I was almost afraid to post picks of the work in progress. I eliminated the balance line. The cavitaition, siphoning, cyclonic action and aeration all ceased at that point. I was enjoyiung the waterfalol effect in the shop...it's a great demo of the low pressure zone at the pump inlet...but as you pointed out air and water do not mix in PC cooling...

This morning I removed the balance line and fitted a short piece of tube onto a barb to allow for the air in the system to perc out. After about an hour a great deal of the air had passed and the snapping crashing and gurgling were gone.

And this is the way loops are with no restriction...if you take a D-5 and simply loop it thourgh a reservoir you are going to see so extreme turbidity. But once a "load" is placed on the dynamic it settles down appreciably.

Here is the way the rig looks installed with Sonex, no balance tube, fans on high, bled out after 5 hours.

BTW what I am compariong this too is in a vid I am uploading: a PA 120.3/ Bonnie Core IwakiRD30 set up. I had 6 Panaflo 86.5CFM fans in Push Pull on the PA120.3 and they were one source of noise. ALso the way I mounted the Iwaki generated some unpleasant noises as well. The described set up ran about 9 months 99% of the time. I only shutdown a couple of times to rework stuff on the rig. It kept my Xeons at arounf 58C underload according to real temp (68C according to COre Temp) and now my hottest core is 48C in Real Temp and my coolest core is 35C. This is with fans on low. Ambient air temp for the rad is 23.9C. That's 25C Delta for 100% load (Folding)

Thaks for the clearification Cyber.

The balance tube is/was an excellent demonstration tool!

Well I was using it to fill the rig. The way I fill an external cooler is through the inlet outlet tubes with the rig on it's face so the rad inlet outlets are pointed to sky.

This way all the air comes out. But I was getting a vapor lock between the reservoirs so I added a balance tube.

I left it one to top off the reservoirs after fitting a Stoprm WB to test the loop. Well that's when I saw the siphoning waterfall..I thought: how cool is that.

So I made several vids of it and then started wondering how come the loop was not bleeding out...heh. I mean you can see the stream of bubbles so it's pretty obvious what's going on.

However with the reservoirs topped off and a barb and tube one one of them it bled out pretty fast...topok about 5 hours to stop having to fill the tube. I have not seen a change in the fluid level fro a couple of hours so whatever air is in there is coming out in tiny bubbles now.

Wow that is some pretty nice work, CyberDruid. :toast:

Is that what you have cooling the Skulltrail Quadfire rig?
