Antminer S17+ x 6 in garage setup - help

[Rawbsoup]

Hi guys,

I wanted to start a tiny mining farm. I've got the correct power cables setup for covering between 5-6 miners in the garage. Due to not being able to run a lot of miners I thought I would go for the highest hash rate possible at 73th/s.

The garage is empty and I'm about to replace the garage door with bricks and a soundproof door and the single pane glass window with double glazing. The roof has been replaced and is water tight now.

I was reading about setups and it appears possibly building a shed 6' wide x 3' deep x 7' high with a wood between the units fans - to create the cool aisle and hot aisle. I would then need an extractor fan (50cm?) to pull heat out and I assuming need to put a hole in the wall to fan it outside. I need an air filter to draw air in (any recommendations?). I would put the s17+ on wire racks.

Could someone help with a bit more info or tips on a build. I am only making assumptions.

I started off with 500 in mind but after learning about amps and volts... realised this wasn't possible without a power station haha.

Thanks everyone, if I've been stupid please be gentle.

It's in the U.K. the calculations aren't great but to be honest, I just want to see if I could get it all setup. I would maybe at a later date move to GPU and altcoin. But I just don't want to burn down my garage.

Each miner is 2920w so is using 9,928 btu ? so 6 would be hitting around 60,000 BTU?

To be gentle you messed up terribly.

the s17+ is not able to run at lower speeds.

The s17 pro has three speeds.
43th
53th
57th
The s17 pro is the most efficient miner when set to low speed of 43th

My advice is sell your six s17+ units and buy seven s17 pro’s.

Good luck 👍

here is another way to calculate the problem.

6 x 3000 = 18000 watts which is over 60000 btu.

three speed s17 pro
7 x 2400 = 16800 watts
7 x 2200 = 15400 watts
7 x 1600 =. 11200 watts

[Rawbsoup]

I haven't bought the S17+, so you recommend the S17 pro's - Is this to save money on electric? Or another reason? I guess I can run it on low if the noise or heat gets too much?

the pro isn't it
Reference power on wall, Watt
1296 /  2212  / 2720   

confused about the
three speed s17 pro
7 x 2400 = 16800 watts
7 x 2200 = 15400 watts
7 x 1600 =. 11200 watts

Off the top of my head  I put those numbers down. I have so mnay units of different types I don't always remember every number.

the point I am bringing is  you have a small mine in a small area.

For the s17's
top power is say         2700  for about 57th 47 watts a th   this is the one I don't remember for watts

middle power is about 2225  for 53th = 42watts a th.       this is what  most of my 16 s17t pros do

low power is say       1500   not the 1296 they say but it tends to do around 42th  which is about 36 watts a th  which is the best any gear does.

you  have the ability  to pick and choose your speeds to help with power issues ,with heat issues, noise issues.

In  a small space like a garage  you are going to want more choice.

[Rawbsoup]

ah ok sorry I wasn't being funny just wanted to check my understanding. OK that makes sense to me. Allows flexibility for more conditions.

OK so assume 5-6 S17 Pro's -   
6 x 1296 = 7,776 w
6 x 2212 = 13,272 w
6 x 2720 = 16,320 w

With regards to the heat issue... would you recommend a unit being built. The garage I will board with sound proofing. Do I need an extractor fan to the outside? A filter bringing air into the unit. Make it air tight to force the filtered air in and have the extractor fan high up to take the heat out. Putting them on wire racks with hot side and cool side - do I need a board with holes in it to focus the fans to push the heat one side. How big should I make the unit?

[philipma1957]

one unit is about 450 cfm

six units is about 2700 cfm

you want at least 3000 cfm  maybe 4000cfm for extraction

2 of these would be okay to pull air out

you may be able to just use a passive  intake vent with air filter
2 of these

                                                     fan >>>>
   F
   i
   L     >>>>>  gear  >>>>>>>>> fan >>>>
   t
   e
   r

   F
   i
   l   >>>>>> gear >>>>>>>>>>>
   t
   e
   r

kind of this way

if box is

four feet high    six feet long    five feet wide

you can do low  vents side by side

you can do high fans side by side

you should use  6 20amp 240 volt circuits one for each unit.

most people do not realize that 80 percent derate is needed.

so .8 x 20 = 16 x 220 volt = 3520 watts max per line

full speed on a s17 pro does 2800-2900 watts.

so you have a good safety margin if you have voltage drops down to 205 volts. This happens in the summer often.

Electrician agrees its all setup. Got a carpenter who can build the unit. Stick the fans in the unit and vent to the outside. The filters can passively draw air from garage surroundings.

Thanks for the advice

How do you link the fans on the unit to the wall? Surely any tubing would get really hot? Do I need to put a board down the middle so fans from the s17 are all in one side?

No, you should go the other way around, especially when "beginning" and your ambient conditions are not clear. That is, use the most power saving feature you can, lower their rate so they can be efficient in power use and lower temperature, at least until you have everything perfectly set up.

You underestimate the amount of air a single S17 needs, let alone 6!!! I think maybe 300~400 cfm per unit, i have yet to know what's the exact figure for S17s, since i only remember the S9's 250cfm.

For filters i think those used for central ac units, the ones you can take out and clean with water, they are very large so don't be surprised. Yes, when thinking fans, and ducts, think large, as in wall sized large...

Hmm since you plan to remove the door, that could be the air intake, as that would probably be about the right size. Or maybe use those bricks with holes?

Wood is.. hmm i don't think very safe. Grounded metal should be preferred in my opinion.

If you think things are starting to feel "industrial", it is because that's what those asic miners really are. Its not just the power, its also the ventilation. Lone gone are the days of the humble R4 (or the S7LN), mine is still running in an actual living room...

What can I do? I have a garage 17’ x 8’ x 7’ I live in the U.K. I have 60amps spare and 20amp cabling plugs available.

What should I look towards?

Could I have one 73th/s?

I do have a decent size window I could replace with an extractor fan.

Don't bother in the UK even with a S17-Pro

With the VAT (20%) shipping and customs handling charges, just to get one miner into the country, your on a losing streak to start with.

Plus you are paying a load of cash to convert your garage!

Electric prices here are $0.16 per Kw/h

You'll make $7.82 a day mining bitcion, but be spending $8 a day on electric. Yes you could mine some other altcoin and make maybe $0.2 a day but that's transient, and by the time you try and mine enough to exchange it the profit will have gone out of it.

You need to host somewhere electric costs are like at or less than $0.06 per Kw/h like China, the US or Canada. With the downside to hosting in the US is the trump tax, higher import fees than UK VAT (27+%)

He could get 1 s17 pro   set it to low speed burn say 1.4 kwatts x 24 x 30 = 1008 kwatts a month.

he could point to  mmpool.org  or solo.ckpool

http://mmpool.org/   this pool give a bonus if you hit the block


http://solo.ckpool.org/  this  pool give you almost the entire block if you hit the block.


Mathematically  he will  hit a block  with 1 s17 pro  in around 18000 days  which is around 600 months  if a kwatt is 20 usa cents his bill is 200 usd a month so he would spend 120000 in usd over those 50 years.

I am leaving out  ½ ings and difficulty changes.

It is very likely he loses money. Unless he hosts or finds 'free' power.

I just want to mine lol I’ll do the s17 pro. I’ll just play with 2. I’ll get a unit built replace window with a extractor fan. It’ll need to cover 1,000 com?
