My S9 Heater version

[thierry4wd]

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

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

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?

[philipma1957]

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

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.
