Get an idea from this thread below only if you have root access

- https://bitcointalk.org/index.php?topic=2616205.msg30730555#msg30730555

or read the whole thread using this link https://bitcointalk.org/index.php?topic=2616205.0;all;wap

Then use the search CTRL+F then type this term "fan speed"

I hope it helps.

As an example for setting minimum speed of 10% and max of 30%, under More Options use
--avalon8-fan 10-30

841 setup to be a quiet space heater:
Power mode: Low power
More Options: --api-listen --avalon8-fan 10-25

That will take power down to around 850-900w with fans maxing at 25%. Runs around 8.8THs

Do be aware that when slowing down the fans you also need to make sure the miner is in a lower power mode or else it will be rather unhappy and just run as fast as it can with the fans throttled down, as it overheats it will begin self protecting by slowing down the hash rate.

Hi mate .First thank u very much.It's working perfectly  ;D. My device is A-851S set fan speed on 50% , hash is 9 T/H , 600-650 W,
Do u know can  control Fan speed of Bitmain S11 ?
