Wouldn't this cool the cpu loop well bellow ambient and also allow for anti algae, dye and less corrosion to the system?
Let me think on this. I bet there are coolers like this out there. In fact. I think it is the basic principle that refrigerators run on.
Yes, some people run dual loops. An open evaporative loop and a closed loop with a fluid to fluid heat exchanger.
About corrosion. There should not be any corrosion assuming you do not have any aluminum in your loop. As far as critters in the water, humidifier biocide works well, and so does silver (see the new silver kill coils at Petra's.)
The real advantage of a dual loop (imho) would be as a fail safe in case you forget to keep water in your evaporative loop (although the silence should be a good indicator that there is no water in it....)
As far as refrigerators go. No, this is not how refrigerators work. That is called phase change cooling, it involves a compressor, and is a lot more complex/difficult to build. There is a section on the forums about that type of cooling.
