ASIC miner repair guide and tutorials

How to check and replace ASIC miner cooling fan and PSU cooling fan？ Miner fan or PSU fan is almost the most vulnerable component because of the continuous work of miners. High-strength and high-speed working methods can easily cause damage to its bearings and internal coils. When the fan is damaged, the miner or PSU will lose heat dissipation and cannot work or damage the chip. Therefore, regular inspection and replacement of bad fans is an essential job of maintaining miners. Both ASIC miners and GPU miners use a large number of cooling fans. Depending on the device model, the fan specifications used are also different. Normally, the most common fan sizes are: 4cm, 6cm, 12cm, 14cm. The standard voltage is 12V, the current is 0.27A to 7.2A, and the power cord is 2 to 6 pins. The specific size of the fan to be selected needs to be determined according to the device. When these fans fail, it isn't easy to detect from the appearance because one piece of equipment is equipped with 2 t

How to choose replacement chip for the Bitcoin Antminer? Since the birth of cryptocurrency, people have begun to use all kinds of equipment to mine, from the simple preference at the beginning to the later profit, and use it as a profession. From desktop computers, laptops, tablets, mobile phones, GPUs to professional ASIC miners, people have been trying more efficient mining methods. Finally, GPU miners and ASIC miners have become the main tools for mining cryptocurrencies with highly high hash rates and energy consumption ratios. Among them, ASIC miners have a share of about 70%. It is a huge market, including manufacturers, sellers, miners, and maintenance personnel. The ASIC miner concentrates a large number of ASIC chips on a circuit board. Its name is "Hash Board." Depending on the model, a hash Board will load dozens of ASIC chips. They are similar to those of a computer. The CPU is responsible for calculating the hash value in the blockchain. A mining machine usually
