Sprinkler instead of rad?

[Wwing49]

Well I have started this project (http://www.ocforums.com/showthread.php?t=401420) and came across the problem of cooling the CPU. I do not want to use a rad in this, but am wondering if I will be forced to? Would the sprinkler and a thin and large surface area res be enough to cool an underclocked 2.4 celly with a WW WB

So you want to build a bong (http://www.ocforums.com/showthread.php?t=321055)? That would work.

Bong cooling is very effective, I ran my first watercooling system without a radiator. The only downside is that it needs to be monitored and refilled with water regularly. Nevermind underclocked, you should be able to overclock that celly ;)

The res would have to be open to the air though. It still probably wouldn't work nearly as well as a tower bong.

Could you not find a way to disguise a radiator to work with your theme? You could make the front of the case look like the front of a firetruck. Real fire trucks have a big front grill with the radiator right behind that. You could do the same with your computer.

The sprinkers would release the heat but where would the heat go. If I understand your basic design (What I think is great) the water would be in a large plex-glass case; problem is the heat would not escape.
Some ideas on mods
The water collector at the bottom of the case. Make an metal tunnel under the water level and air-cool the tunnel. Increasing the surface area of the tunnel on both side would help. Maybe even use Cu on the water side of the tunnel to simulate the flames.
The copper piping on the ouside. Thrermconductify connect the pipes (weld) to a larger lump of metal and put a heatsinking design on the exterior of the case. ie metal ladders with little firemen wearing black with venting holes from inside the case with +ve pressure from inside the case giving air flow.
Use transparent Aluminum not plexiglas. See the late, great James Doohan for formula.

Good luck with your design

Thankyou for your advice, I think I have come up with a solution and I posted it in my project log. Please tell me if it will work. I am going to have air going through the inside of the case and in my mind, cooling the water. Surface area might still be a problem however. This is my Idea http://photos21.flickr.com/29116247_cb51cdfd82_o.jpg

I can't really make out anything on the picture without some labels. What I was thinking, and what you may be dipicting in that picture, is a box, on the side panel. All acrylic, about 2" wide, measuring a good majority of the length and width of the window. At the very top, have a copper pipe with either multiple tiny holes or multiple small spray nozzles. At the bottom would be a pool of water, not too deep, just deep enough to act as a resevoir. Also at the bottom a ducted 120mm fan (designed so that water would not flow into the fan), or two of them, with air vents at the top.

That would simply be a bong, but in a box shape and also integrated into the case. The hardest part would be building the duct for the 120mm fan(s), but if you can build the hole box, the duct shouldn't be a problem.

Sorry about the lack of labeling... It is supposed to be my entire case, the grey blob at the top with the brown tube is the fire sprinkler, the L shaped things on the side are covers for my fan holes, and the top will have exhaust holes with a sheet of acrylic covering them so water doesnt spray out

Dust and evaporation would hold me back from an open air system.
Unless you filtered the air or water dust would collect in the system. Jet or nozzle style WB would be first hit. Sprinkers would be next and whole system after that.
The hot water spray would evaporate quickly, not a problem for a short LAN party or demo. But one too many hours and you could stare your system of water. More water capacity or water tank would be needed to mantain usable volume.
One though is to double loop the system. One water loop sealed and to cool the CPU, GPU, etc. Then another loop for show and lose heat. A second pump and heat exchanger would be the only things needed.
I am sorry to say I am spending too much time thinking about your project.
