— the classic version of the design: heat pipes pass through a metal (usually aluminium, less often copper) base, which is directly adjacent to the surface of the cooled chip. The advantage of such contact is the most even distribution of heat between the tubes, regardless of the physical size of the chip itself (the main thing is that it should not be larger than the sole). At the same time, the extra piece between the processor and the tubes inevitably increases thermal resistance and slightly reduces the overall cooling efficiency. In many systems, especially high-end ones, this drawback is compensated by various design solutions (primarily by the tightest connection of tubes with the sole), but this, in turn, affects the cost.
