Around 8 PSI after all the line losses, without the PC hooked in.

I'm posting at XS too because that's where I picked out my first non-Koolance WC components in 2004. The activity is definitely here though!



All the main components are now on hand. Except for some Norprene, Lowe's carries the rest of the items needed for the project. They're going to start repeatedly seeing me in the plumbing department.

In other news, I've decided to move the geothermal trenches location as far uphill as possible. It seems like the drier, naturally drained soil is safer bet to maintain a constant temperature year round. I'll still look into installing a ground temperature sensor deep in the bottom of the hill for comparison purposes. Another loop could be installed there in the future if the temperature results turn out to be more consistent.


Ground temperature sensors installation how-to




The revised overview:



The tentative schedule and to-do list is:

Friday: Uncoil piping outside to take advantage of the mostly sunny weekend. Visit Lowe's to buy up all their 1" PE tube insulation and all the items needed to hook up the utility room components. The computer area's Ts, valves, and adapters could be started on too. I haven't fully decided on the crawl space piping yet so I'll finish the inside areas first.
Saturday: Assemble the reservoir. Finalize mounting plans for the utility room components. A ventilated pump box for vibration and noise dampening purposes will be needed for example.
Sunday: Hook up the pump, res, and the filter upstairs to simulate the trench depth. Connect them to the ends of the geothermal pipe to check the flow and to ensure the fittings don't leak. After running it during the day to check for leaks, the pipe will have to be drained down the hill to prevent it from freezing overnight. Possibly cap off the piping to minimize organic growth?
Next week: Do measurements in the crawl space and to the planned trench. Start forming coils and zip tying the piping to its final form. Insulate the piping that will go to and from the trench with the black PE tubes. Start doing whatever it is I'll do with the blue sheets of foam (cut up strip layers? wrap around?). A rented trencher from Home Depot will probably be needed at work next week. If so, quickly borrow it to dig a trench from my house to where the pit will be. Start to bury that insulated piping with the blue foam surrounding it in some fashion. Receive and wire some temperature sensors to the coiled tubing with burial cat5e. Also bury it in the thin trenched line. Decide on, purchase, and insulate the crawl space piping. Possibly shallowly bury said piping with blue foam sheeting. Secure the pieces coming out of the ground to the house. Drill the four holes into the floor, connect the pipes, insulate and properly seal the holes. Hook up the geothermal piping to test the fully assembled loop. Install OWFS on a linux server and troubleshoot/finalize the 1-wire network. Phew!
Unknown: Wait for the ground to be reasonably dry and get the geothermal trench dug, lower the assembled coils in, and carefully back fill.
August: Learn how well it actually cools in the hot humid summer heat. Possibly declare victory.

don't get mad, but that seems like it's just way over the top, and wouldn't be the best way to cool a PC. don't get me wrong, it may prove to have low temperatures, which is what we are all looking for. but i would just settle for regular liquid cooling, or mineral oil cooling. plus do you really wanna dig 12 feet deep even with an excavator?

My system can dump a crazy 750w or so of heat into my loop so instead of adding more radiators to quiet my fans I'm pursuing this project. Both are overkill, but for me trying to push the limit has been the most enjoyable part of this hobby for me right now.

I'm not digging the trench, the machine's owner/operator is. He's actually been pushing me to do this and my plannings been the hold up for two years! The dig is actually the most straight forward part of the project and can be done in thirty minutes. A backhoe could go about that far but would take 3-5 longer. I'm going to collect temperature logs to help others decide if this type of project would be worth it for them, even factoring in a rented backhoe.

Since the equipments on site and the 300 feet of piping cost $72, why do this and make one hellacious radiator?
