The machines slide together pretty nice

you could link 20 or 30 on a long table.

but this linking has set back my soundproofing as it is too tight a fit to slide the muffler over the fan

I could dlink them to make room for mufflers see photo

I have to decide what I want to do.

200$ to take it down to 58 db is good but that next to your bed? Talk about not being able to sleep easily, I do like the set up a lot but the only real negative I see space.

it is going in the garage

that bedroom is a guest bedroom and the 220/240 power is easy access.

I am cleaning the garage to make room.

cost is 100 for 1 machine not 200

Okay more good news the controller runs 6 boards. I am doing it now .

Share the secret of what data cable ports to use and what data cable port left free. Or a picture.

Mine succeeds only 5 blades and sixth with ------------------------------------

give me a minute or 2.

did you a) check the cables maybe one is bad.
b) I could not get every psu to work I had to play around.

so check the power supplies and the cables.---- as I had that line of dots with the wrong psu's

So far I got an evga 1600 p2 and a seasonic 1200 plat the evga is doing 4 boards and the seasonic is doing 2 boards.

My highest setting has been 531.25 it works fine with this. oh the evga is driving the lone controller.

I am at ½ clock freq 300 as the psu will only give me 1600 watts max.

at ½ speed clock fans can go to 20% no mufflers needed 55db with decent pitch and temps are good.

Great idea mate!
~~Would it be "safe" putting the miner inside a bigger version of those ducts?~~ I could consider something like this for older ASIC's at a "stealth-mining site"!

Miners gotta mine! Cheesy

Edit:

Didn't see your "17 Inch Deep Rack Sleeve 4U", this basically answers my question!

I am going to set the second one up and try the rack sleeve as the draw in muffler along with the metal ones as the exhaust mufflers.

Setting the fan speed to 28% - 35% and the clock speeds from 550 to 612 will allow for tuning the sound.

Right now I am exploring super low clocks.

fans are 20% sound down to 47db at ⅔ meter and at 44db at bedroom door.

running under 12 volts void warranty I am running at 12 volts with the evga 1600 p2 I use 610 watts to get this hash . I will do 11 volts in 90 days I will do 10 volts in 90 days.

So far the temps are a bit high
I am trying to get under 60 with fans at 30%

  64-66 with freq 587 and fans at 30% hash is 4775 240 volts x 4.8 = 1152 watts or .241 watts a gh

  63-65 with freq 581 and fans at 30% hash is 4708 240 volts x 4.8 = 1152 watts or .245 watts a gh {note my pdu only does amps up to 1/10 so watts are off a bit}

63-65 with freq 575 and fans at 30% hash is 4646 240 volts x 4.7 = 1128 watts or .242 watts a gh

  63-65 with freq 568 and fans at 30% hash is 4598 240 volts x 4.6 = 1104 watts or .239 watts a gh

freq 568 is giving me 0% errors. but it is still too warm. I am going to bump fan to 32%

32% drops me to 61-63 0% errors

so freq 568 fans at 32% will do a long run. over night.

Now it is still warm in New Jersey. So once it gets colder I can run the fans lower. This unit has custom fan settings and custom freq setting. So with those of us that are sound challenged it is way better then the s-5.

So is your "all in" price about $200 to "muffle" one S7? Have you down clocked in any way, or is it running at stock speed from the factory?

no it was:

53 + 53 = 106 for 2 mufflers

2 bike clamps are 5 bucks

rubber is about 6

so 106+ 5 + 6 = 117 I had an ebay discount of 14% on the 2 mufflers so take off 15 = 102.

the mufflers will last longer then the s-7 so they will be a sunk cost.

BTW if you buy 2 or 3 of these S-7's you can link them on their side rails.

this allows for 2 of these http://www.mcmelectronics.com/product/555-17805 lined with this

http://www.ebay.com/itm/220659184713? one for intake one for discharge

this would do 3 units.

Also a very slight underclock to freq 575 would allow fans lower maybe 25 or 30% .

this is the next test I will set this freq 575 and fans at 25%.

I set it to freq 587 and fans at 30% looks too warm. db is 56 at ⅔ meter db is 51 at bedroom door.

240 volt evga p2 1600 pdu read 4.8 amps so 4.8 x 240 = 1152 watts and hash is 4779 so 1152/4779 = 0.241 watts a gh!!

Love the pics, Phil!!! Cheesy

Please stick a Vtec sticker on your S7 and make it a complete package. Grin

Phil: did you have to order 10" or it fit into a 8" enclosure? thanks
10" is a bit steep ($120), but 8" might be ok if it works ($80)

don't knock the importance of the rubber and the bike clamp as that decouples the miner from the muffler. My Hot air heat duct for my home has a rubber joint about 1 foot from the furnace it acts as a sound deadener. It is antoher reason why I used rubber and the bike clamps.

each muffler takes 4-6 db off so instead of 58 it would be 66-70db at ⅔ meter

yes, it is better this way. i wonder what would happen if the miner is fully IN the muffler...maybe less of effect in comparison with what you've got.
53-54 dB is fantastic!

six inch is good with the rubber and the bike clamps.

but 8 inch will just fit easy.

Since I had the bike clamps and the rubber I purchased the 6 inch mufflers.

the bitmaintech fans are about 6.75 inches on a diagonal so a 7 inch round hole works.

Any idea why they don't sell these "duct mufflers" at Home Depot?

they do

may be not that one but one of something and other HVAC Accessories that might be use full

how to get a round muffler on a square fan just use rubber pond fabric and a bike clamp

cost was about 100 usd for
2 mufflers 2 bike clamps 2 pieces of rubber

I did rhe same thing with a out side gas Generator sense it was to load to use were i live unless the power went out still do from time to time to save in the cost of Electricity but it really make no sense now to do because of the cost of gas it is cheaper using Electricity at one time it wasn't thu .

but nice you can do it with a S7 and keep the temps cool enough to run it at stock speed

taken while standing in the bedroom door

money shot 53db standing in the bedroom door
this is good enough for me. I am sure I can go under 50db but I do not need to do that.
