Used Antminer S17  (56Th)

The second-hand Antminer S17-56T's power supply model is APW9, and three Nidec 12V 0.64A fans are used to provide heat dissipation for the power supply. After testing, the temperature of the power supply outlet is slightly higher than that of the hash board, but it is observed that the interior of the power supply is full of materials. Components do not affect the operation of the miner

After the fan is removed, you can see the situation of the internal computing power board. You can take out the three boards built in the Antminer S17-56T by removing the baffle plate. Each computing power board contains 48 Bitmain second-generation 7nm BM1397 chips. A total of 144 chips (consistent with the number of 144 blocks produced by Bitcoin per day, is this a coincidence?) constitute the computing power of the 56T SHA256 Bitcoin mining algorithm

The second-hand Antenna S17-56T is well-designed, and the cooling fan power cable is protected with an isolation layer in the wiring to avoid the risk of damage and short circuit caused by the fan power cable being squeezed.

The physical size of the second-hand Antminer S17-56T is similar to that of the Antminer S15, but the hash board is shorter. After the hash board is placed in the chassis, there is still a certain space in the box. Why not consider the cost factor to make the box smaller? ? The reason should be that the air volume on the air inlet side can pass through the heat sink more evenly
