I was looking for some input on this design before I start trying to build it later this week.

This would be made out of 1/4" plexi with 1/2" tubing.
The gold parts are the barbs
green tube (1" ID from us plastics) is a clear hollow tube to allow the 1/2" tubing thru the res.

The case is 18" deep X 7.5" wide x 7.5" high.
The res part is 3" deep x 7.5" wide x 7.5" high for a volume of about .72 gallons if I did the calc right.

Formula:
hight*width*deepth*.0043=volume in gallons

I kinda have to make the cuts on the plexi glass easy since this is being cut at home depot for me.

Also I'm not sure if I will be placing this on under my case or on top. But it should be able to hold up either way.

Any thoughts or suggestions?
 
ouch @ 3d image.

If possible to keep noise down, try to mount the fan inside the case and add sound dampening fluffy stuff.. It can be more quiet then your monitor if done well.
 
Ditto on the airflow question. You going to put vents on the side?

How are you going to handle the electrical aspects? Will you install a power socket and switch for the pump? Where? Will you have RPM control over the fan?

Seems to be a good setup so far. The only mild grumble I have is with the pump outlet. Looks like you've got a 90-degree angle there, or is that just something the rendering software does?

We see where the components are going to go, but what actual brands have you selected?
 
This is my design:

Two 120 mm intakes at the buttom then goes out on top pulling air thru the rad. Planning on making a 120mm hole at the back but it will disturb the flow of the buttom intakes maybe 2 80mm with duct at the front.

The red switch is for turning the WC psu on and a temp monitor in the 5" bay the middle part is for a 3.5 fan controller (I'm gonna make my own in-line temp I have the tee barb but don't know how/what to fill in the to part with bondo maybe??).

This is how it will look like in that box.
I'm just confused about your design coz I didn't see any holes for fans. I saw other two guys who did an external box in the coolcases forum. just browse thru it they've got their own design too. And cut your arylic with laser looks better mine is cut on a table saw. And the psu will be mounted on a box at the back of the wc box.
 
I am thinking of doing something similar, but had a question about the power.

Should I bastardize a power supply and include it in this to power the fans/leds/digidoc (or whatever), then splice (for lack of a better word) the pump's cord to run off the AC as well.

Or is there something I can do to power the fans & stuff off of AC.
 
Here is a ]rough mockup of what I am thinking about doing.

Thoughts?

ps. the radiators would be heatercores, w/ shrouds and 120s
 
Uhmmmm.

I could build a massive watercooling loop/loops for my 20U rack of servers. Got to get this out of the house and into the garage, too much heat. The wheels are turning.

Forget those little girly 12 V fans, I am thinnking nice 110 volt ventilation fans.

If I rig it right, I could use the same fan to draw air out of the rack, uhm.

Thanks for the ideas
 
That was just a rough design that took about 20 mins to design up in autocad.

Questions about airflow:
In front of the rad there will be a big cutout in the plexi case for flow and then on the side of the case there will be vent holes cut. So air flow shouldn't be any problem. Just mainly I didn't feel like doing a subtraction formula last night for the design.

Tubing angles:
More or less the 90 angle was only there becuase I was to lazy to learn how to do a smooth bending pipe last night. Nothing in this system will have a 90 degree turn.

Power:
The power wires to the pump were going to be cut and then solder on to a standard computer power connector. I was also just thinking about getting a slow ac fan that could just tap into the power from the pump.


Its been about 3 years since I have done anything with Autocad so you will have to accuse the shitty models.

I hereby accuse the models sitting before us of shittiness in the first degree!:p

Looks like you've got a good project planned out. Looking forward to seeing the results.
 
So you'll just use one fan right?? And are you going to use a different PSU to power up the WC components or you are just going to connect it to your comps PSU?
Yeh go for it now can't wait to see it:D
 
The water pump is a AC one and I also have a parts catalog at work with tons of AC fans. Just to make it a simply little wiring project. That way I can use a standard power plug for it.


Edit: Looks like I will be using a DC fan after checking the prices of AC fans. So I will probably just rip apart a old 200 watt power supply I have sitting around my apt. Tomorrow I will be going to home depot for the plexi glass.
 
Hmm. I wonder why you don't try side cooling instead of front to rear - This would allow both radiators to have external air access an vent out the other side instead of warmed air from one radiator feeding the second.

You could even have internal ducts to route the air better.

Similar to the Hydrocool, just an additional radiator - and you could probably fit a couple filters as well. Might even be enough room for a third.
 
The amount that the rad will heat up the air is really nothing. Sometimes just follow KISS (keep it simply stupid). Also you may want to add a res in that rough layout for bleeding purposes.
 
You might want to consider using a submersible pump, just for sake of less tubing and crep to deal with.

As far as where to take the cord out, just route it up to the top and have it go outside form there. Plus the water will absorb some of the pump vibrations, which is a good thing.
 
I guess we should talk about which rig we are refering to.

The reason why I don't place the pump in the water is a very simple reason: I prefer not to heat up the water by having my pump in the water plus that would been a good size res if I did. I plan on moving the rig around sometimes and with more water comes more weight.


I aready have a layout drawout in Autocad for the sheet of plexi that home depot will be cutting. I made sure even a idiot could make these simple cuts. shame I have to buy a 48x24 sheet to use instead of something smaller. But it is only 30 dollars for 1/4 inch sheet that size and then I will have left over for other things.
 
Did it using diaper box before :p
Add reservoir. Works quite nicely IMHO. Only thing is the 1/2" tubing behind computer is not the best thing to have around. Some quick connect disconnect will be nice to have :)
(maybe split the 1/2" to multiple smaller ones and go through PCI slot?)
 
Um the only thing thats hard to work with is making the seels perfect and finding the right fittings to curve etx. Get the fittings first then design the box. Or make it in cardboard then design it and lazer cut it. If you look up my post with my design in Solidworks 3D u will see what i mean.
 
One very small change to think about.
Try and use a 3/4" barb between the res and the pump.

Here why

Luck........:D
