HOW TO SET / REDUCE FAN SPEED OF THE ANTMINER S9 - NOISE REDUCTION

34 ratings | 6978 views
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: cd /config * We need to make the bmminer.conf file not read only, type: chmod 755 bmminer.conf * Enter the vi file editor, type: vi bmminer.conf 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: :wq You can view the file to make sure the changes took by typing: vi bmminer.conf If it looks good exit by typing: :q 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.

Easier solution? Go to antminer interface , upgrade , save backup . Backup is a zip file that contain the file you need to edit . Edit it and uploadit to miner using upgrade menu.

I have a problem.. Only allows me to write the name of the user "root " but to ask me the key is frozen and does not allow me to write anything more... I'm trying this with my antminer S9 after program says " server unexpectedly closed network connection" help

when you turn it on, fan goes 100% for a few minutes with some antminers, will this method lower that? or will I always have to deal with 100% fan when turning it on ?

Yuri Hasan as far as i know the method in the video only works for s9, doesn’t work for any others, but you may try anyway

Hey love the video. Very sweet and to the point. I was just wondering if this would work for my antminer A3 or not. And if so would you think it would be possible to change the speed of only one fan instead of both(intake fan)?

This should work for your A3, except edit cgminer.conf instead of bmminer.conf. Not sure about just doing 1 fan. Good luck!
Thomas Rausch (6 months ago)
unfourtentaly it doesn't run for Antminer B3. Do you have an idea? After the reboot it is like I wrote to the config file. But after getting the network it goes to 100%
John Foo (6 months ago)
Thomas Rausch the method only works for antminer s9

Doesn't seem to work, all our system info seems to be the same, but fan still works on auto after new command lines/reboot. Any ideas?
John Foo (7 months ago)
Aaron Cross Change permissions back to original state on bmminer.conf Code: chmod 400 bmminer.conf
Aaron Cross (7 months ago)
3rd times a charm.. not sure what was wrong the first couple times.. - working now. What permissions should reset the bmminer.conf file back to after adding commands? Thank you
John Foo (7 months ago)
you may refer to my description for the exact steps... you will need to change the config file permissions before you can edit and save chmod 755 bmminer.conf i would think that perhaps you should look back into the file (vi bmminer.conf) and see if the 2 lines were actually added and saved. if the lines were added correctly just like the video i made, then reboot. after reboot, the fan still still auto adjusts itself for say around the first 10mins... then fan speed will reduce after that .. a good fan speed to set at 60-65% would ensure bearable fan noise. i experiences that when fan speed is at 80%, there is a whining noise . hope that helps, i am not sure how to guide you further, unless u can post a screenshot of your setting
Aaron Cross (7 months ago)
also should i be changing the config file permissions? what were they originally before 755? Thanks
