Arctic Cooling Copper Silent 2 TC revision 2

Arctic Cooling Copper Silent 2 TC revision 2 ... to heat sinks which use a copper core (copper poured inside aluminum), for the Copper Silent 2 Arctic Cooling uses more material over the DIE where high energy flows (copper plate) and in the external areas where low energy flows, less material (only 5mm aluminum plate). Thus a better efficiency is achieved, hence better cooling performance without increasing the weight.

The heat transfer of conventional copper cores onto aluminums is ensured by thermal compound, which transfers the warmth extremely poorly compared to metals. In contrast to this Arctic Cooling uses a super-thin tin film. This has the advantage of approx. 25-times higher heat conductivity of tin compared with the thermal compound.

Compared to the Copper Silent the cooling performance was improved, without increasing the height of the heatsink or violating the height restriction area defined by AMD. Thus compatibility is guaranteed for all Socket A mainboards. Thanks to the reversed fan mounting, the relevant airflow height of 56mm is kept low. The Second Revision of the Copper Silent 2 allowed for the ventilation system to be reworked. The patented "reversed- hanging" fan is able to practically eliminate the typical buzzing sound of 80mm fans.

The Copper Silent 2 TC uses a thermally regulated fan system. For regulation the temperature of the heatsink is measured, which corresponds over a correction curve directly with the CPU core temperature. In contrast to the control over the air temperature the method used by arctic cooling is more complex, but substantially more precise, which lowers average noise levels and utilizes the temperature bandwidth of the CPU more effectively.

The Fan has been mounted onto 4 Rubber supports to stop vibrations being transmitted to the heat sink. Owing to the screwdriver guidance and the joint both the installation was simplified significantly as well as the de-installation and is now even possible under extremely close space conditions in the PC Case. Naturally the Copper Silent 2 utilizes all 6 hooks of the socket, which leads as with its predecessor models to a low socket strain.
