Miner fan simulator (2 connections for one miner)

GOPRASOFT Fan Simulator is a 2-fan simulator for ASIC Miner.

If you equip your ASIC Miners with oil cooling, water cooling or an external cooling system, the fans are a hindrance. They are loud, disturbing and still consume power unnecessarily.

Remove your old fan with the plugs from the control board. Then connect our adapter to the front and rear fan connectors on the control board using the supplied plugs. There is nothing else to do, that's it.

In the ASIC Miner overview you will see the fan speed being simulated. The ASIC Miner starts normally and can start operation.

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.
