  As the original GPU (not called GPU at that time) generated little heat, heat sink is not an essential component for the GPU chips. after a time, Nvidia officially proposed and established the status of GPU, and the iteration of performance even surpassed Moore's Law in some cases. For this, you can refer to the Pascal (Pascal) architecture used by Nvidia released graphics cards in 2016. As the performance improves, the heat generated by the GPU is also getting more and more, so the heatsink of the GPU begins to evolve.

  At the beginning, Nvidia is just a chip manufacturer, so various heat sinks are designed by the graphics card plant to attract the consumers, after a while that AMD and Nvidia took actions and released new graphics cards (architectures) in order to expand their influence. After the tape-out was successful, they designed and produced a graphics card (we define it as the public version) by themselves. heat sink and PCB board combined together at that time. 

  But the problem is that both Nvidia and AMD limit the frequency to control the heat generation of the graphics card for the stability , which is one of the reasons why the graphics cards of other manufacturers are better than the public version in all aspects. Later, the manufacturers changed the heat dissipation form of the graphics card, and the common non-public down-pressure GPU heatsink appeared. Anyone who has hardware knowledge knows that, to a certain extent, the denser the fins, the higher the air volume passing through, the higher the heat dissipation efficiency the heatsink has, but the public version of the graphics card is limited by the heat dissipation method, and the fin area is much less than the non public version heatsink.

  To improve the performance of the GPU, the thermal efficiency of heatsink is the prior consideration. For the GPU heatsink, the most common heat sink type is aluminum zipper fin heat pipe GPU heatsink, this design integrates the benefits of all components:

Aluminum zipper fin: As we know, aluminum is a great thermal conductor and compared with other metal, it has better heat dissipation ability, the function of the fins is to dissipate the heat to the medium as soon as possible, so aluminum is the best material for the zipper fin, besides, aluminum alloy is very cost effective, it can save a lot of cost.

Heat pipe: It is a heat transferring element with extremely high thermal conductivity. It transfers heat through the evaporation and condensation of liquid in a fully enclosed vacuum tube. It uses fluid principles such as capillary action to play a similar refrigeration effect as a refrigerator compressor. It has a series of advantages such as high thermal conductivity, excellent isothermal property, heat flux density variability, heat flux direction reversibility, long-distance heat transfer, constant temperature characteristics (controllable heat pipe), thermal diode and thermal switch performance, etc. The heat sink composed of heat pipes has the advantages of high heat transfer efficiency, compact structure and small fluid resistance loss.

Copper plate: Becasue of copper has much better thermal conductivity than alumiunum, so usually we use a copper plate to contact the GPU to improve the heat conductivity which can transfer the heat from GPU faster than other metals and cool down the GPU.
