I am very impressed with sincerity of your effort and workmanship. Much to learn here.
However, I have to question economic viability of this project, due to your need to pay for air conditioning.
Air conditioning in Dallas will probably triple or quadruple your power bill, compared to a naturally cooled installation, and cost of power may make bitcoin mining unprofitable much sooner than for those without the need to pay for A/C.
True the ac doesnt help. It uses about 1500w, or 3.5 oc'ed antminers worth of power. Based on my power rate, thats about 3.64 USD per day. Not horrible. Not great either. Also, if we leave the door to the shed open when home we can shut off the AC.
If you do not need AC when the door is open, then what you need to do is get rid of the AC, and instead install an exhaust fan. You will pay a fraction of the cost of electric bill.
There are already two exhaust fans. They were not enough to keep the shed cool enough. One is an attic exhaust fan. I also cant leave the door open during rain or when I am not at the house.
good work. I can't keep mine cool enough either......July in TX will be a challenge
No doubt. As the business partner Shaxs referenced, it's been a fun challenge to organize, structure, build, wire, and administer our little frankenstein shed. Having said that, I'm extremely proud of what we've been able to put together, and am extremely curious to see how it performs in the Texas heat. We also have 6 more miners on the way, so there will be more wiring, positioning, and administrating.
I may try out building shields for each of the units as well. I've seen some folks use cardboard or aluminum, and I'd like to see if that can drop the temps on the units, even if it's just by a couple degrees. Never-ending tinkering!
