Design and Functionality

Now let’s take a closer look at Titan Fenrir and Kingwin XT-1264 coolers:


These are coolers of tower topology. Titan solution measured 124x107x156 mm and Kingwin cooler – 120x74x150 mm. They weigh 790 g and 467 g respectively. Each cooler has four heatpipes: 8 mm diameter heatpipes by Titan and 6 mm diameter heatpipes by Kingwin. They are lined up linearly inside the coolers heatsinks:



The heatsink of Titan Fenrir consists of 51 aluminum plates, each 0.5 mm thick. The heatsink plates in the array are spaced out at 2 mm from one another. Kingwin cooler has more plates, there are 60 of them. However, they are thinner (only 0.4 mm) and spaced out at a slightly greater distance from one another: 2.2 mm:



Take a closer look at the top right photo of Kingwin XT-1264: the heatpipes on the left inside the cooler heatsink are about 25 mm shorter than the height of the heatsink, so the top ten heatsink plates simply have no contact with them. The only possible explanation of this fact that I can think of is the manufacturing defect. The sides of the Titan Fenrir heatsink are not covered with anything, while Kingwin XT-1264 has the edges of its heatsink plates bent upwards closing the gaps between the heatsink plates on the sides completely.

The heatsink plates also have different profiles, but it is obvious that both manufacturers tried to lower the airflow resistance. For example, Titan curved the heatsink plates on both sides. While, Kingwin created wave-shaped edges where the airflow from the fan approaches, which also minimized airflow resistance.



The heatpipes coming of the base of Titan Fenrir cooler look quite common, they haven’t been even shifted away from one another. As for Kingwin, even though there are no special optimizations aimed at more even heat distribution over the heatsink, they added an additional heatsink array of 11 small plates at the bottom of the primary heatsink:


As we can see, the engineers did their best to use then entire effective heatpipe surface as effectively as possible. Here you can also clearly see two heatsink plates in the lower part of the Kingwin cooler that are slightly longer than the others and must be designed this way to direct the airflow towards the mainboard electronic components around the processor socket.
