Because this is a straight water cooled rig, the antifreeze is only there to help with corrosion, its not really gonna help bring the temps down.

Distilled water is always the better choice for heat tranfer in this setup. I would recommend no more than a 10:1 ratio of distilled water to antifreeze.
