Pusing Haswell to way-over 5Ghz with water (need maximum voltage recommendations)

So I am currently pricing up a build that will consist of:

2 x Watercool MO-RA3 420 Core LCs
1 x 4770k (already own)
1 x Asus Maximus VI Extreme

Along with other components, but this is not necessary since the only part that is a concern to me is how well the motherboard will perform with extremely high voltage, along with the CPU.

I will not be 'pussy footing around' with the volts, but do want a semi-clear idea of how high I can expect to push the voltage before the CPU will likely die on startup.

I suspect high voltages will degrade the CPU lifecycle. I don't care for this CPU to last anything longer than a single year, it'll be at 100% load for all that time, at 5.4GHz+ with many volts going through.

Please note:
- The radiators will be cooling multiple systems at once.
- The motherbord will be watercooled.
- The CPU is already delidded with the vice method. I will not use the IHS, the CPU waterblock will sit directly onto the die.
- I am sure you have gathered if you have read this far, this isn't for your average PC build. The CPU I was given/swapped for a graphics card I no longer used, I have no interest in the price I could recieve for a pre-owned modified CPU.


Any recommendations on voltages will be appreciated!
 
Solution
I've heard of 1.6 being the absolute safe limit. Because yours is not an average build, there isn't much data on what you can accomplish.


Thanks, you're pretty correct with how there won't be much data out there.. Guess I'm just going to hope that the CPU won't completely fry within the first week
