The Cogage Arrow
In Figure 4 you have a front view of the cooler. The four U-shape heatpipes have a diameter of 8 mm.
In Figure 5 you have a side view of the cooler, where it’s clear that the two tower heatsinks are completely independent. Note that the fins are not plain, but have their edges curved up and down in order to get better air contact.
In Figure 6, you can see the top of the cooler. Note the shape of the fins, looking like arrow tails, justifying the name of the cooler.
