Since you are using to 1080 radiators, why not make the reservoir SURROUND the radiators and take up the the majority of the front of your desks legs? You could then back light the whole thing and have water "glow" and see light come through a little on the radiator and fans.




You could do this on just one "leg" (either the front and back, or front and side, or side and side) or do the fronts on both "legs" (ie the cubes you already have) and just have mesh on the back side to allow for air to escape from the back from the fans on the 1080 radiator.

So if I'm understanding this right, take this:



and remove the plywood face of the radiator and replace it with a reservoir? that's pretty awesome looking I have to admit. That's a hell of a lot of area to get water tight seals on though. Maybe doing 3 or 4 seperate chambers would make it work?

Exactly.

Yeah it would be a large seem, but it would be an over the top thing that I've never seen done before.

Either that, or maybe make a long "back splash" that goes along the entire top length of the desk ... if your desk is 5 wood wide, maybe make it 5 foot long by 6 inches high by 2-3 inches deep. That too would be big, but if you filled it with fluid that would "glow", that would look wild.

Maybe even just 2 panels that sit on the back top part of the desk that are like 18" by 18" by 2" thick and have some internal shelves at a 45 degree angle to give a "water fall effect" (fill it from the top, let the water flow down like a Pechinko machine to the bottom, then into the radiator. One on each side of your monitor. Again, with a UV light and fluid, that would stand out massively.

If i had the money i would get a HAF Stacker and make the whole 915r placed on the bottom the resevoir, with some submersible pumps. smile.gif

Well, you could always use a stock 10 gallon fish aquarium (or larger) and go with a a submersible pump. Maybe even one that is a cylinder or hexagon shape.

While not a desk, I had a really warped idea ... like a 20 gallon fish tank, then make an acrylic box that would be suspended in the middle of the tank. Inside that you could build the PC and put the electronics in the newly built box then set the box in tank then fill the fish tank. Basically, your computer would stay dry and could be accessed from the top, and water would surround it on all 4 sides and below.

Hmmm

It's a bit late, and I'm a good 10 years removed from the last time I legitimately used physics to solve engineering problems on a regular basis, but I'd wager it has to do with maintaining a proper rate of flow. Like if you had 5 ft of tubing all at .5 inches in diameter it would house 11.78 cubic inches of water, while a section of tubing 5 ft long with a diameter of .39 inches you would only house 6.8 cubic inches of water. That would mean you would need close to 70% more output from your pump in order to get all the water to make a single revolution in your loop. I'd wager it has something to do with maximum thermal displacement return on minimal workload from the pump. Of course there is a lot more factoring into it, but that's the basics. You should contact EK or Swiftech or something on that subject, I'm sure there is a lot more I'm forgetting. I hated fluid dynamics in college and have used exactly none of it since I left the class room.

That being said, the reservoir is the end of the line, so as long as it's not smaller, or more restrictive, than the most restrictive part of your loop (which most water blocks and radiators are using the 1/4th fittings standard anyway) it means nothing at all aside from how far you want it to squirt out (just like a hose with your thumb on top of it).

And ofcourse, I'm very glad you brought this to my attention, I'll probably use a different fitting for whatever I end up making here since the threading on the Bitspower compression fittings are so short it will be tough to get a good, water tight bite with less than perfect tapping.


Question, is there any valid reason not to just get a 3D printer and use that to make my reservoir with? Would give me an excuse to get one maybe.

In a word, no. A pump doesn't "know" how much water is moving. All it "sees" is the restriction to the flow it is trying to produce. Pump a pint, pump an ocean, it doesn't matter to the pump. A pump just creats a pressure differential between it's inlet and outlet. The more flow restriction there is in the "loop" the less that pressure differential will be, and hence the less water the pump will move per unit of time, less liters/minute.

All pumps (and fans too, for that matter) have a P-Q curve that relates how much water (or air) they will move related to the pressure (restriction) they have to overcome.

Martin's Lliquid Lab Pump Planning Guide
P-Q Curve




As for a 3D printing, that would be a question for a 3D printing forum or printer manufacturer.

You should make a reservoir that looks like a sandwich on top of your computer.

Edit: with all the fixings.

And some other watercooling stuff:

Gravity (and hence component placement) has no effect in watercooling loop.
What you loose to gravity on the way up, you gain back on the way down.

Flow rate has no effect on the amount of heat removed.
In a watercooling loop the water spends exactly the same amount of time in each component over a finite length of time no matter what the flow rate is.
Halve the flow rate and the water spends twice the time in each component, but it only goes through each component half as many times.
Double the flow rate and the water spends half as much time in each component, but it only goes through each component twice as many times.
The benefit of higher flow rates, and it is a big benefit, is increased turbulence (and hence less laminar flow) in the heat exchange components.
