The prices on the 580s have gone up by at least 50% of what I was getting them for.
One of my ideas wasn't to exactly water cool the GPUs themselves but to do something similar using geothermal. I have a backhoe so digging ain't a problem, ya know? I was going to bury a 2k-3k gallon reservoir, run a bunch of pex and then pump that through a series of radiators (having a former automotive shop I have a lot laying around). The radiators would be in essence a precooler for my geothermal heat pump that will only work in AC. The colder the incoming air to the exchanger, the cooler the ouput will be. If I can take 105 degree Texas summer heat (or even the exhaust output of a closed loop system) and turn it into 80 or 85 degree air before it hits the AC system, my AC system will be way more efficient. I have the majority of the items already to make the precooler, and even the AC system. Just need time.
I started this venture in January so I have no idea how I'm going to cope with the heat. Painting the containers a semi gloss white has definitely helped cut down heat absorption and I expect the solar shade to equally help.
If you wouldn't mind, I might need a copy of that script you wrote!

I was going to use automotive radiator also, but you cant mix dissimilar metals, copper and aluminum dont work well and you would have major issues down the line if you tried, thus why i had to source an all copper radiator. i managed to find one on ebay after some careful searching, but my plan B is to add more length to the loop, i have plenty of property still and may even try running some of it down into the earth vertically, someone posted over on another forum that i can purchase some pvc pipe large enough to allow the pipe to run down vertically and use water to frack the sand out by running the water hose down the middle as i disturb the soil with the pvc pipe, then afterwards run the cable down the middle, but im worried it would kink or whatnot. Another way someone mentioned was i could purchase a/c copper line and build a diy radiator without the fins.. idk i just hope the temps stay managable for me, since i spent a few k redoing this system multiple times, mostly on pumps failing (sigh)... my current pump that has lasted the longest is a simple submerged utility pump rated for 100% duty cycle at 80% load i picked up off local hardware store...
In regards to the code let me see if i can find it, what the script was just a simple nvidiainscector batch file to change GPU settings, but i added the lines to run it continuous with a pause for 720 minutes, then after the 720 minutes it would run the next line of code and pause for 720 minutes to run the next lines of code. basically i started the batch on the rigs at a set time of the day manually to keep it stupid, the pauses were 12hrs, so 12hrs during the middle of the day it would run one set of overclock settings, then after the pause would finish it would run the next set and it just looped back and forth over and over 24/7
