Taking a look at 4Ryans stickied thread about his open loop system using the 8 gallons of water, got me thinking about something. I haven't experimented with any water cooling yet, so pardon me if this is nonsensical. He was using several gallons of water cooled with two gallon containers of frozen water submerged into the entire reservoir, changing them out every few hours to keep temperatures regulated. Would using salt in the distilled water that is being circulated help cool the CPU more? Salt lowers the freezing point of water, so I would think this would indeed work. However, would the salt damage the lines? Would the benefits be at all noticeable, or even negligible? Just a thought. What are your opinions forum?
