Alright, total noob at this but I've heard it's possible to reduce the sound on an antminer using a silencer. Someone recommended me buying https://www.houzz.com/photos/58794924/4-Inch-Inline-Muffler-Noise-Reducer-Silencer-for-Duct-Fan-Air-Blower-Grow-Room-contemporary-gardening-accessories from here.

 Now the question I have is how much space does this take up?
Does it work on Antminer d3?
Do I need to buy something else to set it up?
Do I need some type of long vent tube thing? Why do people have these?
How much space would this take up?


Long Story Short, how can I get it the machine a little quieter. Willing to pay. Thanks so much :D

You can buy te ventilation mufflers but why not just put it in a well vented room at the furthest point from any people in the building.

When using such silencers, the airflow is reduced a lot and the Miner will get hoter - I would recommend to test this before using. Best way if no extra room is available is to put it in a box with with 2 hoses for air input and output.

They don't do much from what I can tell. They won't silence much and it's cheaper and more effective to just buy some ducting from Lowes or Home Depot. You'll be able to put multiple miners inside and it doesnt reduce airflow as much as those ripoffs. They're also cheaper.

Hmm, where could I buy such a box, plus what do you mean by 2 hoses for air input and output? I'm in a small room and never done that before? Like would the silencer reduce it from 75 db to maybe 50?

That is a big drop in noise level. It will be tough to achieve.Use a thick walled box and acoustic ducting. Remember the longer the ducting the harder the fans will have to work and the hotter the miner may become. You could use an i line fan on the exhaust to draw the hot air out but it would have to be quiet a high CFM rating which would in turn add its own noise. You can get quiet ones but they would be fairly expensive.

I'd be willing to pay but I'm not actually sure how things work? I've only seen youtube videos that look like people hook up pipes to a cooler? For example, you say you a thick-walled box and acoustic ducting but I'd have no idea where to get that at and how much space would it take up to have ducting? I'm in a small room and a huge pipeline coming through the room might get in the way too much? Is there not like a box or some sort I can just plop it into?

No mate uts not that simple. I used to have an S9 heavily underclocked (50% reduction) under my desk in my bedroom and it was bearable. No way could i stand an S9 going full speed. The acoustuc ducting is available on ebay or hydrophonics store. The box is just a regular thick walled cardboard box from a warehouse or packaging suppliers. To see what effct the box has set an alarm clock off and measure the level then put it in the box. It will give you a rough idea but remember the tone/pitch of the fans is higher so will carry futher/more.

buy these 4 things

the box the flex duct the tape ay home depot

the blanket at harbor freight

So cut two

10 inch holes in the box

put in 2 miners and a psu


tape the box shut

tape the flex duct for in and out

drop the blanket  over the box

cost 17+ 10 + 43 + 50 =  120  for 2 miners.

correct?

One question  a 10 inch  duct  will  allow good air flow for 2 s-9's or 2 avalon 741's  for about 8 feet correct?

  I would use about 3 feet of flex vent as intake   and up to 5 feet  as  exhaust.  

so the flext duct can do up to 3 boxes.

the plenum box will not catch fire  which allows for the blanket to be draped over it.

Harbor freight has a better deal on the blankets then home depot

you have inspired me to do a new design


this is 2 foot by 4 foot

http://www.ebay.com/itm/48-Board-Duct-Insulation-Johns-Manville-17635-/222077653881?

I will buy some of these and build a 4 ft duct  big enough to house 2 miners.
