The room is 10square meters / 110square feet, not very large.
I understand. Water cooling might be my only option and buying the kit myself, piece by piece.
Thank you for your help and for your time, it really helped

Hello,
My situation is this: my rigs are in a closed rood with only two vents for AC coming in.
AC is stuck at 20C/68F.
The room is closed: no windows and no way for the air to get out.
The room also cannot be modified, since it's not my house and the owner has refused any modifications I proposed.
I can't move the rigs to another location. I need help/ideas in ways to cool the room.
I have a one S17pro and three T17+ machines
Things I have tried but have not worked:
fans with higher CFM/air pressure
big fans mounted right in front of the miners
giant stage fan to move the air around and cool all machines at once
connected one of the AC ducts from the ceiling to the stage fan to suck/push more cold air in the room: didn't work.
My last brain cell idea is to get a metallic rack and just put heatsinks on it and a fan to blast over them to cool the air since they aren't connected to anything, as in they're not generating heat.
That's about all I could think of and I'm out of ideas. Could someone please help me with this?

Got the S17 Pro, tuned with Braiins OS. Tried lots of other firmwares, this was the only one that did what I needed as in stable low power, heat & noise and fan control.
Details:
36TH/s
1,4kW
89C highest chip temp
55C highest board temp
55% fans
Looking online, these are within spec. As far as I'm concerned, it's behaving as expected.
Please let me know if something is wrong with the above. Until then, I'm enjoying finally having a working ASIC miner. Maybe next year I'll get another one.
Cheers!

@BitMaxz: Fixed with the fan simulator from Thanosminig. Their customer support&shipping was exceptional which surprised me considering the part was 5$.
With the 4 parallelminer fans running from the fan hub off the PC at around 3,500RPM the temps are holding at 74C which is not only half the speed and half the amps of the stupid YD fans, it's also half the noise.
I did a test run with the 4 fans at max rpm and they are still quieter than the YD fans not to mention they hum instead of screech.
Thank you very much for your help and input! Cheers!

@ BitMaxz : Thank you for your reply.
That's the thing, it's a non-standard T17+ at 58TH, hence my confusion over their standard specs. Both the T17+ and the S17 are listed at the same price and with the same 2,350W power draw.
Electricity isn't an issue right now but could be in the future. I was also leaning towards the T17+ but again, my goal is to run them at their lowest possible speed with the least amount of power draw.
I did have one S9 a few years back and I remember I could set it at low as I wanted, even at 1TH with the BRAIINS OS. Would the same hold true for these models also?
@sidehack : Thank you for your reply. Is there a difference in chip count between the T17 and the T17+ or are they the same?

Hello,
I've searched and couldn't find an answer either online or on this board
I'm considering buying either an S17 53TH or a T17+ 58TH but I can't decided between the two.
Both seem to be using the same amount of power 2,350W
Low power mode is what I'm after, with lower fans, temps and power usage.
In theory, the T17+ should be the winner but I'm not sure since I don't have the information.
Can someone please let me know which one of them can be set to use the least amount of power? I'll be using custom firmware for undervolt, auto-tuning and fan control.
Thank you

@BitMaxz:
I got this: https://thanosmining.com/products/ebang-ebit-e10-e102-e103-fan-simulator-full-speed-version
Description reads:
"Also suitable for models such as Cheetah F1.
Avalon 921 and other special interfaces are common to all series.
It works fine as long as the connectors are the same."
Takes about 2 weeks for it to arrive.
Thank you once again for your insight, I will keep you updated. Trying to get into mining on a budged is hard af, especially when you have to deal with all of this bs that just doesn't exist with Bitmain machines (less hassle, higher up-time, parts availability, knowledge etc.). Had an Antminer S9 last year with Braains OS on it and I thought it was hard but manageable. Oh boy, was I wrong...
As for cooling: I have 4 parallelminer fans + fan controller + a PC. Gonna mount the fans in a push-pull config, power them via the PC for control and for powering the fan controller.
I'm expecting that if at least the temps are the same, the noise will be way less. Mining software will be happy because it will "detect" fans, hashboards will be happy since they will be cool, I will be happy with the noise and the control part.
The fans that came with the Cheetah F1 were these: YD YD12038B2G 4.5A(GP)
They are 8k+ rpm fans. They screech, they are impossible to service and the vibrations generated from the rpm unscrewed the screws that were keeping them in place which is why one of the fans failed, because after noticing this, I tightened the screws more and since the vibrations had nowhere to go, the ripped apart the fan from its casing and it killed itself.
Better yet: at their peak rpm they push out ALMOST as much CFM as a standard 6k rpm parallelminer fan pulling almost half the amps
) These YD fans are literally broken, from design to finished product.

Unfortunately, I threw out the broken fan and the one that was left. Didn't want to use them anymore.
To eliminate the no-hashing issue: would a fan simulator work? I have fans powered through a separate fan controller.
If so, do you know if I use a fan simulator from the other brands or does the simulator need to be specifically for the Cheetah F1?
I found a Whatsminer M32 fan simulator kit locally, thought I'd give that a go, looks like this: https://i.imgur.com/eAwcMbY.jpg
I have a picture I took, comparing the broken fan to a standard 4pin PWM but you can't clearly see the wiring. From what I remember, seemed to be the same color-code as a normal fan.

Hello,
Can someone please help with this?
I just got a Cheetah F1 and it worked for 3 days after one of the fans failed.
Miner was hashing when the fan failed because:
1. Environment is cold
2. It has built-in cutoff at 100C.
I turned it off & replaced the fans but the miner will not hash, it endlessly loops with:
[10914.448044] gpio-20 (sysfs): gpiod_request: status -16
[10914.448050] export_store: status -16
in kernel log.
What stands out for me in the kernel log is this:
Comm: cg@fanctrl Tainted
Maybe bad fan connection or incompatible fans? Very hard to say, the only controls the miner has are: pool, reboot, operation mode - efficiency and performance. That's it.
Bellow is loop section of kernel log after 4h of "running" while not hashing. I have attached some videos of the LED error code also.
Normal operation LED sequence is: 1-2-3-4 then it starts hashing . Error displayed is: 1-2-4-3 short - 1 short & repeat.

My miner (Cheetah F1) doesn't seem to care if the fans spin or not, it hashes anyway (auto-shutdown at 100C though), so I think I can getaway with 2 fans on a Y adapter on one port since clearly it doesn't give an F about fan speed
If that doesn't work, I'll just use a fan simulator, a Y for one of the PSU cables so I can power the fan controller and go from there.
Please correct me if I'm wrong, I'm going on this by hunches. I'm not much of an electrician but I can splice a cable with a ton of black tape as good as the average Joe
Thanks again for your input, this will save me weeks of waiting on parts

That could always work as a last resort, thank you. There are also 4-ping molex micro-fit 3.0 (such a stupid name for a port, I swear) wires so I can always rewire them but wanted to take the easy, less-hassle route
My idea was to use a controller and with a supposed "adapter", split the two 4.5A fan ports into four so that I can run two sets of fans in a push-pull configuration.
The fans I have are rated at 2.8A so with a fan controller, I can keep that at 4.5A or lower. This way, it can run cooler and also way quieter. Was thinking of something like this:

Hello,
I just got a miner and it has these stupid YD12038B2G 4.5A fans which use a molex micro-fit square 4-pin connector.
The fans are WAY over the "65" db rated, the miner has no speed control for them and they spin at over 8,000RPM while delivering less CFM than a standard parallelminer fan.
Wouldn't be such a big issue if one of them didn't vibrate itself to death already, sheering off its casing because of the uselessly high RPM that also sent vibrations to the other fan and throughout the miner itself. I'm surprised the other fan didn't bite the dust too.

Can someone please tell me where I can find an adapter so I can use the fans I already have with this machine?
Thank you

I had the same error:
[ 13.660556] gpio-20 (sysfs): gpiod_request: status -16
[ 13.660564] export_store: status -16
Fixed it by doing this:
Unplug miner from power, unplug all cables, switch cables around when plugging them back in. For me, it was a bad connection somewhere.
Also, very important: check that all fans are working. If one fan does not respond, miner will usually not hash.

Hello,
I'm back with an update. Also want to mention that the room in which the miners are housed in has a fixed temperature of 25C/77F and is not something I can change but it does set a standard for a controlled environment.
All the kit I ordered from Parallel Miner has arrived and was installed. Sadly, the new fans only deliver on the increased sounds promise (which went from a loud hum to annoying, high-pitched howling) and nothing else.
1. They don't work in a push-pull configuration as in, you can't put two fans on one miner. You can replace either the intake or exhaust fan but not both because then the miner won't turn on anymore (does the full-speed fan check then turns it off)
2. They don't cool better than the original fans. Temperatures either stayed the same or increased with these TVN6100 fans, regardless if they were put as intake or exhaust fans.
Testing was done over a period of one week, testing each miner (13, 13.5 and 14TH/s) from stock to full auto-tuned and with swapping the fans from intake to exhaust and back again.
By sheer luck, I did find a fan configuration that works in a push-pull setup and dropped temps by 10C/50F while maintaining the same sound.
It's the SG121238BS + G1238C12B8ZP-C5. These two worked on all miners in both configurations.
Two good things came out of this:
1. I sold the miners: too loud, too power-hungry and way too hot.
2. Got cheap fans which I'm using to cool my other rigs and I can set them at lower speeds, solving the noise issue.
Thank you all for your input on this. I've learned a lot. Cheers!

For the moment, I got:
- 2x ZSX Fans Expansion Kit;
- 8x TVN6100;
- 2x 8 Way 4 Pin CPU Fan Controller Hub from Parallel Miner.
This way, I can manage my setup and depending on how it goes, can upgrade to the 300CFM fan in the future.
Temps right now with the fans on full blast are sitting at 99-102C/210-215F and no amount of cleaning and ventilation changed it so the fans are my last hope.
Thank you all so much for your input on this. Will post an update once I get all the hardware and install it.

@wndsnb: it's more than double the current of the stock fan. I know that deviations of 10% are ok but not 200%. Lets say I get the 300CFM one. Won't it fry the controller board if I just plug it in?
@wndsnb: Haha, we think alike. That's the same fan as I listed from Mouser. I can't find (yet) a dedicated, high power fan controller/hub for these fans. Closest thing I could find is the ZXS breakout board, which has lots of fan inputs but I can't find any output specs on it for the fans https://www.parallelminer.com/product/zsx-breakout-board-16-ports-pico-24pin-atx-fan-hubs-100-gpu-mining-a-game-changer/
also, this: https://www.onestopgrowshop.co.uk/products/control-freak-7-amp-dynamic-frequency-fan-speed-controller A bit expensive though and not very clear specs also
And yes, you are right: static pressure needs to be increased. The Delta QFR1212GHE has 29 mmAq; the Sanyo Denki 9LG1212P1G001 has 37mmAg, so a 30% increase but to no avail if the miner has issues recognizing the new fan. If I do find a controller, I'm definitely going for the big guns 300+CFM fans and I'm pretty sure I wouldn't even need to run them at full blast. Thank you for your input on this.
@NotFuzzyWarm: Thank you. I think I'm sweating the details too much. I'll just order the TVN6100s and experiment with higher CFM fans at a later time, when cooling isn't priority no.1

@HagssFIN: Thank you for the recommendation. From what I can see, the Delta QFR1212GHE has 211CFM, the Sanyo Denki 9LG1212P1G001 I posted had 247CFM. I was looking for an upgrade.
I am very limited by where I can keep my miners at least for now and cooling is an issue. The original fans keep up but barely.
@philipma1957: Thank you, I'll take a look. A shame the Sanyo fan doesn't work with the S9.
If I ever find a dedicated high power fan controller, I'll let you know as I was thinking of putting this on it : https://www.mouser.com/ProductDetail/Sanyo-Denki/9CR1212P0G03?qs=t9Lg9qrXjEzaIskuv0a4hg%3D%3D
Also: would this work? https://www.mouser.com/ProductDetail/Delta-Electronics/AFB1212GHE-C?qs=Tx9Tc1LIQ%252BGtXNKmVITynw%3D%3D
my guess is not, since it doesn't have a tachometer and PWM but I want to explore all options before I place the order.

Hello,
Will a 3.2A fan fry the Antminer (in this case, S9) control board?
I was specifically looking at this: https://www.mouser.com/ProductDetail/Sanyo-Denki/9LG1212P1G001?qs=ihlaDWZG8x483pqEdXadZw==
Also, if there is a dedicated fan controller for 40W+ fans (40W each rail), I wouldn't mind getting one of those but I can't find anything. All I can find are PC fan controllers and those units max out at 48W, as in the whole units maxes out at 48W, not each individual fan.
