results are it is quiet.

at 60% fan which is more than 4000 rpm

freq 575

I am well under 55db

cost was 100 for the duct

I can make 4 more

I made 4

A wooden case the audio rack was free but you could build a rectangle open ended box for 10 bucks

and some duct tape 10 more grand total of 120.

to be fair I added some moving blankets and a pair of long sheets of mdf but they don't take a lot of extra sound off.

I will break the sound meter out in a bit.

finally got my two set up in the garage.

hands down the best solution is this. you can make at least 6 mufflers which does 3 s-7's

can not get this to show

You guys run 2 S7 on 1 Controller ? Why ?

If you have to ask why, this is not for you.

I want to use the S7 controller for 8 x S5 blade.
It is 1 x water cooled S5 4,3 TH/s. Winter is coming.

geez.. that is one freakishly loud miner.. heh.

Have you tried reseating the heatsinks ?

Are the chips sitting flush with said heatsinks ?

Have you considered lapping everything and/or adding a copper slab or shims to the heatsink ?

Why all the interest in the heatsinks? As I have seen the pictures, there is a small heatsink :)onto each chip. They aren't screwed down in any way. There is nothing to lap. It's completely unlike a CPU heatsink in terms of it's attachment.

It's a 1200W box that's got to get rid of it's heat, and it does so with high static pressure, high CFM, loud fans.

yeah and the only way to keep temps down it to let the fans do their job. So if you are not restricting airflow the best shot you have is a muffler system.

Now the 25 foot piece of duct work I ordered from Home Depot was 97 bucks. If it works well it is lower cost then the mufflers and it will allow me to send the hot air out the window. am looking forward to its arrival.

I am now running 2 pieces and the room is too warm since the night air is warm.

A two piece design needs to be diff. if you attach the machines the muffler will need to have a different adapter to accommodate the fans

I think you need to vent them out a window or something.

Nice work Phil. I'd love to see the two S7's on one controller at 600 freq Cheesy

need more muffler

found this at home depot

http://www.homedepot.com/p/Thermaflex-EverClean-7-in-x-25-ft-HVAC-Ducting-R8-0519-0700-0003/203767737

if this is better it is much cheaper

Phil, what was the dB reading before the muffler? I didn't see it listed in the thread.

stock speed 600
each muffler drops it 4db so 65 or 66db for 1 s-7 and it whines fan at about 35-38%

then 61-62 1 muffler

then 57-58 2 mufflers with stock freq and fan at 35%

it is warm in NJ 77f today if it were colder fan could go to 32%

all numbers above are at ⅔ meter

I am now running 2 pieces and the room is too warm since the night air is warm.

Sound proof will raise the temperature substantially and probably shorten the life of your miners. Just put them in the garage or something.

Sound proofing does not increase temps if done correctly.

I am not restricting air flow with the muffler system.

the setup works fine with one machine. with more then one it will need a tweak or 2.

easiest tweak is don't slide them to lock.

the mufflers will never leak water/coolant.
