good then this is better than I thought. It will cool 2 m30s+ with ease. Even if I run them at high speed.

do you have this psu?



https://www.amazon.com/gp/product/B07FG81F7H/ref=ox_sc_act_title_1?smid=ARSL1YBVZEIA9&psc=1



if you do this cable works

https://www.amazon.com/gp/product/B0012EI6KE/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1


but you will need to run the s9 at lower clocks as that psu does not run well on 120 volts.

I have found that particular psu will work to about 1000 watts on 120 volt power

so you will need to clock the s9 to about 10th

Well I don't know the quality of the liquid cooler.

2x 30s+  cost me 3200

2x 50 would be 5400


SO if the cooler sucks I save 1800 maybe 2000 buying the 30s+. which is the cooler cost.

If the cooler is good we will likely get 10 more and use m50's in them


If the cooler sucks we will likely go back to s19j pro gear.

m30s+ = Investing 3200 + 2000 = 5200 plus import taxes .

m50 = Investing 5400 + 2000 = 7400 plus import taxes.



going all s19j pro I can pay 1776 for 1 includes all so 4 x 1776 = 7104 for all truly cheaper but my cooling issues won't let me  max with air cooled gear.


we have 1.7+ .8 = 2.5 ph for btc     we have power for 25   3 kwatt units we don't have cooling

Also I know 'buysolar' can use this cooler in his home he has a 115kwatt solar array so this will work in his house if it is not good for the farm.


So bad cooler means s19j air cooled

good cooler means m50's and maybe 6-10 coolers

@ mikeywith yeah there is a bit of gear fomo 100th miners were selling at 15k they are now under 2k A lot of people like me with good cheap power but other issues (cooling) are buying.

I did :

I don't mind if I am short of 200th and end up selling a 180th machine burning 5800 watts.  

The key with the unit I am using is it is a 2 whatminers piece. The cooler has the ability to heat in the winter and warm a pool in the summer. My partner "buysolar" has been doing solar setups in New Jersey for 20 years. We may work the angle a few ways.

Also we may do a single whatsminer m50s+ overclocked if they supply a proper psu to do that.

https://www.whatsminer.com/src/views/product_details?id=15&name=WhatsMiner%20M50S+


what matters down the road  is how good the cooler is. It could be a bust.  which is why we got the m30s+ to test it just in case we don't like it.

what I have found interesting is:

'normal' and 3100 watts = good
'normal' and 3050 watts = good
'normal' and 3025 watts = testing now>>>> edit :

 now doing:

unit 1 >>  92.509 th 32.56 watts a th and 3011 total watts
unit 2 >>  92.490 th 32.62 watts a th and 3017 total watts


'normal' and 2950 watts = fail
'normal' and 2900 watts = fail


this is not to complain but may mean the cooler will struggle with 2 m30+ on normal and 6100 watts.

Typical designed just a bit wrong and yet they push 2 whatsminers as a fit with the cooler.
Likely need a quart more liquid and a little bit bigger radiator to be perfect


now on low setting I did 88 and 2875 watts which is 32.67 and 2 of them would be about 5750 watts.

so low setting may be needed for the coolers.

I will post back to see if I can play with settings a bit more.

Maybe with a day of burn in I can set lower than 3025 watts on normal.

Not so sure how those kickbacks are done that kano refers to.

Back to setting up a mw mine.

you need at least 2 large transformers. say 1mw each

https://www.larsonelectronics.com/product/283719/1-mva-pad-mount-transformer-12000v-delta-primary-480y-277-wye-n-secondary-knan-doe-efficiency-rated

they are 187000 each btw you need them for the containers and or an in-house mine.


So lets say we do not count that for a miner in the warehouse or the containers.

the ware house will need large breaker panels.

maybe 4 1000 amp panels doing 480 volts

https://www.ebay.com/itm/374381242913 these are 20k each or 80k

you then need to break down to sub-panels.

and from the sub panels you can do pdu's and short cables or outlets and long cables.

translation is serious money to do the warehouse correctly.

and time to get parts.


or buy something like this
https://shop.bitmain.com/product/detail?pid=1845021123118285350583K2a0P505EF

cost 110k get 3 of them. and under stock them and hopefully cheaper faster and some redundancy .


If I had the money to do this I would got that route.


how cheap is the power you have?

Okay this below is 'normal' with a 3050 watt cap

total of 6100 watts

which would be too much for the  cooler if it can do 6000 advertised number.

oh did not know that.

thanks for info.

We used a combination of BTC mining and New Jersey solar power incentives to build a 45kwatt solar array a 115kwatt solar array and a 280kwatt solar arrary.


These small commercial projects are scalable to 2megawatts in NJ. You need a proper site and an investor willing to create the array mean we can have a lot more setups done like this.

Hey guys new fud

Fungal infections are becoming more common. Why isn't there a vaccine?

from below


https://www.yahoo.com/lifestyle/fungal-infections-becoming-more-common-120000710.html

that is not uncertain that is a lie.


1) crypto/btc is not going to be worldwide banned tomorrow.

but if you said that

2) all the governments of the world have the ability to declare crypto/btc illegal over the next 2 years

that is uncertain.

so 1 is not okay to say
2 is okay to say.


part of life is constant uncertain shit happens day after day.

it is okay to talk about it.


The other day I read the earths core stopped spinning then reversed its spin.


https://www.cnn.com/2023/01/25/world/earth-core-turning-scli-scn-intl/index.html


A) I never heard about this
B) seems interesting
C) I have zero idea if it is a bad thing for us as humans.

D) if I say it means we humans will all die as this means the second coming of christ and the end of times.  I would be lying as I have zero idea if that is true.

E) if I say it scares me and I hope that it won't speed up Greenland from melting So I am selling my beach house moving to the mountains.

I am spreading an uncertain set of  issues that I have about the earths core.

F) the reality for me Is I don't care as either way I will be dead in 50 years or less (I am 66 right now)

It is a fine line between lying and uncertain shit and how you say it.

I will likely set them to 2800 watts as the cooler is supposed to do 6000 watts max.

update. I set to normal speed and used the whatsminer's tool to lower watts to 3100 or less.  results below:


So I save 300 watts and drop from 96.0 to 93.8.

2 at this setting would likely be to hot for the cooler.


but I do know that setting on low does 88.1 and 2850 watts which would be good for the cooler as 2x2850 = 5700 which is under the coolers 6000 watt spec.

Yeah the problem is governments truly do not want an unstoppable transfer of wealth.

Matter of time before they were reached.

I am a trezor guy.

does this wallet provide proper seed recovery?

24/7/365 power use means you have to derate the power by a factor of .8

this is to prevent wires from melting.

So if he has 2000 kwatts or 2 megawatts in transformer rating x 80% gives the  proper safety factor of 1600 kwatts or 1.6 mw


so 1600/3 = 533 s19 units doing 3 kwatts each.


As for proper staffing a lot depends on the op and his or her knowledge of mining.

500 units  can be done on 2 routers  each with 1 pc and 250 miners.  this means 2 internet lines.  which is a decent idea for redundancy.

500 x 100 = 50ph hash or

50000th hash

50000 x .071= 3550 usd a day.

as for fear of viabtc and referral misuse,  here is my viabtc referral

https://www.viabtc.com/signup?refer=680499

simply join viabtc with that referral and I get a piece of  the fees viabtc is collecting.  you the miner do not pay extra.

so obviously this means by working with 1 outsider you have a record of your miners since the outsider gets the hash rate number and th referral fee.

so at no cost to you you get a free check on your hashrate by some one you trust.

it does not have to be my referral .

So if he opens an account with 250 miners. doing 25ph from 1 router he can glance at his viabtc stats on his account and he can check with the person that has his referral to see if it matches.

To be honest. this gear needs very little hands on work.

depending on filters and your dirty air or clean air. Maybe a 60 to 120 day clean out schedule .

500 machines at 10 minutes a machine is 5000 minutes of work. that is 80-90 hours every 2-4 months.

10 minutes to check that gear is running say 4 times a day. is 40 minutes a day. 1200 minutes = 20 hours

then trouble shooting the bad gear. maybe 1 day a month = 8

so 100 hours a month of work is about right.

Of course access to a good repair guy = needed

fuzzy beat me to it as I wanted to address the fraud issue.

and as if on cue the gear comes in and price drops with difficulty getting a bit worse.

we were 41 block down and we are now 30 blocks down



we were at block 1488 and now are at block 1740

we were down 40 blocks and are now down 30 blocks

so 1740-1488 = 252 made we gained  10 blocks so

252/242 = 1.0413

a 4.1% gain for about the last 2 days

I often wonder how much is off line that could come back if we jump to 50k.

for instance If it is cold and I fire everything we have I could go from 1.7 ph to 1.9ph

that 200 th is shit gear with bad power stats.  I have been pulling it offline and putting in s19 and m30s+

I have some m10's an Avalon a1047 some s9's.  So I wonder just how many people have older shitty gear on the sidelines along with people have new s19's idle


So diff is - 1.76% and price is 21.7k

We could go to -1% or maybe -3% who knows.

yes you can take a loan to invest in anything you want.

proper question is should you thank a loan.

the correct answer to that is each and every person has different circumstances and knowledge.

for some the answer is yes for some the answer is no for some the answer is maybe.

I took a 12000 cc loan in sept of 2022

I took a 3200 cc loan in dec of 2023.

the 12000 loan is paid . I made 740 usd on the loan instantly and now get 3 usd a day .

But most no one in the world has the circumstances I had to do that loan.

the 3200 loan is down to 1700.

I made 264 instantly and it earns me 6 a day. I have until feb 2024 to pay this loan.

both loans are interest free.

The investment was in btc mining gear.

but for this to work you need really good credit.

you need a cc offer for a new card
say it give 1 year to 15 months no interest.
and it gives a bonus of 200 or maybe 500 bucks with a large buy.

also you can not do it often maybe one ot two loans a year.

2mw x .8 = 1.6 megawatts

so 3k watts x 500 = 1.5megawatts


so you may be able to run 500-550 not 650

the s19 exhausts 500+ cfm. so 500 x 500 = 250,000 cfm


this means you need

30 of these

https://kn5.ada.myftpupload.com/36sf8n370-shutter-fan/


along with a way to let air in.

All rough numbers but kind of what you may need for what you want.

https://www.zoro.com/hessaire-36-shutter-fan-8860-cfm-36sf8n370/i/G003071042/?


30 x 700 = 21000 for exhaust

metal filters for intake help


https://www.cartergoods.com

 gold merv 8 washable

you will need a lot of them for intake. maybe 60 of them.

so 60 x 60 = 3600

duct work will be needed.

a lot of cabling is needed.

a lot of shelf maybe 15 sets of them.

they need to carry weight well.


https://www.webstaurantstore.com/regency-18-x-60-x-80-nsf-chrome-mobile-wire-shelving-starter-kit-with-5-shelves/460C1860KM75.html

these carry 600 pounds that is 20 pieces of gear per shelf so 25- 30 sets

30 x 220 = 6600


so

  6600 = shelf
  3600 = filter
21000 = fan

power cables are complex a lot of ways to set gear up with cables  but  500 of them  will cost
pdus will cost

I run 60-100 units of gear we have spent a lot setting up a warehouse .

you may want to go the container route.

gear is here.

I will dry air test these in my garage.

First one is powered up on normal. 96 th as you can see the middle board is a bit low.

but not running for a long time. I will give it a 3 hour run on normal then test low and high speeds.



My thanks to mikeywith for helping me to get this
