Garage / Residential Data Center Mining Cave Planning - Garage Grotto Part 1 :D

[VoskCoin]

Hi guys I decided to make my own thread as I have a lot of questions . .

First I'm looking to setup an in home mining cave, I only have funds for ~5 rigs currently but I have goals of filling rigs to reach my electric capacity (200 amp box)

http://imgur.com/a/kUQqI

Please review my pictures, garage is semi underground, area is all cleared out now for mining, however a car will also be stored in the garage, it is a 1 car garage but honestly about the size of a 2 car garage.

You can see the panel in the back left, I am planning to upgrade the electric

Question #1 Can you please explain the rough max electric I can run for this system and how I should do it?

Question #2 How can I manage heat in this setup, there is only one door to the exterior which mimics a front door and then the garage door, the area closest to the concept mining area which is that indent in the garage however it does not have to be there, just seems to make most sense?

Question #3 Racks etc, my setup will be mostly GPU rigs, whats the best rack setup I can use as far as being useful, cooling, and looking decent

I have more questions but these are my main concerns at the moment, would love all input on how to successfully create this so that the setup is very efficient.

Looking it over.

Okay you have an interior door  where does it lead to?

My idea is build a diy barn door inside the garage mount one fan like this


http://www.homedepot.com/p/Ventamatic-Cool-Attic-1650-CFM-Energy-Efficient-Power-Gable-Mount-Attic-Vent-CX2500UPS/202913826

so if you open the interior garage door  you see the diy sliding barn door  and there would be a fan like above pulling air into the garage.  obvious you need screens

the fan pull air in could be this one but must be at the bottom of the  interior entrance.

http://www.homedepot.com/p/Ventamatic-20-in-High-Velocity-Floor-Fan-HVFF-20UPS/202795625

this will bring in cool air from the house.

you will need an exhaust fan

which means put a window in the garage to exhaust air out

Interior door leads to the basement hallway connected to my bedroom one way and stairs the other

Also side note, I want to consolidate this into one thread and philipma I know we've talked briefly about this

I have a rig consisting of this

5x Sapphire Radeon VAPOR-X R9 280X 3GB GDDR5 w/ boost pcie /// ZCASH 1300h/s not overclocked

Intel Core I3-4160 Processor 3.60 GHz, 2-Core LGA1150 Socket, Hyper-Threading

ASRock H81 Pro BTC Mining LGA1150 HDMI SATA 6Gb/s USB 3.0 ATX Board

2x Seasonic X-850(SS-850KM3 Active PFC F3) 850W 80 Plus Gold ATX12V/EPS12V Power Supply

2x Crucial Ballistix Sport 4GB Single DDR3 1600 MT/s (PC3-12800) CL9 @1.5V UDIMM 240-Pin Memory Module

Kingston Digital 120GB SSDNow V300 SATA 3 2.5 (7mm height) Solid State Drive (SV300S37A/120G)

Power Supply Reset Switch Motherboard Cable

5x PCI-E Express 1X to 16X Riser Adapter USB 60cm Cable w/ SATA or Molex Powered

KADA 6.1 GPU Mining Rig Open Air Frame Case Aluminium Chassis

Dual triple power supply adapter connector Relay Adapter link multiple add2PSU

I have a spare powered riser, no spare cards, and can add another card onto the PSU w/ 2 cards --- so really I am just trying to figure out how I can add a 6th card to this rig (running windows 10 w/ trixx) I do not want to sell the cards I think I'd rather just add 1 more, with that in mind should I hunt down another 280x? What about a nice nvidia to continue zcash? or Simply an rx470 4gb and turn this into an ETH rig

#1. You said you had a 200 amp panel, is that a panel dedicate for the rigs, or your whole house? If it's a dedicated panel for rigs, then its simply 200*240*0.8 = 38,400 watts, or half that for 120v.

#2. You are gunna need an intake/outtake. Garage door is the obvious intake, using louvers. There are many examples around the forums. Definitely check out @yun9999's thread. I would turn the door to the outside (i don't see it in the pictures, but I believe you said one exists) into an exhaust. This would be easiest if it is a door you never have to use. You could mount a large fan in the top half of the doorway. What you'll need for fan size will be determined by how many rigs you have, and the ambient temp. Do you live in a hot area or no? That indented area may be fine for the time being. If you scaled enough I may worry that it is not close enough to the exhaust (although, again, i don't see the door, so i'm not sure). With 5 rigs i'm sure its fine.

3. The best racks for looks are definitely 42U server cabinets, but you'll pay up for them for sure. Metal wire shelving units that many miners use are much more cost effective, but are ugly and cable management can be difficult. I've also been told the server cabinets are better for cooling, I can't say from experience, but it would make sense to me.

Phil, feel free to correct me on anything

Interior door leads to the basement hallway connected to my bedroom one way and stairs the other

I put info above.  I think you can feed cooler air in via that door.

but you need a window for an exhaust vet in the garage.

cool air in basement >>> garage door >>>>> miners >>>> exhaust vent

So here is my base layout of the garage, if that is the case I would have to run miners right next to that door in order for that airflow concept to be efficient? What do you think based off that floor plan?

Phil, feel free to correct me on anything  

its for the whole house, so I'm thinking I could cut it in half to dedicate to mining?

Thanks for the input please review this http://imgur.com/Nij8gSv

I live in a relatively hot and relatively humid area (virginia) and I pay 14c kwh so I need the setup to be efficient as my electric is not cheap

https://www.newegg.com/Product/Product.aspx?Item=N82E16816228172&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Server+Racks%2FCabinets-_-N82E16816228172&gclid=Cj0KEQjwrsDIBRDX3JCunOrr_YYBEiQAifH1Fl9raOwfOqCvS1kjQYIZ308iBLQgzYc9LdZVj1TX0i0aArSs8P8HAQ&gclsrc=aw.ds I would never profit a dime with racks this expensive! lol I'll definitely opt for the metal wire shelves xD

[Sequoia93]

Yeah if you're lucky you can find the server racks used for cheap, but I still opt for wire shelves. Home Depot and Wal-Mart sell similar brands for cheap with a 600lb rating per shelf. You could fit ten rigs on this: http://www.homedepot.com/p/HDX-48-in-W-x-72-in-H-x-18-in-D-Decorative-Wire-Chrome-Finish-Commercial-Shelving-Unit-6T60184872C/100655787

For the electric, I would opt to add a 100amp (or two 50amp) circuits into your box at 240v. Or maybe swap some 120v circuits for 240v if the box does not have the room. It will be pretty cheap to have done since your box is in the garage and the electrician won't have to run wires a long distance/through walls. The 240v circuit will help with efficiency/your high-ish electric rate. I'd talk to @Finksy about some platinum server PSUs if you plan to have 5+rigs. Again, it'll help cut the hurt of the $0.14 electric.

As for cooling, I'd personally put the rigs right in front of the door going to the outside. Exhaust fan on the door, you might be able to put a louver in place of the window on the door. Then I'd put louvers along the bottom of the garage door for intakes. Just make sure you have enough to match the power of your exhaust fan. If you do get up to ten rigs, I'd get a fan ~3,000CFM, but that's a serious shot in the dark. idk nvidia rigs, and idk virginia.

[Marvell1]

start with 200 amp or you will regret it in the long run

[VoskCoin]

start with 200 amp or you will regret it in the long run

I can only run half at most I'd imagine with my house box being 200?

[gwestcot]

I would definitely have a dedicated panel installed just for your mining. You will more than likely want to expand and you want to have the circuits and the amperage to do it.

[navydude]

I just did a quick read through the posts and could have missed something. I would use exhaust fans as recommended but I would separate the mining room from the house. Do not draw the air from inside the house, pull the air from outside. Arrange the rigs so that the air pulls directly across the rigs. You want a exhaust fan big enough to exchange the air in the room several times per minute. Even if the temps are 100f outside, when you are pulling that air across your 65c to 70c card temps they will stay cool. 70c is 158f so the outside air will cool if you have proper air flow. 3000cfm is a good starting point. I am moving my rigs out to a 12x26 storage unit that I had set in the back yard. I am going to go with 7,500 to 10,000 cfm because i want the air to be exchanged many times to keep the heat minimized. There is no reason to put in a 200 amp panel right now unless you have the money and know you will add several more rigs in the future. Its gonna cost so be prepared.

I have 9 rigs on my main 200 amp panel. I dedicated 4 double pole 240v breakers just for mining. You dont want the breaker to be loaded more than 80 percent. If you run your rigs on 240v you can double the amperage of a 120v circuit and run more efficiently. At 240v you could run approx 20+ rigs on a 200 amp panel. The wire racks work perfectly. It gives very good air flow for the cards. Unless you are rolling in the money there is no reason to buy those expensive sever racks. 75 bucks will allow you to set up 6 to 8 rigs on a nice wire rack. Thats my 2 cents.


I was actually thinking of this. Haven't decided on fan size yet.

[Sequoia93]

OP, if you take a picture of the inside of your panel, I can check how much room it has to add circuits. If it is full, you may need to add a second box, but it really is not that expensive.

this is my idea for him he needs to cut 1 vent in back corner of his garage.
he needs a strong exhaust fan so air is pulled from cooler home.  
this setup keeps gear away from car and lets a car be parked.
only one cut in garage for vent.
and cooler air flows into garage from basement
if ac bill goes too high  he can close basement door  and open garage door 2 inches use this

from garage door to vent  inside door shut

http://imgur.com/a/kUQqI Please review the album as I have uploaded 4 more pictures that show the layout a bit better and also show the panel

Apologize for all of the junk everywhere, still moving myself in and have some of my familys stuff stored here as well for the next week

What could I potentially cut down  to maximize my potential energy, looks like I could squeeze ~25 rigs onto 100 amps?

Granted I don't have 25 rigs yet but that is most certainly the goal!

I'm really willing to go to any extent to make this happen, but budget is certainly a concern! http://imgur.com/a/kUQqI please review the updated pics for a little bit of a better idea, I will also upload a picture of what is in the area behind the extended portion of the garage, it is essentially a small maybe 6x6 utility room with my water heater / ducts

I appreciate your concern for the car xD as I am a car guy and will have to park my racecar in there however my focus is on the mining rigs as the car seems to spend a lot more money than it makes lol

I am willing to put the mining gear anywhere along the basement door side / the "cubby" area / basically anywhere but the footprint of a vehicle in front of the garage door + the wall on that side is pure concrete

Does that number seem accurate? ~25 rigs max based on my power capabilities? so we should be building cooling based on that? Also what is "too hot" for a miner to run are cards running at 80c+ "too hot" what exactly is an ideal temp, okay temp, bad temp, and critical temp?

How would I effectively move the air? I could understand cutting a portion out to install an intake fan and blowing the air across the rigs if they were stationed next to the basement door
review pics below
http://imgur.com/a/kUQqI
I'm worried even that space left there next to the door may not be big enough? I could figure out a way to replace the door with a large fan . . I have two entry doors and could simply enter exit through the true large garage door or the other entrance door. This might actually be one of the better routes as there is already that large hole there simply filled with a door? What are everyones thoughts?

My goal is to make an efficient and cost effective setup to handle as many rigs as I can. Once I have acquired funds/ setup max rigs (currently only have ~5 rigs worth / most are parts en route etc) I'll have 2 GPU rigs running by the end of the week and the goal is 10 GPU rigs by the end of july / 5 by the end of the month)

Also for example one of my mining rigs is the mining cave cheetah https://miningcave.com/product/mc-cheetah-sk1/ it's running on standard 120v socket currently, with these atx psu (this uses rosewill 1200w (photon/gold)) I simply plug into 220v correct? How do I ensure units are setup to handle increased power as to never damage a unit

Certainly not rolling in money and I'm thinking the metal wire shelves will be perfect for my setup goals and above all ..  budget!

I would definitely have a dedicated panel installed just for your mining. You will more than likely want to expand and you want to have the circuits and the amperage to do it.

If my main panel is 200 amp is there any chance my system could potentially have the capacity for a 300 amp panel and they simply put a 200 amp in or do they always put the max amp box per your electric setup

I won't comment on the air flow thing because I haven't looked at that too much. I wouldn't buy rigs from anyone since they charge such a premium and they aren't very hard to setup. I use EVGA PSU so I don't know about Rosewill but EVGA will take any voltage from 100V-240V. This would mean that you would be just fine as long as your PSU is similar to the ones I use. It will usually have the allowable voltage on the outside of the PSU or in the literature that comes with it. I also doubt that you can get 25 rigs in your garage based on the availability on your panel if you use the standard 120V.

This might actually be one of the better routes as there is already that large hole there simply filled with a door? What are everyones thoughts?

My goal is to make an efficient and cost effective setup to handle as many rigs as I can. Once I have acquired funds/ setup max rigs (currently only have ~5 rigs worth / most are parts en route etc) I'll have 2 GPU rigs running by the end of the week and the goal is 10 GPU rigs by the end of july / 5 by the end of the month)

Also for example one of my mining rigs is the mining cave cheetah https://miningcave.com/product/mc-cheetah-sk1/ it's running on standard 120v socket currently, with these atx psu (this uses rosewill 1200w (photon/gold)) I simply plug into 220v correct? How do I ensure units are setup to handle increased power as to never damage a unit

Certainly not rolling in money and I'm thinking the metal wire shelves will be perfect for my setup goals and above all ..  budget!

I won't comment on the air flow thing because I haven't looked at that too much. I wouldn't buy rigs from anyone since they charge such a premium and they aren't very hard to setup. I use EVGA PSU so I don't know about Rosewill but EVGA will take any voltage from 100V-240V. This would mean that you would be just fine as long as your PSU is similar to the ones I use. It will usually have the allowable voltage on the outside of the PSU or in the literature that comes with it. I also doubt that you can get 25 rigs in your garage based on the availability on your panel if you use the standard 120V. 

1000 watts @ 220v = ~5 amps so assuming I can fine tune rigs down a bit, and a few smaller rigs not drawing quite as much power, along with fans, I could shoot for 20 rigs?

Also sidenote for everyone participating in this thread I think I'm going to make a little plaque and hang it in the mining center to dedicate individually to each member who's helped in this thread xD


I have several electricians coming over the next week, the first being tomorrow morning actually so I can have his opinion as well as far as what he would charge to do this work. I've done a lot of work including building a freaking large tiny home lol but I did everything except for the electric & plumbing there

[Sequoia93]

Your panel appears to have plenty of room in it. Those blank gray spaces without switches can handle additional circuits, so you would not need to add another entire panel. The electricians will tell you exactly what they can put in, but I see room for at least 100amps if not more. I think you could fit 4 240v 50A circuits if you move one smaller circuit to the opposite side of the box. Then they can install however many outlets you need. You could do something like 4 50A ciruits, each with its own outlet, and plug a 50A PDU into each outlet. Or twice the outlets/PDUs with PDUs rated at 30A. But again, talk it out with the electricians, I am not qualified for such work so don't follow my advice without asking a real professional!

I also use EVGA PSUs which you can just plug into a 240v PDU. Some PSUs have 120/240v switches on the back (maybe only older models?). But your PSU should say on it somewhere something like "100v - 240v 50hz - 60hz". If it simply says "100v - 120v" you are out of luck. With that many rigs I would highly recommend getting some server PSUs to supply the bulk of the power anyways. Finksy sells entire packages that will make your life way easier. If he is out, pm me for additional sources.

Phil's diagram for airflow would definitely be more efficient than what I suggested. Here is a diagram of my suggestion: http://imgur.com/a/AQW9x

Again, its not ideal in terms of airflow, but it may be more feasible than putting a hole in the back of the garage, and sucking air from the house. Not to mention it will be LOUD with the door to the inside of the house open. Also note that you have to have enough louvers to match the exaust fan, too few and it will be extra loud and wear on the fan motor.

I do not know how much electricity your nvidia rigs need, but assuming you have everything running off 240v circuits and the full 200amps, then you can pull up to 240*200*0.8 = 38,400watts... so divide that by the peak power consumption of one of your rigs measured with a proper wall meter. While that could easily be 30+ rigs, you may run out of space/cooling capacity before electric.

I garage mine  I open a back door put in a box fan. in the summer not the winter

I leave the interior door open  almost every day of the year.


In the summer with ac running  3 kwatts  is my max

In the winter when it is 30 f  6 kwatts  is my max.


mind you I can feed  48 amps at 240   which is 11.5 kwatts    but house gets really freaking hot and wife gets very angry.

At the moment

 I have:

 8  1080 ti's
 1  1080
 2  1070
 1  1060

5 rx 480's

8500h of zec pull 3kwatts.

I will need to drop to

1.5 kwatts for the summer.

Should I be running 240v over 220v? Can someone elaborate please

What outlet setup do I need this part I do not understand,

I'll be throwing the rigs on racks, how can I run power to all of them and maximize my circuits

Can someone suggest how to accommodate all of these plugs effectively?

This is more minor but running the Ethernet cables - best clean option?

[Sequoia93]

As for 240 vs 220 I am not sure, is that european vs american standard?

Either way they are more or less the same, a PSU will be rated like "100v - 240v" and can be plugged into anything in that range.
Although I'll say again, DISCLAIMER, I am no electrician, please verify with a professional.

As for power, you'll want to pick up some 240v PDUs. They are very reasonably priced when bought used.

Ehternet cables can be tied along legs of the rack, and all plugged in to an ethernet switch such as this: https://www.amazon.com/NETGEAR-ProSAFE-Ethernet-Rackmount-JFS524-200NAS/dp/B00DCUKCVW/ref=sr_1_2?s=pc&ie=UTF8&qid=1494430119&sr=1-2&keywords=ethernet+switch&refinements=p_n_feature_keywords_two_browse-bin%3A7306164011

Also after talking to these guys I think I'll have to change my plan I'm just going to screw the house up, more complicated, more expensive, etc when I could just drop a shed on my property and then have free reign to do everything that I want to do on there

So.  . what size shed do i need here my plot I can work with is 15x20

I'm thinking 12x16 would would be plenty, 14x18 maybe max?

[VoskCoin]

So revised plan . . .

I have ~13 ft width and 20 ft length asphalt patch

Drop 12x12 or so shed on said patch

Run fans <---exhaust [SHED] <--- intake / electric run, secure facility and done? 12x12 should give me ample room to run enough rigs to max out my power -- agreed? Thoughts / input?

Can anyone give me links to exact fans that would work for this setup, 3000 CFM?

Thank you for everyone helping here

Shed is a great idea. With 3000cfm fan pulling from inside your house your home A/C would never keep up anyway and would run constantly, taking all your mining rewards. The size(mining are) isnt that important...getting the heat out quickly is. I hope to have my shed delivered in the next two weeks. I still have to get underground power over there but shouldnt be much of an issue. Im going with a 36" 5000cfm fan. I will be getting a 12x26 shed and dividing it off only to use a smaller portion for my mining room( approx 10x12 area). The rest will be storage. If you havent got yours situated by then maybe i will have more advice at that time. I think the shed is the proper way to go.

[WarrEagle]

5 Rigs or are you going to grow. You can run 5 rigs on a 50 Amp 230V circuit easily with room for about 4 more. You have plenty of open slots for expansion. I would definitely recommend a PDU or 2 to handle the PSU connections from the rigs and run them at 230/240V since the PSU's are more efficient. It's only like 2-3% but worth it.

You are running older cards and will want to exhaust the heat generated by those 280X to the outside. Phil has a good idea, I did something different and bought 2 - 30 inch barrel fans and opened the garage side door and stapled a screen over the frame. Built a tarp canopy out of PVC pipe and a tarp to keep out the rain. Placed the fans on a wire shelf and had them facing so that they pulled air across the rigs in front of them. Had to keep my garage door open about 4 inches to let fresh outside ambient air in. In August in Florida my cards all stayed under 75 degrees Celsius.

I ran 5 rigs for several months last summer. I only have 100 amp service, and was tripping breakers a lot, especially since we have a Volt with a level 2 charger. I had to explain to my wife not to plug in her car till after we finished cooking dinner. Stove + Volt + A/C + Hot water tank + Rigs overloaded my mains.

Good luck with the build and post some pics when its running!

How large was your garage and how many cards were you running? Those are some pretty good results in FL!

[WarrEagle]

I ran 30 cards total, 5 rigs, 6 cards each. All 380's 600 MH/s mining ETH. I was finding a 1.5 blocks a day when I first started, then a block a day as more people joined the circus.

Power bill was $850 to $900

Oh, now I look stupid. The PDUMV30HV. I chose this over one of the smaller cheaper options because my setup specifically needed two separate monitored circuits, one for the top half and one for the bottom half of my rack. For a small room as long as you're going with a limited number of power supplies one of the smaller PDUs should work just fine.

Okay so my question to you and everyone else is specifically on these fans,

I'm going to get a dormer style shed unless anyone recommends against that?

With the fans, should I just mount a massive fan blowing up and out / attic style fan like suggested?

Sorry for all the questions, trying to make sure I knock this out once & right.

Also I'm thinking two fans would make more sense because then if one goes down I can still limp along, also while my setup is still growing I could simply use one fan?

Definitely keep me posted, even just update your journey in this thread if you'd like!

Why did you choose a 5000cfm fan?

for 20-30 rigs with 6x cards each in a 12x12 how much fan am I going to need?

What's the best setup for the fan? blow through intake on right exhaust on left side, or intake vents on both left and right with 2 big attic exhaust fans in the middle? Just want to build the most efficient setup possible you know?

[VoskCoin]

It's not the cleanest and I don't have any pictures of the PDU up close, and this garage is 30 minutes away so I can't get any of it right this second. But you can see it hanging on the side of the rack to the left and the L6-30P plug on the wall behind the rack. Top rack is mine, 16x 1070s. Bottom half is a friends 12x 1070s and 4x 470s. Running in a 3rd friends garage, which is why we needed a metered PDU, split to monitor my half/friends half. (not pictured, 3rd friends small setup of 470s).

I still have to get underground power over there but shouldnt be much of an issue. Im going with a 36" 5000cfm fan. I will be getting a 12x26 shed and dividing it off only to use a smaller portion for my mining room( approx 10x12 area). The rest will be storage. If you havent got yours situated by then maybe i will have more advice at that time. I think the shed is the proper way to go.

Definitely keep me posted, even just update your journey in this thread if you'd like!

Why did you choose a 5000cfm fan?

for 20-30 rigs with 6x cards each in a 12x12 how much fan am I going to need?

What's the best setup for the fan? blow through intake on right exhaust on left side, or intake vents on both left and right with 2 big attic exhaust fans in the middle? Just want to build the most efficient setup possible you know?

You will have to determine the total cubic feet of the space your trying to cool. So if your space is 10x12x8 = 960 cubic feet
If you get a 3000 CFM (cubic feet per minute) fan, it will take about 20 sec to displace that space with "new air".
You will also need to consider intake and exhaust, make sure you have adequate airflow.

You ever have a 18" box fan and cover the back of it with something? It kills the air flow. Samething could happen with your setup.

[eth4lyfe]

Which one exactly? ^



Guys what fans should I be using? Simply slap a large (but how large?) intake fan on the right side then blow through and a large (is 3000 CFM the right size?) exhaust fan on the left. Is it this simple?

Oh, now I look stupid. The PDUMV30HV. I chose this over one of the smaller cheaper options because my setup specifically needed two separate monitored circuits, one for the top half and one for the bottom half of my rack. For a small room as long as you're going with a limited number of power supplies one of the smaller PDUs should work just fine.

Do you have an photos of your build? Definitely a visual man xD

It's not the cleanest and I don't have any pictures of the PDU up close, and this garage is 30 minutes away so I can't get any of it right this second. But you can see it hanging on the side of the rack to the left and the L6-30P plug on the wall behind the rack. Top rack is mine, 16x 1070s. Bottom half is a friends 12x 1070s and 4x 470s. Running in a 3rd friends garage, which is why we needed a metered PDU, split to monitor my half/friends half. (not pictured, 3rd friends small setup of 470s).

Have you noticed an improvement in cooling by hanging them vertically like that? This is my setup, yours looks cleaner though https://i.redd.it/kl8ixkuks0uy.jpg

You should trim the ends of your zip ties! lol

I haven't really noticed an improvement no. The room still heats up like crazy regardless of orienation. For blower fans it helps keep the heat in an upward direction but there comes a point where it just doesn't matter.

If I had a dollar for every time someone told me to trim those things I wouldn't need to be mining at all.

Planning on 12x12

Ultimately what's the best plan for cooling two 1500-2000 cfm fans mounted on one side? on the ceiling? one on side one on the ceiling? Also how much sq ft in vent would I need to keep proper airflow? Sorry for all the questions this is just out of my realm!

How much does it cost to run these large exhaust fans?  What's their typical draw?

I'm a hobby miner with a hot room, so I'm curious what added cost these things have, compared to running a box fan or playing with higher AC use in my house.

If I remember right at 10c kWh it was less then $10 bucks a month.  Did not matter
in my case I had to move some air. Again, this was no thermostat, just 24/7 one month.

I'm running one of these in my garage.  It's loud, and pulls ~ 500W by itself, according to the label on it, but it moves the air through the exhaust hose very quickly.  I also have one of these pushing air over the equipment, with everything enclosed.  This allows the ~30 cu ft of air that the miners occupy to be completely refreshed every few seconds.  It's way cheaper to move a lot of air than it is to cool the air, so AC is a total waste of money and energy for this kind of thing.

I also forgot to mention I have hanging on bracket equiv pusher fans on the other side of the basement to push air thru to the shutter fan.

This one is 120 watts and 120 volts 18" hanging bracket fan

raise my hand up and there is a wind How I get the heat out

temp wise..well ....no choice really ...have to move AIR temp does not matter much ..I suppose 8 degree F maybe

Had equiv of 5 Titans running in the basement last summer. IT mostly stayed below 80F ...... a few days it hit 85F ..I think 1 day I shut the miners off due to heat

but me...I need the air flow .....again I suppose 16" is better if you don't care about noise

also I do not have thermostat on shutter fan because the louver's when fan off doesn't shut sometimes...i could have maybe put a weight ot something tricky
to get them to do so...but wtf it is summer ....and again at less the 10 bucks (1 fan) 24/7 I just let them run that's per fan per month...i had with 1 shutter fan
2 pusher fans....a rare day when all 3 were full out.but when I had to do so ...was nice they were all available

the pusher fans I used (bracket in front of other side of basement window hanging) pics are on my above link if you need such

anyway it all works well...only 2 titans down there now...soon all will be at data hall and the 75w 300mh baikal cube will hardly need the airflow

Again all this stuff is at Menard's hardware store....

www.menards.com


anyway good luck .it is all about moving air

[TeamGreen]

I have 9 rigs (6x 1070s ea.) going now in an apartment with a 200A panel.  Dealing with the heat was definitely a process.  I upgraded the fans you see in the video to 3x 6200CFM (they are 3-speed and we have only needed 4000 CFM for now up to 88 degrees ambient outside temp).  I have two pushing air out the big window which creates negative pressure and pulls in a ton of air from the side window.  The third one is on standby for now and interestingly the temp actually goes up if I set the 3rd one up to pull air in the side window.  Temp inside usually stays within 7 degrees of ambient outside temp with 2x fans exhausting heat out the big window at 4000CFM per fan.

I'm intrigued by that blower/hose combo. How well does it work if you have a wider area of hot air from multiple rigs? Does the hose constrict the air movement? I like the idea of something that can be moved around if it needs to, but is more powerful and longer lasting then a box fan.

Is there any real benefit to the PDU? with the setup I'm looking at making I don't see the purpose of a PDU as I can add more outlets at a lower expense than PDU, I don't have them yet but I'll need to have them installed this month, so i'm open to suggestions / best ideas from you all

[Billz007]

A PDU will allow you to plug multiple rigs into an outlet.  If you have an L6-30 type outlet, look at the APC AP9571.  These can be had for a great price on eBay.  I ordered 2 of them from eBay a couple weeks ago.

Using ATX PSU, do I need to upgrade the standard 120v style power cable it comes with if I'm using it on a PDU

what's the ideal breaker size / rigs to run on it / best tool to determine exact power draw?

Electric has been a frustrating component of all this 

[Billz007]

You'll need C13 to C14 cables.  I have the 14AWG (gauge) ones.  Business rackmount servers come with these as well as the standard cables.  My dad's business had a bunch of extra ones.

I was going through the same troubles as you trying to figure out the proper electrical setup.

This link really helped me figure out what I needed.

https://bitcointalk.org/index.php?topic=74740.10

[Billz007]

I'm going to have two 30-amp breakers run to two 30-amp L6-30 outlets.  As far as tools to measure usage, I'm not sure.  But the amps a rig takes at 120v is cut in half when put on 240v.  I think I'll just use a killawatt to measure a rigs amp draw at 120v and then plug the rig into the 240v.  That's the only solution I have right now to estimate amp draw on 240v.

[stoon]

Be cautious but my kill-a-watt tools worked when i used them for 240v as well as 120v. Most of them are made the same just a different plug for different parts of the world.

grab some metered PDU's, nuff said

[gwestcot]

A PDU can be used also to step down in voltage. If you are smart, IMHO, you would setup a 480V 3 phase service with your electricity provider. In my local are you can set up as much as 3000 amps at 480V 3 phase and it is not even expensive if the location has a power pole within 80 feet of the building. Then if you want to use traditional air conditioning then you can get yourself a 30 ton liebert CRAC unit and condenser that will run on 480V. For your mining rigs I would then use 225 kva 480V (input) to 208V (output). Now you have a voltage that your standard PSU can handle. Most PSU can handle between 100V-240V. Does this make sense? Of course this is for a massive build out but the principles are still the same regardless of the scope of the project.

[VoskCoin]

Alright so I've gone to 240v w/ metered PDU l6-20p wall plugs on 30 amps double pole

I need help with the fans, the shed will butt against a wall / hill so I'm thinking attic fans are the best choice here, mount them on the backside slope of the shed?

this will do   12 amps

so the above would do 24 amps  at 240 volts     which is around 40 gpus

2 exhaust fans high




I would argue in a 12 by 12 shed

using   this to feed in the air

cut low holes on one side of the shed.    say  6  and use the vents above.  inside the shed do  a bend up to cut down dust

                                              ^

if the intake vents  can face north  they would get the least sun.

if you silver bubble wrap the ceiling of the shed less heat from the sun

note I used it in the solar array

I'm thinking intake vents left front right, rear is backed to a wall / hill then roof mounted exhaust fans? I could wall mount fans on the top back portion if possible but itll blow into a hill and get some bounce back . .

We ran exterior grade ethernet from the house to our barn to take care of our internet out there. For coaxial, are you thinking of putting in a splitter from your service provider's coaxial line outside of the house to run to an outbuilding?

I actually just need to move it due to the awkward layout of the cord / gravel base -- now i'm thinking to just run the modem there and run a ethernet into the house to a switch / wifi extender . . awkward setup I guess lol


Also need to figure out this attic fan dilemma if anyone has any input!

You could certainly install some roof vents, this is a 1600 cfm example, but you can get more powerful ones if you need it. Just make sure you know what you're doing before cutting a hole in your roof, or get a contractor to do the job.

Do you have experience with these? I'm thinking of putting 2 in to begin on switches, and then one as many as I need to you know?

Cool project man! Good luck!!

Well, back when I was younger and in good health I worked a number of years as a general contractor, so I have installed a number of roof vents. I have not installed any for mining related ventilation. For general ventilation in places like a residential bathroom the rule of thumb is 1 cfm per square foot, but you would want more then that for a mining room. There is a handy little calculator for optimal CFM ventilation in a greenhouse. Since a greenhouse gets pretty darned hot , I think that would at least point you in the right direction as far as ventilation needs goes.

That's a really helpful link thanks for posting that . .  based off that and everything else I'm thinking 2 and I should be good to go? Going to install 3 and see how it goes? I'm hoping I can run simply one while my farm is small https://www.lowes.com/pd/Air-Vent-1-500-CFM-Black-Galvanized-Steel-Electric-Power-Roof-Vent/3126703

This seems to have good reviews, fit the idea in mind / sufficient CFM -- thoughts? about to pull the trigger and get this stuff done

how many intake vents you all think I need for 3 1500 cfm (4500 cfm) exhaust fan?

[btcgolong]

Alright so I've gone to 240v w/ metered PDU l6-20p wall plugs on 30 amps double pole

I need help with the fans, the shed will butt against a wall / hill so I'm thinking attic fans are the best choice here, mount them on the backside slope of the shed?

Thoughts on solar.. .  could it keep up with my usage?
https://www.lowes.com/pd/U-S-Sunlight-1-600-CFM-Black-Galvanized-Steel-Solar-Power-Roof-Vent/50146034

Would be nice to not tie up anymore power

Curious about the solar, how does it rate, can it move enough air?

Anyone try this?

Also, I'm researching now, but a solar powered gable end vent would be nice and easy to install.

nice thread, good job !

I would have put more GPU on each motherboard with PCIe risers, though

I'm actually going to be doing a build next week building one of the phil template "trio mining rig" to a 6 card rig, these boards have six slots, an m.2 slot as well but I hear a lot of bad reports of using m.2 adapters?
