I really need help to change the fan speed. Sitting in my living room and in a few hours imma hear it in my bedroom lol. Here is my json file and I change the cutofffanspeedin & cutofffanspeedout to 75 but same fan noise at 3600rpm (according to dashboard). I'm running version 20180914 or September 14. Can someone share the September 26 version? I believe it has to do with the lyra2rev2-cutoffenable command line but when I download the json file, that line is not available for me to edit. Please help this fan is giving me a headache almost makin me cry

Try disconnecting one of the fans, I did this to the B3 before bitmain implemented the FW fix

The outtake fan is so high pitched compared to the front. It refuses to mine without both fans plugged in. I'm guessing its an rpm requirement. I'm tempted to take the outake fan off the grill, break off the blades, then place my own noctua as a replacement. Someone did that with a previous bitmain to reduce noise. Still looking for that software solution though.
