Since updating to a full custom watercooling solution I have been experimenting with various settings to try and get the highest clock with a vcore that I think is still in the sensible range.

Currently I have settled on 4.8ghz @ 1.36 vcore under load. I did an 8 hour prime run (blend) and the temps maxed out at 56°. So temp wise I am happy. I know that over volting your cpu shortens its life expectancy but is it relatively safe to keep it at 1.36 24/7. Due to various issues all of the power management options in the bios C1E, EIST etc are switched off.

On MSI boards you don't get offset (running a P67 GD65 rev B3) so the only way to get vcore to lower when idle is to set voltage to auto and that yields crazy voltages when underload.
 
I generally settle at 1.38v for builds. I've run for my own use various 2500K and 2600K @ 5Ghz + and stuck to 1.45v on custom water. However those were on boards where you could have offsets so voltage varied depending on load, if its any help i do know a few of my ocs tend to run full voltage and power for months on end in their various work related duties, i think you'll be fine.
 
OCUK had a notice on their SandyBridge K series CPUs stating not to exceed 1.425v I believe they had some consultation with Intel before posting this figure so it's what I would go by. Given your excellent cooling I think you have scope to try pushing a bit further if you wanted.
 
I think its was 1.4V actually (for all cooling types) and 1.425V for watercooling, though 1.45V is what 8-pack said once (1.5V for one-off benchmarks).. :)
 
shame you cant enable c states to bring down the core volts at idle. would reduce much of the wear and tear.

e.g. mine is at ~0 volts when idle :P
