Corporate approaches to cooling big iron have stayed constant for
the last 20 or so years:

	CRAY = FREON (tm) [CRAY-1, X/MP, CRAY-2, Y/MP ... ]
	CDC (originally S. Cray designs) = FREON [6600, 7600, Cyber 203,
		Cyber 205, ... ]
	Amdahl = air [470V/6, 470V/8, 580, 5890, ... ]
	IBM = water [360/91, 360/195, 370/165, 370/168, 308x, 3090 ... ]
