Well I have been pulling my hair out for around a week now. and I hope you guys can sugest or perhaps know what is going on.

I have had the colzero acyrilc parts for my corsair 900d lying around for some time. so I decided to put them in my case.

To put them all in I had to take everything out of the case.

The watercooling loop was working fine with nps I carefully took all components out of the case carefuly putting them on the side.,i then flushed them all out with distilled water and left them on the side until I had finished my case. I finishe dmy case and procded to put all of my watercooling loop back in. which I did.

I fired up windows did the upgrade to windows 10 then did a fresh install of windows. all seemed fine until I checked my cpu temp via coretemp and realtemp. omg 60-70c idle. I then installed aquasuite 2015 to check my flow. it was showing 0 liters per hour. I then felt around the cpu area my god it was hot. the actual cpu waterblock was really hot to the touch and so was the tubing.

To me this indicated that the water was not flowing around the system just hovering standing still. I took the rear side panel of and noticed the tube from the rad out to the flow meter was completely empty of water.

I went into the bios to check the pump was working it showed 4700 or so rpm so the pump was moving I sped the pump up and down via the control under the pump and still nothing.

After several drains refills . replacing the pump. adding another d5 vario. changing the cpu block still nothing. I then proceded to cut out the hardwarelabs nemisi 480 rad out and try that still the same no flow.

I then decided to go back to basics and make the loop outside of the case.

with the following components

OcUK Tech Lab - XSPC D5 Vario Pump & EK-D5 X-RES 140 CSQ Value Combo
EK Water Blocks EK-Supremacy EVO - Nickel (Original CSQ)
Hardware labs black ice nemesis gtx 480

also tried

blackice gen 2 extream 360 rad
ek waterblocks supreme hf cpu block

loop order

this is the one I tried first time.

pump rescombo out>cpu in>cpu out>rad in<rad out>pump rescombo in

when this did not work I tried the following.

pumpres out>rad in>rad out>cpu in>cpu out>pump res in.

No mater what I do I cannot get rid of the small pockets of bubbles which normaly would work themselves out and I would still get water flow. now can I get any sort of flow.

I am completely stumped any idea please. atm I'm stuck with a coolermaster cracken aio 120 cooler which isn't coping very well.
 
Just sounds like an airlock you need to tip your case about and try to work it out. Powering up the system without checking youve got flow first is a noob mistake, your lucky there was no leaks. I ALWAYS connect power only to the pump and run the loop at least for 15-20 mins and check the flows ok and no leaks and work out any air locks.

To test the pump, remove it from the system and connect a res filled with liquid (tap water if i was you) aim it somewhere and power it up should throw the fluid a good meter at least
 
Indeed an odd one, it should certainly move some water even with a load of bubbles it should still flow if there is no flow the bubbles will never move out the system.

Just a trial and error fix, test the pump as suggested.

It may be the Windows 10 Stalker mode as it sends everything to their servers same sort of load on the system as a game :)
 
Can you hear the pump running?
Can you see the water in the res move (at full pump speed this should be practically bubbling).

This doesn't sound like an air bubble, as you wouldn't get the same bubble on two different attempts. If you're getting no flow still, then it's a blockage.

If blockage, make up 2 pieces of tube and place them in one component at a time. Get a funnel and pour water into the "IN" of that component, and you should get water pouring from the "OUT". Basically, flush every block.

I did check there was no leaks I did a 24 hour leak test.
when I discovered I had a big airbubble I did move the case from side to side upside down left eright ect ect. it would not move.

And I have tested "both pumps" outside of the case, hense the loop I currently have wich is outside the case.

thank you for the reply

I can defo hear the pump is on. and I can feel it is on. I tested it via the bios also to make sur eit was spinning ie the rpms. I also tested the various settings ie 1-5 5 having the most vibrations and humming and 1 hardly feel it ect ect.

If your pump was pumping against a blocked end, it wouldn't last long.

Are you sure you aren't getting any kind of flow at all? I ask, because it seems unlikely.

Some photos of your loop would help. Where are you at with it just now, is the loop in tact or have you got everything stripped?

Sorry I thought I had said.

Iwhen I took everything out of my case I did clean and flush everything out with tap water then a final clean with dionised water. that was the pump/cpu block. and the 2 rads. water was flowing as it should be.

Everything atm is outside of my case in a temp loop.

I did think there was a blockage in the cpu block so I changed it and still had the same results. I cleaned the rads out and the water was flowing out so I presumed it was not the rads that was blocked.

Where I am atm is the entire temp rig on a table outside my case.
atm I am using a allinone type coolermaster thing which is struggling lol.

It seems that both pumps I have both d5 varios do nto have the oompth to pump air out of the loop. although it should have.

I tripel made sure I was going from the out port of the pump res combo I also made sure I was using the in port of the cpu blocks I'm utterly stumped
 
As I said its as if the pump res combo just does nto have the oompth to pump water strong enough to get all air out, I do know and am well aware if there are big pockets of air it will prevent the water going around, but even now its outside the case its really really hard to get the bubbles out , even though I have free relm to move the cpu water block and rad around. something is just not right, The one time I attempted to get air out of the loop I spent a solid 18 hours trying to bleed it, and still there was huge pockets of air.

It is really putting me of the d5 vario pump res combo. I think next month I'm going to be buying one of these :

EK Water Blocks EK-Dual DDC 3.2 PWM X-TOP With Dual Laing 18w DDC Pumps
https://www.overclockers.co.uk/showproduct.php?prodid=WC-564-EK&groupid=962&catid=2141

With either the res separate or with the pump res adapter.

It is also making me loose faith in watercooling
