Topic: My S9 Heater version (Read 1650 times)
As philip has already said you wont get silence. Mine runs about 45-50db but the ambient room temp is around 18c and as its a space heater it gets turned off at around 20-21c so it never gets that loud, well not for me. There is no point trying to use consumer grade fans, they just havent got the power. The AFB1212 is the best compromise but will never be truly silent.
you can not get silence
but the delta afb1212she is good. with 2 boards at about freq 360
here is a 2 board with 1 delta fan I need to push a little more volts . I set at 8.0 but have some errors
fans at 54% 1800 rpm which are good but not silent.
if you set to 45% fans will go to 1440 rpm but you need to clock a little lower.
like freq 330 and volts 8.0

Change the fan to Delta AFB1212SHE (I think). Single fan will be fine. You will need to change the firmware. Braiins OS works fine. You will need Braiins OS+ to be able to set a power usage figure. I have mine set to 775w now and it gets 10Th. Change the psu to whatever psu you like aslong as it has the right amount of PCIE cables. Personally the HP common slot supplies with appropriate breakout board abs cables works well.
I have got to ask, is Delta AFB1212SHE the fan fan for silencing an S9?
Just tried two Artic P12, it was a complete fail.
The default Nidec Ultraflo fans are utter Sh*t for this purpose, at 25% they are way noisy.
I have one S9 with an unbranded SHLF1212AHE-01, that i set to 45%, temperature performance is the same as Nidec and its much, much quieter.
Whats experiences you guys have with silent fans for S9?
Good 
PS : if you have already download my mod, please re download, i added litle gift i thinks you love it 
So , if you are on the brain firmware, you need make step 1 and 2 on my previous post

Hi, I see that the subject is still interesting.
Philipma, you who are testing, why don't you test my mod for S9? I see that you have installed an old firmware, try mine: D you do not risk anything, you know me, and just see what is in the archive of my mod, only text files! its sorry for you to see you on an old firmware lol
Reminder:
1: Install original bitmain compatible firmware : https://file12.bitmain.com/shop-product/firmware/Antminer%20S9j/Firmware/00720181127220220494P2pANqkd06B7/Antminer-S9j-xilinx-201811301411-autofreq-user-Update2UBI-NF.tar.gz
2: install my mod : https://easyupload.io/ezpjt8
3: Enjoy!
as you already have the firmware that my mod needs, you can directly flash the mod!
it is not worth a big firmware with autotune, but at least it's free,: P

Yeah I have one running in my spare bedroom.
This one is July 2019 Bitmain firmware set to lowest setting
using an evga bronze psu.
I used inspect option to set fans to 1900 speed
Spimply was too lazy to burn a braiins sd card and make it that way.
I did sell more then 1 unit with 2 boards and 1 fan running braiins. as braiins lets you run with 1 fan
I also sold more then 1 unit with 1 board and 1 fan running braiins.
Braiins is better for these space heaters than stock July 2019 bitmain firmware.

WOW!!!
What a great thread, i literally came on here as i have an S9 case/board/controller/fans/Bitmain psu and was looking to build a something of low power and less loud as just having it standard with one card in middle slot with above parts.
I want to reduce noise/power mainly.
So fans would need replacing i presume are they are WAY overpowered to cool just one board?
Plus the APW3++ PSU makes a racket and @ 1600w is not needed for around 4-5Th/one board miner.
Has anyone ever considered this? Replacing fans and psu to achieve this goal?
Thanks

Have you contacted them recently to see if they have dropped their MOQ and/or price? I believe with the resent diff jump as well as price drop they might have become a bit more flexible with these hash boards, I would love up upgrade 30-30 of my S9s if the price is right, I certinally wouldn't take 600 of them.
I could check emails and see if he would sell less.
^ Guys, I think you mean Power Line Communication,
not PoE ?
PoE is for powering devices with 48VDC power supply via an ethernet cable (Data+Power).

That would make more sense actually. I didn’t even think of that option when I was looking into how to make the heater more moveable.

I looked into POE but with limited sockets in my house it wasn't worth the extra expense to set up a whole system. The lan bridge was only £12 and works great all over the house so in my eyes it was a great buy.
Also an RJ45 wifi bridge with wide range voltage input so can work over wifi and be powered from the psu directly...
Nice work you got, regarding the Wireless to LAN bridge, have you looked for something that has POE?
they are pretty darn nice upgrade and will run an s9 shell an s9 controller at 16,5th and around 860 watts
but I had one of the few in the USA. the builder wanted me to buy 600 boards as a minimum which is out of my league

no. I have the exotic special s9 boards 3 of them they are very picky to mine various pools.
you need not be concerned about the three boards as they are not using braiins

they say they do. not sure if that is the only way it mines which is why they won't mine on solo.ckpool and mmpool.org.
I'm sorry for my ignorance, but are you saying that the BRAIINS OS is no good on CKPOOL and MMPOOL, or that they just do not take the boost into consideration?

It is a nice little rig. But the custom boards are fuck you to solo.ckpool and to mmpool.
I'm curious - do those boards have ASICBoost? If they do are they able to use AB on other pools?
I was wondering if a spacer between the fan and the chassis might help things a little even in the orientation I have it.
I would love to have the boards you have but I remember you saying the MOQ was 600 boards which was a bit of a joke really.

yeah I have the one piece set low works nice.
If you have a dead 120x120x25 fan just cut the center out leaving the 120x120x25 frame as a spacer. works a charm for me.

Good to know.
I often wonder if push from back to front is better or pull from front like you have.
I have a 1 fan rig with custom s9 different chips more efficient .
it does 16th and 880 watts.
I push back to front with no front fan.
To make this work correctly I took a dead 120mx120mmx25mm fan cut out the blades and used it as a spacer.
The push then worked really well.

which are the pools I would want to use it to.

Is the fan a push or a pull?
Its pulling from front to back.
Is the fan a push or a pull?
Seeing as this is the space heater thread, I thought I would post mine:-
S9 13.5Th, single fan, dust filter on the front, custom cables, side mounted psu thanks to a side panel from another S9 chassis. Also an RJ45 wifi bridge with wide range voltage input so can work over wifi and be powered from the psu directly.
Running Braiins OS and getting 9.6Th at 760w at the wall. If my math is correct its 79w/Th which isnt too bad.

With Braiins OS+ you just use powerlimit 600* to achieve the same. There are people using all 3 boards with a single fan, with powerlimit set to 900 claiming to be very quiet, so there is a lot of room to improve if you switch to the autotuning algorithm which Braiins OS+ provides rather than use manual settings.
* While it says 600 (watts), this value always assumes 3 boards so its always treated n/3 even if you have two or one board. A feature has been requested to treat them individually. In the meantime 600 / 3 = 200 which is what you want. You could also go lower but won't go realistically do lower than about 100w per board. I tried a single board and it kinda tries to use even lower speeds for about 90w or so, but it works fine producing about 1TH/s or such. And yes, i pointed that to solo.ckpool.org to verify stats.
Remember any evaluation regarding autotuning has to wait until the board reports "Stable", let it work until the end before measuring.
At what wattage was this able to run at? I have to admit I am always intrigued in turning older miners into quiet low wattage lottery devices for the solo pool!
It's doable, but I wouldn't say applicable for all old miners, the miner firmware needs to be customizable because almost all stock firmware on all different mining gears restrict the frequency and voltage you can use, at best they will give you a few options to select from like "Low-Power-Mode" or a set of fixed frequencies to chose from.
With that being said, the S9 is an exception (T9 as well since they use the same control board) using a custom firmware wether it's Braiin's or Vnish (the former is open-source and free) gives you the ability to downclock the S9s to a very low specs and that will make it run somehow quite and power efficient, however not to the extent where you can place it next to your bed, but with a few physical modifications you can reduce the noise significantly, you should check this topic.

If you program the s9 1 board with brains.
You can set hash down to freq 225 and volts to 7.95 or 8.00 or 8.05
this will keep you near 180-225 watts with a low fan speed.
I could be wrong and it will set to freq to 200 but volts go to 7.95 at best.
I was able to do two board at about 380 watts with a quality psu.
I also have the three boards from another builder that fit in s9s
they do a little better on efficiency but dont set lower then freq 300
so they do about 190-210 watts and higher hash.
all of them are hard to go under 180 watts and fans under 2000 rpm are hard to set.
also some act really weird.
I look at your Idea I looked at my idea.
I came up with a different idea.
I will show it next week.
These new boards are better then s9 boards.
Since I am an idiotic stupid moron that can't solve complex math or code very well I have to reduce myself to simple mechanical ideas and designs.
Once these are made maybe the firmware is tweak able and can be improved upon but I simply don't know any thing about firmware for the new gear.
I can operate it I can screen shot it. Playing with its code is far beyond me. I simply don't know how to do that. In fact I don't even know how the mining code looks like.
I don't know what the developer did.
So I am not sure if it even uses cgminer or bminer or another firmware.

I think this is the his firmware which he now gives for free according to the information he added to the thread > https://bitcointalksearch.org/topic/exploit-antminer-s9-and-t9-firmware-asicboost-original-moded-free-release-5127323
Despite the doubts raised by respected member Kano, I for some reason think that thierry4wd was honest about not altering the bmminer (aka stolen and modified cgminer
) and he somehow patched it and got full control over frequency and voltage, I tend to think that thierry4wd is a trusted member who puts a lot of effort for the mining community.

Love your project.
Do you have a link to your firmware?
Thank you.
Yes i totaly agree by this !
but on this mod, the pressure is very low! so, absolute not noise by holes, only litle noise by fan

Is my idea
two side, so 8 new holes arround 20mm i thinks is good size i have expected air flow, and up and down the flow is litle down, so by 8 news litle hole (not to big to respect the pressure) compensate this "problem" for more efficiency Can't see pictures but here is something that may be interesting for you to know:
Consider using a dremel to make non circle holes (such as square or octagon). Circles make more noise (like a flute).
Just remember: to reduce noise, avoid circles.
Someday i will try your idea, when i move to a country with actual winter.
[...]
Yeah ! absolut no problem !!!
if you find better idea i take this with pleasure !!! so i don't a god So, for proof, i have take directly my finger at heatsink !!! VERY COLD at center lol (normal ! is directly in enter air flowing !)
and for fan direction, i thinks my solution is better, i don't tell this so this by me, just i thinks is best idea...
For fun ! overclock at 800mhz/930mv (hashboard come by 13th model, bad efficiency) by fan fixed at 100% , just look temps ! :p and at this time, i have removed fans, in running mode, and i touch the headsink, and, is not to hot
(ambient temp is arround 20c)Ps : i have release my personal firmware for free for all, if you want try and take critique
your purpose is true only if the hole is smaller than air flow debit ! the proof is here, temp is very low on my configuration
Temp is low might also be due to a few other reasons, having a single board in the miner is a huge advantage, also I am not sure where the temp-sensor is exactly located, if it's far from the middle, then the reading can be way too off , if i am not mistaken the temp sensor is somewhere near the edge of the board (exhaust side), so in theory, temps in that middle part which i am worried about could very likely be a lot higher than what shows on the miner status.
Please don't get me wrong , I am not underestimating your abilities, I know you know much better than me in this field, I am just trying to discuss potential issues which might require some tweaks.
Thanks.
right now i am monitoring the solo.ckpool super rental trying to squeeze every dime i can for the ten of us in it.

your purpose is true only if the hole is smaller than air flow debit ! the proof is here, temp is very low on my configuration
with my design, the hole are sized in fonction, so, if you turn the fan at full speed, ok, the hole is to small for this, but not interrested by this, my idea is make small pressure, just for good flow, at low speed fan
ps : Philipma1957, you have try this ? what results ?

ps : Philipma1957, you have try this

That's an amazing design indeed, however, I have one concern which is the pressure on the fans' motors, I don't know much about physics and airflow, but I think when two fans are pushing air in the opposite directions they will collide with/against each other thus effecting the air flow specially in the middle area.
to illustrate more using your design.

Are both fans exhausting: drawing air in, over the board, from the drilled holes?
I think 💭 a few holes on each side may improve even more.
maybe a little smaller. lower 1/3 from intake
higher 1/3 from output.

Hum... after reflection, i thinks, is possible to improve efficiency of cooling, by make 2 litle hole (arround 20mm) at two side...
In this "project", my idea is make directly flow at center hasboard, but litle problem, the up and down chips at border hashboard is litle more hot, is not a problem (miner show final temp by chips 63 i thinks), but just funny to improve this :p

I don't have access to my philipma1957 account and this one does not have any merits.
When I get to my philipma1957 account I will drop some serious merits on this.
your design is way better then mine .
I have a s9 to work on I will do so later today.
I will do a copy of your design. Nice work. Cheaper then my idea and easy to do. Nice!

Hi all, i try to recycle part of miner ...
I have take all parts, is funny :
-T9 case
-T9+ controler
-S9 hashboard
-My custom firmware (but compatible with LPM for exemple or other)
I try at :
-525mhz/850mv (max temp 62)
-700mhz/910mv (max temp 80)
Just look fan speed and temperature , ambient temp is arround 22c , Very good resultat !!! and very low noise, the psu make more noise :p, by very low cost (free) just make 2 hole (arround 50-60mm)
Just for precision, on my "calculs' is very important do no make more larger of hole for assure to make air pressure at center hashboard at low speed fan, make hole at perfect center of miner at two side (look picture, so in absolute, juste turn the "in" fan).
For finish, VERY IMPORTANT, air flow for the two fan point external... so, air flow take on miner ant outake external ! the fan blade need place in interne... just see picture ! for assure, on power on, the air need to outake on 2 fan ! no admission, admission is NOW on two news hole !
And, VERY IMPORTANT to, you need TWO SAME fan !!! if not, the air flow is not correct, and is possible one part of hashboard is not in air flow, and overheat !
