"So here it is. A well marketed, acceptably manufactured, and very difficult to install cooler, marred only by it's substandard performance... it really seems like everything went downhill since I opened the box. While there are a number of good ideas here, they all falter on the same lines. Let's start with the simplest one. By layering the two sets of fins over each other, a lot of the heat dissipated just goes to return, and heat up the fins below. This isn't the first time, or the first company to have this problem, nor are they to try and alleviate it in a simple manner - put the cooler fins on top."
