How do you get down to 6TH @ 530w? Do you just unplug 2 of the boards?
Used the autotuning and specified 500w. It says its drawing 491w on all three boards (527w at the wall).

Found a delta afb1212she in a drawer of random bits so going to give that a try which are similar to the ones you suggested philip, so going to give that a try.
I wont bother with the noctuas. I was grasping at straws thinking they might work but any sort of reduction in initial startup noise would be good.
Also I found that power limiting/auto tune setting and it gave me 6Th at 530w (at the wall) so not too bad really. May well follow your setup philip and switch down to a single middle hashboard with some added ducting either side.
Edit,
Found a similar 120x38mm fan rated at 1.7a (afb1212she rated at 1.6a) Both fitted and the initial startup is quieter it produces a whistle now but only until the firmware kicks in. Currently set to 500w power limt and still getting 6Th. Fan speed is AUTO is 1000-1200rpm (32%) keeping things at 80c.
Is there any way to remove the extra fan slots from the graph? Fan ID "0" & "1" are what im using but 2&3 read 0 rpm and obviously dont even have headers on the control board.

I had luck but it can be inconsistent.
The noctua are "fuck you" don't bother with them.
A lot depends on if your chip heat sensors are good.
If they work you can set fans to about 50-75%
I liked the 120x120x25mm delta fans.

1) how does it react to swapping fans, probably to some industrial noctuas 2000rpm?
This is an interesting question, has anyone had any luck swapping the fans using BRAIINS? I know that my S9 after BRAIINS install has a stock fan that bounces all over the place approximately every 30 seconds to a minute.

1) It even lets you run the rig without any fan so I reckon you won't have much trouble swapping fans.
2) Auto tune finds the sweet spot for your power target but it takes quite a long time.

Ok so ive managed to acquire an S9 with PSU and got braiins on it. Now heres my questions (and apologies if they have been asked before).
1) how does it react to swapping fans, probably to some industrial noctuas 2000rpm?
2) Is it just trial and error to find the most efficient setting or does the power limiting autotune do that for you?
Thanks in advance.

yes i hate miners that dont show best share... my innos are like that - no damn best share like wtf....
Monitoring applications like AwesomeMiner have that feature, perhaps if someone is interested in proving that Braiins does find blocks, they could use one of the available monitoring applications, it gets even better when you set email notifications for when your gear finds a block.
it exists if you poll it via API command, but i doubt the source did at the time.
If that particular mining gear is still online since it found a block, we can guide the user on how to pull the best share, of course, that's a big if.

Thanks for your feedback.
Unfortunately Braiins OS doesn't show "Best Share" in the Summary table of the web UI, it exists if you poll it via API command, but i doubt the source did at the time. So now I'm requesting this field to be added to the Summary table (the one you see in that screen capture), and hopefully someone in the future will share it when they find another block.

Looks promising, but more detail would be good, I can't see how to connect those two images. There is no data in either image that relates to the other image. Can you get a screenshot with more info? At least we need the bestshare from the miner gui.

The S17 support isn't ready, but i think the Pro has a good chance, as long as you haven't updated the firmware.
Key point: Don't upgrade.

I have a s17pro with some really old firmware like April 2019.
Could I do it via team viewer?

Don't look at the kernel date, look at the File System Version date.
Ok, so can we install this to a newer S17Pro from January 2020? Don't know the exact file system version.

I asked and was given a capture confirming a block found. I did ask for more details if possible, but in the meantime here you go:

After 59 days uptime. 😊

👍 thank you! That block (height 630368) is worth 7.79874674 BTC.

What appears to be certain, is that the S19 ships with this "feature", and the newer firmware updates in the rest of the S17 family do this as well. So if you even have even the slightest plan to ever try Braiins OS in your S17, make sure you do not ever update the firmware. Because, it is yet to be seen if these could be bypassed somehow (without getting a solder gun, that is).
How old firmware are we talking about?
I have Linux 4.6.0-xilinx-gff8137b-dirty #25 SMP PREEMPT Fri Nov 23 15:30:52 CST 2018. Should be good.
Thinking about buying another one for cheap bucks.

That sounds likely. This has only been tested with the typical Xilinx S9 controllers. And no, you are not supposed to change any permissions to upgrade...
Whatever controller is used in the S9K and SE and Hybrid none of those work.

Did you have to change permissions anywhere when doing the upgrade via the web interface? I keep getting these errors.
Code:
ubiattach: error!: cannot attach mtd2 error 17 (File exists) mount: mounting ubi1:rootfs on /mnt/config/ failed: No such device mkdir: can't create directory '/mnt/config/home/usr_config': No such file or directory cp: can't create '/mnt/config/home/usr_config/mac': No such file or directory umount: can't umount /mnt/config: Invalid argument /www/pages/cgi-bin/upgrade_clear.cgi: line 67: ubidetach: not found runme.sh: line 38: base64: not found cat: can't open '/usr/bin/ctrl_bd': No such file or directory
I am wondering if I am having all these challenges because I have this board: https://www.ebay.com/itm/10pcs-Antminer-control-board-S9K-S9SE-Z11-Z9-Z9mini-V9-10pcs-/173994257105

This remember me about the XBOX 360 DVD units, the last model (XBOX E) got a DVD unit with the firmware locked on the chip, in the end, no one found a way to unlock those chips.
If Bitmain begin to do this i think most ppl are going to buy other brands, is really nice get you old/new hardware and install a firmware like Braiins that let you underclock/overclock and undervolt/overvolt and get more juice from it.

What i read elsewhere is that Xilinx provides this sort of security feature, where you can "fuse" parts inside the chip after you flash the firmware to it. This is probably what the rumored Russian malware that damaged nands did, but I'm unsure if the S9s have this.
