Summer Mining - Fans/Other summer equipment

[philipma1957]

no worries it was nice to help.  I can not  believe that i waited this long to do some 240 outlets.

remember 12 gauge for  a 2 pole 20amp socket

10 gauge for a 30 amp 2 pole socket

I did one of each.

And my 12 gauge  is a 2 foot run from the main breaker box. so no worries.

I really like the pdu I linked you to price is good and it has an ethernet feature that allows any one plug to turn on or off.  (not going to use it but it is cool)

I mine in Alabama with no AC in my warehouse at work. I think my S3's got up into the mid 50's C last summer. That Lasko fan is what I use in front of my miners and then I have another big fan that is mounted on the wall to at least circulate air. Granted, that warehouse is at least 100F in the summer. Probably more.

smracer has a crazy setup to mine in Texas with no AC, but the dude has like $30k invested in intake and exhaust fans.

There is nothing wrong with the lasko it is a very nice fan.  The Utilitech Pro's I got are just hard to beat as far as the amount of CFM's they do.  I won't be spending near 30k.   As far as costs I have 2 shelves, 8 110 circuit breakers, a bunch of 12 guage wire, reciprocals to hook the wire's to.  Thanks to philipma I will be adding 1 240 to start with. 

I still need to take some before pictures (and clean it a little).  Also I would like to measure dimensions if i can find my big tape in the garage.  Hopefully this weekend alot of it get's done.

I guess it's time for a project update.  At this point it's getting lot's of parts I have.   

• Got 2 shelves to hold miners
• 8 - 20 amp breakers/a bunch of 12 guage wire/reciprocals/reciprocal boxes
• Some non-conductive screwdrivers (and this subpanel can be turned off completely during wiring
• 3 Fans, 2 big fans, 1 medium (In addition to vents already installed and one nice 15 inch duct using a fan to exhaust out)
• 220 PDU - SERVER-TECHNOLOGY-SWITCHED-Cabinet-Distribution-Unit-CDU-PDU-CX-8H2C211

Parts I still have to get

• 220 Reciprocal, and 10 gauge wire, and 30 amp breaker

So it's getting there hopefully this coming weekend some progress will be made.  And a special thanks to philipma1957 for his help on 220.

Ahh your are lucky you have a nice place to set it up…
 Have you looked into solar down the road not now.
better yet a wind turbine?
also not now down the road.

Having a lot of land is cool. I had an uncle with 220 acres .

I did kinda luck out into having lot's of electricity.  They wired it thinking it would be used farming. I have 2 power lines coming in the main house has 200 amps just to it, and the newer garage has a subpanal with 100 amps pretty much will be just for mining now.  And with it being family farm house, it has just gotten bigger and bigger over the years.  And ofcourse the garage/work area that I will be putting miners above.

I looked into solar, it was to much front end cost to justify with .095ish cents KWh.  I have not looked into wind turbines as of yet, all these old country family homes are kinda slow on newer technology so haven't seen much of them hit here yet.  I would love to have it, but upfront cost just makes it hard to justify.

I enjoy the land it is a lot of fun.  One thing I love doing is target practice so it allows me to do this safely outside.  Only bad thing is neighbors are a decent ways away.  So for security we have camera's streaming and and also a pretty good security alarm system.  So between those it will keep my miners safe.

Kinda on hold for a day or two.  I'm getting a upgrade from regular dsl to a fiber line.  This is not for mining I was mining fine at 10 Mbps to hopefully 50 Mbps.   So far above what is needed for miners.

Hopefully if all goes well I get it installed tomorrow they have cable close so install should be in few hours if estimate is right.   If this goes through then I can focus on my new mining area again.

[notlist3d]

Fiber install was successful.   A thank you to the goverment for somehow making it where the internet company made money laying fiber to farms.   It is amazing the amount of work they put into this project.  It was pretty much all last summer.  Now they are just starting to use it.

I now have a 50 Mbps internet connection.  It was not needed in anyway for mining, but I wanted the bump in speed.  So far very very good choice.

[notlist3d]

Have been working on getting parts. philipma1957 has went above and beyond.  A special thanks for his knowledge of 240.

Now a few more parts to order.

[notlist3d]

On 240 I was starting to get a little confused with what to run to the reciprocal.  Thanks to philipma1957 I know what will work.

I have 10-2 that will do 2 hots and a ground for the following reciprocal:

I was a little confused between 10-2 and 10-3 was my problem.

[notlist3d]

Tomorrow I will be working on it.  Don't know how far I will get.  I'm hoping to get done this weekend, but it might draw into next weekend.

I WILL be taking pictures though tomorrow to document it.   So pictures to come tomorrow night chances are by time I upload them.

don't rush it.. a 240 volt 30 amp line is  7200 watts   vs a 120 volt 15 amp line at 1800 watts.


once you think it is done use a meter on the


 l6 30r   

  the 2 hots should read 230-242 volts

  1 hot 1 ground should read 120 volts

 the other hot with the ground should read 120 volts.

once all 2 readings   check out  then plug in the pdu it should light up and read 0.0 for amps

If all that works check the sockets in the pdu 2 hots should give you about 230 -242 watts  1 hot to the ground around 120 volts

you can then plug in the psu test just the psu with   your trick switch  (paper clip whatever you use)

all that works power off the psu and hook 1 miner up just run 1 miner if you are using a avalon 4.1 at 900 gh or so  that is about 500 watts or 2 amps on the  pdu meter.

after that load the mofo up. and hash away.

Thanks for the advice.  The 240 did originally scare me, which is why at first I had a electrician drop a quote on it.

I got lucky that this is a subpanal, and has a switch by the meter the shuts down the entire thing.  So when it's being wired no electricity will be live.  And it will of course be double/triple checked and still treated with respect.

[notlist3d]

Taking time to do it right.  Got 4 110's done today.   Set up and running good.

Pictures to come later today.

[notlist3d]

Been one long day.  Being safe takes time to say the least.   I will post just a few pics tonight.  Eventually I plan on making a new thread and clean it up/make it more readable.

Front currently showing 1 1.5 T Dragon, 2 Antminer S4's, 2 SP20's, and 1 S5.

Back shows the 4 wires that are currently wired:

Network is messy it will be cleaned up and ziptied to look nice in the end.  To go is 4 110's and 1 240 on wiring.  And yes it could have been easier with all 240, but I just am use to using 110 and had the room so I did it.   

I am pretty tired after a day of this, if I wake up with a ton of energy I will do the rest tomorrow.  If not it might happen this week or next weekend.

[philipma1957]

Thanks for photos.  I see one fan up high.

I see one near the 2 windows on the floor.  I know you have more.

 I like the plastic shelfs vs metal.  lowers short risk.


you have about 8th? at 5k watts?

1.5--------dragon
2.0--------s-4
2.0--------s-4
1.2--------sp20
1.2--------sp20
1.2--------s-5


I know you have 2.6 with 3 avalon's

that is over 10.6

You may need a second hole for another fan on the high fan side not the window fan side.

Thanks for your advice it is always appreciated.  I need to take a few more pictures now two big fans are set up, and one smaller one by window to help cool air push in.  Once I move more miners in there I will have another fan to put by 2nd window to help push cool air in.

When It's all said and done I should have (some are underclocked):
Miner         watts        no   total watts
S5                 580      1         580
1.5 Dragon     1100    1       1100
S4                 1400    3       4200
SP 20             643     2        1286
c1                  800     2       1600
Avalon 4.1       549    3        1647

          total watts   10413   Speed is normally high 15T's.

  Nice last winter I had 12  sp20's 1 s-5 and 1 avalon 4.1

   14 pieces  had to underclock them as my power envelope maxes at  7k.

Now with the 2

 240 lines

 I can do 10k easy power wise this coming winter.  but that may never happen.

Yea I'm kinda slow at adding compared to what I once was.   I was over 12k during winter using free cooling from weather.

But I got rid of my S3's and my A1 1T Dragon.  I was going for more efficient gear.  And planned on going down even less but it just didn't happen.

[notlist3d]

Been testing my new area with just the gear in it I showed.  Going to take my time and slowly get rest of it wired.

I had a problem I did not think I would have.  During night with my 3 fans (I still have not put 4th out there) it gets so cold I don't need near what I'm using.  During day it still seems pretty nice in there considering amount of watt's air exhaust currently working good.

So now I am left with spending to much on fans at night .  I either will do a timer on some where at night they kick off and don't run them all.  Or do a more advanced fix where it turns all off at certain temperature and flips on over that temperature.
