Cooler design question.

synolimit

Anyone know fluid dynamics or what have you and design etc for these? Any tests?

Here's 2 coolers. Ones your typical fin design and then one has large half circle holes that you can only see from turning the cooler to the left or the right. The typical fin design if you blow on it, air goes right through. If its 1.5" thick, air will flow through touching 1.5's. the large hole one, since they're cut sideways, you feel no air blowing straight on and holding your hand straight behind. But you can feel air holding your hand off to the left and to the right. This one being 1.5" thick and the holes side ways means air is flowing through 2" of metal and not 1.5". the large hole one, at the front of each hole its cut in half. The bottom of the circle will go to the left and the top of the circle will go to the right.

Any thoughts?
