If someone could help I am not able to change the fan speeds at all.
I have got a 13.5 T Antminer S9 and with the 650M Fixed Freq firmware my fans just keep on doing High and low every minute.
I am trying to fix the fan speeds at 90% but the fans seem to be auto adjusting.
Below is the content of my bmminer.conf
"api-listen" : true,
"api-network" : true,
"api-groups" : "A:stats:pools:devs:summary:version",
"api-allow" : "A:0/0,W:*",
"bitmain-use-vil" : true,
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "90",
"bitmain-freq" : "650",
"bitmain-voltage" : "0706",
"multi-version" : "1"
Thanks.
