Ack, you guys aren't very water-cooling inclinded.
Not meant to insult.
I am using Watter Wetter right now, and temps are fine, but Watter Wetter has been found to turn into a foam after long use, and after just 3 months of 24/7 running, that tubes are cloudy, and I noticed a white film in one water block. Bad signs.
I realize that pure distilled water is the best coolant, but I need somthing that will prevent 1) corrosion and 2)little green creatures!
Antifreeze kills alge, and if I use a little bit, it doesn't inhibit cooling power to much.
THe correct percentage I found from water-cooling people was about %15.
