Well, in the old days, there were very few (I can think of one
Honeywell system) that used water cooling directly (i.e. direct
contact with heatsinks). The CDC gear used it in the condenser coils
located in the base of the CPU cabinet cooling unit. it made sense--
why ask the field engineers to run freon lines in addition to cables?
The freon was used to cool "cold plates"; i.e., cooling was not done
with air.
How do your water-fed server racks do their cooling? Air or cold-
plate or something else?
