Hallo guys, how can i change the fan speed of the A9?
For SSH you have Putty.exe.
https://www.chiark.greenend.org.uk/~sgtatham/putty/SSH in to A9:
user: root
password: blacksheepwall
cd /config
Press "Enter"-button
vim cgminer.conf ('vim' = editor) (You should google keyboard commands for vim-editor)
Press "Enter"-button
i ('i' = insert mode) (NOW u can change in that file) (BE CAREFUL)
(Use arrow keys to navigate)
When you check the file it should be something like this:
{
"pools": [
{
"url": "stratum+tcp://50.225.198.65:3336",
"user": "imine2",
"pass": "n=a9zmaster111"
},
{
"url": "stratum+tcp://eu1-zcash.flypool.org:3333",
"user": "t1d35jvkzKcWybpCqojZmgDZkcFC7iBwe8w.111",
"pass": ""
},
{
"url": "stratum+tcp://45.79.223.173:17023",
"user": "imine2.a9zmaster111",
"pass": "x"
}
],
"api-listen": true,
"api-port": "4028",
"api-allow": "R:0/0,W:127.0.0.1",
"A1Fanspd": "30",
"A1Fanmode": "0",
"T1adjust": "3",
"T1performance": true
}
YOU want to add
A1Fanspd and A1Fanmode like you see above
(when done do this)
Press "Esc"-button (ONLY ONCE)
:wq!
Press "Enter"-button
(You will get warning that read only or something.)
Press "Enter"-button again anyway
(verify that your change has taken effect)
cat cgminer.conf
Press "Enter"-button
And for changes to take effect:
systemctl restart cgminer (restart A9 from within SSH session)
Press "Enter"-button
I've set the fans to 40%, but every few minutes (30 to 60) the fans go to 100% for two seconds. Is there a way to prevent this? Or a way to lower the max fan speed reachable?
