Figure 4 reveals the front of the heatsink. The six heatpipes are installed in two rows, since both sides of each heatpipe come into the heatsink.
From the side, the heatsink seems to be very small.
Figure 6 shows the top of the cooler. The fin shape is simple.
Figure 7 presents the structure of the heatpipes at the base.
