I have shared a series of e-mails w/ the Prolimatech folks with regard to how best to position their cooler. It's one that you can install in any direction you want and has the easiest mounting system ever employed according to most test sites.
Based upon their tests, and contrary to my assumption, the best way to install the cooler is to blow air to the rear of the case. Given the laws of Physics, I woulda said blowing straight up and out the 200m case top fan but their test showed slightly better performance blowing to the rear .... I'm guessing that in that set up it get cooling both ways from hot air rising as well the push - pull to the rear.
