(1)The liquid in a CPU water-cooled radiator is usually distilled water.
(2)Distilled water - unadulterated, non-corrosive, non-deteriorating, and suitable for circulation in closed pipes.
There is also the concept of "deionized water", "ultra-pure water", etc. There is no significant difference in the thermal conductivity of this water, the main selling point in the leakage of electrical conductivity, as well as the need to replace the liquid frequently! The main selling point is the conductivity of the liquid after leakage and the frequency of liquid replacement, the more "pure" the water, the lower the frequency of replacement, the lower the conductivity.
