Annoying Pump Noises

[TomH]

So I have a sort of custom-aio in an itx build and due to the size constraints, I have the pump/cpu block at the top of my loop (I know I shouldn't ).

Since it's at the top, it tends to get little air bubbles stirring around which causes an annoying vibration in the pump. I'm sure it's probably not good for it either.

 

I've attached a little diagram of what's going on behind the gpu using my amazing paint skills.

 

I have a small 45-degree fitting (blue) coming off the top of the pump (red) to act as a tiny reservoir, but it wasn't as great of a solution as it was on paper.

I was wondering, is there anything I could do to stop the annoying noise (aside from re-doing the loop completely)?

Thanks

Pump is highest thing in the loop which is why you can hear it and why its going to die soon.

 

You dont have many options in that case unless you can move the pump

just cause its making sounds does not mean its dying... my pump makes sounds all the time like dripping sounds and swishing 

thats completey normal and just cause it is in that postion doesn't mean its gonna hurt it cause it won't... its just a noise issue not a it could die issue

The air bubbles will shorten its lifespan considerably

so thats like saying if you don't have a bracket under a heavy gpu it will shorten its lifespan due to pcb flex

ya it may happen way down the line but by the time it does become a problem the user will most likely have a new build or entirely different cooler

It's definitely not ideal. Might it be a good idea for me -- since it's essentially a custom aio -- to take the whole loop out, fill it up as full as possible outside the case, then install it back again?

it would be a great idea... but its not gonna be the end of the world unless you notice your temps rising horriably or something in that matter i wouldn't worry abou it

If one of your tubes is long enough, try getting it behind the GPU and moving up before curving back down into the radiator. That way air should be able to gather above the pump. Thing with water cooling is, that you should have the pump always flooded. Your case does restrict placement though so my only suggestion would be a bit of case modding by adding a tiny reservoir on the back of your case (on the outside). Makes refilling and draining the loop a lot easier later on as well.

How about using the PC on the side, not on the feet?

There is a port on the top that I was using for the 45-degree fitting. Could I have the tube go up and through that port, then back down through the pump and out of the bottom of it?

[TomH]

It is supposed to just be a fill port so it might not be suitable:

Yeah that could work. The important thing is, that there is plenty of water above the pump.

Well than you will have to redo the loop.
