Garage Mining

[Icarusfixius]

So reading through things here is seems that there are a few of you mining in garages or sheds. It would seem advantageous to do so to use outdoor air to cool the rigs much cheaper than running the AC harder.

How do you overcome the humidity? Is that not much of a concern?

I currently have 5 rigs running in the basement and have no good way to exhaust the heat. As such my basement is now 94F. I need to come up with a different game plan. Wondering what tips and tricks you all may have learned over the years and what makes the most sense to do?

Do you have any windows in the basement? You're abandoning the basement idea and moving to the garage? You should install 2 vents at the top and bottom of your garage door, that's what a few other people have done on here.

This is my favorite shed setup that I've seen https://bitcointalk.org/index.php?topic=1806061.0. He's in a very humid city and it doesn't seem to bother him, from what I've read the biggest struggle is dealing with high water.

I wouldn't build a shed for only 5 rigs though, that's a lot of hassle. You could easily run that in a spare bedroom with some minor electrical upgrades (50A drop).

I ran into the same problem.  I have 4 rigs up and running right now (5th should be ready to go on Monday) I had to move 2 from the basement to the garage but am a little shy about moving a 3rd out there until I have an electrician buddy of mine come and check out what I have as far as power there. 

We are planning on building a new house in the next few months and I plan on having a few extra lines run to the basement near a window.
I hope to build a room and use one of these..

Yep, I have seen his stuff he has a very nice setup. I don't recall ever seeing it mentioned what area he is located in? I was trying to avoid cutting the garage door and was thinking of maybe putting a window in the garage. Ultimately, I would prefer the basement but I dont think there is any effective way for me to move that much heat out of my basement.

I have seen those before and while the though seems nice I am afraid it is just going to be inadequate to keep up. If my math is correct it would take one of those per 4 rigs. That seems like a lot of extra cost and power overhead per 4 rigs.

no no no no no

it is 9.4 seer  not efficient

give me a minute

do you have a back door to the garage. like this just open it and use fans to pull air out of the garage

[Icarusfixius]

I do not have a back door but I debated installing one or a window just for that reason. I am in the midwest though and I fear those %90 RH days. I dont know if that is a real problem or not

okay  can you do 2 windows

 try 2 of these  fans one blows air in one pulls air out the garage.

if there is a humidity issue replace the intake fan with this ac which is 12.1 seer.

make sure the exhaust fan is sealed  on the sides of the window so it won't let in humidity.

I don't know if there is actually a humidity issue or not. That is what I am wondering. At what point do you guys worry about it? or not at all?

It can be an issue if it is too high , can cause water condense on the hardware , and sure you know water and electrical components it will lead to short circuits , you need to find a way to solve this humidity issue maybe not letting your hardware to cool down alot , raise the temp. a bit to reduce water condense

I've been contemplating the same thing,

My garage has no windows, garage door, and a door. I guess this is similar to OP.

Virginia gets pretty hot and humid, how would I create a proper setup?

It seems I'll have to run a commercial style AC unit and a couple large fans to circulate air.

I am in NJ  humidity  lasts 3-4 months.  Been garage mining since 2012  no rusting yet.

most of the time the hot gear solves all humidity issues.

A/c only works if power is dirt cheap .

otherwise it is too costly.

I have a back door that i open 3 to 4 months a year.

when it is hot I scale mining done when it is cold I scale mining up.


i.e. 2.5 kwatts june 1 to Sept 30

5 kwatts October 1 to May 31

The door is essentially my front door, I don't know if I really have an option other than cracking garage door/ opening and putting an intake and exhaust fan? What about inclement weather?

[szafa]

I dont have garage only home.What i know garage under earth have lower temperature.

Would small box fans such as those be adequate for up to 10 rigs or so? Seems like you would need to move more air but I dont really have a good baseline. On one hand I need to just get started and move forward (trial and error). On the other I dont want to spend money on things tat ultimately end up useless because they are under or oversized.

[wheelz1200]

Dont know what your garage set up looks like but you can certainly instal one of these mini split AC systems.  They are ductless and efficient.  If you do buy fujitsu.....dont buy any knockoff crap if will bust in a year.

If your garage has a good seal then this will help with heat.

[Sequoia93]

Would an A/C really be that efficient while you are also circulating air in/out of the garage with fans?

Also, has anyone tried anything like this?

http://www.homedepot.com/p/Master-Flow-4500-CFM-24-in-Direct-Drive-Whole-House-Fan-with-Shutter-WHFS24M/100018252

I believe @yun9999 says he has two 5000CFM fans for ~200 GPUs in Texas. So one of these in the ceiling, and some vents in the garage door should be plenty for about up to 100 GPUs just about anywhere, no?

 If your mining room is 10 degrees F or more above ambient, you don't have to worry about humidity.

 In my case, even when it's raining outside and I have my largish Brisa Evap cooler running, I only see 40% or so RH at the most, and most of the time closer to 30% - but that's with somewhat over 15KW worth of mining gear running.

What area are you in if you dont mined me asking? How well does the evap cooler work?

[QuintLeo]

Central Washington - and the evap works quite well, most months we only see 2-3 days it precipitates at all and I rarely see 40% humidity 5 feet from the OUTPUT of the evap.
 I'm thinking I might need to get a second one at some point once I move into the new place I should be relocating to in a month or two (better ventilation than where I'm at now AND twice the power availability).

 Semi-arid biome, bloody near a desert - I think we average 10-12 inches of rain/equivilent a year or thereabouts.
 For an evap to work noticeably better, you'd have to move to an actual desert like the Mohave or Death Valley.

 There's a reason the Grand Coulee Dam was built primarily to irrigate the region I'm in (the power generation was a LESSER design function in it's initial buildout, a lot of the power generation was added in later "upgrades").

Miners have been moved out to the garage. During the day with an ambient temp of 85F the garage has been reaching right about 100F. I have a carpet drying fan blowing air out underneath the cracked garage door but it doesnt seem like that will even begin to put a dent in the temps. Not ideal anyway as it is exhausting heat from near the floor. I was thinking of using one of those air extractor fans with a duct to draw hot air away from right above the miners and blow it out underneath the garage door. I feel like that would be better but perhaps still not enough. I currently have 4 machines out there but would ultimately like to have somewhere between 7 and 10.
