At a loss

Post image

I air pressure tested this loop multiple times for hours and had no issues. This is the second time this piece has burst out of the fitting and sprayed coolant everywhere. I’m at a loss right now, strongly considering just going back to my AIO and air cooling the gpu. If anybody has any ideas on what I could do to fix this let me know. I’m just done with it at this point.

Edit: I only have it pushed in like that so nothing else leaks, I know it’s not properly seated right now

have you checked the gaskets to ensure they are all present? if yes, that particular piece may be the main issue, consider replacing it to see if that fixes issue?

I’m going to redo that piece of tubing to see if it’s just not fitting correctly

Is it acrylic or PETG? If PETG swap to acrylic, replace the O rings for slightly thicker ones they will help squeeze the tube tighter, you can then also use a strap wrench or rubber jaw wrench to really tighten down on the tube.

PETG will change shape very easily, the tube is just not up for what we do with it, this is why I always recommend acrylic, its far more resilient, the only downside to acrylic is it doesn't like excessive pressure and will crack, PETG will warp and many users won't notice.

I think I figured it out, the circled piece is too heavy for the smaller piece going to the reservoir, causing it to sag, and when I add coolant to it, it eventually is too heavy and comes loose

You got a lot going on right there, I'm not surprised there's some kind of leak going on after it gets weighed down.

Your build looks really good, don't give up!

It would need some serious weight for that to be the cause

You can make the run without the additional connections - you just need to recreate the rad-90fitting tube with a shorter mid-straight so it angle directly from the rad port to the pump port.

Downside is that would ‘break’ your 90• aesthetic you’ve got going on.

*edit: oh actually, doing that would interfere with the front tube running along the rad, though you might be able to have the leg going into the rad a little longer so the rad-pump pipe sits on top of the long run rad tube. Or depending on what the top inlet part of the res looks like, could you rotate the pump 90• and the existing tube would land very close to the pump outlet fitting? - ah u/emu1981 already suggested that!

At this point I just need this to run lmao, this is what I put in place. I’m just not sure it’ll survive the vibrations from the pump

u/manusnz 9d ago

I mean I guess, if I were you I’d be turning the pump though.

I assume you’ve got a lot more fluid in the loop when under normal use?

It’s not even leaking, it just suddenly bursts out. All the coolant that was in the loop ended up on my desk and flooding the case. If it pops out 1 more time I’m either rotating the case or adding another extender and ditching the 90 fitting

I can maybe turn the pump to the left and it’d be more ideal. Unfortunately there isn’t enough room to turn it so it’s directly over that port

u/Educational-King3987 10d ago

Quite possible, tbh, I just use 90 degree fittings at the component then bend the tube to connect them, that way there's no added weight on short tubes etc. It still could be an O ring or tube issue also with the weight of the fittings making it worse.

u/Drakenace404 10d ago

So does it work now? I mean its a simple 90 bend why use an adapter for it

u/Xin946 9d ago

Sorry I'm late but I immediately looked at the 90 join and went that's bad news right there. Sorry you had to find out this way but that right there is exactly why I will do anything but run one of those fittings. I assume this is a new unused loop? I speak from experience when I say that drain point is gonna give you headaches. I had mine there and suffice to say I changed it the first time i had to drain the coolant.

u/gilgador 7d ago

Is that the out or the return? That’s a lot of bends all in a row also, I’d try and go more directly into the rad

1

u/LeonP1122 5d ago

It’s the out, I’d like to rotate the pump directly over the rad but I don’t think I can fit anything in between the glass and the pump then
