That's wierd.. Never gave me any trouble. Well, let's put it this way; as long as the voltage is at least the rated value (according to CPU-z) or a little bit higher, it'll be safe.
You do get non-conductive liquids specially for liquid cooled PC setups... My internet is messing around at the moment, so I can't load the actual page, but a quick Google search showed a couple links that look promising; such as Non-Conductive Coolant and PC ICE Non-Conductive Water Cooling Coolant 32 Ounces CLEAR: CrazyPC Computers.
Oh, and if water (or non-water based) running through pipes isn't quite hardcore enough for you..... Why not submerge your entire PC in oil...? Hehe... Custom PCs by Puget Systems; Mineral Oil Submerged Computer
First one listed from Google search:
PrimoChill ICE Non-Conductive Liquid Cooling Fluid
Feser Aqua
3M Performance Fluid
Several to choose from, non conductive water cooling
