------------------------------Once you start watercooling, you are almost automatically inducted into the modding circles as well, because theres rarely a 'from the box, fits everyone' solution, its your ingenuity and resourcefulness that makes it all happen, Reply to motopsychojdn
distilled water from your local grocery store is all you need, plus a killcoil or anti bacterial additive.
Car inhibitors are atoms of metals that act as a sacrificial agent to prevent corrosion. If you purchased loop components properly, it should all be copper or maybe nickel plated, which generally work fine together. Just don't mix up with aluminum.
Well that's probably true, but it doesn't make it a good additive to a CPU water cooling loop. You want high thermal conductivity, and it doesn't get much higher than pure water.
