Closed Loops, how would I do this??

[perfection]

Last time I tried to make a closed loop with a Swiftech Apogee, Swiftech MCP350 and a MCR220, I killed the MPC350 because it was hard to keep a consistant rate of water flowing into the pump and it ran dry on and off and died.

I hope this picture explains what i'm trying to do.

Components are:

Swiftech Apogee
EK FC8800GTS
Swiftech MCR220
Laing D5 Vario.

The Rad is going to be placed in the top of the case and that's not changing.

So far, the best placement and the only place it'd fit is up in the top drive bays.

I'll use one elbow on the MCR220 coming from the D5, I'm prepared to loose a bit of flow with this.

How would I fill up the loop? what's the best way of filling up closed loops?

You need a fill line, or a reservoir.

the problem is that I can't fit a res or T-Line without taking up anymore space.

I don't think there is really a way that you can do a "closed loop". I may be mistaken, but I've never seen it before.


Anyways an easy way to make a T line that doesn't take much space at all is just do like this

Put a T a little before the pump and put a small fillport there. It doesn't have to be too large, but enough for the air to get out of the loop and some extra liquid.

If you can NOT fit it in there at all... maybe put it before the cpu block, but filling and making sure the pump has liquid / leak testing to get air bubbles out is going to be a B**(Dancing Bannanas).


Danger Den "isn't the best flowing" but this is basically what you will need...

Looks to me like there's room for a microres.

How much space is up there where you have the pump positioned?

[perfection]

the pump basically takes up 2 and a half drive bays.

The Micro Res would fit but there's no way of plumbing it.

Maybe a very short T-Line may fit.

Still, it'd be great if anybody has tips on building closed loops

only way I can see it happening is if the radiator had a fillport or bleedport aka like the Swiftech rad/res or TC radiators.

[GrimReaperGuy]

You cannot do a 'closed loop' in your concept of the term. You need a way to input fluid and bleed trapped air.
As silverphoenix suggested, if you are truly strapped for space (although I don't see why you can't have a T-line above your D5, it would hurt flow, but would make a workable loop), you should look at investing in a radiator with a fill/bleed port.

Its very easy to do if you setup your loop inside your case for tubing lengths etc and then take it all out assembled. Then fill your sink with water and submergea waterblock and unhook one of the barbs and turn on the pump. Once the air is bled out just reconnect the tube to the waterblock while its still submerged and let dry.

I used to run a closed loop when I used a mag3 pump. Fairly easy to just submerge the pump and fill it that way. Its too bad that the DDC and D5 pumps arent submergable.

What jimmer said, I did that when I had a complete second-hand loop minus the MCres which was lost in a tragic isopropyl cleaning tragedy.

[Grafton]

technically even with a fillport you have a closed loop

[Fujimitsu]

only way I can see it happening is if the radiator had a fillport or bleedport aka like the Swiftech rad/res or TC radiators.

This would be a decent idea.

Only other choice would be to fill/bleed it externally and then assemble it... which will most likely leave you with a few bubbles that will never go away.

I can build the loop outside of the case and then install it inside.

So T-Line's are the way to go then huh?

[NaeKuh]

Ram the pump output directly onto the radiators input so you can conserve tubing and avoid that bend your going to have.

Heres an example with a DDC-3.2

i was thinking of that naekuh, just unsure if it'll fit
