The heatsink laid bare

The Thermalright Silver Arrow is a very attractive yet mammoth like in size. The first thing that struck me was how reflective it was thanks to a perfect nickel plated finish. it boasts quality and class with every detail carefully specified to perfection. If we had an award for most aesthetically pleasing cooler, then the Silver Arrow would no doubt earn it. Ample protection from the packaging means that there are no out of shape fins.

The radiator fin array

Facing the front of the cooler, we can see the first fin array. In total, there are 55 fins to create a very dense heatsink so a fan with high static pressure is advisable. Thankfully, Thermalright saves users the trouble by bundling their own TR TY-140 fans. The fins are nickel plated aluminium plates stacked up in parallel above each other. The most notable feature is the shape of the individual fins. Each is rectangular with 4 arrow shaped protrusion on either side of the heatsink. The special Arrow fins are angled just like on previous Thermalright coolers to create a more turbulent flow for higher heat transfer. This is one advantage the Thermalright has over the planar design of the Noctua NH-D14. Each fin has an approximate surface area of 5145mm2 which over the total of 110 fins provides a very large area for heat dissipation.

The side profile of the dual fin array

Looking at the side, the bent fins become more apparent. Each fin stack is 4.2cm wide compared to the 5cm width of the Noctua's radiators. The main benefit of using the narrower heatsink is to create a larger 3.8cm gap in the centre to accommodate thicker fans such as Deltas or San Ace. Down the sides of each radiator are two narrow grooves where the fins have been closed off, most likely to help direct the airflow through the cooler rather than to the side.

Four 8mm heat pipes

The Silver Arrow differentiates itself from the Venomous X and Noctua cooler with its four 8mm thick heat pipes. The sintered heat pipes help to transfer heat from the base more effectively than narrower heat pipes and the construction ensures longevity against the elements. The heat pipes are in direct with the copper base and spread out with each end going through a separate heatsink to cover a greater surface area.

The top of the heat pipes

At the top, we can see how the heat pipes are configured. Each radiator holds 4 heat pipes that are spread linearly so each can dissipate over a bigger area across the fin. Thermalright have done a tremendous job finishing off the cooler with meticulously sculptured heat pipe ends, a nice touch that many high end coolers lack. From the top, we can also see two tiny holes on each side of the radiators where the fan clips install.

The base of the heatsink

The copper base is fairly flat and smooth but lacks a perfect mirror finish like the Venomous X had. In true Thermalright fashion, the base is slightly convex to match the shape of CPU integrated heat spreaders. After installing the cooler, I noticed that it did an excellent job of spreading the thermal paste evenly by simply applying pressure on top of a rice size amount of compound.
