Solution for ANTMINER S9 FANS SPEED Up & Down every 20 Seconds.

[DickyDck]

Is there a file we can modify to permanently make these features visible? I'm looking around in all the config files with WinSCP and can't find it. This would be a much simpler and faster way. Not that F12 Dev consoling is hard, just trying to keep everything in the gui.

Easier method than editing the css.

Go to miner configuration.
Right click inspect, go to the console.
Then paste in

Code:

$("#fan_ctrl").show();

and hit enter.

The fan control will show up, no need to edit any css.

for the other options.

Code:

$("#beep").show();
$("#temp_over").show();

Also, anyone wanting to overclock or underclock farther than the page displays.

Code:

$("#ant_freq").append('<option value="500"> 500.00M </option>');
$("#ant_freq").append('<option value="450"> 450.00M </option>');
$("#ant_freq").append('<option value="400"> 400.00M </option>');
$("#ant_freq").append('<option value="350"> 350.00M </option>');

Code:

$("#ant_freq").append('<option value="700"> 700.00M </option>');
$("#ant_freq").append('<option value="750"> 750.00M </option>');
$("#ant_freq").append('<option value="800"> 800.00M </option>');
$("#ant_freq").append('<option value="850"> 850.00M </option>');

Gave it a try, however after hitting enter nothing showed up, perhaps I am doing something incorrectly?

Chrome or firefox? I have only tried this on chrome, I know firefox's console is pretty locked down.

Thanks for getting back to us! I was trying on Chrome, let me look at these last sets of pics and try again

[DickyDck]

ok, so it worked this time, thanks but it seems that even if I choose a different frequency it doesn't stick. Was worth a try though, thanks again!

[DickyDck]

Hopefully this won't get removed since it is relevant to this thread topic, I'm wandering the various configs via WinSCP, and I'm wondering if we can just enter in the code in the bmminer.conf file somewhere in here to get the FAN PWM, and the Frequency...

"api-listen" : true,
"api-network" : true,
"api-groups" : "A:stats:pools:devs:summary:version",
"api-allow" : "A:0/0,W:*",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "100",
"bitmain-use-vil" : true,
"bitmain-freq" : "550",
"bitmain-voltage" : "0706",
"multi-version" : "1"
}

It likes the PWM 100 setting but even though I save it as 550 it doesn't change the frequency after the bootup. Any ideas?

Doesn't work. Using chrome.

Hi, but how can i access to inspect?
I must be  set FN+F12?
If i Right click on the mouse appear a windows for selection..... i don't understand.....

Autotune firmware ignores the frequency setting. You have to be on a fixed freq firmware in order to alter the frequency like that.

Ok, I'm going to go really old school simple hardware hack. The fans are a 4 wire PWM plug. one wire is (+) power, one is (-) ground, one wire is reading RPMs of the fan, and one controls the RPMs of the fans. I haven't grabbed a voltmeter yet to figure out which is which, but could we just jump the speed signal wire with the hot wire and make the fan run full speed all the time? Just a thought for those of us who are not worried about noise levels. I have found that even when I use this web browser mod, it still only sets one of the fans, and there is a discrepancy between speeds.

If you cross the +V with tachometer you will get the maximum reading of 255. Since the fans read rpm in multiples of 120, 255 * 120 = 30600 RPM.

At least with the latest version of the firmware (Nov 2017), the software understands that the tachometer has shorted, and will stop mining if either fan has the 30600 rpm speed.

Good to know, however what I meant by "signal" wire was the control wire that sends the signal to tell the fan how fast to spin. I've done 2 different methods of software modifications but it seems they only last for a while and somehow they get overwritten. I just want these things on full blast all the time and some sort of good signal to go back to the PCB so it knows they are spinning and aren't broken

I just found another post here on the forums about cutting the blue wire... and it worked :p thanks for the earlier reply with the information though, if you hadn't told me I might have tried the splicing.

Glad I could be of some help

The blue wire tells the fan how fast you want it to spin, and the yellow one tells you how fast it is spinning. I had assumed "the signal" to mean the yellow wire.

Generally if you are using a 3-pin fan or the blue wire has been removed, the fan will spin as fast as possible.

I dont know what i do wrong but if i press FN+F12, the secret menu dont show. Any help?

Easier way

Add these line to /config/bmminer.conf using winscp set connection file protocol SCP

Code:

"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "90",

Then restart bmminer logging SSH using putty

Code:

/etc/init.d/bmminer.sh restart

When finished fans will run at 90% or whatever % bitmain-fan-pwm is set to.
