3R System iCEAGE Prima Boss II

In Figure 4 we see the cooler from the front. On the base there is a small aluminum auxiliary heatsink. The heatpipes use an amazing design where they are spread in front of the fan, receiving direct airflow.

In Figure 5 we have a side view of Prima Boss II. The sides of the fins are folded, making a closed wall, so the fins create a kind of air tunnel.

In Figure 6, you can see Prima Boss II heatsink from above. Note the fin design, the position of the heatpipes and the surface of the top fin, which is not smooth: has small reentrancies. This roughness makes a turbulent airflow near the fins, which helps the heat transfer.

In Figure 7 we can see the base of the cooler, made practically only by the heatpipes. It is very smooth but has no mirrored looks. We can also see the "iCECREAM V2" thermal compound tube.
