Hi guys im having a MARE of a time with one of my desktops, ive got a XPS720H2c and i cant figure out how i check the amount of liquid inside the liquid cooling? ive been told i need "Deionized water" for the liquid cooling is this correct? if so where is best place to buy it from as i see the prices are over a tenner for a 1ltr bottle?
Wilkinson's sell deionised water for 68p a litre. Halfords is about £3.99 for 5 litres. If the unit includes mixed metals i.e. copper and aluminium then you also need an anti-corrosion fluid and 10% anti freeze (Prestone) for car cooling systems works. Adding a tiny amount of copper sulphate available from Wilkinsons as 'King British Green Algae Control' also reduces the risk of algae growth.
However is the unit actually user refillable? If not then it's probably cheaper to put a decent air cooled heatsink on instead.
