As we all know, the Antminer S17 and T17 series are easy to show up the issue about the heat sink, due to the design and materials reasons, the heat sink can easily to fall off the hash board which will cause the chip overheat and burn the hash board. So we now have improve the design and change the materials, In the past, we use the extrusion process for the heat sink, now we cut the aluminum alloy material, which has stronger structural strength and better heat dissipation.
