Wow, you blew $4500 just setting up the room! Kind of defeats the purpose of mining. It's hard enough to make a profit without piling another $4500 on top of that!

Hosting would have been anywhere from $1,100-1,300 per month, per person when we only had 15-20 miners. With what we have now, we will hit full ROI in another 2 months or so, maybe less with the spike in price... Pretty easy decision in my mind, and I didn't have an issue putting my money to that.

Trust me, we weighed every option we could, and this was the best option, hands down!

Awesome farm! I was thinking about setting one up for a couple of GPU rigs but nothing on the scale of what you're doing. I love the wifi controlled lightbulb, that's a really good idea.

Have you run into any issues with the miners since setting them up there?

Are you up to Fire Code on that building? Since it is connected to your home.

Code specifications would be great if given. And what code specs did you go by or did you overkill on the codes? Overkill on codes is a great thing.

Thats a good question.... probably not up to code exactly. The shed sits on an external slab backed up to the exterior of the house which is cement board (deem as a non-combustible material). We also have a nest protect in there for fire/smoke warnings. In fact it went off last night I think because there was a fire somewhere outside (you could smell it) and the fresh air intake brought some in.

Just a warning, google recalled a lot of nest. Becareful, man. Hope you live by yourself and not with children, wife & pets or putting someones life at risk including yours.

Only recalled because of the wave to dismiss option.

^ha, how did that feature slip into the final product?

*nest senses fire - send alert*
*humans rush into room on fire and flailing - wave to dismiss activated - returning to standby*

so after sealing up the wall we're sitting at 86 degrees f on the cool side and 124 degrees f on the hot side. This is with the 32 miners running, and it isn't extremely hot outside yet. Shaxs and I are going to tinker with individual shields for each miner to try and contain the heat they put off so it's funneled directly to the hot side instead of outwards towards the other miners.

This is like the never-ending project...

sounds pretty fun and successful though! 32 miners is a lot of heat - are they overclocked or undervolted?

whats the outside temperature? and as mentioned, what is the noise level like outside the shed - 32 S1 units make a LOT of noise when you dont have a wall between you and them

All over clocked. Outside temps were in the high 80s F.

Noise level is not bad unless standing next to it. No worse than the noise from an AC unit. I cannot hear them in the house.

So your power cost including delivery is around 10ct? is that correct?

also, cooling typically adds around 30% more power consumption when running at full load, so it isn´t that much more power cost.

It is a necessity in most parts of the US anyway.

From my experience, antminers aren´t that sensitive to a higher intake temperature of say 30°C.

they can run fine in a room at 85f which is 30 c

but he is in texas which means 100 f or 38 c

guess that's what i meant to ask above.

OP: would you skip the AC unit in favor of simply using outside 30C air (at peak hours) in your shed, and if not (due to limits of the current ventilation CFM?) do you think a shed with larger vents and fans would be capable?

second part: is running an AC on a very small amount of intake air very effective if the air is being used and vented out hot within a minute or less? and does doing it that way mean it will add less than 30% (the general figure for closed-circuit cooling of heat) because the intake air (30C) is still significantly cooler than the exhaust (45C)?

lastly: whats the noise like? does it sound like a pool shed or does it sound like a vaccuum/box of fans when you stand outside or nearby? (ie: would it annoy the neighbours or be obvious)

So you have 8 antminers right now (~3.2kW) and he 15,000 BTU ac unit doesnt quite cut it? (15000 BTC should suffice for ~3.5kW). How do you intend to add more miners?

Im faced with a similar problem with the coming canadian summer (still hot enough that there will be a few 30C heatwaves), and am unsure whether to go with an air conditioned location (that will require a 100,000BTC A/C if not larger) or to form enough ventilation that i might just have to deal with 30C intake temperatures and a crontab log to underclock everything during the heat of the day.

If you were doing the shed over again, what would you change?

would you make it smaller / would you triple the number of ventilation holes and run on pure airflow / would a window-mount AC be more efficient?
and, would having the ac on an inline airflow with all the wasteheat dumped outside prove more efficient than cooling the entire cold side of the shed?

I need a good plan to handle 10kW (if not 25kW) of heat

No, we have 26 currently. Adding 6 more tomorrow. Doing it over, I would make the cold side smaller and the hot side bigger. I just spent 2 hours today moving the middle wall up another foot and a half to do just that. This will make the area the AC is trying to cool smaller, put the ac closer to the miners, and give more room in the hot side to trap hot air and expel it. They key is to funnel as much hot air into the hot side and evacuate it quickly. Shields on the antminers might help. We might play with that next. I dont know... I dont want to spend too much more time on this. These dont need to have lives of years as they wont be worth it in a while.

From what I read, split AC systems like the one I got are more efficient than window units. I might upgrade the second exhaust fan to another 1350 cfm one over the 650.

Im not sure I understand what you are asking here "would having the ac on an inline airflow with all the wasteheat dumped outside prove more efficient than cooling the entire cold side of the shed?"

my guess is the ac blows its cold air directly at the intake fans.
-------------------------------------------------------------------------------
I do have this suggestion buy these

http://www.ebay.com/itm/151276722479?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

assuming the seller has more of them. he charged me 107 usd for the 14. add them like this. this will really help pull the hot air out.

also if the oem push fan fails on any ant these will protect that ant from over heat.

these move air like a mofo

Quote from: philipma1957 on May 01, 2014, 04:52:29 PM

if you do not mind the noise these work great. these are delta 38mm fans loud but 160 cfm. I got them on ebay used 14 for around 110 bucks.

my gear is running at 45 c in a 84 f degree garage

they run push pull

they attach with 4 pipe cleaners and 4 nylon nuts

they power off the miner's power

Nice illustration.

The problem I see is that the entry door is on the cold side. That makes it harder to insulate and cool in the summer. When it hits 100, it's going to be tough to keep it frosty in there. It would be cool if you could rotate it 90 degrees so that the hot air is blowing directly at the exit door. Make the cold side airtight with insulation so that your HVAC is pumping cold air into a sealed cooler, and the only escape for the cold air is through the Ants. No insulation on the hot side. But what do I know, I haven't even seen the thing.

That is a great point. Unfortunately I am stuck with this configuration due to the large holes cut on the "hot side" that contains the exhaust fans. I might try to insulate the door area of make it more air tight.

Awesome project. I admire the DIY gumption of this.

From the pics, it looks like the cold side faces the shed door. Is the hot side up against the house?

The hot side and cold side both share the wall with the house. Here is what it looks like:
