The Antminer L7 upgrade water cooling kit suits the Antminer L7 water cooling plate. The installation of the L7 water cooling plate can effectively transfer the heat emitted by the hash plate, thereby reducing the temperature of the hash board. As the temperature decreases, the power consumption of the hash board will naturally decrease, which can effectively save power. In addition, the installation of water cooling can also effectively reduce the noise during the operation of miners and prolong the life of the hash board chip.
