Whats wrong with this setup ??

post #1 of 20
Thread Starter 
hey,
I have just built my first watercooling setup. I need help because the pump is really loud and I'm not sure if it should sound like that.
But if I press on the pump the sounds reduces a lot but there still is a distracting humming sound.
There seems to be a lot of bubbles in the loop maybe thats reason?
Anyway here are some pictures...
Thanks.

you need to let it bleed (get all the air out) leave the top off you res a few days and it should be OK

Hi.

It looks like there are still a notable amount of air bubbles in the loop.

If that is indeed the case, the sounds that you hear are the air bubbles hitting the impeller of the pump.

You will need to let the loop bled-out for (approx.) 24 hours. Once all the bubbles in the liquid have been purged the pump will stop making the noise.

Yup. That would be the impeller cavitating.

I thought about that yesterday and left it overnight but still no difference. Does the mounting of the pump look ok ?

And also do you think there is any problem with leaving the inlet tube for the reservoir (outlet for rad) that long ? seems like some bubbles pool at the bottom of the curve of that tube.

That means there is air trapped inside the pump, so bleed it, if your still having issues tho, I would recommend sending it back.
post #7 of 20
You do seem to have some excessive lengths of tubing involved, and some of the curvatures may be contributing to the lengthy time of bleeding as it looks to me as though there is still a lot of aeration in the loop.

Another thing that you might try is to re-orient the pump so that the surface that is on the sidewall is against the bottom of the case. The orientation of the impeller might have something to do with the sound that you are hearing.

Additionally, is the pump securely mounted and have you used any anti-vibration pads of any type?

I have that same Jingway pump in one of my builds and if it is not properly isolated from case it will resonate really badly.

The pump is a EK-DCP 4.0 I used to the sticky pad supplied with to try and isolate the pump form the case. Doesn't help much. How did you do yours ?

The watercooling system is not finished yet as you can see, I'm waiting for one more part so I can finally install the CPU waterblock. I will shorten the tubes then, see if that makes a difference.

Is it possible that there is not enough water in the loop ? Beacuse when the case was on its side the water would not reach the pump, and there were areas of the tube where there was no water at all. When the case is upright the reservoir is full. So I cant really top it up I dont think...

thanks.
