Topic: Garage Mining (Read 3173 times)
A shed was a though I had early on based on yun9999's build. It does not look like my HOE will allow that though. For now I am limited to what I can easily cool in the garage. Once I get to a return on that investment I may consider leasing a space somewhere and going bigger, Much bigger. OF course that said, assuming the profit margins still make it worthwhile a few months from now.
Instead of clogging your thread I made my own and some other great members already added a lot of good info in it may be worth a look to you

I'm dealing with pretty much the same problems and by the end of next week will have similar amount of rigs going in there
Ultimately it seems that one way or another we need to have an intake fan and exhaust fan as thats the only efficient way to do it. .

Having both an intake AND an exhaust fan is redundant and usually a waste of electricity - the only thing that does is reduce backpressure a LITTLE, does not add significantly to airflow.
Have you considered putting louvres in your garage door, as opposed to drawing air in from inside your house?
I have since changed plans to simply modify a shed with louvre intake and exhaust fan outtake. . just trying to figure out what fans currently
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").
awesome to see another washintonian on here lol! 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).

How are you guys able to set up so many rigs? Did you guys have to have an electrician come out? Aren't you overloading the circuits?
Many of us have an electrician add additional circuits if mining at a residence.
My limiting factor will likely be cooling long before anything else. The 6 month goal is to be at 10 rigs.
you can do good with 3 fan in front of the gpu and for exaust you can use a tube with radiators to direct the air outside, or what about an air conditioner even better no? just put the temperature to 20° and you are done
It would take damn near a 5 TON AC unit just to cool the rigs and it would run all the time. That is not cost effective in any shape or form
you need to exhaust the heat out using fans

Do you have an option for a shed? I've scrapped my plan here https://bitcointalk.org/index.php?topic=1907942.new#newbecause it's just not feasible for the way my garage/house is setup and will have to go the shed route

I honestly havent done anythign with surge surpession yet. I will likely install something on the main panel for whole house surge suppression. MY main breaker panel is directly below where the miners sit in the basement. I have been running 2 outlets up there on a 20amp breaker to do 2 miners per breaker.
At that rate how many max miners do you think you'll be able to achieve?

I believe the cylinder fan with a duct is probably the way to go for me. How do you guys determine the required size of a fan though?
What's your plan for outlets / surge protection?
As far as fan I'm trying to figure that out myself lol normally it's based on sq ft but our situation is a bit different

This was some of their recent input, you could potentially apply this concept to your setup
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

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.

The only issue with that is my master bedroom is directly above that. Currently the only way for the heat to get out is out the garage door. I was thinking of using something like this.

yea that will work make sure you get at least a 2000 cfm model or more
Why do you say 2000CFM? Is there some math you were able to do to determine that, Something i should make myself aware of? I have been struggling with fan sizing and how to to know what I need.

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.
install a downblast extractor fan in the celing, a heavy duty like this

3000 or so CFM should be enough for that amount of rigs.
you can probably get cheaper one on ebay or Amazon or used one
