The GlacialTech Alaska claims to have one of the world’s first heatsink fins with a “breathing effect”. It’s hard to say exactly what they mean by this, since there is no documentation on it. The Alaska does have a unique fin design, which is not only rigged on the outside, but rigged on the top/bottom.
The fins appear to alternative back and forth with their design. Two plateaus extend the length on either side of the fin. The next fin above is essentially the same, but just flipped over so that the plateaus of both fins are almost touching. This fin design extends all the way up the heatsink. Getting a closer look at the top of the heatsink you can see that it has multiple holes in it; this design extends all the way down the heatsink.
The six, 6mm heatpipes with nickel coating extend the length of the heatsink in a U-shaped design in both the way they are sent through the heatsink, and the way that they are aligned on the heatfins.
The copper base also appears to have some coating on it, presumably nickel, but is not nearly as reflective as the heatpipes.
