That's a pretty good idea for propping up the GPUs. Are you worried about unequal air flow over the GPUs that are at different heights in relation to the fans?
The top shelf is a bit warmer than the rest, but it really isnt an issue.
great project, i havent read the entire thread but what have you come up with for reducing moisture in the air and filtering
my garage is set up similar, although much smaller scale.. but i leave the back door open for fresh air intake and air pushes out through ridge cap in the roofing and soffit vents
I've not solved the humidity issue, but i foresee it being a huge problem. I have found corrosion on one GPU. This must be resolved ASAP!
I'm open to suggestions. Is there some large air blower that i can feed air into the shed that doubles as a dehumidifier or something? I need to set up some conditioning of the air.
