Putting them on the radiator is not really going to do anything but block the airflow which is needed to make the rad work. You are better off with another psu and a generic one should power those little peltiers no worries. Peltiers are gernerally a bit of a pain to get working properly, Im still having hassles after lots of trial and error. At the end of the day you are probably better off not using the 50 wattt pelt for anything Im sorry to say, Ive gone and bought the 25 the 55 the 67 and they all dont really have the grunt to do anything worthy, Im even thinking my 226 watt pelt is not cutting it at the moment and getting something a lot more powerfull. By all means play around with them because you learn and you move on to the bigger and better things like 400watt + pelts and then refridgerated cooling which will cost you a fortune to run in bills and may only result in a OC being not a hell of a lot more than you would be with water on a cold day! Im continuing on my little cooling projects but if you are doing it on a rig you dont want to destroy if you can help it then dont do it and just enjoy what you have got
