Sorry for the really soft voice recording in the video, please refer below for the written instructions:
You will need to download Putty and ssh to the IP of your miner. Once there log in using root as the username and the password you've set up, I believe the default is also root. Once you're logged in you are now at a Linux prompt, with access to the file system inside your miner. Use the following steps to set the fan speed manually.
* Navigate to the folder with your config file, type:
* We need to make the bmminer.conf file not read only, type:
chmod 755 bmminer.conf
* Enter the vi file editor, type:
You are now in the vi editor, you should see the entire contents of the bmminer.conf file on your screen, expand the window if you need to. For instructions on using the Vi editor please see the great write-up at the link below. Note you can't change the file until you write it, so don't worry about keystrokes or messing up, just don't write until you're done! http://www.control-escape.com/linux/editing-vim.html
* You need too add the following two lines above the line that reads "bitmain-use-vil":
* "bitmain-fan-ctrl" : true,
* "bitmain-fan-pwm" : "100",
To do this move the cursor down with the arrow keys, navigate to the begining of the line that reads "bitmain-use-vil", click i, this puts you in edit mode, hit enter to add a blank line, click up to position your cursor in the blank line you just created, copy the above two lines, right click to paste them into the config file.
Now write the file and exit vi by typing:
You can view the file to make sure the changes took by typing:
If it looks good exit by typing:
You'll need to restart the miner for the change to take effect, you can do this via the gui/browser. Currently I'm running at 65% fan.
