Looks great. I too tend to scale back or shut off mining in the summer due to not wanting to exhaust all the cool air from my house only to have to power my air conditioner to recool it. Besides the added electrical cost, you’ll wear out your AC unit and have costly repair bills. It’s too hot where I live to get by with a mining shed or I’d be all over it.
The shed was the best decision I made in mining so far. It's been fantastic once I figured out the amount of intakes I needed. It took a bit of trial and error, but I now have plenty of intake and can filter the air coming in. I'll be able to regulate the intake too by increasing the MERV rating of the filters and using more restrictive ones if I need to. I may have went a little overboard with the intakes, but it was just over 90 F here and everything ran fine. Cards still were at 60C where I have autofan set and no issues. Plus my house AC didn't have to work even harder to keep the house cool. Now I just wish I ran more power to the shed. Maxed out on my 100amp panel
