12 Feet Under: 1000 Square Feet of Geothermal PC Cooling - Page 18  

post #171 of 340
Thread Starter 
The water temperature of the house section of the loop has equalized to 50f or exactly 10c. It was only slightly lower when I turned it on this morning, so the full effect of the 30f night didn't transfer to the thinly insulated crawl space piping.

I couldn't resist hooking up a heat source and seeing how much the temperature went up over time. An overclocked 5970 is the hottest thing I have until I make the 1500w heat stick.



That's all I felt comfortable recording for now because I don't trust with barbs with the waterblock's mini spacer in them. There are so few threads attached to the block.

The idle core temps were 10c and 12c.

I need to get the coils finished for above the ground chilling! It'll be colder on the ground than when its deeply buried. Until the sun comes out anyway.

Edit: The 10c water temperature is in the ballpark of what I'd have if the piping was buried and all finished. So those 5970 load results would be about the same. The same or better than my current idle results (20c/21c) in an 18c ambient.

God you are insane! I wish my mom would let me tear apart the yard and house

Well she probably would since she really doesn't care XD

This is why OP is single.

Uh oh. Not having an o-ring between the spacer and the barb is allowing water to very slowly escape. J-B Weld would be a permanent solution to connecting the riser to a barb but I'll try some (removable) rector seal first. Its never let me down before. The spacer isn't needed on the acetel side of the block so I might use that side and make the card removable by hidden quick disconnects.

I've broken down my dual loops so I can combine them with the heat exchanger in the loop. That will help pass the time while waiting for the insulation this week. Crawl space chilling on demand.

teflon tape works awsome and seals any small leaks that might show up and u can alwayse revome it unlike JB

I've had many failures with plumber's tape that were fixed by replacing it with #5 RectorSeal. A Frick ammonia compressor mechanic introduced me to the stuff. Since then everything at work has been protected by it.

It's good for something like 10,000 PSI with liquids, 2,000+ with gasses, and is removable. Check it out if you haven't!

I'm going to screw two 2x4s "rails" into a 4x8 sheet of osb tomorrow and get the coiling over with. It's supposed to be mostly sunny with a high of 54f. There's always the heat gun too...


The house section of the loop seems leak free and I'm running everything through my (unplugged) pc's waterblocks as well. RectorSeal seemed to fix the water forming on the EK gpu waterblock's mini-spacer.

It's eerie being in the presence of silent flow through the blocks. Kind of like a silent heart pumping away. Seemingly dead, yet alive.

I was going to say "good advice" to shurik, but then I read this... lol

How poetic of you. ^_^ Ya, any insulation should deter condensation greatly, and having some absorbent material around it helps to wick away any condensation also, as per DICE pots w/ paper towels... You COULD lacquer, but eff that. You COULD coat your stuff with vaseline/gunk, but that's counter productive. You COULD dunk your rig in oil if you plan on cooling sub-dew-point.

Regardless, never forget the catastrophic powers of freezing water in lines. (I.E. Ice forms as a crystalline structure that expands, and as you know, destroys pipes, etc.) LoL good luck! Awesome work--it's good to see more progress. This should prove itself a very rewarding luxury.

yea i use something like that for gas fiting and sprinkler

but i had a few water blocks that would just all of a suden spring tiny leaks and teflon tape was right thier gave it a go and leaks wer gone

some ppl have problems with teflon tape they ither way over do it or dont put enonoghf the trick is to give the male thread 3-4 tight layers with NPT and 1-2 tight layers with normal thread
