Why use water? - Page 2

post #11 of 20
coolant in cars IS 50% water... but the other 50% is a bit too corrosive and toxic to use inside of a PC -- typically a great coolant mix for a pc loop is 5-10% antifreeze (mainly xx-glycol/additives) diluted in 90-95% pure distilled water.

Water has a relatively high heat of vaporization, high surface tension, wide availability, and is harmless to humans (and in its purest form) harmless to electronics as well. This is why we use it.

"watercooling" allows the heat to dissipate faster as the channels or fins in the waterblock transfer the heat to the water, which lead trough tubes and is cooled down by the radiator allowing higher voltage and a higher OC (on a chip with potential to clock higher)

just wondering......, would hydraulic oil work? (cancels out the shortcircuit caused by water)

Specific heat of oil is not as good as water. It cannot store and transport as much heat as water.

Water is very good at absorbing heat with such a high specific heat value. That means it absorb a lot energy. You do not want a liquid that evaporates or expands when heated with a 200-300w. Who cares if the heat is in the water? As long as the heat is not in your processor or components.

I use 95% distilled and 5% zerox super coolant, Quads at 29C so it must be working

But seriously, water obviously works good... or people here wouldn't be using pure distilled water with that other stuff added in, vinegar, iodine or w/e you kids now adays in.

And seems to me a lot of people use coolants and bottled stuff, like that FluidXP or w/e.

The stuff added to cars is used to change the boiling and freezing point of water and actually reduces the waters ability to transfer heat
