phase change and liquid nitrogen are extreme cooling methods...
neither one of which is an air or water cooling method. so i'm not sure what all your coughing is for, try some Robitussin
what I meant by "simple water cooling" is a standard closed circuit system (pump, waterblock, radiator*, reservoir*, and tubing [*=optional]). there are of corse other, more elaborate (in other words... not simple
) methods of water cooling that can yield below-ambient temps such as evaporative (or bong) water cooling, or adding a TEC/peltier or water chiller to the system. while those more complex watercooling methods may allow sub-ambient temps, they all have side effects that must be dealt with and require more maintenance that a simple closed circuit system does.
