Bubbles in my loop - Is this a problem? [video] - Page 3

post #21 of 30
I would open your res to let the air out and put a paper clip in your PS go Green to Black and just power on your pump for 10 seconds and power it off about 30 times. Then let it run overnight with the cap open. Then power it on and off for 10 seconds after your 8 hour run, should be good to go.

That could be an issue; my pump was vibrating a lot and there was bubbles from block to rad only; rad to res was clear, res to pump too; pump to block was clear.
Maybe it's a block thing too; makes some spirals or something.

Have you used any additives to the water? Something with a mild detergent might cut the water tension and help the air sepreate better. Otherwise, the vortex air bubble chain looks kind of cool.

I had to leave mine off for over 24hours to get all air out of my system, I don't know how else the air will leave.
the air doesnt have to leave if the loop is sealed then the water in the res will take the place of the air bubble and the res level will just drop...

Im no water cooling expert... In fact I know almost nothing about it but.... I think the bubble stream looks really cool!

What sort of coolant are you using? i had the same sort of thing with my koolance gpu block using distilled water and Feser 1 UV dye. Was constantly turbulent in the GPU out creating bubbles that were sucked back into my loop.

Ended up with clogged CPU block after only 2 months from using it so i swapped to distilled+killcoil and havent had any sort of bubbling since.

Try to reduce your pumpspeed, i have the same problem at high flowrates.At 9 Volts this dissapeared,and i haven't lost any cooling performance.

I have to agree with Pascal, high flow rates can cause excess turbulence in your loop creating endless bubbles. After I built my first water cooling system last October I noticed there was some pretty strong turbulence in the top of my reservoir, it produced an endless supply of bubbles, removing the acrylic tubes and installing the anticyclone eliminated the bubbles in my loop. I also noticed that if enough side pressure was applied to my Bitspower 90 degree fittings the rubber o-ring would allow air to be drawn into my loop.

I think it looks cool too! I am just worried if its a sign of a problem.

I am on distilled and kill coil only. No other chemicals.

My pump is powered by molex. Is there a special way to control pump speed? Whew...I thought I didn't have enough pressure and almost bought a dual DDC pump top with another pump!

Thanks for the info. I have a feeling the acrylic tubing is no real help in the reservoir. As soon as any air is pushed through the system, it's immediately fed right back in to the impeller. I'm thinking of getting a different reservoir.

The Res should eventually collect them no?
you would know if it were a air/coolant leak,
that many bubbles would = puddle at the bottom of the case
