I have created a cooling system for my S9 miner, and its keeping things cool.  However I need to bypass the S9 fan detection so it doesn't think there is a problem.  I tried plugging in a normal fan, but since they run at 1200 rpm the S9 shuts down. 

I found some references to using a 555 timer circuit to simulate the fan, but was thinking I could buy this...

and use it as a frequency generator to set the speed at whatever speed I needed.  I have not been able to get it to work how I want. 

Does anyone have a workaround, or a suggestion of how to hook this thing up to make it work?
