Loop drawing in air

mattyc123 · 14 Jan 2020 at 09:23

Hello all,

I have recently built a loop using some of my old and spare parts as part of a new PC for my wife.

The loop is drawing in air from the reservoir, it is a a bitspower 525 bay reservoir.

looking at the instructions it seems like i am missing a BP-CBWP-C67 fitting like below.

Does anyone have one of these in their parts bin or have a suggestion on how i can stop the air being drawn through the loop.
My alternative is to buy an internal tube for an EK reservoir and modify it

There isn't much in the loop so the flow is quite fast.
this is the reservoir, https://www.overclockers.co.uk/bitspower-bay-reservoir-5-25-zoll-pom-version-black-wc-308-bp.html
Within the reservoir the outlet is quite close to the surface of the water so (not that I can see it is filling the coolant with micro bubbles) it is creating a vortex up to the surface that it then drawing in air. There seems to be a dynamic element too where the water level drops near the outlet
A bit like this,

I have a ddc pump and it doesn't have any control for speed, I am considering making a voltage regulator to drop the speed of the pump.

Back when I had a XSPC res similar to the Bitspower it had a plastic piece that fit inside as 'anti-vortex' to stop that happening.

this anti vortex component is the part I am missing.

The reservoir is as full as I can get it because the fill port is recessed into the top making it basically impossible to get rid of all the air.
I am in the process of moving house so i cant access my 3D printer otherwise I would print something alternatively when I get my lathe out of storage I could turn something up.

I haven't found any foam, I have packed most of my spares. I think it is limited in space around the outlet so I am not sure if I can fit anything in. I did find some of those fittings but they are US stock so long shipping time and costly. When I find the foam I will try it. I am going to look into making a speed regular for the pump too.
