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...

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