You may be cool, but are you "using the earth for a heatsync" cool?

So my buddy built this gaming rig back in like 2010

 

  • i7 930
  • 6GB DDR3 (TRI channel)
  • 1TB hdd
  • GeForce GTX 480

He has since upgrade it to have 24GB of DDR3, a 512Gb SSD and a Radeon R9 380. Now, neither of us are swimming in cash so instead of upgrading his current PC we devised a fun little experiment. The liquid cooling loop to end all liquid cooling loops. GEO THERMAL.

 

The plan was to dig a trench underneath his house about 3 feet deep and bury some PVC pipe. We ordered an inline-pump and put it under the house and ran the power cable up through the wall and into his computer running it off of the 12V rail of his pcs power supply. We decided to liquid cool the CPU, GPU, and North Bridge.

 

We didn't think to take any pictures of temps before the experiment, so I have no way of proving our gains. But I have personally seen his Northbridge regularly hit 100C on air.

 

So we dug the trenches...

Ran the Pumps power cable up through the wall and into his PCs power supply. Then piped up the computer.

It's an early prototype with a custom built wall mounted "desk-puter". We drove the audio system with the amp you see on the left which also runs off the 12V rail of the PSU. The fans you see are only present so that the PSU has some gentle air flow. (The two fans to the right are intake, there are two more on the left for exhaust that are not pictured)

And check out these temps!!! Sub-ambient idle temps WITHOUT active cooling! (NOTE: The package temp sensor is inaccurate at this end of the temperature spectrum. 4c is likely incorrect)

Full-GPU load temps (FurMark)

Overnight Full system load temps with the CPU overclocked to 3.8Ghz. (The base clock on the i7 930 is 2.8Ghz and it has a locked multiplier. So we did all of our overclocking on the FSB...)

I'd say that planet earth makes one hell of a heat-sync!

 

What do you guys think?

Wow that is crazy. It is expensive but effective from the looks. Good job!

The entire project, including building the wooden desk from scratch costs about $100. My buddy had the trenches dug before I was able to get there and help, so the REAL cost was to his back. I've been assured by him that digging trenches underneath a house is NOT easy. xD

I think you just beat "Whole room Water-cooling"

Unfortunately, using copper pipe sounds like it was beyond your budget. 

You are correct, But we did considered it. We ultimately decided against it because copper pipe is incredibly difficult to protect against corrosion when buried

Due to the size of the cooling loop, I believe you will only be able to tell if it works if it runs cool for an extended period of time.

It would take days for it to reach an equilibrium. We left it at full system load overnight (pics in OP). Since the system will never stay at a full load for that amount of time, I think it's safe to say that it works perfectly for his use case. :)

I hope you are successful and it does indeed work perfectly for your use case.

Stuff- k70 with reds, steel series rival, g13, full desk covering mouse mat

All parts black

Workstation(desk)- 3770k, 970 reference, 16GB of some crucial memory, a motherboard of some kind I don't remember, Micomsoft SC-512N1-L/DVI, CM Storm Trooper (It's got a handle, can you handle that?), 240mm Asetek based AIO, Crucial M550 256GB (upgrade soon), some hard drives, disc drives, and hot swap bays

For some reason this reminds me of the person (probably from there) who routed his pool water to the computer.

I have a blog! And a list of guides I've posted

Water-to-water heat exchangers!  You have a dirty side and a clean side and don't let dirty water run through your desktop.  

 

A ghetto heat exchanger is dunking your radiator in a tub of dirty water, but it doesn't end particularly well:

Let's try to get the attention of LMG. I'd love to see them do one of their outlandishly expensive builds with a geo-thermal loop. They might even beat their personal OC record that they set here
