Re: On the same day you post your article
You have to admire that the article gave two large paragraphs of the short article under that link over to the "custom cooling" system, a description which boils down to "two fans suck air in the back and blow it out the front over the top of the graphics processor gubbins".
In other words, the custom cooling solution is like any other computer's cooling solution, just with the outside-to-inside-the-casing airflow reversed.
