Got this idea going on my AMD Athlon Triple Core Rig for less than $100. No fans, no radiators. Just a large quantity of distilled water with an anti-corrosive water wetting additive. The Results were much better than I expected..

Parts:

-200 GPH Submersible Water Pump ($8 after 20% coupon) Harbor Freight

-10' Clear 1/2" Vinyl tubing ($4.87) Home Depot

-5 gallon Bucket and lid ($4) Lowes

-5 gallons of Distilled Water ($5) Local Supermarket

-Water Wetter Additive ($10) Autozone

-Danger Den Water Block ($60 Shipped) www.svc.com

Victim

-AMD Athlon 455 3.3GHz Triple Core CPU, Overclocked to 4.125GHz

Results

-On Phenom CPU cooler at 3800 rpm, 59°c after about 2 minutes of Prime Blend (had to stop due to increasing temp)

-On Fan/Rad-Less Bucket Cooling, 46°c after 3.2 hours of Prime Blend (water temperature went from an initial 64°F, to 87°F after 3 hours) ambient temp was at 68°

I dropped a pair of 2-Liter sized ice chunks into the bucket to go for even lower temps, but condensation became an issue before I could begin some bench marking.

I was able to overclock further with the same voltage.

The only thing I would worry about is the pressure getting to high in the hose and it blowing off the compression fitting other than that pure awesomeness!

So, once the large amount of distilled water warms up, how do you cool it off? More water just means it heats up more slowly. You will actually overheat your CPU eventually at full load because the water evaporation and heat transfer to the air over its small surface area is not enough to dissipate the heat your system is creating.

FYI,

It takes 2.47 watt/hours to heat one gallon of water one degree.

If we consider 10C an acceptable water/air delta and you ran your PC for 50% of the time AND you had an assumed 300 watt heat load:

2.47 watt/hours for one degree x 10 degrees / 12 hours = 2.06 watts per gallon.

If you had 300 watts, you would need 300/2.06 = 145 gallons (assuming you remove the heat just as fast during the remaining 12 hours).

But that's assuming you would remove the heat equally as fast as you added it and I don't think having a tank of 145 gallons sitting there would cut it.

The only way I could see utilizing water's specific heat capacity in that form is some sort of remote shed with a car radiator that operates continuously and remotely...but you've still got to have a means to remove the heat...somehow.

Putting the rad in a river or in a cold well recirculation of some sort...maybe...but nothing practical.

All you can really do is play with a bucket of water and ice short term... I've also seen someone do this with AC unit that cooled a large tank that held the radiator.

I was worried about that too, but the pump has very little pressure (4.6 Foot Head Lift). And the vinyl tube is rated for 70 psi max. Thanks for the comments!
