Hello, guys,

I have a water cooling system with large radiator, DDC 3.2 PWM Elite, ASUS C6H monoblock and an Aquatube as reservoir.
Unfortunately there are several air bubbles in the monobloc and I just can't get them out.
Do you have any tips?

Regards Stephan


After the pump it goes directly into the monoblock, then further through the radiator (above the case)to the resrvoir (before the radiator in the upper right) from the reservoir back to the pump.

Hi,
You have soft fluid lines so it's actually pretty easy
Just squeeze the inlet and outlet lines to the mono block (not at the same time)
That will create enough push pressure when you release to push the bubbles along with the flow

I had hundreds release doing that repeatedly

Also setting the pump at maximum speed helps moving bubbles

Hi,
You might actually have to flip the machine upside down or opposite of where the bubbles are and squeeze the hoses a little :/
It can be a pain it's sort of a backwash area without much push
I had these 2 small ones and finally got rid of them doing the above

I only have these two little ones left.
Try again as recommended. It's not that easy, the damn thing is heavy as hell.

I have ordered a new reservoir (EK-RES X3 250 RGB).
If it is there, I'll make everything new...

Anything I should take care of when filling?

The main thing to do is to tilt or move the case around. Maybe try filling it with the case on its side, such that the monoblock is facing up, so that the bubbles can exit out of the block without any dead zones.

Hi,
A friend said to remove the mono block and shake it a few times might help
Hard tubing makes that a tad difficult

Soft tubing advantage

what do you mean? do I have to remove the old expansion reservoir from the circuit? Or can I leave two in there?

Hi,
Remove the mono block
Leave the lines connected to it except the rgb disconnect it
Add the test jumper so just the pump is running the fluid around

Shake the mono block every which way till the bubbles escape the backwash area and disappear.
Or just leave them there they won't hurt anything.

I think he means to unscrew the block while still connected to the loop and shake it around while the pump is running and the rest of the computer is off.

Hi,
Indeed 24hr leak testing environment just as the manual describes you'd just be doing it to get rid of the bubbles
