The LN2 cooled the chips by boiling, not by conducting away the heat. The resulting vapor was then recondensed and re-used (at all user sites) or just thrown away (at the manufacturing facility). It turned out that at about $0.25/liter it was cheaper just to throw it away, rather than pay electricity costs, amortized capital cost, etc., for the closed system! (Most customers realized this and wanted an open system, but ETA dithered over it for two years or so...)
