Is it safe if I have my i7 8700k @5.0GHz with a voltage of around 1.4-1.45

I was wondering how long my Cpu would last if I have it @5.0GHz not delidded and with a voltage of 1.4-1.45? Thanks.

1.4 really is the max if you want to keep your CPU for a long time. 1.45v there is a risk of quicker degradation.

Also, since you are not delidding, 1.4 really is the max unless you have a really really powerful cooling system. 1.45 basically requires the best of the best AIOs or a good custom loop.

Well for cooling I have a Corsair Hydro h115i AIO should that be enough for it?

That's very high. You should reach 5.0GHz with 1.30-1.35v.
Did you update the BIOS and enable LLC on level 4-5 (50%) (Load Line Calibration)? What about disabling power saving?

Anything above 1.40v will start degrading the CPU. Also, keep your daily max temp to below 75c or below 85c on torture test.

For 1.40v the h115i should be fine, for 1.45v you'd need at least a 360mm rad. Again, since you are NOT delidding.

Ok if so roughly how long will my CPU last at 5GHz with 1.4v?

This is a bad idea. You should be able to go lower voltage than that. At 1.4v it will fluctuate both up and down a tiny bit. At any voltage it will. Keeping your voltage there will degrade your cpu over time. Also at 1.45v you need to be running a custom loop and delid the cpu. A regular 360 aio is not going to get the job done.

Find a nice spot that is lower and balance it with LLC.
