Attention Antminer Users! Fan Simulator for Various Models

Hey everyone! This is for all Antminer models: S9, A3, E3, X3, Z9, B3, T9, V9, D3, and L3. Also compatible with other miners like DragonMint, Obelisk, Avalon, Baikal, and Innosilicon. Check out this miner fan simulator, which connects to two fans for one miner. The GOPRASOFT Fan Simulator is designed for ASIC miners with two fan connections. If you're using oil cooling, water cooling, or any external cooling system, those fans can be pretty annoying. They make noise and waste energy. Just take off your old fan from the control board, plug in our adapter to the front and rear fan connectors using the provided plugs, and you’re set. It’s as simple as that. In the ASIC Miner overview, you’ll see the simulated fan speed. The miner will start up normally and operate as expected.

Only thing I would suggest adding is a strobe input via opto-isolator to turn off the fan simulation and force the miner(s) to shut down. The strobe would be fed from a flow switch somewhere in the system. That way if you lose a pump or other problem you don't very rapidly get a tank of very hot fluid. The opto just makes it easier to parallel as many strobe inputs as you want to be fed from the switch.

What's wrong with using a dirt cheap PWM pulse generator?

Nothing if you have one or a 555 timer/couple resistors & caps with knowledge to make one. For those who don't, this is plug-'n-play.
