Cabinet Mining Rig Build

[Hagrid]

I built a miner cabinet from a cabinet I bought on Amazon.
https://www.amazon.com/gp/product/B004HLU7CE/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

It has a 18n exhaust with fan which will be attached to the ceiling. The intake is through a 14x25 air filter housing. The wiring is 6ga 240v which is on a 50a breaker. The sub panel has 3 15a 240v breakers. The 50amps would give me 9600 24/7 wattage. Each 15a will give me 2880 safe watts. I will have a rack inside to hold the video cards and the motherboards will be attached to the side of the walls. This will allow air to flow up from the bottom. The bottom fans will be 2 12" high flow fans. I also have another 2 that I can install in the middle. I have the main breaker and wiring installed I just need to move the cabinet over tomorrow and hook it up.
I put in 6ga wire which should handle 60a but I do not need that much wattage, so 3 15's will suffice.
My son decided not to mine so he sold me his cards. I put 8gb on each machine just because I already had 4x4 ddr4 sticks and bought 8gb more.

I will run 5 1080ti's on 1 plug, the rest will go on the other 2. I might get another Asrock ab350 pro 4 combo for any extra cards I can get. I run 5 on each MB about right now, but in different areas of the house.(dont want to overload 1 circuit)

I also have a 20a 120v breaker that will be dedicated to it as well. It is already there since it was for a fountain. I just have to pop it through the wall. This will run the fans and stuff. The 1060's sip power and can run 5 on a 850w PS no problem. I only have all cards at 70% power limit. I am not sure if going over that will result in a lot more.
I will have some pics when I am done with it.

so the SO got tired of having GPU's all around the house? Would be nice to know what your temps look like for i have one of these as well.

Since it will be inside the house pulling fresh air I am hoping they stay nice and cool. I might install an attic fan as well sometime.

++ subbed for updates. Curious to know how your temps are.

I have a small closet with ~ 2200 watts worth of stuff in it and an oversized bathroom vent fan. I unfortunately have to leave the door open (even with the 4" ac vent).

I went with 8" and also have another 8" assembly. I would try the 2 8" fans in series and if that did not work, I would just cut another hole on top and vent to the attic.

I corrected the fan size in the original.

Nice! Thanks for the play by play

I must be doing something wrong. I got 3 - 12 cards rigs and a 4th coming up. And I am freezing. I has dropped down to 30 degrees in my house. I have to run my heat or freeze.

Must be nice. It is getting warm here. 80's already. Not the best climate here in AZ for mining. The cabinet will do the trick!

 

[Hagrid]

I was going to drill the hole for the 120v line that is run past the spot where I need it anyways. I look at the wire and it's not shielded and it's like 16/18 gauge. Hell with that. So I had extra 10ga and installed that instead. 30 amp 120v is a bit overkill but this is [H]. I will never use anywhere near the capacity of the 240 or 120 lines. I always use a gauge higher that what I need. I am sure some people were like WTF is he using 6 gauge for 50 amps!? It's a few more $$ but I think it's worth it. It was NOT fun dealing with the 6....

Going to Lowes right now and pick up some more goodies. I also will order a few temp sensors that will mount on the outside with a probe. I think it would be nice to monitor the incoming, outgoing, and middle temps?

 

[Hagrid]

I have the exhaust done. I am just waiting on some ESD mats for the MB's then I can start on the inside.
120v is done and tested. I have the 240v done but will be trying it today with a PSU that I don't really care about. I have never run a PSU on 240v.
The filer is actually 12x24..... Exhaust fan is a bit loud, but that is with the doors open.
The exhaust tube has an R6 value. Anything is better than nothing.

 

[cpuspeed]

u can wrap more insulation around the tube and then use mylar emergency blanket around that to keep the same pro look.

Yeah, I still have 15 feet or so of the insulation I can always use that. I think it should be good.

I just tried the 240v. No bueno. Installer's fault. The house is the old code of using the ground and neutral wire on the same bus bar. The new sub panel has the 120v neutral bar which I had the other hot wire on. A quick switch and it works.
The power supply worked like a charm. I was sweating balls for a bit....
Dam Id10T errors!

 

[hlfbkd420]

add some LEDs too ☺ ... So its [H]

doesn't feel as good though.

I have what doubles as my walk in closet setup for mining. right now I'm pumping the air to my furnace intake to send through the house but I have a dryer vent option ready for when I need to dump the heat out. I am planning for more cool air being pushed into the room than what I'm trying to pull out. My room is bigger than this cabinet but you still need to think of possibly forcing air into that room.

 

[Hagrid]

It looks a mess but it is working. I have room for 1 more motherboard. I am not sure why the MB did not like 4+ GPU's. I updated the BIOS and tried the above 4G thing. I will look at that later.
8 of the 06G-P4-6163-KR EVGA 1060's, 5 of the Hybrid EVGA 1080ti's. I still have 3 of the 6163's, 2 6162, 1 6160, and 2 RX 580's left. I have the 1600W EVGA and 1200W EVGA left over as well.

I will try temps this week with the doors closed. I did order a 2x more powerful duct fan. They are running on wireless adapters until I hook up the cat 5 tomorrow. The power supply's used were 2 850W EVGA G2's and 1 1000W EVGA Platinum. I have an extra motherboard that I know runs at least 5. I am not sure I will put it into the cabinet unless temps are good. I might just have 1 open rig in the garage or I put a few in the empty 4U cases I have and pop them in the rack.

Each 1060 is around 85w @ 75% and each 1080ti @ 70% are at 200w.

Just curious and I am not a miner other than Nicehashing on my 980ti for fun:

I see you are using hybrid cards but I have not seen others using them. Is this because the higher cost means higher payback? I would think a hybrid card would be a great solution when combating heat in close quarters like most mining rigs are setup.

 

[Orddie]

i think you can do better on your 1060's. we run at 65w and depending on memory get between 19-23 M/H using windows.

Hybrid and liquid cooling don't actually reduce the total amount of heat produced, they just move it further away from the source and to a bigger surface area (the radiator) so it can be cooled by larger or more fans.
So if you have the whole thing in a closet it's going to heat the closet up just as much.

It's easier to direct the heat with the hybrids.

I use nicehash so memory does not seem to make a difference. 70% is good and they stay pretty cool.

 

[Hagrid]

I am taking 2 1080ti's out and putting 1 in each of the kids comp's. The middle son has a Titan so he is good.
I told them that when they don;t use the comp, they need to run the miner. Might do that tomorrow.

 

[hlfbkd420]

Do they get to keep the profits?

 

[Hagrid]

Do they get to keep the profits?

Hell no!

Today I will install the other 1060 6gb's in. I am also building a new comp for my middle son. When that is done I will work on the 4U case for the misc gpu's.(2 rx 580's, (1-2)1060 3gb)

Just installed the new exhaust fan. It is 3x the CFM rating of the other and is pretty quiet. The doors close and the sound just goes away! It is super quiet.
As some have said I definitely need something to blow the air in. When I close the doors I can feel the vacuum sucking them closed. I am not going to put a 4th miner in their and instead come up with a solution for the intake.


I have a big 79" rack in the garage, but am still worried on the heat. I have 3 4U rack cases.
It gets probably 100F+ or so in there in the summer. Never actually measured it.
Anybody here have run any GPU's in 100-110F heat?

its going to be a lot hotter in there if you add 3 cases full of gpus....

Inside temp is 77.7F and exhaust temp is 82.9F. I put a high velosity fan at the intake where the filter is at. I also added another 1200cfm fan inside.

The back of the tower, I would add an exhaust to the outside which is already there. It would be easy to fab a backplate up.

once you start getting into 50c+ ambient, you can expect some issues. Not all power supplies will be able to handle that kind of heat either. But if you can exhaust some heat out of that space, I think you'd be ok.

Well dam.. I do have a second cabinet built just like this one sitting next to it. I could start a new build on that one and just transfer one of the breakers over, since 1 will run the whole cabinet much less 3 outlets. haha

What you'll later find out when you are blowing air into the cabinet is the ROOM itself may need air pushed into it. it becomes a domino problem where if the air is being blown out of the house you will end up getting to a point where you need more outside air coming in.

good point

 

[Hagrid]

Update:
So the fans inside kind of sucked. This is a 4500cfm fan. It blows a crapload of air. It also opened up a good space for a 4th MB with some room to spare. The cover is an industrial fan cover. Seems to work good and does not limit too much air flow.
I am not sure if I have room for the 580's so they might be up in the for sale thread pretty cheap.

And where is that fan located within the "closet"?

 

[Hagrid]

And where is that fan located within the "closet"?

It is about 4" from the bottom. I have it 1/2 way in the closet so all the dust has to go through the filter first. It pushes air out of every orifice. Keeps it under 90F when 78-80 in the house. At least that is what the thermostat says.(2 of them, might be a few off but close enough)

 

[Gilthanis]

OK..so that is an intake fan and is about mid height. Good to know. One year when I actually get to one of the many fantasized projects, I would like to build something like this. It is a good reference.

How loud is this setup? And do you think it can be improved by adding some of that foam used for sound rooms (packaging foam and the "egg carton" bed tops for us frugal people) without adding too much heat insolation?

It is actually only 4 or so inches from the bottom.

OK. so this is version 1. Yes, the fan is a little noisy since it pushing a crap ton of air. Still can hear the TV just fine and such.

Version 2 I have though about. I would have the fans in a box on the bottom with the fans facing up.(or from the side) The box would have a house filter frame in it. The rest of it would be boxed in with a door in the front.
This would be super silent as V1 was similar but the fans could not suck air through the filter efficiently, but was very quiet.
I will have pics when I get the stuff for V2. Since the space it is in will be mine next year, I want it to be quiet for my VR. I plan to have 2 of those fans. That is massive air movement so I might up the exhaust to 12"-16".(Not sure it matters much with the amount of air I am pushing through since it comes out of every crack)

EDIT: Thinking about it I am not sure a fan for venting is necessary? The fan is pushing so much air through I am sure it has no problem getting out. Maybe just enlarge it.
