This
auction is for TWO FAN SIMULATORS for the Bitmain Antminer Miners or
any other Crypto-Miners with Pulse Wave Modulation (PWM) cooling fans
(4-pin). It works for all Antminers with PWM 4-pin Fans. Its chip
artificially generates a 2200~6500 Fan RPM signal back to the miner's
control board. It can work under 5~36V.
It
is suggested to unplug the front fan and remove it from the miner so
that it will not block the air flow into the miner. Plug the fan
simulator into the front fan socket.
