Antminer farm now operational!

[MrJaekin]

I see you are pushing the hot air out the window.. where is the cool inlet air coming from? If this is an inclosed garage, wouldn’t this cause negative air pressure?  Reason I ask is I’m thinking about doing this in my garage since I can’t find a good hosting company for my S9s. Thanks!

It would be too hot to run in my garage, it's in a bedroom. The cool air is being generated via a portable AC, with the intake hose outside of the room pulling in air from the rest of the house.

If you're going to run in your garage, just make sure it's not too hot and that you have good airflow (intake & exhaust).

Oh, haha! I thought from the second picture it was a garage door. My mistake. 😀 Thanks!

Hello GM Poison...

How did you figure out your ventilation part?
What calculation did you use for intake and exhaust?
What fans are you using?

Please share your experiences and lessons learned. Thanks.

nice one  but how much did it cost you overall and what do you expect to collect from it at daily basis.
would like to see some stats about the operation.

Curious about startup costs as well, aside form miners.

Did everything run well from now ? any problems?

@mrayazgul - I'm running them via Nicehash, you can figure out how much they make by using the calculator on their website. Lets just say, the electricity bill is not an issue.
@BelieveInBitcoin - Worrying about not hitting ROI is not something you have to worry about with these miners.
@BitcoinIntern - Lots of planning, and I don't have the intake/exhaust down to the very last CFM. Just make sure you have good airflow and if you can, do a hot/cold isle like I did to contain and exhaust the heat.
@jrrigs - Changes every day, but yeah, a very good ROI time.
@cupic - None of them are overclocked. I don't want them running hot, I don't want to consume the extra electricity, and I want to get top dollar for them when I go to resell them. They're well taken care of.
@sabrikks - You can calculate all of the numbers using the Nicehash calculator on their site. As far as what it cost me, I got each machine for $1650, electrical install was $4000, and misc. equipment wasn't much.
@hotmetaldobermans - The largest cost - obviously - are the miners. Next to that there was the electrical install and misc. equipment which wasn't anywhere near what the miners themselves cost.
@FrenchinHK - No problems thus far luckily. I don't have them overclocked, they're running at good temps, all is good and I'm taking good care of them to keep their resale value up.

How many in total can you run on those 30A 240Vs?

How many in total can you run on those 30A 240Vs?

They each consume 800w, and 30A @ 240V is 7200w, so the math would say 7 or 8 safely.

Nice Setup!
With 18 L3s you need around 4,000 cfm (18*220cfm) on your "cool room" how much air is your portable AC providing? Same on the "hot room" Be careful with positive and negative pressures.

He actually has three (3) 30A 240V circuits. That's 21,600W. That's 18 maximum if I am not mistaken.

I think you should replace those tarpaulin with more solid thing like plywood.
Also tarpaulin seem to be more easier to be burned

get rid of that tp link switch, its crap and you will eventually have connection problems. any miner with that kind of setup should know any type of networking hardware with link in the name is crap and eventually has link problems down the road, get something that's better

The TP-Link products I've been using have been working just fine. If and when it ever fails, it will be replaced.

This is a great setup. However, I'm quite concerned about the costs that you will be making for paying your electricity bills.

Don't be, it only takes a couple of days to pay off the entire electric bill for the month, then it's all profit

[GMPoison]

I might be interested in selling the entire setup (miners, power supplies, cables, switches, etc, everything needed to start mining included) if the price is right. PM if you're the slightest bit interested.

What happened to all the pictures on this thread? I was trying to figure the PDU's used here and can't seem to find the pictures. If anyone remembers what PDU's were used in this project? I remember the industrial socket ones but don't know the model. Thanks.

l3s still make near 500 a month why would u sell
