Topic: Powering case fans for a noise reducing enclosure (Read 340 times)
Nice setup! I still haven't finished my box to house all my units. Hopefully this month...
My understanding is that a neutral air pressure inside the cabinet would take care of overheating. Air intakes and exhaust will have to be channeled through foam lined fins in order to absorb the noise. At least that's the concept I see most commonly in designs of other people. Or perhaps, something like this :

My concern with all these setups is the close proximity to the enclosure wall. We are dealing with high-temperature electronics - don't forget! You want cool air surrounding the whole unit ideally (safety first). My setup is attached and is based on a YouTube example I saw. Half a year in operation with 0 issues and I'm overclocking 20%ish (setting 444 for the Antminer owners) to maximize profits as things gradually lower.

So how many 12v fans are you going to need to match the CFM of that many machines in one space?
Let the puppies breathe!
That being said and returning to the original post: Case fans are 12V. Miners are 12V. Would appear the answer to the original question is obvious. You should build a collection of common wire connectors with corresponding pins and practice crimping.
I've build 24x12x12" pine muffler boxes lined with sound absorbing materials similar to Rageprone's first YouTube link. Works great on a D3. L3s do not need them.
Delta fan blades are too loud for their CFM. Look for other high-power fans that move as much air while being quieter like Sunon Maglev fans. You still need to deal with the watts being pumped into the surrounding air space.

Hi all!
I'm trying to build a noise reduction enclosure for housing 4 units of D3 and 1 unit of S9. I want to go with a push/pull format for the enclosure using 5 x 120mm case fans for each side. Since there's no motherboard, how do I power these case fans? Can I use some kind of USB adapter to power the fans? I can't control the fan speed either but that's another problem for another day. Any feedback would be much appreciated!!

I've made a smaller setup for my single Antminer L3+ using a 5" shroud directly connected to the fans to ensure the best airflow to eliminate the warm exhaust air and to bring in the coolest air possible (currently outside as it is cold where I am from). Air is your friend, do not limit that but direct and redirect it safely. I connected the shrouds to a 5" insulated duct (home depot, 30 feet which you can customize for about $50).
For soundproofing, I set up a simple insulated box and used a 5" hole saw to cut holes for the shrouds to exit to keep everything tight and not collected the warm air within the enclosure. IMPORTANT, make sure the warm air exhausts or it will drive your Antminer to high temperatures very fast.
I hope this helps, feel free to message me and I can send you photos of what I used.
YOUR GOING TO BURN YOUR HOUSE DOWN

Well honestly, just go to KMART or WALMART and buy a bunch of 18" chinese fans for $20 each, and plug them in, and blow all the air out to where your wish,
Problem is sound enclosure your S-9 sounds like a jet engine, and so you would need 2feet of fiber-glass to muffle the sound, but to pass the fresh air in with the fans, you would need an open hole, where the jet engine sound would get out,
Seriously, what I do in this case with D3 & S9 I put them out in the chicken-house, err motorcycle-shop, and have a wifi-bridge talk back to the main-house, this stuff really needs to be OPEN,
I never put an enclosure on kind kind of miner, sealed or GPU, even a GPU card in a box, needs to have the cover removed, soon as you ensclose this shit it goes from 60C to +80C, best to run under 68C for long equipment life,
The ANTIMER BITMAIN shit is jet engine LOUD 90DB, U really need farm property, or an industrial setting to run this shit.
Some guys enclose them in boxes in their garage and exhaust, but still its awful loud and if you got neighbors your screwed
A walk-up attic with good insulation would work
Personally what I do with ALL miners is use commercial restaurant racks that are stainless and open grates, on each level have the 2ft kmart chinese fans blowing air sideways and in front of each gpu or s-9 have smaller 12v fans, these fans need 100ma, thus if you got 10 your pulling a full amp, and need proper power, most people just go to the junk yard and get old cpu power supplys, or hell buy a new one at frys for $10, the little fans can be had for $3,
But having the big 2ft/120cm box fans blow sideways on each level of rack is really critical
SOunds like your problem is a NOISE problem, and the main solution there is an external garage or chicken coup, or hell dig a hole and do an underground rig, thats what we do at BURNING-MAN we dig a hole bury the gas generators and you don't hear shit, lots of ways to contain sound.
But you don't want an enclosure unless you can MOVE massive volume of air, as you just asking for a HOUSE FIRE, ... IMHO
...
Summary power supply, just get used cpu, or buy cheap new, say 300w for $10, put a paperclip on the cpu connector so it turns on ( see internet )
I would not use mobile or common 1amp pwr-supply, they're not designed for fans, use a real cpu pwr supply so you don't have a FIRE
cpu power supplys have cooling and automatic shut-off, you need this,
You really need to fuss with ARDUINOS and learn how to control stuff these days, all the stuff you need can be got from an arduino kit relays and such so you can control your cooling/sound proofing over the internet with an arduino/rasberry-pi controlling your miners with a double-pole relay for each 30amp miner on 220v
