A suggestion for a shed this size would be to put an Air Conditioning unit in it. They have some really efficient portable systems now and the one I am installing in my shed was only $1700 for a small HVAC with filtering capabilities.
Thanks! I'm trying to get more consistent with uploads. There just hasn't been a lot of content worth filming lately. Yes the shed has been running the whole time! Nothing has really changed besides a fan replacement and a couple fuses and filter cleanings.
Thanks my friend! They're working well even with rigs on both sides now. Still only running one fan, use the 2nd fan in the summer when it's really hot.
Hey thanks for the video. Can you please tell me the exact Outlet you chose and the cord that you got that allowed you to plug in to the wall and then adapt it to the very strange power cord? If you could actually tell me the model numbers so I can buy them that would be great!
Hey! I ended up using NEMA L6-30R receptacles. I had cables special ordered from Anen which is the supplier that builds the cables for Bitmain. The cable is a L6-30P TO P13 SJT 10AWG*3C. This was a custom cable I had them make so they were $50 a piece and then I had to pay $50 shipping as well. Here's the email for the sales team that can get you the cables ordered sales@anen-power.com. Let me know if you need anything else!
@@keisenb is it true that these machines should be wired for 30 amps? Or 20...? Getting conflicting information...do your power cables both handle 30 amps to the power supply pins?
Thanks! Electric rates range between $0.06 and $0.11 depending on the time of the year. I’d say an average is somewhere around $0.08 or so across the year
@keisenb dang that's pretty good. When I was mining here in NC was bout 10 11 cents. Became to unaffordable. That was 2 years ago. Hashrate was lower, and it was a 104ths, but within like 5 months, it became un affordable. That's awesome.
I have a suggestion, I have 2 mining locations with asics and I have them slotted into a hot room as-well, but it looks like you don't have the PSU slotted in. If that is true not only is your psu not venting but it is getting hotter and heat soaking your room more!!
@@keisenb yeh just grabbed a s21 for 5k with free hosting and 0.08 p/kwh electricity which is a third cheaper than running it from my home. Could rise to 20k and I can sell the unit or keep mining but even at 60k bitcoin just after the halving Im still making $100 a month profit from it.
Like your setup, I need to wire my plug I’ve been using 12/3 extension cords on ASICS and they start melting at connections. Make sure to knock out opening in the foam panel for the window for PSU before it overheats
My only concern with your setup is the cutouts for the asic fan do not extend to the outside of the psu vent holes on the back. I wonder if the psu is going to overheat.
Good to know. The only reason I say that is from my own personal experience of trying to install quieter high rpm (but not high enough) noctua fan and causing all kinds of weird stuff to happen.
Definitely would stick the PSU exhaust out into the hot aisle. It will make an impact on the in shed ambient temps. I know putting a hand behind the PSU doesn't feel like a lot of air flow, and doesn't feel like much temp difference when you're so close to the miner, but it will make a difference. I've seen miners is well known supposedly premium mining containers, burn out because the factory hot aisle shrouds did not encompass the power supply exhaust and PSU's burned out on hot summer days. If your outside air or air inlet was 40, and the shed ambient was 77, then there's a significant lack of exhaust moving and isolating to the hot aisle.
@@keisenb At the very least may need to consider underclocking units during daytime hot hours. I used an arduino to do this for me in the past because I was mining out of my attic, would underclock by 20-30% between 10am-6pm or so and then automatically overclock them throughout the night to makeup for the difference when the ambient temps were cooler.
Thanks! It was about 40 degrees Fahrenheit at the time of recording. It gets up to about 60-70 degrees in the middle of the day and drops to the high 30s low 40s at night right now.
im running mine on a 16 amp, i do have the njord board and are running a fan and a shrout plugged into another breaker.. but that just uses something like 130w on max that also removes that insane sound the s21 makes, so you can be in the same room
I ran all runs 10/2 with 30amp breakers and outlets. I knew that these miners are only going to draw more power. However its a pain when I'm only running 13amps on a 30amp run
I would build my own power plug from the hardware store with large gauge copper wire and a heavy duty 220-240v outlet. Just a thought, cheers and nice setup!
I'm currently working on that. I'm working with the supplier of these cords to build custom power cords with P13 connectors to the miner, 10awg wire and an L6-30p on the other side.
if you have a higher temperature insulation ( like THHN for example) the wire will carry 25 amps however I don't have that, and the NEC still only rates it for 20 amps.
oK SO, watched your video. Are you for real bro? So your upset because they changed the plug even though they gave you the right cable? WTF. You THINK it should have a 30 amp cable, on what grounds? Those machines draw 16 amps. They are using the 80% rule, you are wrong my friend. These machines do not require a 30 amp cable, a 20 is fine. Now that leaves the plug, I have zero idea why that's a big deal for anyone. Seems to me folks just like to get on the complain train. You have nothing to be upset about and you need to understand watts, amps and kilowatt hours. 3500 watts is 72 KWH per day, 3500w is 16 amps. So actually your upset comes from you not understanding power requirements and grumbling over a cable you didn't have to buy. Jeeze, your life must be pretty sweet if thats grumble worthy to you.
I will humor you and go put my nice tester on the breaker and check the draw with that. I'm pretty confident that my power meters are accurate within a small margin of error. All of the numbers make sense on my other miners at least. I would recommend you watch other peoples videos and take note that they also are seeing their machines run well above 3500 watts as well. And it's not uncommon for my voltage to drop to 230v at certain times as well, which would increase my amp draw.
Your lucky. I bought two and got sent 1 195th model and 1 200th model. The 200 only makes 198. Been running 1 month. Paid for 2 200th models. They are just dumping out whatever they have. Bought mine from crypto miner bros back in November.
Ah I just can afford the time to watch the video but why on earth isn’t he happy? I loaded about 50 of these a couple months back and they have been flawless.
They are drawing a lot more power than advertised. Gonna have to rewire my 20amp circuits to 30amp circuits and upgrade power cords. These are drawing anywhere from 16-20 amps depending on ambient temps
@@keisenb What’s your voltage at? Our single phase is a bit hot at 243V but a 15 amp breaker just about runs it a 20amp no problem at all. Most of ours are on 277V though and even a 15 amp runs it easy.

Hello, congratulations for what you do. One question, how much does the electricity cost kW/h?
Thanks! Electric rates range between $0.06 and $0.11 depending on the time of the year. I’d say an average is somewhere around $0.08 or so across the year
Where ya getting all this energy from if you don't mind me asking. This all residential? Prices must be insane if that's the case
All residential. I’m rural on all electric rate plan. Average price per kwh is around $0.08 across the year.

PLEASE try low power mode and sleep mode ? does sleep mode make it quieter ?

Thanks I actually just slotted them the other day from this comment and others!

My only concern with your setup is the cutouts for the asic fan do not extend to the outside of the psu vent holes on the back. I wonder if the psu is going to overheat.
They haven’t in the last 3 years so far. The PSUs output virtually no heat in my experience compared to the miners
Good to know. The only reason I say that is from my own personal experience of trying to install quieter high rpm (but not high enough) noctua fan and causing all kinds of weird stuff to happen.
Consider yourself lucky!!! They absolutely need the airflow to help the psu last longer!
They get airflow. It’s not hot behind them at all and air can escape with no issues
Definitely would stick the PSU exhaust out into the hot aisle. It will make an impact on the in shed ambient temps. I know putting a hand behind the PSU doesn't feel like a lot of air flow, and doesn't feel like much temp difference when you're so close to the miner, but it will make a difference.

Hey what is this miners? I mean what's inside of it? its like a gpu? cpu?
ASIC Boards
I wouldnt worry much about the 16.5 amp issue. If you really are concerned with it you can swap the wiring to 10/2 but it should be fine.
I'm not worried about it at 16.5 amps. I'm worried when it's 100 degrees outside and it's pulling 4100 watts and 20 amps

Why’d you go with crypto miner bros than Terra hash? Isn’t it cheaper at Terra?
I've never heard of terra hash and I know multiple trusted sources that have bought from crypto miner bros.

but that just uses something like 130w on max

The stock fans use up to 200 watts, which will make a difference, but probably not enough of one on their own.

Are you using the stock power cords on them? I ordered some 10 gauge replacements from the manufacturer that makes the stock ones
both, i've used stock and replacements. I don't know if I've ever had an issue with a stock power cord necessary @@keisenb
Can a L6-30 receptacle handle 2 s21s?
I would not suggest it, these are 3550 watts +or- 5% or that's 14.82amps to almost 16amps
Yeah I wouldn’t. They draw 16-20 amps so you’d trip breakers and risk starting a fire from melting the romex shielding.
no they pull 18.6 amps. Need 50amp. I just wired a 50amp. Trying to figure how to split
I would build my own power plug from the hardware store with large gauge copper wire and a heavy duty 220-240v outlet. Just a thought, cheers and nice setup!

I concur, build your own cables
If it’s rated for 20amps it can handle more. I wouldn’t worry about it. A 12/2 can legally take 25amps on a dedicated appliance
if you have a higher temperature insulation ( like THHN for example) the wire will carry 25 amps however I don't have that, and the NEC still only rates it for 20 amps.
Will 10/2 and a 30a breaker handle 2 s21?
