Anyone in the Orlando Area?

[Cutless009]

Anyone in the orlando area that can come help me figure out why my loop wont bleed? Id be more than happy to compensate you for your gas and maybe throw in a few beers for your effort. I just cannot figure this out for the life of me, and my back doesnt let me stay upfor very long at a time.

[Gazmtk]

have you tried compressing the tubing just before the Res, to help calm the Res for the air to float to the top?

[Baleful]

Well it's about a 10 hour drive from my house to Orlando so I don't think you would want to pay for that gas.

Do you have a camera? If so take some pics man and I'm sure I can help you.

[zlojack]

Obviously with your back you won't be able to move the rig around. I think having the res below the mobo will contribute to that. It took several days for my two loops to fully bleed on "Good Things"

[Cutless009]

well the only problem is, its not bleeding, at all. If I let it run, after about 5 minutes the cpu reaches ~80c and I have to shut it down, so I cant even leave it bleeding at this point. Ive tried compressing the tubing after the pump and that didnt help, I tried blowing into the fill port, that didnt help. Theres a huge air bubble in the EK Supreme that I can see, but i cant get rid of it, not even by tilting the system. Im so confused

[zlojack]

That's strange. Is the impingement plate blocked? Is the water moving around the loop?

You might have to dismount the Supreme and move it around and shake it a bit.

[Baleful]

Woah hold on, you're trying to bleed the loop with your system running? Don't do that lol. Get a seperate $15 junk PSU, trip it, and bleed the system that way. You'll fry something trying to bleed it with the system running.

Oh, i didn't know that.......i've been doing it that way for years :eek:

Is the water circulating the loops ie. when the system is running, can you see turbulence in the reservoirs???

[zlojack]

I did a leaktest/bleed overnight with the PSU jumped, but after that, I ran it and it still bled a bit and I just topped up the res as needed until it stopped.

Of course, now I drained the bastard again, so I'll have to start all over.

[Cutless009]

only in the GPU loop res, in the other res, a bubble forms on top of the impeller and the water goes nowhere :(

Hehe, guess I should have been more clear.

If you have the system filled and you're trying to bleed pretty much micro bubbles, that's fine.

If you're trying to fill the system and bleed it, which sounds like what Cutless is doing, that can lead to some dead hardware.

After looking at your buildlog Cutless, one of the problems could be that you have your res/pump at the bottom. It looks like it's having trouble getting water all the way to the top of that big ass case you got lol.

[zlojack]

Cutless, aren't you on pretty serious meds right now?

Maybe you should shut it down for a while until your head is clearer and you can attack the problem coherently.

[Mankz]

I've allways either used a paper-clip to short the 24-pin connection, or used one of these:

Just make sure you've got some fans etc hooked up so there is a high enough power draw for the PSU to work properly...

[coolmiester]

The pump position is fine as the DDC has plenty head to get water to the top.

Sounds like the pump isn't bled properly or the impellor is jammed somehow when filling the XSPC Res top or worse still the pump could be bust!

Another reason i hate that black hose as you can't tell where the water actually is............when you first started bleeding i presume you saw liquid returning to the res otherwise it could be the water has just filled the outlet and hasn't started to return yet??

Just to clarrify, the GPU loop is working and the CPU isn't??

[Xilikon]

I agree with others, lay off for a bit until your mind is clearer.

To bleed with the XSPC reservoir top, you need to do short bursts with the pump to avoid airlocks. I see that all the time with my 2 res top and I always managed to fix that with 2-5 seconds running and stop (when it stop, bubbles tend to move away by itself clearing the path to the impeller).

Paul, I'm always bleeding with black tubing and I always manage since the part I'm interested the most is the reservoir. As long as there is no real water movement, I stop the pump and shake a bit till there is a regular movement with micro bubbles then let it run for 1-2 days until fully bled.

[Cutless009]

yah the gpu loop is fine, but the cpu loop isnt. Theres like no flow at all, no micro bubbles, no nothin. When I first turn it on, a big burp of air comes out of the inlet tube in the XSPC res top, and then after that nothing else moves. Theres a big bubble in the EK block that just sits there. Its really obvious that the pump isnt moving water, which makes no sense because its surrounded by water :-/

don't let the pump run for 5 mins, run it for 5 seconds only. That's why you must use a spare psu to do the bleeding without having the system running.

[Cutless009]

Ive done this like 25 times, Im afraid Im going to wear out the pump by turning it on and off repeatedly, surely it has a limit to how many times it can start up?

If the bubble stay there, tilt the case until it move out of the way...

[Cutless009]

Ive tilted it till its on its side in every direction, hell Ive done everything except turn the damn thing upside down!

Then drain a bit and refill...

[Snyxxx]

Give the pump some "love" taps with your hand to get it going. I have seen this myself with my DDCs during initial fill/bleeding. Make sure the res is topped off with water and keep thumping the pump and turning off/on.

I agree with the airlock scenario.

[coolmiester]

First of all, you need to determine whether the pump is actually running when you turn the system on.

With all them fans running it will be pretty hard to hear so try starting the system while touching the pump base and you should be able to feel if the pump is actually spinning up.

If it is then its just not priming properly so you could try isolating that pump from the rest of the system and just plugging that in alone to your PSU and flick the power on and off in 2 or 3 second intervals which should get it going.

If you can't feel the pump starting up then its either bust or the impellor is jammed, in which case you will need to take it out of the system for closer inspection.

[Cutless009]

Argh I did that, no avail, but its seriously like.... theres air in 75% of the lines, but blowing into the res does nothing, like it wont move at all if I blow in the fill port. Here's a short movie of the bubble in the EK block:

Its running, and I did that with the 2-3 second intervals, and it just keeps making small burps of air as soon as I turn it on, like its almost all air in the line or something, its almost like Im not getting any more water into the lines at all.

[Baleful]

Are you turning everything on/off with the pump as well? If so you are asking to fry something man, I would hate to see you kill some hardware.

Jump your PSU where only the pumps are plugged in, is it possible for you to shoot some video of your res/pump combo while it's on?

[Cutless009]

Why would it fry something if there are no leaks? Ill brb with that vid for you.

[coolmiester]

try the 2-3 second intervals with the top of the reservoir off

[Cutless009]

http://s188.photobucket.com/albums/z6/Cutless1/Simplicity/?action=view&current=BleedingWoes2.flv

there you go, 1 cycle on/off of the res.

[RedRaider]

Cutless...

Quit turning the PSU on/off with all your hardware hooked up to it...

You should buy a little 12V PSU like I have at an electronics store or use the paperclip mid on a cheap computer psu and run the pump only.

You are asking for trouble...:nono:

[Cutless009]

D: I am, Im using a little 500 watter jumped, just the lights/fans are plugged into a single controller and thats what Im powering.

[coolmiester]

I've got it......the pump is petrified to turn on by the noise of all those fans :hypno:

[CrazyJoe]

Sorry, if you'd asked about 15 years ago ... I did live in Orlando. Managed the JD Penguins Night Club north of the Airport back then. :D

Definitely some sort of vapor lock. Too much air space in there to allow the pump discharge to push past it before the suction side of the pump starves. Have you already tried adding liquid to that fill tube into the fill hole on the XSPC res ? That way you could indirectly raise the level in the res above the other components.

[Jtrain]

i live about 2 hours from orlando but i can't really help you out as i've never built a wc system or had any experience with it

[Baleful]

OK cool, I thought you were turning everything on, not just the pump/fans.

It's hard to tell from your video, but you do have the fillport on the res open, right? (I made this mistake before which is why i ask :D)

Hmm.... I dunno man it's very strange. DDC's are proned to wigging out if the top is way to tight, maybe try backing off the screws just a little bit?

Have you tryed starting it up and shaking the hell out of the DDC while it's running?

[Cutless009]

yup the top is off the fillport, and I cant take it out and shake while its running cuz well, its really hard to get in and out of there. Feh. Ill figure it out Im sure, gonna try what that other guy said and fill up the fill tube with water.

[Xilikon]

If that doesn't work well, don't be afraid to shake and slap the pump a bit vigorously. If this doesn't work at all, disassemble the loop and make sure the top isn't screwed too tightly.

[Cutless009]

what happens if the top is screwed too tightly? Its screwed down to 10lb/ft of torque

[Xilikon]

if it is screwed too tightly, the impeller might have a problem moving without enough clearance.

[Cutless009]

oh no, its definitely spinning.

[Baleful]

The top can be to tight and the impellar will still spin, just not correctly. I had a similar problem when my top was to tight, I wasn't getting enough movement, and the pump would take 20-30 sec. to start up sometimes.

[bigslappy]

Cut try putting the pump @ the same level as the res & block (pump outside case ) fill each with water & clamp off with water filling everything attach tubes cycle the pump while flipping the case ..that fails then move the res out side case AND up high above everything

this is why i use cheap clear tubing when 1st building a loop

try & report back .. We will all figure it out for YA ..
