The whole concept of liquid cooling is to achieve greater dissipation of heat than the conventional air-cooled method in order to assist in overclocking experiments or to eradicate noisy fans from the system. Hence, the liquid coolant is the medium and lifeblood. For the 3D Galaxy II, it is dyed in the fashionable blue favored by enthusiasts and actually goes with the blue LEDs on Gigabyte's 3D Aurora line of casings. Only this anti-freeze/anti-corrosive coolant should be used in the coolant tank that has Gigabyte's unique low water and over temperature protection.
