Hey guys, haven't asked for help in a while, but now I need some! :D

I'm building a loop & need some advice. I want everyone's opinion whether its negative or positive!!



Here's the configs i came up with

From what I've always been told, you try and make the tubing runs as short as possible, so why not take the radiator orientation from #1 and combine that with #2? That should give you the shortest setup. Also, are you actually running a line from the reservoir to the pump or is that a pump top that can mount a reservoir?

Its a line running to the Pump from the Res

Without knowing what kind of pump you have, it looks like your pump tubing is backwards. You want your res to feed into your pump. Then go to the shortest routes.

I still am unsure of which color is which, but basically you want your res feeding into the top of your D5 (Swifttech pump).

It really doesn't matter very much. Res on intake of the pump and then everything is a wash, just find something neat and that you can maintain. Its ultimately not important to the performance of a loop in any real practical sense.

The tubing in those arrangement are so short that it doesn't take into account that it would kink at that angle. I suggest placing the reservoir and the pump on the same level, with the lower port at the same height as the pump inlet, connected with a short tube. Then add a 90 degree angle in the reservoir inlet which goes straight up to the CPU block outlet. The radiator would have to be aligned similar to your first configuration.

I have some XSPC FLX Premium Grade PVC Tubing which is suppose to be highly flexible for tight bends

I'm pretty sure it will never get you the extreme angles that you've sketched out. Your method would work provided that you're willing to spend a lot on angled fittings while mine would require at most only one 90 degree fitting.

make sure ur pump NEVER has inlet facing down.
Inlet facing up is actually preferred over standard config.

Could you show me a sketch up of what your talking about

Well, I'm too lazy to draw now. Say that you have connected the pump and reservoir like I mentioned earlier. This pair will be placed in a way where the pump is closest to the motherboard tray(near the rubber grommets) and the reservoir facing outwards. This will place the pump outlet inline with the radiator inlet which you could then run a very straight tube up.

The radiator outlet connects to the CPU inlet and the CPU outlet goes back to the reservoir with a 90 degree fitting. Probably another 45 degree fitting at the CPU outlet facing towards the front if you don't want to tie down that section of tubing to the motherboard tray.

Not really seeing what you mean

Only the pump outlet will be facing down if i use any of these configs

that is not good... as u can get a bubble stuck at the top of the impeller chamber and have a moment where the pump can run dry.

the outlet must be facing up with inlet sideways so bubble can escape top.
or sideways with inlet up... so bubble can escape out back though inlet from the top.

Visualize a bubble...they always want to go up, but can be stuck in a chamber or cavity...

can it escape in the config if it was stuck inside the chamber?
Will your pump run dry?

if u can say yes to any of those questions... then the pump is located in the wrong position.


EDIT... the only time u can sort of ignore this is if u have a redundant pump system and your first pump is in a location where it will never run dry.
Then you bleed with the first pump... and then activate the second pump some time after.
You probably dont want to bleed with both pumps on anyhow... as too much flow will just chop up your bubbles and make bleeding longer.

just think of an (L) u see how in a L it points up?
You want something pointing up.... because a bubble likes to go up.

You wanted a (ㄱ) which is bad because u see where the bubble would go up?
It would get stuck at a corner...

oh i see now thanks. ok so i need to figure out a new mounting position
