This reminds me of the old Cray-2 super computer.  The entire machine

about a half dozen racks were flooded with Fluorinert.  This is a

coolant made by 3M.  It looks like water but is inert.  It's a

fluorocarbon.     Cray placed a 1980's vintage mainframe computer in

was was basically an aquarium full of the fluorinert and then pumped

the  fluorinert through heat exchanger that used chilled water.  Cray

place windows on the computer to show off the liquid emersion cooling

system and some places had little plastic toy fish in their tanks.
