anyone ever try it?

I dont have geothermal in my house but the thought just came to me. it would be interesting to a home with geothermal climate control and use it to cool a computer

dont know if it would work or not but it would be interesting

There are possibilties there, but the majority are looking to add heat (to homes), not remove it.
Typically, underground water is cooler than surface temperatures, and pumped through a closed loop system would be functional but not economical (at least not at this point).
A deep well would be required to draw up cold water, the water would require refridgeration to stay cool.

I just set up an evaporative chiller that uses air from outside a few weeks ago. It works well in the winter but in the summer I was considering using geothermal cooling. The only problem is that I live on the 3rd floor. When summer comes around I may try to get a really strong pump and put an aluminum radiator a few feet into the ground. If it it can keep the temps in that loop down to 50~60F then running that over my radiator should keep things pretty cool. I am basically looking for ways to get my computer down to pretty low temps in the most efficient ways possible and geothermal cooling is definitely near the top of the list. I think it will begin to play a major role in the heating and cooling industries in the future. If i can't set it up on my 24/7 rig I'm gonna dig a big hole around 8 feet deep and put a radiator and pump down there. I think its 8ft that you have to go down and then its a near constant 50F. This is definitely possible and please post pics if you do this.

Note: I do not recommend trying to run the same water through your computer as you run through the ground. I would only do this with a double closed loop system. The first closed loop being that running through your computer and a radiator or heat exchanger of some sort. The second closed loop would be that running through the radiator in the ground and flowing over the fins of the radiator from the computer's system. The other good thing about doing it this way is that it is relatively simple to set up and if it doesn't work just forget the geothermal and put some fans on the radiator for the computers loop.

I saw a website from a fella who was hell bent on eliminating any noise from his PC. He dug a hole in the ground and put a 50+ gallon water tank in and covered it back up. He they watercooled his system from this tank. Because of the tanks large volume and the grounds cool temps he was able to run without any fans at all. You don't have to worry about pumping because it's a closed loop, so the pressure balances out. The only consideration you have to make is for the length of tubing. I wonder if I could find that link again...

I just had another thought. If you could replicate the underground environment(i.e. a tub full of cold dirt you could test the cooling potential without digging a massive hole 8 feet into the ground. I am going to try this as soon as the outside temp rises above 60F. My roommate thinks im crazy with the evaporative cooler going out the window, I can't wait till he sees me putting refrigerated dirt into a rubbermaid tub.

What do you mean by "you don't have to worry about pumping because the pressure balances out". Wouldn't you still need a pump to circulate the water?

Yeesh! Bacteria infestation would be a nightmare!

I don't see why. It was a closed loop, and he can always dump a bottle of bactericide in there every few months.

You could just make the loop extremely toxic to all living things and you wouldn't have any problems.

I meant that you wouldn't have to worry about getting a pump strong enough to pull water from underground, of course circulation would still be necessary.

Ah, I see.

I don't think bacteria would be all that much of a problem if you just put a little biocide in the closed loop.
