Just put it together, Help needed

Ok i just put together my WCing kit inside my Lian Li PC-7B Plus and I have a few questions. The Laing (Swiftech, Dangerden etc) DDC pump is supposed to be quiet right? For some reason mine sounds like an aircraft carrier right now. Is it because theres still air in the system? Does the pump get remarkably quiet agfter 24 hours once all the bubbles are out?

Initially I was using a cheapo 250W PSU and it couldnt even power this pump, the pump was making jerking noises and wouldnt push any water at all. Now im using my main rig's 480w Enermax and its running great, but is still VERY loud. is it OK to run the pump with no fluid inside? I did for about 30 seconds on the first run.....

And last but not least, When i raise my Pump above the 3.5" resevoir, all flow comes to a halt, this is normal right? As of now, I have the res in the 3.5" bay with the RAD about 4" higher than it, and the pump on the base of the case, this is optimal, right?

And last but not least, Will the air bubbles still dissipate even if i closed the loop? IE- No more holes are open, everything is zip tied and plugged.

is it possible that my pump is defective? OR is this all normal....Last time i did WCing i was using a submersible pump so, im not sure here.

help appreciated.

Air in system = loud noises. Did you use any noise isolation techniques to eliminate secondary noise from case vibration? What are you doing to get the bubbles out of the system? You can tilt the case this way and that to help move air pockets out of your system. With my Aquastream pump it can be above the reservoir, but it is more difficult to prime so you have to be more diligent about filling up the system. However, it just sounds like excess air in your system.

You should carefully monitor your DDC for any problems with not starting up correctly as there have been scattered reports of it failing to start unless you tap on the side of the pump case.

Yeah ive heard of those cases, dont worry i hit it with a pair of pliers to make sure

As for insulation, the pump came with 1/4" Black foam under it, and i added three strips of double-sided foam tape from 3M so ide say vibrations will be kept to a minimum, and all my case fans have rubber grommets onthem aswell. Im going to try tilting my case back and fourth right now, We'll see...

Theres still bubbles! Its been almost 6 hours now, and the fluid is like foam for the most part. Im using MCT-5 liquid btw. Theres no liquid at all, its all bubbly foamy stuff. Does it really take 24 whole hours just to see liquid?

Turn your system off for a couple hrs to let the water settle. Then see if you can add more fluid to the res. There's probably a huge air pocket in your rad, so once everything is settled/topped off, rock the case/rad back n forth to try and force the air into the line.

also depending on how your res is set up it the flow through it may not allow air to rise to the top and just keep it flowing within the system

True, hopefully once all the foam settles, there will be a big air pocket in the res, so he can dump another 6oz of coolant in.

IS it possible that the turbulence in my resevoir is causing air to hit the pump and get chopped up? My res is only like 6" form the pump inlet. I have a typhoon res for a single 3.5" bay, and it has a divider about 1/3 the way over, so one bay is 2x the size of the other. The big bay is where the water is coming in, and the little bay is where the water is coming out, should it be the other way around?

Pics of setup?

From what i have had happen i can say that if the water is too turbulant in the res air will be pulled into the loop. i fixed the issue on my system by using 2 return lines into the res.

I fixed the problem a little bit by switching the res inlet line to the bigger half of the res. I think its the MCT-5 fluid that keeps bubbly insid eturbulent blocks and res's. Once the pump is off, the liquid returns to not having a SINGLE bubble in it when the system is OFF. But as soon as i turn it on, the pump and blocks starts chopping it up and it turns bubbly again....weird.

I had that problem before with the D4 pump and a small rez, I normally make my own rez. I made a larger one and the problem went away. Small rez really suck, I'd use a "T" line before I used another under sized rez................
You might beablt to solve the problem by making sure that the rez is completely full and the system is air free before letting it run for long periods of time.
also, even short periods of dry running your pump could damage it, you have to be 100% sure that the pump has water in it before turning it on.

Will these little micro bubbles hurt my temps at all?

How do you do that? I mean putting water into the pump.

When you fill the rez, you should see the water flow to the pump inlet and out the out put, then you know the pump has water and it's safe to start. When first filling a system I only let it run a few seconds at a time til the system is completely full. Then I turn it on to bleed out the air, I do this with a external PSU modded with a on/off switch that only has the 4 pin connectors, I removed the rest and put a old switch between the green and black wires............... Makes things a lot easier that way..........

Cool man, thanx.

Never knew how to do that

IME these pumps will hold onto air until you shut them off. I turn my pump on and off several times to get all of the air out of it. When you turn it off and give it a shake you'll probably see bubbles coming out of the top.

Does it matter which barb on a rad you use as an inlet/outlet?

Nope
