I think that people with AIO System and Air cooler should keep on Max 1.300V without some voltage spikes under load.
What CPU can with that voltage that's it. 4.3 or 4.6 over that I think it's not safe and up to 1.350V for good watercooling where temps no matter on load stay under 60C.
If someone want to CPU work nice for 5 years.
Example I have i7-3770K capable to work on 4.5GHz on below or max 1.200V. Problem was because I had such motherboard where it was not possible to drop CPU Voltage or CPU Clock. Overclock on max speed or not overclocked with Turbo. After 3 years and little more 24/7 constant 1.200V and constant 4.5GHz in idle CPU didn't show any sign of degradation and need absolutely same voltage for overclocking and that's about 1.300V for Prime95 AVX Stable on 4.8GHz. But I kept for every day only 50mV over fabric voltage. Because even after 15h Prime95 I didn't recognize that I will get benefits from 4.8GHz instead 4.5GHz... Even if Prime95 AVX stable so long time is much better prove that CPU will stay stable in normal applications and gaming than any of now attractive tests.
For 1.4V I'm not sure how much Haswell E could behave on 2-3 years period. That's 250mV over fabric voltage.
On short time probably nothing, but on longer period I don't know... Skylake maybe is even safe on 1.4V.
