Thanks for the help, both links (and the links on the links) answered a lot of questions I had, not only about radiators, but fans and airflow. But the bulk of my question still remains. 140.1...I haven’t seen how much a 140mm x 1 fan rad can dissipate. Not even from the manufacturer, even then I would not fully believe the numbers of the person trying to sell me the product. That would be like asking a used car salesman if that beater gets good gas mileage. I guess short of buying one and running my own tests is the only way I can answer my question.
Umm…just as an afterthought I probably could just look up reviews for a corsair h50 or similar “closed cooling loop” for a CPU…they use a 140.1 and probably have similar dissipation. Thanks for the help guys.
