A quote from the article:
>> Thermalright True Black 120 CPU Cooler Review
The True Black 120 CPU cooler features a solid copper base, six U-shaped heat pipes and a large aluminum fin array. Although there are physically just six heat pipes, the U-shape configuration results in six evaporator sections (where the heat pipes contact the base and absorb heat from the CPU) and twelve condenser sections (where heat is dissipated into the aluminum fins). As we will see later, this results in a very efficient heat transfer arrangement!
