Hi Guys I have trouble with my Inno A9 Zmaster fan speed. You can hear it rev up and down then up and down. So I checked the miner logs and it seems that the fan SET speed and Target speed keeps changing. What do you think is going on? Do I have faulty fans or is the miner faulty itself? I contacted Inno themselves but they cant find a solution... I would greatly appreciate if anyone have any sort of a hunch to begin looking at why this is happening. Thank you!!

check all 4 cables from each fan so they all have contact with controllerboard

you could do a factory restore and see if helps ! ! !

have you updated to latest firmware ? ? ?

have you been tinkering with config files or read write permission in filessystem ?

have you cut power and waited a few minutes before connecting PSU to wall plug ?

BE CAREFUL so you don't break anything when unplugging and plugging in fan-connectors:
have you disconnected one of the fans to see if the other one works ???
if not reconnected first and disconnected the other fan ???

you can set fan speed in config file

SSH into machine with putty.exe if using windows

user: root
password: blacksheepwall

cd /config
vim cgminer.conf  (opens file in vim editor, google vim editor and learn commands)

use arrowkeys and move down

press "i"-key for (insert text)

if you set to performance in speed you want it to look like this at end of file:

      }
    ],
    "api-listen": true,
    "api-port": "4028",
    "api-allow": "R:0/0,W:127.0.0.1",
    "A1Fanspd": "30",
    "A1Fanmode": "0",
    "T1adjust": "3",
    "T1performance": true
}

important you don't miss any "," at end of each row and the last row should NOT have any ","

MAKE SURE you don't change anything else but adding this:
    "A1Fanspd": "30",
    "A1Fanmode": "0"

if you only want fanspeed maually at 30%

OR

ad this:
    "A1Fanspd": "30",
    "A1Fanmode": "0",
    "T1adjust": "3",
    "T1performance": true

if you want fanspeed manually at 30% AND "performance+" as speed setting IF you have latest firmware from sept 11 2018.

AFTER it look like this:
    "A1Fanspd": "30",
    "A1Fanmode": "0"
}


OR like this:

    "A1Fanspd": "30",
    "A1Fanmode": "0",
    "T1adjust": "3",
    "T1performance": true
}

depending what you wanted to adjust

NOW press "Esc"-key ONCE

after pressing "Esc"-key only one time you write this:
:wq!
and Press "enter"-key
warning will show up
Press "enter"-key again

now write:
cat cgminer.conf
and Press "enter"-key

you will now se the text of the file and VERIFY that you not messed up!!!

now reboot your A9 and see if it holds 30% fan speed


Please report back findings and solutions for everyone to see :)

It dosent seem to work, I put all the codes in correctly but everytime i reboot the system this is what i receive as errors. NEED HELP! PLS!

Have you changed the file
"/etc/cgminer.conf"   instead of   "/config/cgminer.conf" ? ? ? ? ?



'}' expected near '"A1Fanspd"'


It seems to ask for a }

I wrote this:
AFTER it look like this:
    "A1Fanspd": "30",
    "A1Fanmode": "0"
}


You can clearly se a } at the end of the file and on the row above there is NO , at the end !
Have you done this correctly ???

Have you changed in the correct file ?

What does your file view EXACTLY if you do this for a file you NOT should change:
cat /etc/cgminer.conf

and you do this for the file you where supposed to change incase the problem wasn't anything else:
cat /config/cgminer.conf

I had the same issue, and this DOES work perfectly.  Fan runs at a constant 30% now and is not chasing the target.

You have to add a comma (,) at the end of the ("api-allow": "R:0/0,W:127.0.0.1") line; its not in the original conf file.
