Antminer S19K Pro S19a Z15 pro ASIC Miner 4P fan speed simulator

Antminer S19K Pro S19a Z15 pro fan speed simulator is used to replace the original high-speed violent fan when miners modify water cooling. It is used to replace the Antminer 2*2 pin high-speed chassis fan. By installing a 2*2 pin fan speed spoofer for the water-cooled miner, the noise during the operation of the miner can be greatly reduced and provide a quiet operating environment for the miner. This fan speed regulator is used to connect the fan interface of all Antminer 2*2 control boards.
