Need help in XD3 kit

[Fadiobaji]

Hello, I just finished building the hardline tubes and I installed the all the loop, but I’m a little bit worried because I left the the pump running when the coolant was below the middle of xd3, I thought the coolant should reach the near bottom.

 

Anyway I completed everything but there’s an air bubble in the cpu block and the bubble in the xd3 pump is kind of moving towards the left. Is this normal? Because in the videos I see the xd3 air bubble in the middle while runnuing.

 

Is the drain valve problematic in this build? Should I remove it?

 

And lastly, should I fill the xd3 to the top? Or should empty it a little?

 

Edit: I forgot, should close the fill port or leave it open?

 

Thanks

It's normal for the "bubble" to shift to the left in the XD3. The inlet at the bottom pulls fluid in a counter-clockwise rotation. The vertical ridges are meant to help slow the vortex down, but the pump is powerful and it is still going to be there. If you slow the pump down some more, it will likely center. DO NOT fill the XD3 all the way to the top. Go just above the vertical ridges leaving a small gap at the top.

 

The CPU block flow right to let in your configuration and so it's bubble is slightly shifted that way as well. There just isn't a vortex down below really pulling hard. You can probably get that one out by leaning the case back and letting it go up the left side tube, but you don't have to. It won't cause any harm where it is. You don't want something that exposes the CPU block cooling fins to air, reducing the heat transfer from the cold plate.

 

Drain valve placement is it's own art form. It can be a real challenge in some builds. I might keep an eye on that to see if there is any backpressure from the dead end pushing back (slowing down) the pump exit, but you likely have more than enough power to make it work. No other suggestions there.

Hey, thanks for replying, you were very helpful, what about the fill port, should I close it? Even when testing the loop too?

Do you mean take the drain down pipe off the T-fitting above? Or move the ball valve up to the T-valve?

 

When I was running an XD3 I would use a tube ended syringe to suck out the fluid from the reservoir (until below the in/out ports), then use the those tubes as the drain path. I am not sure that works for hardline, but you could drain most of the radiator that way (syringe out and the top keeps filling it back up). This is a always a hard thing to work in.

I meant the top fill port that I used to fill the xd3. I left it open, should I close it?

Oh, fill port. Still thinking about the drain port.

 

Yeah, you will want to keep that one closed. On some pump/res set-ups it helps to "bleed air out of the loop". I don't find that helps with this one, there is a definite risk of spillage if you decide to tilt it, and more than anything... all that suction makes a lot of noise as air gets pulled in the fill port too.

Thank you very much, you really helped me a lot.

i had one in my cpu block when i built mine, i tilted case so bubble was close to outlet pipe and ran pump couple of times to clear it, also on pump i left it about 1/2 cm from the top so its just above fins, hope this helps, nice looking build by the way
