Not really.
The S9E is not 'recent', it has been out for 2 years and for the most part acts the same as all s9's. Loud and hot.
For at least the past 4 years all BTC miners have been the same - LOUD. The reason is simple - they suck a lot of power and need the high speed fans to give enough pressure to force air through them for cooling.
The only way you can throttle them down is through reducing the power they draw by running the miner at lower THs via undervolting/underclocking. Simply slowing down the fans or trying to replace them with quieter ones only results in the miners overheating.
Sorry, false, S9 4 years ago ok  but no S9K / S9SE , is probably running by 10nm chips ... So, control fan is possible and easy ! you just need SSH acces (please shearch how to) , goind to config folder, open cgminer.conf , and, add two line : "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" : "45", (so, change 45 by 0-100 you want) |

Ok, I think I understood, the firmware is loaded from the Sdcard and does not flash itself on the NAND memory, something similar to Braiins OS when it was first released, so what does he do if he wants to upgrade to a different firmware? I don't see this firmware running on an SD fixes any issue, what if he wants to use another custom firmware for an example, please explain more.
Yes, runing mode only, no write on NAND ... but, is unlocked, you allowed for upgrade (by web gui after boot) any firmware you want ! Im now not nearby the miners but Im pretty sure there is only the hole on the metal and no sd card slot behind it, or only the jumpers are missing to switch on the booting like from older s9 models  ...I may be mistaken but something is off, anyway, will get checked shortly and report here the outcome based on the tips I got. I'm sur, you have SDCARD slot !  the port is behind |

Sorry, my english is not very good ! lol old = not take off / not remove So, put the SDCARD (1go - 8go), power on miner, and, not remove this ! the miner booting by this sdcard |
|
|
|
No ... i have unlocked SSH acces, and see "bmminer" AND "cgminer" , two version is used on my miner  |
|
|
|
|
i have one T17, and contain CGMINER + BMMINER to ! original firmware, i have examined this, and, CGMINER is used only for running hashing, and BMMINER is user for booting / rebooting or apply config...
So, no problem, just stipide bitmain, mixed two version... if you delete only BMMINER, miner run good, but you don't want apply new config (pool for exemple) ... the code is mixed ...

Two custom firmware already exist, i have buy only one, and run good ! S9K up to 20TH but very high temp (or need very low temp local) ... I don't know if he wants me to reveal his name ... So i assure this custom firmware is good |

Hum ... your kernel log is very strange for me... i thinks used by custom firmware... is true ? Reason : your 3 hashboard is not same eprom read chain[0] hardware info:

thanks for yours tests and comment But is not my firmware, is just my "mod" for unlock feature on original firmware With pleasure ! |
|
|
|
Hi , if you need more speed by easy mod, just unplug blue wire on each fan if you want for fix it at full speed |
|
|
|
Yes ... if it working on Hydro series... just try it Try at "stock" value first |
|
|
|
yes i know but my, take only arround 1950 - 2000w and i see other member here take arround same config, and have 45w/th |
|
|
|
Perfect ... you running with "multi-option" firmware ? i have uploaded + instruction on first post my mod modified for all miner "9" series ... i pretty sur, running well just i want to test it on hydro you got no problem, no contain "spetial" files, only "text" files |
|
|
|
Working perfect on my T17 before 12/2019 firmware |
|
|
|
|
Very high performance ! anwesome !!!
but litle problem, at 42w/th showing 4200W !!! but APW9+ is 3600w max ... i thinks is very dangerous ! , is only my thinks...
|
|
|
|
UPDATED ! Please send your comment after test |
|
|

hey not problem ! I don't attack you  we are in same camp Just i tell my opignon ... so, i thinks i have very good T17 ... On stock, is run at 720mhz at 16.8v ... give me arround 45W/th ... 2020-01-31 19:18:15 power_api.c:96:get_average_voltage: aveage voltage is: 16.797558 2020-01-31 19:18:15 frequency.c:582:get_current_min_freq: current min freq 720 |

i have tested this firmware ... is not good for me, overclock ok, but why ? at stock my T17 run at 43.5th by 1950-2000w ... if i overclock, down efficiency, and your devfee is to high ... more power, more heat, same revenue... lol Why is the software called CGMINER? What reason my mod for S9 firmware are detracting and not your ? i don't understand ... is shame, even the S9 is old machine, you lost very good finding on this machine |
