Adding a second rig to my loop

[Thick8]

My wife want to play Elder Scrolls Online with me. I've had an Intel 4790 machine just sitting collecting dust for the past several months. The only thing it was missing was a GPU. Well I won a gigabyte gtx 1080 ti waterforce on Ebay for $700 so now it's time to hook this rig into my geothermal loop.
My plan is to use another open frame case on a shelf below the one I currently have. Right now there is a MCPX2 dual pump on a Ryzen 1700 and a 1080ti. My plan is to add my old Apogee Drive II waterblack/pump to the Intel CPU to add a little pressure. I never run my pumps above 20% becuse the CPU never gets hot enough to raise the speed.
So the loop is going to go res, dual pump, Ryzen, 1080ti, Apogee pump/block on 2nd CPU, 2nd 1080ti, heat exchanger. I'm thinking I should run all the pumps off my main rig as the seond rig won't always be running when the main one is. I don't forsee a heat issue as I was running a 5+Ghz FX-8350 and a pair of OCed 290s prior to what I have now.
Anyone see any problem that I might be missing?

Well for advise it's tough. You're using words like Geothermal and Heat exchange with very little detail. Geo-thermal like a faucet to drain? Heat exchange like a single stage chiller?

Sounds just fine to me, how large is the overall setup of your your 40' thermal field? (is it linear or coiled)

What load temperatures did your single setup yield?

Also how did you achieve getting it 35' down in the ground, as that's pretty deep?

Edit: I seriously considered doing that myself but where I live I would have had to go a minimum of 25' down and the wife already thinks I'm nuts anyway for the cooling experimentation I have done so far!

Look up his GT loop.

Haha, I looked in his sig. had to put my readers on though...

25’ is nothing if your in the midlands or low-country.

I remember that thread now.

You reached that depth water well drilling, with a home made copper heat exchanger at the bottom of the hole.

Which you actually never showed any pictures of, just a text explanation of it's construction.

Yep that’s the one. 3 years later and still cooling with no reduction of efficiency.
Really wish I would have taken a picture of the heat exchanger...

I ended up getting 2 cheap open bench stands and modifying them slightly so they would stack one on top of the other. Took a little trial and error of course to make sure everything would fit.
The plan was to get some more clear hard tube to repipe the two systems into one. So I ordered the tube and then decided to use some PEX to get an idea of the runs and bends I would need. I had no idea that PEX could be heated and shaped like acrylic. I was also unaware of just how tightly both PEX and acrylic could bend while maintaining its shape. I’m running it with the PEX for now until I decide what changes need to be made. I had no clue it would work so well and was so easy to shape. Much easier than acrylic. And the writing washes off with a little alcohol.
The PSs are mounted on the bottom. I cut a piece if plexi so that it would sit in the grooves of the aluminum supports and applied some limo tint to it. This hides the PSs and cables nicely.
The next level houses my wife’s computer. It’s the i7-4790 and Zotac 1080ti Arcticstorm. The Apogee Drive II pump/block on it is hooked to my PS and MB so my machine has to be running for her machine to be on. I ran the system with just this pump running and it worked fine so I may hook it to her machine just in case my machine shuts off for any reason.
The top level is my machine. A Ryzen 1700 And Gigabyte 1080ti Waterforce. The MCP35X2 dual pump is driven by my machine.
All three pumps are turning at about 1400 rpm so they are very quiet. I had replaced the Corsair 850 PS fan with a BeQuiet fan so it’s nearly silent and the EVGA 1000 PS has a very quiet fan already.
After running for a couple of weeks now I’ve determined that I will have to put the SB and memory coolers on just my machine as they are little heat factories. Running some temp,tests now but so far neither CPU is going over 54c and the GPUs stay under 46c. Water hasn’t hit 30c yet after 4 hours of heavy multi-core gaming at 4K on both machines at the same time. Probably won’t do a real test until the SB and memory are under water.
