Technically, pure water is not a good conductor.  More of a dielectric 
insulator.   Its when you get those nasty impurities and ions in it, 
that it becomes an ok conductor.  Since its such a good solvent, its 
rather hard to keep those nasty ions out.

As far as I remember, one of the hardest parts of dealing with cooling 
liquids are the impurity buildup issues.  Unless you are dealing with 
Flourinert (see www.sisweb.com/referenc/msds/fc70.pdf ) which is 
goodness embodied ... unless you burn it ... then its pure eeeevuuulll.
