Antminer S19 water-cooled heat-conducting silicone grease printing mold is used to install the Antminer S19 water-cooled plate, helping the S19 water-cooled plate to evenly apply heat-conducting silicone grease to improve the success rate of installation. The heat dissipation efficiency of water cooling is higher than that of air cooling, which can significantly reduce the temperature of the hash board. As the temperature of the hash board decreases, the power consumption of the miners will naturally decrease, which can effectively save power. After the miner changes from air cooling to water cooling, high-speed fans are no longer needed, and 97% of the heat is taken away by water cooling. Installing a water-cooled row and a low-speed fan for heat dissipation greatly reduces the noise, the temperature of the hash board is greatly reduced, and the life of the chip can also be extended so that the overall stability of the miner is higher.
