For some of us over-the-edge pc enthusiasts, we use a non-conductive heat
transfer fluid for 'water-cooling' our over-clocked cpus:

http://www.dangerden.com/store/home.php?cat=63. If you buy it in gallons,
I'm sure you'll get a better price.  If I recall, conductivity is somewhat
less than water, but still good enough to do the job.  I have a solution in
place that has been running continuously for two or three years now.  By
distributing the heat to larger slower fans, my room is quieter.   If I was
really inclined, I could put the fans out my window and have practically
dead silence, if it wasn't for the power supply fan.

 Another poster mentioned dripless quick-disconnects.  They do exist.
