    The trouble is, some biocides/additives use copper sulphate , which also has issues with EK's blocks apparently. Anti corrosion additives are the only way to be safe - they coat the blocks in a thin protective layer which does protect against corrosion. Only trouble is they also coat the inside of your tubing I find but you only need to worry if you have a nickel plated block from EK. No reports of any other manufacturers blocks having issues yet.

    Would anyone here run their car without rust inhibitor in their radiator? The question of whether to use an inhibitor in your PC cooling loop or not is a no-brainer. The fact that it has been little recommended in the past has nothing to do with the chemical properties of water and metals, just a lack of informed opinion. The water, copper and nickel we used 10 years ago is the same water, copper and nickel we use now. their physical properties do not change unless you are able to alter the physics of the universe. If you never considered a rust inhibitor in you cooling loop until now you are a fool. If you haven't ever used an inhibitor and your blocks rust, it is your own fault. All metals will degrade over time when in contact with water, some faster or slower than others. Blaming a product for your own lack of knowledge is passing the buck.

    @bigelf
    Read: ALL metals rust (oxidise), not just iron. The rate of oxidation will be different for each metal. A corrosion inhibitor is essential wherever you place a metal or multiple metal types in contact with water .

    Of course they do but in the case of copper/brass/chrome/nickel (done properly) in a water cooling loop not enough to matter over a number of years.

    Something occured to me today: Shouldnt this only be a problem if you have Alu blocks in the loop aswell?
    I mean if you only have copper and nickleplated copper in the loop it shouldnt really matter if the nickle corroded off to reveal the pure copper. Or is it the nickle that is corroded away that is the problem? not the state of the block afterwards?

    Yes, actually, since then, I have. I changed my mind when I decided to stop following other people's advice about watercooling after building my first watercooled PC and listen to my own advice. I recommend: Distilled water, silver coil AND corrosion inhibitor of some sort.
