Not the most complete description but I take it there is an inflow and outflow pipe pair to the tank moving the Novec to an external radiator to exhaust heat and a second inflow and outflow pair to the condenser also to an external radiator?  Ah, found it.  One gallon offered for sale @ $379.95.

This is off topic but the Novec fluid doesn't get pumped anywhere. This video should explain it better. https://www.youtube.com/watch?v=a6ErbZtpL88

Back on topic. Bitmain, I'm ready to purchase more S5's. With the price of BTC creeping up I think it would be worthwhile.

See, I don't understand that.  If it's an enclosed system and the Novec evaporates off the ASICs dropping their temperature, that energy is in the Novec gas.  If it condenses within the enclosed container as it must or it's lost, that energy must be released.  The energy wouldn't leave the enclosed container and its temperature would build.  He says he might heat a driveway.  So, is taking the heat out via whatever fluid is circulating within the condenser enough to remove all the heat?
The fluid vapour is cooled by water.

And the cooled condensate dripping into the lower chamber with the boiling Novec is sufficient to keep the major volume of Novec from rising to a high temperature.  I see how the cool condenser would be sufficient without a running fan to condense the Novec.  My thought was that an additional cooling of the liquid would be needed.

So, say 4 boards of an S5 cooled in this way would need a minimum of how much Novec I wonder.
