Hi iv just bought a de-ionised water at local Halfords in UK they guy said its the same as distiled water as i am using fractal design kelvin s36 Cpu Water Cooling System the tech guy at Fractal Design website told me to use from Support> Deionized water still has salts and minerals in it which can harm the cooler, so it is not the same as distilled water, where all the minerals are removed.
You can put in the distilled water as it is as the coolant already in will be enough.
