Newbie question, res is full some tubes are not when system is turned off

[Yoshimitsu]

Hey 

 

So finally my first custom water-cooling setup is finished and works as intended.

 

There is one thing I don't quite understand, when the pump is running the reservoir is filled almost to the brink and obviously all the tubes as well because water flows through them.

 

But when I turn the pump off the top 2 tubes stay partially empty and the res stays full.

 

I'll attach a couple of pictures.

 

Is this normal or?

The air goes to the highest point and that's not your res, so yes.

Meaning there is still air that I have to get out of the loop?

[Kilrah]

Ideally yes. But it seems your fill port is on the right and the way it's placed it's going to be hard to convince the air to get out from it. Best is probably to fill from here

Alright thanks I don't know if I can open and close that plug as you can see there is barely any space. I closed those ports before I mounted the radiator.

 

I could try.

 

While I fill into the radiator should I keep the fill port to the right open or closed?

[Kilrah]

I would squeeze the little bit of air that's in it so it goes to the top as well and keep it closed.

 

Yeah it's not clear from the pic if the whole top panel can be removed but it seemed like it might...

I tried to unscrew the plug from the top of the radiator to try and bleed the remaining air. I managed to unscrew the plug but not take it out entirely, would need at least 3 more mm headroom. 

 

Idk if the air can go through anyway. What do you think?

 

Also is it normal that it creates bubbles when turning on the system and shutting it down? 

 

The top tubes still don't fill up entirely but I guess that's normal considering the loop is not 100% filled and always the highest point will stay empty right?

 

Idk how to know if I bled all the air out.

 

I let the loop run yesterday while moving and wiggling the case in different directions until no more bubbles were to be seen. But today I did it again today some bubbles did come out, although the water level did not change.

 

Sorry I am a bit confused.

 

Maybe the best idea would try to mount the radiator as low as possible (I think it should be possible to move him down maybe 2mm). Maybe that gives enough space to use one of these air valves as plug and bleed the air from there.

Would like to hear your thoughts

 

 

Thank you

The air won't leave on its own, there is some and it'll continue circulating because the loop isn't full. Would have to remove that top plug and finish filling from there.

Pretty much have to fill it completely with no room to expand if you want to avoid that issue. Or leave it as it. Assuming you have no way to have the return go in the bottom of the res. Or add an internal return tube to the res.
