What water should I use for my AIO water cooler?

Solution
If it's losing coolant you need to return or replace it. Water leak + electronics = FAIL. You'll be buying a new system soon if you don't do one of the two. Leaks are not ok. You need to either figure out why it's leaking and fix it, RMA the unit or replace it. That unit should have a two year warranty.

As far as the water is concerned, generally distilled water is fine.

Its not that it's leaking but just over time it's loses the amount of water it has. There's no visual crack or moisture around the area so it's just that fact that it loses water over time. Also can you possibly send me a website to where I can buy red water?
 
Water doesn't just disappear. If it's losing water, it's going somewhere. It might be leaking slowly enough that the heat from the system is evaporating it, but it's still bad. There is no argument to this plain fact. If the water inside the cooler is not staying put, it is leaking out. Water coolers should be capable of remaining at the same level indefinitely, aside from needing to be changed out periodically for treatment if there is contamination or algae growth inside. It should not lose water, period.
 
If this cooler is within warranty, you should RMA it. If you're 'losing' water you either had a lot of air somewhere in the loop that displaced into the reservoir or wherever it is visible, or like others have said, you have a leak...perhaps even a very slow one. I realize this reply is a couple weeks later, but this isn't likely something you'll want to simply try to bandaid over.
 
Can you Fill an AIO? Mine is factory sealed. Over time you will lose Coolant because the Pipes will sweat but I would only be concerned if it effects temperatures. I've never had one lose enough coolant to be a problem but i don't Keep my systems over 3 years.
 


Over time you should not loose coolant. This is considered a leak. The tubing used in watercooling is quite impermeable and water isn't going to magically dissipate out.
