The liquid nitrogen cooling means that the board shoots out a steady mist, emerging from the sides of the board.
The Pentagon said the most likely cause was an obstruction in the krypton precooling system of the infrared sensors that guide the missile interceptor, not the failure of a related nitrogen cooling system.

They laid a thin layer of solid nitrogen, cooled to 85 kelvins, onto a small quartz crystal coated with lead.
They used liquid nitrogen cooling and a pretty serious-looking compressor to suck the heat right out of the thing, and ended up more than doubling the cycles.
