Laing D5 wery noisy

[grandpatzer]

I recently installed my watercooling setup and I'm typing from it now.

The pump I cut out 3 thin bits of tygon and put as feet, I screwed in the pump to the bottom of case and put 2 thin tygon bits under screws as padding.

There is about 15cm air bubble, It is impossible to bleed unfortunately.

Would this be the reason that the pump is noisy as hell?

You need to turn your rig over a few times to try and force the air out of the loop.

Flip it over so the roof is on the floor and the floor of the case is facing the the ceiling, then flip it again, you may need to do it a few times.

This is impossible as the water comes out though the reservoire.

Or can I bleed it when the fill hole is capped?

So is the high noise because of this?

Will this air damage and make the pump permanently noisy?

Water shouldn't be leaking out of the res, if it is then that means air is getting in. Everything should be sealed.

The air will be causing the noise

Not sure if it will cause damage, I don't think it will. If you leave it running it might eventually get rid of the air but it may take a few days to do it. With everything sealed though you should be able to flip your case which will help force the air out.

lol turn it roof to floor I have never tried that. In most cases (no pun intended) you can just wiggle it side to side like 45degrees as well as front to back. with the system sealed up to avoid spillage. that pump does make a noise when its on the floor i noticed that with mine. But now that its mounted to my rez its ultra quiet. also is urs the vario model?? if so turn it down it might not need to be so fast. I have mine turned down to almost 2 as anything over 3 creates a cyclone in the rez. But with my rz they have a ultra performance oring ( a tad thinner than normal) to increase the pumps performance (flow rate) which I now think I didnt need lol. anywho play around with the speed control (if urs has one) and fine tune it

You never heard about flipping the case over? Tom has mentioned it in a few of his vids.

The pressure will push the air through the loop which will help push the air out.

You don't need to leave it on the roof, just flip it on the roof and then flip strait back over. Air rises so when you turn the case it will be pushed out of the pump and in to the loop and then back round again when you flip it again helping to force the air out.

I will wery soon post pictures how it looks.

I think something is wrong as the pump has wery loud noise, maybe too little padding or air in system.

 

[grandpatzer]

SO I THINK ONLY WAY BLEEDING 100% AIR OUT IS RESERVOIR IN TOP???

So in my case put the rear of case on bottom as first picture?!

When I filled water to RES the other top hole at top of res I used to fill water in system, so I need wery long fill tube to be able to bleed without getting components wet?

Red arrow is where invisible air bubble appears coming up from RES when turn pc off, when PC on I can see tiny bubble in CPU block and reservoire but nowhere else really...

Air in he loop is normal you just have to leave it running and it should eventually get pushed out, filliping the case or doing what S_I_N said will help get it out faster though. For noise dampening for your pump you could get a "shoggy" sandwich, yep thats "shoggy" not soggy.

How does it get pushed out as it is sealed system? as you can see there is only one tube from top of reservoire, the other hole is for filling which is now sealed so no air can get out of it.

Does the air go out though pump?

 

[S_I_N]

its kinda hard to tell from the pics there to small try using like photobucket it'll down size them to forums specs but make them clickable so we can enlarge to see better. from what I can see you have the water returning to the rez in the top of the rez I dont see the fill line in those pics. But normally that top port is for the filling of it this may be why the air is trapped inside. so please if ya can give us a few better pics so we can help you sort it out. Its 7:30 am here where i'm at I have to jet out for a couple hours but I'll be happy to help when I get back.

Thanks for all the help it really means alot

I was finally able to post a picture and show better, so the green arrow is the hole I used to fill reservoir with water, I put a 50cm tygon tube with fittin on to the fill hole with funnel and put in destilled water, once the water no longer went into the res but instead into the tube I took reservoir outside case and took out fill tube so that the water not go inside case.

Then I put cap back on so it is now sealed.



Edit--> Also one of the pump tubing is hitting the bottom card, when I slightly lift off the tube so it does not hit card the bottom card slightly sinks so the tube is pressing it little upwards, maybe this is making the noise on pump?

 

[S_I_N]

ur basic prob is that tube in the top, the air is going to go to the least restrictive path and since ur pouring in the other hole it has more resistance. I'd suggest making the return from the block in the bottom as well or try and take the pump rez out and make it higher than the blocks while you bleed it. air will always go to the top as its lighter than water.

So I have 2 options:

1: So basicaly when bleeding I must have pump and reservoir higher than other watercomponents?

To achieve that I would put case on rear so the res is highest and pump 2nd highest.

One problem that might be big is the fact that the pump inlet is not supposed to point towards bottom according Laing manual.

2. I take res outside case put a water bucket below in remove cpu block tube to it, put a longer tube and install in the bottom of reservoir.

Here is a picture of complete system sealed (fillport on res capped)

not necessarily it helps but alot have the rez lower the issue you have is the return is at the highest point making it hard to bleed out that air pocket.

this is what i would do this way your air pocket will be in the rez where its of no danger

So you are 100% certain having the cpu - tube - res tubing at bottom inlet to res will destroy that air pocket?

on the picture the pump pushes water to rad - cpu - res - pump.

weird thing is that once I shut off PC is when the air pocket appears and it goes from reservoir to cpu suggesting it is trapped in res?!

 

[S_I_N]

yeah it just cant get out. You can try running it over night or longer and see if it works its way out. It should over time. took my current loop 2 days before I finally got the last pocket out. Twisting and turning it helps alot as well. But my case the 932 is heavy empty lol filled with all the gear its heavier plus where i filled it at (my kitchen) I dont have alot of open counter space (cabinets above tall case you get the pic lol) to move it side to side front to back and so forth my sniper case which was shorter was easier to maneuver. also if ur pump is the variable speed model try adjusting flow to push it thru. Its not just going to come spitting out and blammo you got it. It'll take time and patience.

With mine I'd hear a cavitation type sound every so often and would look up and see bubbles (tiny ones) flowing thru and then all of a sudden no more sounds. I also noticed a whirlpool type swirl in my rez and was like ok maybe pumps pumping to fast lol so i turned it down. I'm running it just under 3

thanks mate, will do this.

So my understanding is that the fillport on reservoir should be sealed during bleeding?!

I'm still unsure how air can get out of a sealed system.

 

[S_I_N]

actually mate looking at ur pic again I dont see how it will ever get out. as there is no place for it to go the rez is plumb full now if you put a fitting and tubing on that second port on top and made said tubing higher than the cpu block where its getting stuck on shutdown. It should get out. But ur best method will imho move that return line to the bottom leave about 1 inch of air space in the top of the rez and let het bleed (twisting and turning along the way and i bet that space gets a lil bigger as the air bleeds out.

wish I lived close to ya I'd just have ya bring it over and I'd get it sorted out for ya. its just simply physics and pressure fighting you.

How hard would it be to mount the rez higher in the case??

Ok I will do this, I tried to bleed it using the other top hole with a long tygon tube with funnel it can go higher then the radiator even, however the air never got out, this was with the return going also to the other top hole on res.

So now I will do same thing but return is on side bottom cpu to res, also I might have to change pumpt - res tubing aswell as it's so short so twisting and turning the res is wery impossible.
