I tried, it does not work on the B3. Both fans still at max speed.

Tried this:

"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50"

and

"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50",

I thought a comma , was missing behind the "50" but no change ...

Same for me, tried:

]
,
"api-listen" : true,
"api-network" : true,
"api-groups" : "A:stats:pools:devs:summary:version",
"api-allow" : "A:0/0,W:*",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50",
"bitmain-use-vil" : true,
"bitmain-freq" : "_ant_voltage=0706",
"bitmain-voltage" : "0706",
"multi-version" : "1"
}

and this:

]
,
"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-freq" : "_ant_voltage=0706",
"bitmain-voltage" : "0706",
"multi-version" : "1",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "50"
}

But no change, fans seems to be still at 100%. Anyone was able to change fan speed?

Sounds like you need to disable fan control?

Maybe something like:

"bitmain-fan-ctrl" : false,

Just tried to put :

"bitmain-fan-ctrl" : false,

Rebooted the miner and nothing changed, still very very noisy.

Went to /var/log/ to look for any clue... but nothing useful.
