Has anyone ever used a refrigerant condenser or evaporator coil for the water cooling radiator? If so, how well did it work? I have a few of them laying around and I am about to start a water cooling build, so I was thinking about using this. http://www.qatcom.com/uploads/listing/advert/maram%20refrigeration%20&%20trading%20company%20doha%20qatar%20-%20airconditioning%20condenser%20&%20evaporator.jpg
