I just ordered one a few minutes ago in reference to my above post. I like testing my fabrication abilities. If I could bring my old ATI Radeon down I could probably keep and aquarium cool.

keep us posted on your project. This could be very helpful to many of us.

Well, it usually ends up in one of several ways:

*It simply works. Usually comes out this way, or close enough

*It is so overbuilt due to the "just in case" mentality and I stop to realize that mass production items were probably better performing in the first place. It actually ends up more expensive than what I am trying to replicate.

*It sits in my shop for years and often gets flipped the bird when I remember it is there. (magnet powered motor is a prime example of that situation - 3 years and running)

There is a one little problem with PC cooling. The heat exchanger is copper or aluminum made. It will poison the shrimp soon or later. Especially in low PH.

Depending on the series, yes.

It really is a moot point as I do not intend to run the habitat water through the PC Radiator anyways.

Just ordered it today for experimenting. Probably one of the most popular WC Radiator setups you can find. This would be what I might call the high tech solution sans true AC system. The low tech system I drew up a few hours ago might actually be just as efficient if I can figure out the housing. I won't make any designs public until I am positive it works. Personally I find it harder to design the low tech side because parts need to be cheap, efficient, and simple to construct. To me the high tech stuff is just a matter of finding something mass produced and adapting it.

Peltier cooling is waste of money,time and power.I have build 6-7 prototipe form $30 to $900 each.Heat releising is grater then cooling .Peltier are'n efiicient-they are for precision.Now I'm runing one chiller in my 72 gal bowfront tank.I can go 30F + or - It is
with 0.05F presizion.Component cost $1200.Ingener -shematic work 3 weeks.PCB bord population $300.Of cource I didn't pay anything because I'm working in company where everything was free.If you are interested I can provide info.Chiller is with 4x16AMP peltiers.Custom aluminium heat exchanger.Cover with nontoxic galvanize paint good for 15years use in salt water.

I third craigslist. I just picked up a 1/4HP for $80 and my buddy found two for $60 a piece. All three work great.

http://www.shine7.com/aquarium/chiller.htm

I am about to do something similar, does aluminum harmful to shrimp?

OR

using this http://www.xoxide.com/usb-beverage-chiller-warmer.html

with this http://www.tomaquarium.com/prod_details.php?cat=29&p=58

and run a series of air tubing around the cooling plate to cool the water that running through the tubing. of course, the "cooler" will be controlled by a DIY temperature controller.

does anyone get my point?

As I stated before but did not get into many details, certain series of aluminum use copper in the alloy. These I would avoid. Certain forms of stainless steel would be a little more expensive but a better choice.

Using air tubing would be rather inefficient, mostly due to the thermal transfer properties of plastic products and what I would consider a very low surface transfer area. Your basic principals are correct, although you are have too many transfer points in that scenario (sink/air/tubing/water) making it less than desirable.

Seriously though, with less than 12V DC @ .5A you can freeze standing water in a very short period of time. I hardly find that inefficient. It is just a matter of experimenting with flow rates vs input power to reach the compromise.
