you should be able to pull the impeller out completely.  should only be held by magnetism.

Thanks!  we inspire you to try it out

The bong vents cool air from the outside, and blows the warmer moist air outside.  This works fine for now while the weather is still cool.  During the summer months, the intake ducts will be removed and the air will be cool air conditioned interior air, and still vented moist air outside. 

And yes, that is not a bad idea to re-use that water.  It is essentially distilled water right?   ;)

yea, but this takes almost NO power to run ;)  I am sure the wife would much rather the electric bill be from a water pump then a 1HP compressor

Welcome to the forums!

Man thats awsome cade great work

excellent, excellent, EXCELLENT work!!

you make ghetto look GOOD too!!

if it is too fine, it will end up blowing out of the pipe.  The water needs to be in droplet form.  Plus it would would probably put lots of pressure on the pump(s)? 

Speculation of course

Glad the BR gods have smiled down upon you.  Let me know if that mister works, I'll try anything.

You should write your list of things that don't work.

I know that I am happy with the tower all together.  It is superior to traditional ambient radiator cooling, at the cost of constant refilling. 

I could write up a list of the pro's and con's if I felt so inclined to do so. 

Excellent idea you have going. I have not read every page so maybe an idea I have has already been tried. Has been an excellent read so far though.

I was thinking about using some sprinkler heads. You can get them that spray 360 degrees and will flow at 1-2 gallons a minute. THis should not load up your pump to much especially if you can place more than one. You can get just the heads and an adapter pretty cheap to screw into 1/2 npt. THis will give you a very good atomization and cool well. Also have you considered using a metal pipe of some sort? Using a metal pipe would turn the whole column into a giant heatsink so any water that misted to the sides will be cooled as it runs down the length of pipe. I was debating trying a similar idea before I saw this thread but instead was going to make more of a heat exchanger. Basically taking a length of pipe like you have and running a coil of copper pipe down the middle. Then flowing the coolant for the computer through that and circulating water down the pipe from the top. This would keep the cooling circuit closed and eliminate contamination and but also achieve good cooling. With the latter you could add a few sprayers at different heights to put more water on the coil of pipes. As far as sub ambeint temps you won't be able to achieve that through just evaporation alone. You would need some sort of phase help but you could get it to ambient.

From what your wife posted I guess you were using some window shakers before and to get sub ambient you would need to utuilize one again. I think if you could submerge the evaporator coil in the bottom tub and get the water down to a fairly low temp then you could keep your whole system very cold bordering on needing to insulate the board from condensation.

Interesting project to be sure keep up the good work with it.

Really like to cpu block you made I have been pondering schemes on how to make one cheaply and I think something like that would work well.

Gilda... welcome to the forums!! We bongers are privileged to have your first post in the forums!!

+1 !!!
It's fun to experiment with this stuff and like Nate said post up some pics of whatever you try. Welcome!

Yeah something like sprinkler heads might do better but not directional enough I imagine, at least for pvc since it won't act like a heatsink. I am gonna change my res tonight and have a much shorter connection to the pump, hoping to solve an issue with flow gradually slowing down. I will post some pics if it proves worthy of such.

Wow, thanks Fiius for taking the time to check these things out. VERY helpful info there! Much appreciated!

Even if you got a Schedule 10 walled pipe, once you get to above a 3" diameter, the pipe gets freakin heavy.  See link for weight per foot of pipe.
What pipe diameter are you guys using for your bong coolers?

I would say it isnt worth the added cost and weight to go metal over PVC pipe.  The more important thing, I would think, would be airflow and getting smaller droplets of water.

Hi Nate,
Nice cooling mod. I gotta give you props on creative cooling as this thread has been an interesting read. My question is, is the upright length of pipe made out of PVC? And has anyone tried swapping it with a very thin walled metallic pipe?

Inside your house, metal is much cooler to the touch than a plastic is. Hence, in this case, a metallic chamber has a better potential of lowering the water temperature coming out of the bottom of the stack. Perhaps the difference would be marginal, but the ultimate goal here is to reduce the water temps as much as possible. 
 
If this has been tried and tested before, kindly dismiss my perspective on this theory. Keep the overclocking spirit alive guys! :)

We have tossed the idea around but no one has tried a before and after.  I can't take credit for the initial idea, they have been floating around on various forums for years.  I like the metal idea, and my shower head  gets ALL the water down the sides of the PVC pipe.  I just haven't thought too much about changing it (yet)
