Hello! First of all, i hope this is the right subforum for this post. Sorry if i got it wrong.
I am trying to set my miners to have a static fan speed of, say, 60% of the default maximum. After some googling and reading, i found a
reddit thread that said to add some lines above
"bitmain-use-vil" : true, in the config file:
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "60",
"bitmain-fan0-ctrl" : true,
"bitmain-fan0-pwm" : "60",
"bitmain-fan1-ctrl" : true,
"bitmain-fan1-pwm" : "60",
"bitmain-fan2-ctrl" : true,
"bitmain-fan2-pwm" : "60",
"bitmain-fan3-ctrl" : true,
"bitmain-fan3-pwm" : "60",
"bitmain-fan4-ctrl" : true,
"bitmain-fan4-pwm" : "60",
"bitmain-fan5-ctrl" : true,
"bitmain-fan5-pwm" : "60",
"bitmain-fan6-ctrl" : true,
"bitmain-fan6-pwm" : "60",
"bitmain-fan7-ctrl" : true,
"bitmain-fan7-pwm" : "60",
"bitmain-fan8-ctrl" : true,
"bitmain-fan8-pwm" : "60",
"bitmain-use-vil" : true,
This seems to work for setting the fan speed, however when i am deploying the modified config file to all my miners, some of the miners end up not hashing at all. When modifying the original config file, i decided to remove three lines from the bottom:
"bitmain-freq" : "550",
"bitmain-close-low-vol-freq" : true,
"bitmain-voltage" : "0706"
I did this because i was worried that different miners might require different voltage/frequence values (due to potential manufacturing variance). I am not certain whether that was necessary to make it safe, or if that is what's causing some of the miners to get a zero hashrate....but better safe than sorry, right!
Is there someone who's more knowledgeable about these config files who could help point me in the right direction to figuring this out? Full modified config is below, and the full default/unmodified config is at the very bottom.
