One more question:   The minimum fan percentage that my installation of the controller firmware defaulted to was 100%.   The mini-documentation beside the field on the page says the default value is 10% but it burnt into my controller with 100%.

So my fans my on 4 841 miners run full blast constantly, even on these cool nights where chip temps are in the 50/60C range.  Should I change it to the default so I will get variable fan control?  Or did Canaan realize these 841s need 100% fan all the time?

Thanks again!


You can change the minimum, I did. 

Thanks - so I dropped it back to 50% and even with ambient temps in the 68-70 degree range the fans ran back up to to 90+%   I guess unless you have your farm in the north pole you end up with ~ 100% fans anyways.
