Oh, we like digressions :-)

I recall that sometimes last year, Tom's Hardware tested running a system
without heat sink... but completely immersed in... cooking oil! They made a
large acrylic container, poured in gallons of high-quality cooking oil,
then proceeded to overclock the CPU and GPU to unholy frequencies...

And, IIRC, Seymour Cray likes to use some inert fluoride-based coolant to
dunk the components of his supercomputer machines. And he would even go to
lengths to design a "coolant fountain" that's not only functional, but also
decorative.

That's the only qualms I have Re: water-coolant. I always an afraid of
leaks. So, I always wimped out and use the thermal wick kind of almost, but
not quite, somewhat similar to liquid coolant ;-)
