Hi guys i need help.
I use simpleminnig with claymore 10.2

But i cant change my fan control with
This command
fanmin   set minimal fan speed, in percents, for example, "-fanmin 50" will set minimal fans speed to 50%. You can also specify values for every card, for example "-fanmin 50,60,70".
   This option works only if miner manages cooling, i.e. when "-tt" option is used to specify target temperature. Default value is "0".
   Note: for NVIDIA cards this option is not supported.

When i set -fanmin 40,60

Istn work

I can change min fan control only in overclocking menu.
When i set command -tt 75 -fanmin 40,60

I have this message : Failed to set new fan speed check if minner has root acces.

How unlock root acces?
