Any idea,s how long this takes?

cant seem to get the last little bubbles out :confused:

do you have to sit there with res top of till all out? alpha cool 120.3 system with Ek water block and res/pump at highest point of system!

cheers

Is it the Alphacool DDC pump with the reservoir directly on top? If it is then the bubbles are a 'feature' and you can either put a piece of soft foam/sponge in the reservoir to stop the swirling or you can 7V mod the pump so it pumps more slowly. That's not the greatest piece of kit in the world frankly.

Yes its that pump! so if i buy a new pump and res this will be sorted?

New i should have bought all separate what pump and res the best?

cheers

Don't change the pump, it is one of - if not the best around at present.

Unbolt the res top and use a seperate res or a t-line.

Any of these will do the job, though the Swiftech and EK ones are very good.

Yes basicly

They will dissapate over hours , perfectly normal. Give the tubing a flick every now and then to help move them on to the reservoir.

If they are pin head bubbles then turn your system on an use it as normal , the heat will help get rid of them.

But , If there is a constant supply of new small bubbles , check you tubing connections as air might be entering via the joints.

Nothing wrong with the pump.

There is nothing wrong with the pump bit but the combination of that pump and that reservoir isn't great. The bubbles are caused by the water swirling inside the reservoir and air is sucked down a vortex into the pump again, which makes the whole thing very noisy. All you need to do is get a small piece of bath or car-washing sponge and put it in the reservoir. That holds the water in a way it can still enter the pump but it doesn't swirl anymore.

Or you can 7V the pump so it pumps less fast and the water returns less quickly to the reservour, which has the same effect - no swirling.

I never suggested changing the pump or the reservoir. You don't need to buy anything else.
