components.
 


Good point. Just overclock your CPU to max turbo at the moment otherwise its life time would reduce and generally, this is not wanted.
