Figure 4 illustrates the front of the heatsink. The six heatpipes are distributed at the sides of the heatsink, which is the area that receives the most airflow.
Figure 5 reveals the side of the cooler. Here you can see the two independent heatsinks.
In Figure 6, you can see the top of the cooler. The fins are almost rectangular, and the tips of the heatpipes are exposed.
