Howdy all,

This is a common problem without common solutions.  These S9s are crazy loud and I only have one with another to start on Wednesday! 

The only way to make a profit, which is ultimately how you sustain the BTC network, is to run the most efficient machines.  I currently run an S9-13.5 TH/s (https://shop.bitmain.com/productDetail.htm?pid=00020170124040658571l94rAg60064E) and the sound is driving me bonkers! 

What are some ways to keep muffle the sound? 

I've thought about sound control room dividers, acoustic absorption panels (https://acousticalsolutions.com/product-category/acoustic-panels/?utm_campaign=Acoustic_Panels&utm_medium=cpc&utm_source=google&utm_content=acoustic_absorption_panels&utm_term=acoustic%20absorption%20panels&gclid=CjwKEAiAuc_FBRD7_JCM3NSY92wSJABbVoxB3lWYekbxArbtZ09aJHNaSRvkgjBBKoXd4WLDGap1uhoCBOXw_wcB&_vsrefdom=p.4382&keyword=p.4382.9b7e1dfc-8f0a-4727-8049-b5423d87698d.cr10266) and building a little server room type box with an in/out that may be quieter.  I only have two ... maybe three in the future. 

How do you quiet the noise from traveling like a train throughout the house?

Thanks.

The short answer is you dont run it inside your house. Stick it an a garage or attic. The s9 is not meant to be run inside a home. Especially not the new auto tune units since you cant control the fan speed anymore.

I know philipma recommended using 12" insulated air duct to silence S7s. Would probably help with S9s, just not sure how much.  Take like 8 or 10 feet, cut a slit in it about a foot from one end, put the miner in with the wires coming out the slit, close slit and aim other end out a window or similar.
Never did it myself, went with R4's which are quiet but have reliability issues.

HTH, mine on!

Active noise cancellation.  Right now you can get yourself some noise-cancelling headphones that work quite well.
If you have all of your devices in the same room, you may be able to strategically mount a few speakers that will reproduce the inverse of the sound waves in that room which when broadcast should effectively cancel each other out and make the room silent (or at least a lot quieter).

 Maybe you can contact these guys - I think your setup would be much simpler and less expensive.

That is a great idea and would be a nice break every-now-and-again!

I ended up buying some of this; it's supposed to stop sound: http://www.nextacoustics.com/2-inch-soundtrax-acoustical-foam/ (http://www.nextacoustics.com/2-inch-soundtrax-acoustical-foam/)

From the site:


We'll see ...  :-\

Yeah I have a pair of cheap noise cancelling headphones (Sony MD5 I think) that I wear in my computer room.  They remove a modest amount of the constant background noise but then they were only around $40.  I know there are much better headphones for noise cancelling.

Curious to whether or not you have a garage.. i went straight from an S2 to an S7 and the S7 litteraly made me jump when it first kicked on lol. I ran it on the house for a few days and it was pretty much unbearable.

I ordered this and stuck it in he garage:

Here is a variation. (Im not familiar with this company though it serves the same purpose)

Litteraly internet through the walls. Plug one in and plug an ethernet cable from the router to the device. vice versa on the other side accept from the miner to the device and you have a hashflow. * <-- that, i like that, *hashflow* lol

Later i found that due the the warmer climate that i now reside in, temps were becoming an issue in an uncontrolled environment. Then came:

(Also vouch for them. They have a personal domain which i dont remember, but send a thank you note wih url attached upon delivery of pruduct)
Get an attachable tube from a hardware store and dump the hot air out a window if possible.

One last thing is the duct will cause a rise in temps. A buddy of mine, who gets a kick out of the nature of bitcoin surprised me with a good air blower to help with my cooling issues. (i would say this could cool two units if placed right and need be)
Good up to 105°F:

There are other, more affordable blowers, though they might only cool a single unit.

Sorry if this was a bit excessive. I'm really bored... and also trying to help you out  ;)

Thanks for your tips!


I don't have to worry about temps as I am in Montana in a basement. However, these are luckily placed in an area with an extra vent (currently plugged) to the outside if needed.


In line fans ... I grow peppers indoors, hydroponically, and when you get into HPS systems the lighting has similar issues.  You need lots of ventilation.  After my various years growing indoors, I have learned to get a grow tent (https://www.amazon.com/Urban-Farmer-36x36x72-Reflective-Hydroponic/dp/B01FIJECEC/ref=sr_1_1?ie=UTF8&qid=1488254411&sr=8-1-spons&keywords=grow+tent&psc=1) for keeping the temps in the 68 - 82 range year.  People either use the duct fans or a squirrel cage fan.  The squirrel cage is quieter, similar to the R4.  I bet some of the knowledge is transferable.  Like you said, you don't want to the duct work slowing down the flow - not only heat, but static.

Hey all,

The acoustic foam works okay.  I've been looking at generator boxes, but they are a bit of money and I am not sure how they will work.  I have shaped the acoustic foam into a "Z" shape for air flow from below and exhaust up. 

The thing the works the best is Bose Quiet Comfort 35.  I can turn on Netflix and not hear a thing! 

If I go larger, I will need to look at colocating (http://bitcoinasichosting.com/pricing) or building an actual soundproof room in the unfinished basement - though that will lead to ventilation needs.  ¡Ya veremos!

Any ideas to quiet bitcoin machine noise?

Immersion cooling (http://www.3m.com/3M/en_US/novec/products/engineered-fluids/immersion-cooling) would be extremely quite but likely expensive. You might try mineral oil immersion but you need circulating pumps for that which would add noise and potential failure points.

Some people also somehow break their miners running them in mineral oil, if you try this make sure you know what you're doing. Don't know how, but I've seen most miners submerged in oil running just fine before.

Good ideas..
Exactly what I was thinking of, besides the air blower.
I'll post pic and results when I start building but for now still waiting for parts to arrive.
A friend of mine mentioned it should be cooler with smaller diameter air intake and larger diameter exhaust..
Will have to test that theory

That looks cool, but I bet you are right as there are many different types of fluids and you need to contact them for pricing.  It seems like you would take the cards out of the S9s because you would not want the fans and the case would not be needed, expect for the control board.  

Edit: I wonder if one could simply take off the fans and submerge only the ASIC portion, leaving the top of the case exposed  :-\


Yeah.  I've seen that.  It's not for me at this point.  I'm thinking I may build a sound proof room with a dedicated main ... after getting a few more.

The Bose noise canceling headphones work amazingly well ...

You cant just immersion cool without figure out a way to fake the control board into thinking there are still fans running. The firmware is designed to shut the miner off if either of the two fans stops working. The trick is to not run industrial equipment like these miners inside your house.

Where do you run yours?

In a datacenter, which is what the intended use of these is. The only quiet home option is the super unreliable Antminer R4. As a side note I have found that the ebit miners are the quietest of all the 16/14nm miners I have worked with. Their firmware also offers the most control of the miner versus the Avalon and bitmain units.

Cool.  I've been looking at the datacenter option, but I only have two miners. My local co-location center wants $800 per month for a 1/2 rack, plus 9c kw/h.  I would need to have more miners.  I've looked at the firm out of Seattle, but am not sure about sending my expensive computers to a datacenter in another state.

If you are considering this option, you should contact sidehack (https://bitcointalk.org/index.php?action=profile;u=130792). I had 4 Asicminer tubes sent to him unassembled and he did the rest. I was given an option to rent or buy power supplies and I paid a small monthly connection fee plus $80 per month per kw. He even sold them for me once I was finished with them. Check out his sig for up-to-date information.

Sweet!  I may give that a shot because I am thinking about cashing in my 401k and moving to the tropics - where mining isn't an option because of inconsistant electricity, at best.

Seems like quite a ripoff when I recall that in College Station around 2010 or so, the "all bills paid" apartments started at around $700/month. (Apartments without utilities included started at $500/month at that time, although then there's a ripoff $40/month or so service charge.) I'm pretty sure there are places way cheaper than that.

What datacenters give you is bandwidth, which you don't need very much of for Bitcoin.

As for back to the original problem, do you have the room to build a shed in the backyard?

I'm sending them out to Sidehack who does some small-scale hosting with a good price.  I'll let ya'll know how that goes ...

Ask any musician with a home studio ....Lots of empty egg cartons..backed by heavy fibre curtains blankets... acoustic attenuation/dampening is just SOOOO easy to do cheap..
Every major city has office reno contractors that will be happy to give you old stuff they were throwing out anyway. scrap insulation helps too..

I sold my R4 and wish I didn't because it was the perfect heater/miner. I hope Bitmain or someone will make quit miners for home, great way to heat the house while turning a profit rather than paying for heat. I gave up trying to keep S9 in my garage, it gets too hot in summer so I have them hosted with Giga Watt. When winter comes though it would be great to have a quit miner for in home mining.
Some good solutions in this thread but I'm not sure they are good enough, I'd prefer just buying an R4 again.

I am currently struggling w/ the exact same dilemma..  I live in Georgia, where we have HOT summers, sometimes mid-to-high 90's.

Here is my current idea.. I have ordered a rack-mount setup for my 2 S9's that are on the way, but instead of just mounting these in a traditional server rack enclosure w/ side panels, doors, etc.. I'm going to mount in a rack frame (https://www.amazon.com/StarTech-com-Adjustable-Server-Cabinet-4POSTRACK42/dp/B00HVKOPBW/ref=sr_1_8?ie=UTF8&qid=1512998380&sr=8-8&keywords=Server+Rack (https://www.amazon.com/StarTech-com-Adjustable-Server-Cabinet-4POSTRACK42/dp/B00HVKOPBW/ref=sr_1_8?ie=UTF8&qid=1512998380&sr=8-8&keywords=Server+Rack))

Once I get that done, I am going to build a box enclosure from regular wood from the Home Depot :)  Plan on cutting at least a 10 to 12" hole in the top for exhaust to evacuate, duct it with 8-12" duct piping from the top of the enclosure, along the top of the garage, and pipe it to exhaust through one of our decorate vents on the front of our home.. This way, no additional holes have to be cut in the house, I can simply vent through an existing vent.  To assist with the exhausting, i'm going to add in a vortex fan inline (https://www.amazon.com/Atmosphere-S-1000-Vortex-S-Line-Ultra/dp/B071FGNR5Y/ref=sr_1_3?ie=UTF8&qid=1512998563&sr=8-3&keywords=Vortex+S (https://www.amazon.com/Atmosphere-S-1000-Vortex-S-Line-Ultra/dp/B071FGNR5Y/ref=sr_1_3?ie=UTF8&qid=1512998563&sr=8-3&keywords=Vortex+S))

This should move enough hot air out of the enclosure to keep things relatively cool.  Another reason I want to build this box is to make sure all air entering has been filtered to avoid clogging of the heatsinks since this will sit in the garage.  So, I plan on cutting 2 traditional home air filter holes in both sides of this unit at the bottom, so air can be sucked through naturally, and filtered.  

And finally, due to hot summers, my plan is to cut 2 ports into the box, also at the very bottom, and add at least 1 (if not 2, depending on if the demand is there when summer rolls around) of this floor AC units (https://www.amazon.com/Tripp-Lite-SRCOOL12K-Portable-Conditioner/dp/B002XITVCK/ref=sr_1_2?ie=UTF8&qid=1512998708&sr=8-2&keywords=Server+Rack+AC (https://www.amazon.com/Tripp-Lite-SRCOOL12K-Portable-Conditioner/dp/B002XITVCK/ref=sr_1_2?ie=UTF8&qid=1512998708&sr=8-2&keywords=Server+Rack+AC)) or, alternatively, one of these at the bottom of the rack flush mounted on the front of the cabinet (https://www.newegg.com/Product/Product.aspx?Item=N82E16816228178&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Server+-+Accessories-_-N82E16816228178&gclid=CjwKCAiA9rjRBRAeEiwA2SV4ZWOkcto58CA2y6u2g5gcI0Ufw3l65lHWQwPtOxYUk3rVgzuMe7tbBBoClvkQAvD_BwE&gclsrc=aw.ds (https://www.newegg.com/Product/Product.aspx?Item=N82E16816228178&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Server+-+Accessories-_-N82E16816228178&gclid=CjwKCAiA9rjRBRAeEiwA2SV4ZWOkcto58CA2y6u2g5gcI0Ufw3l65lHWQwPtOxYUk3rVgzuMe7tbBBoClvkQAvD_BwE&gclsrc=aw.ds))

For the A/C units, their exhaust hot air can also be ducted into my exit tubing with T connections, so the ambient temp of the garage shouldn't be increasing due to proper routing of hot exhaust gases straight out of the front of our house.. With the AC pumping directly inside the cabinet, although it will be sucked quite quickly, I would imagine that would help keep the temps down where they need to be down (i.e., ONLY inside the box instead of trying to cool the entire garage, which would be a losing cause)..

Lastly, another reason to build the box enclosure is for sound dampening.. I plan on lining the box with dynamet or some other sort of noise suppressor that is heat resistant so the garage doesn't sound like an airport :)

The reason i'm considering doing this is I plan on scaling this from the two S9's I have on order, to several rigs.. I also have a 6 GPU setup right now for Ethereum that I may change over to a rack-mount chassis and stick in there.  Would be a good place for any servers down the line, etc..

Thoughts on the efficiency of the design?

*Only other potential option is scrap all that and colocate these, but with only 2, it isn't cost effective.. would have to wait until I scaled to 6-10 of them.

Thanks in advance,

Matt

I feel like you and I are on the same page, but I am taking the rack mount idea, and mixing it with the cooler ideas found on here and youtube.

I bought one of these that has a sliding rack inside

https://www.ebay.com/itm/Pelican-Hardigg-Large-ECS-RackMount-ShockMount-Case-Military-Container-Blk/232478519406?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 (https://www.ebay.com/itm/Pelican-Hardigg-Large-ECS-RackMount-ShockMount-Case-Military-Container-Blk/232478519406?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649)

and am adding soundproofing with 2" sound proof panels that are 12"x12" to the case. I will run 3 S9's inside side by side, PSU's outside.

I have 10" insulated vent pipe going in one side, and the 3 S9's will be vented out the box through connectors into more 10" vent leading out a basement window with the help of a 10" inline fan.

I will pose pics when I get it further along

Yea, sounds like the same basic idea, just different "vehicle" :)  How are you doing the filtering?  And are you doing anything with A/C, or just room air intake?  My worry is summertime in the garage.. Winter is a non-issue.

You will find the soundproof device for antminer s9 and l3+ to make your device without the noisy issue in your circle. With the sound proof device you will be able to keep your miner in your home or living area too.

Homedepot.com will be providing you the way to purchase it online.
Please watch the youtube video which can be used to antminer s9 with the below link.
https://www.youtube.com/watch?v=VbAjh5q1Tzw

Yes that is very close to what I will end up having, with my case being used in place of the cooler. 3 S9's will fit inside the case

I have the same problem as I live in a smaller townhouse.  I picked up a 5" shroud on eBay and 30 feet of flexible insulated ducting from Home Depot ($50) to redirect the hot air out of my house and channel the cool outdoor air inside the enclosure.  YOU MUST ensure the warm air doesn't recirculate into the enclosure which is why the shroud directly connects to the Antminer with the 4 fan screws on the back :)  As an enclosure, I used a heavier duty Coleman cooler (the keep cool 5-7 day kind, ghetto I know) and cut a 5" hole on each side to run my ducting.  It works well and brings things from 85 decibels to a calming 65.  Thicker coolers are insulated which suppresses the noise.  As in previous posts, you can see a YouTube video of how it is made but it does not mention using a shroud for that airtight connection!

Feel free to message me and I can show you photos and where to get the shrouds etc.  Tons of places on eBay sell them.

So how is this working, heat wise?

I may consider a collector in the top of the enclosure I plan on building with the shrouds+flexible tubing off each miner to the collector to vent.. The reason I hadn't considered this is due to the fact i'm going to have a huge vortex fan literally sucking the heat out of the enclosure at either 750 CFM or 1081 CFM (depending on if I go with 8 or 10 inch fan).. But, I suppose controlling the heat dissipation even further w/ the ducting up to the exhaust vent would only help keep things cooler since no ambient heat would escape for the most part.

Given that are the fans to make noise, isn't it enough to connect the two soundproof ducts to the miner without putting it in a box?

I've sound-proofed the entire room, but am going to expand and move to a warehouse.  That'll solve the problem.

What about the acoustical foam you bought? Worked or were useless?

I wouldn't recommend the acoustic foam.   It was useless.  I bought some Safe N' Sound for the room and, then, the air vents let sound through.  The Safe N' Sound is really good though.  I would use it, again, in the future and recommend it.  

I'd need to do more construction for what I need and am going to sell the home, buy more miners, rent a warehouse and spend more time in Central America.
