On my stock air cooled Zotac GTX480 VRM's overheat if I push more than 1075mV and driver crashes,regardles of GPU speed..

I think that these cards do have some kind of a VRM heat protection that kicks in..

CHEERS..
I did notice when running over 1.2v that the card's gpu usage was spiking when I was folding.. Perhaps I'm safe then as long as temps are okay, which while on water should be pretty darn good.

What would you suggest for a 24/7 voltage on water cooling?

EDIT: Also, I just did a heaven run @ 960mhz w/ 1.175v, no issues. But I did have a little issue when nearing the 1.2v mark. I had to restart because it was stuck at 2d clocks/voltage.
My opinion is to keep it under 1.2V for 24/7 use, but I won't lie that I'm merely just conjecturing. Personally, I don't think it's worth the risk as you need quite a bit more voltage for a small increase in frequency, and it will only get more disproportionate the closer you get to the maximum capabilities of your card as a whole. Plus, 940 and 960MHz on the core is nothing to sneeze at either, as it stands.

But like I said before, if your benching stints are kept short and temps are under control, take it as far as you can reliably go to complete the benchmark. If you're going for world records, then that is a different story altogether, and would require more drastic cooling measures.
