i know there is non conductive water which if it gets on something shouldnt
conduct electricity but how safe is a water cooled system?

If you put something hot into a liquid, you have to worry about forming a film
of vapor that keeps the liquid from touching the hot thing, and radically
reduces the heat transfer. It's all tied up with the turbulence in the liquid,
the surface tension of the liquid, etc.
Boiling is a really g

If you used oil, you could build something smaller (at least if you
don't count the tank). The 2nd cluster gets sufficient cooling from the
natural convection which develops in the channel (no forced convection).
The same would hold for water. It would be fun to try, but I think air
is more c
filming in what sense with the heat though i thought that the heat would
prevent the oil from congealing?

For electronics cooling..
Mineral oil, usually with a oxidation inhibitor. Shell Diala AX is what I use.
For HV, dry and clean is important.
If your hardware isn't oil compatible, then a variety of silicones (e.g.
Fluorinert) are used (at substantially higher cost).
For really high power densit
john sry for the mis understanding in regards to the type of oil used i did
some searchign and i turned up alot of videos of people doing something
similar using mineral oil as the coolant.

In contrast to our "Second cluster" on that site, which is completely
fan less, this has two large fans. By using the fans one can get
