Design and Functionality

Doesn’t it look familiar to you?

 

 

True, this is none other but a nickel-plated and polished off Cogage Arrow heatsink, which in its turn is none other but Thermalright IFX-14 with modified heatsink fins. So, you probably wonder how Thermalright is going to regain its leadership? Well, let’s find out.

The Silver Arrow cooler consists of a copper base plate, four copper heatpipes 8 mm in diameter, two heatsink arrays with 0.3 mm thick aluminum plates that are spaced out at 1.6 mm all contact spots are carefully soldered together, so that no soldering residue is anywhere to be found. The ends of the heatpipes are covered with tall caps. These caps make the cooler 166 mm tall instead of the 160 mm as indicated in the spec sheet. It is 147 mm wide and 123 mm deep. The heatsink weighs 825 g.

 

The entire structure is nickel-plated and polished off to mirror-shine. The distance between two heatsink arrays is 39 mm:

 

The calculated effective heatsink surface of the Thermalright Silver Arrow cooler is 11,560 cm2. Each aluminum heatsink plate has eight petals along the edge with one beveled corner that are bent in different directions. According to Thermalright, these petals should help reduce the airflow resistance and push the airflow faster through each of the heatsink arrays. It these particular petals that make Silver Arrow extremely efficient even with low-speed cooling fans.

The heatpipes are arranged very simply inside the heatsink arrays: they are all lined up along the same axis and pierce the heatsink arrays right in the center:

The thinnest part of the copper base is 2 mm and each heatpipe lies inside a special groove:

The 40x40 mm base of this cooler is finished in a typical manner for this Taiwanese company:

As for the flatness of the base surface, it is also the same uniquely uneven contact area, which is also typical of this Taiwanese manufacturer:

 

Despite this fact, the cooler is pressed against the entire CPU heat-spreader, although the pressure is uneven, which is something we have expected to see considering how bend the cooler base is:
