Coolink Corator DS
In Figure 4, you can see the cooler from the front side. Through the fins you can get a glimpse of the green fan, as well as the four well-distributed heatpipes.
In Figure 5 you have a side look of the cooler, where you can check the two-heatsink design. Note how they are not identical: the rear heatsink (where the fan is attached to) has more fins than the front one.
In Figure 6 you can check the rear heatsink. The manual especifically says to install the fan pushing the air on this heatsink.
In Figure 7 you can notice that even with different heatsinks the shape of the fins is the same.
