Producing this epic took hours, days, weeks and months of reading, talking to DEX and cooling system experts and users, writing, rewriting and then starting the whole procedure over again. It has consumed more than 8 months of my life. (Yes, a lot more than it should have due to health problems.) Frankly, the difficulty was finding any one person who could factually layout the “whole” picture. I’ve not yet spoken to any single individual who is either able or willing to share it “all.”
