I am a newbie. I just got in an Antminer S9 13.5T and after firing it up, it does nothing. Lights are on, but there is no Hardware Version or BMminer Version. I have installed the older version of software, ran the fix, upgraded to the latest firmware and still nothing. Is there anyone wanting some good karma? I need help!!
Thanks in advance!
Wait, what have you done? Can you show a pic of the miner's status page? |

Quick update, went back outside and measured the noise. It's as I thought, no difference between inside and outside DB levels. To be clear though, the ASICs are only 2.5' or so from the wall so the ducting is very short. Also these are venting in to a 3 sided carport, which turns out to be good as that insulates most of the sound unless you are in direct line of sight of the duct outlet. So, outside measurements are: 20' 65DB 10' 70DB 1' 79DB Roughly 40' at my fence-line looking directly at the exhaust outlet 55DB. Going the opposite way, with carport door closed and on the other side in my backyard 20' 45DB. For my location and township I am well within code and no issues with neighbors  |

Any updates on the 3d model on thingsverse?
I just hit him up, he's going to try to get it uploaded tonight. Sorry for the delay, but he'll do it, eventually |

Nice, someone doing it the right way. Just Kudos. I was just trying to explain this to someone else earlier today, it's like trying to reason with an hysterical kangaroo. Let me try this new merit thing on you. Edit: Seem like i can't send much but i did. Anyways, Good Job.
Thank you!! @caxibrema I will ping him right now. |

Thanks for the update. I bought some 8” insulated ducting at Home Depot last night. I’m going to do some longer runs. 8 foot or so to get the heat out of the room I have them in. I’m hoping the 8” size will allow enough flow at the longer length to keep everything cool.
An interesting test would be to do a straight run and then one with a loop to see if that could cut down on noise, but not affect cooling. |

Forgot to update, I went back in and performed sound measurements. No change on the interior noise, outside at the duct exits is another story. Heat's not the only thing making it out! Now granted my run from the miner exhaust to the duct panel is very short less than 3ft. but the sound outside is approximately the same as inside. I never measure before, but I know it was not anywhere near as loud. Interior measurements: 20' Interior Garage door closed ~ 45DB 20' @ interior door threshold ~ 65DB 10' ~70 At the miner 78-79DB Outside at the exhaust exit ~75DB, I need to verify this again. Last night seemed to be a cacophony of airplanes, Harleys, and dogs barking |

If you are wrong, you should say sorry to Halong Wink
No. Halong must blame ONLY themselves for the crap they are having being flung at them. They are the ones who chose to follow and furthermore continue to follow the Scamming for Dummies (TM) playbook for their marketing. So much they could easily do to undeniably show the world they have a miner and are capable of producing it in quantity and yet Halong is either incapable of doing that because the miner has not been able to move from prototypes/pre-production runs or for totally inexplicable reasons still just refuse to. Either way, Halong is getting exactly what they deserve here. First you told us everything is fake and a lie in here. Nobody of them is real. (Its proofed, you were wrong) There is no demo unit and no real video or pictures. (Its proofed, you were wrong) Demo units can now be visited if you ask them as customer (Its proofed, you were again wrong) Now you are telling us the pre-production story and that it is a scam - again you are sure   But that this part was already discussed in here before your brain-barf you totally missed. And the Inno-Comparision was discussed before in here, too. Haggsfin first got it in the thread - and he is right with it. Who is believing you anymore?2 times Halong proofed they are right.3 times its proofed that you are just guessing and lying around to damage a normal information flow in here without hyping its REAL or its SCAM. And btw I proofed all my stuff with picuteres and official site links. What is your proof? Steam and dust! You are just a bad human, a scaremonger and an alarmist with bad behavior and bad words. A lordly arrogant ... who thinks he is special. No. You are not. Even if this will turn into no delivery - you are wrong in your ways. Maybe you unlearned or you never learned how. But you are wrong! I don't know who you are or what your affiliation with Halong is, but damn you're going to defend them to the death aren't you? You are the exact mirror image of the people who say this is a scam. You are so adamant that it's real and go off on anyone who questions the validity you yourself have lost any credibility as an impartial proponent. You're either a paid sockpuppet, part of Halong, or a member of their cult |

hello all
so I have had my Avalon 741 running in my garage for now and have an s9 on order.
I go the conduit in the ground and should have electricity run by this weekend.
My concern is the intake and exhaust, I have an existing shed about 10x10 with a window in the back. I'm going to put a shelf right in front of the window and use a fan to pull the air out.
I need help figuring out what fan to use. I have a large vorando fan that I can use in the mean time, but id like to get something more permanent that will fit in the window.
The other issue is intake. I'm going to need to cut wholes in the shed for intake. can you provide any insight on the best way to do this. I will post pictures of my shed after work.
If it were me and the shed is dedicated for miners I would do the following. This kind of depends on size, but if it permits incorporate 2-4 large AC filters in one wall. Then on the opposite wall mount a couple of exhaust fans. I would go above the ~225 CFM output of the miners by 1.5-2x. So if you have 2 miners @ ~450CFM mount a 675-900 CFM exhaust fan(s). That should draw fresh clean air over the miners and the hot waste heat out. Obviously point the miner exhaust at the exhaust fans As you add miners simply add or upgrade fans. |

Ok I was thinking the 6” ducting would knock down the sound some. Maybe insulating the room would be a better idea.
I'll break out the decibel meter tonight, but I am pretty sure it had no impact. |

I might have to look into getting a few of those.
Do you know of a good sound absorbing insulation board? My miners are on a 3' x 72" tall shelving unit that you can get a Menards. What I am thinking about using is 1-1/2" foam board. I would put a piece on each side and one on the front of the shelf. The front piece would have a hole in front of each miner that the ducting can come through. Now the back is close to the concrete wall in my basement. I thought if I space the shelve about 6" from the wall and put a piece of that same foam board on the concrete behind it that I would still get some good intake air flow and the board would help knock down the sound. This is all in a room in my basement. I wanted to leave the back open also for ease of access.
I have not tried to quiet mine down. I would think if you have the space just build a small room and compartmentalize the hot and cold side within that. Then just work out the appropriate intake and exhaust ducting. |

Looking forward for the 3d file if you can get with your friend.
My friend will be adding the duct adapter to Thingverse, so just search for Antminer. It should be there soon. |

Bitmain not replying any tickets from over 4 days, just wondering do they take this much time?
Is this normal practice for them?
I noticed on Twitter that they are having some kind of sales meeting. If you have a Twitter account maybe jump on that and see if you can get someone to respond. |

On the dual 750 PS kit, will you be able to use the remote management? Also can you provide instructions for adapting this to a GPU rig? I *think* it's pretty straightforward, but I'd like to be 100% sure.

Most people dont size the duct properly for the airflow needed or they do not take into account the length of the duct. Think about it in terms of car exhaust. Mind giving some concrete numbers? For the antminer s9 for instance, is 8 feet too long? Also people will use inline fans that are not cfm matched to the amount of flow you are trying to create It seems the s9 for instance its around 200m 3/hr which translates to around 120ft 3/min or CFM. Would people generally assume linear growth? e.g. 10 miners ==> 10 * 120 = 1200 CFM? Just did a quick write up https://bitcointalk.org/index.php?topic=2796117.msg28582363#msg28582363 |

yes I absolutely will be, was just hoping to buy the PDU's asap. Our facility is part of a power plant so they have everything we need more or less set up already
L630P is pretty much the most common. But if you look at PDU manufacturers product catalogs I am sure there are others. Also don't ASSume you can get 4 miners per 30A circuit. Sticking with the 80% rule that would be right at 6A per miner, in practice they tend to run higher than that. YMMV |

seems like the only real solution is an expensive PDU
still doesn't solve the surge protector problem. i don't see any PDU with surge capability
Because if you read the previous posts you'll see that "surge protection" is largely a myth in consumer grade products. It's like the BS "Gold Plated" stereo cables on eBay... 1. Run the proper capacity breaker, wire, plug, and power cord. 2. Plug the miner in. 3. Profit. |

Very nice! I too am using the 6 inchers, on both sides though. I'm in the middle of building a Small room in my basement,
where I will draw in cool air from outside, and vent the heat into my HVAC system. In the warmer months, I will draw in the
cool basement air, and vent the HOT air out a window. On a 90 degree F day, the basement is about 65 degrees F.
Have you ,or do you, use any type of dust filter?
Thanks! I am not using any filters, this is all set up in my garage so the air intake is simply inside and fairly clean. From there it is blowing in to a 3-sided carport. Long term I plan on converting a small 20' X 4' (skinny rectangle) storage room for the miners I keep at home. The thin long room looks to be a perfect setup, it's at the back of my lot well away from neighbors so I can run some large CFM exhaust fans to draw airflow over the miners. In that setup I will definitely run filters built in to the wall opposite the exhaust fans. |

Can you give a more general idea of what you're doing with this? Is it just for sound or are you drawing outside air?
Me? I am just getting rid of waste heat. |

Be careful here. I would not use a 4in hose as the air flow resistance will be too high. It works just like a pipe where the larger pipe resist the fluid less. Same with wire carrying current. The idea you want is to allow full air flow but to absorb the noise at the same time. The sound will impact the insulation in turns but the air will flow around the turn easily. The sound wave is moving much faster than the air is. The larger the area for the air to move through the less restrictive it'll be. The more turns the sound has to make, the quieter it'll be. I prefer a 6 inch to reduce back pressure. I prefer 360 degrees of turns but 270 will generally do it if you need to direct the hot air a certain direction. The longer you make the hose, the larger the diameter must be to allow full flow.
Thanks for your input. But how do you mount 6 inch hose on antminer? Or you dont directly mount it on? |
