can you post some pics of the loop (in and out specially) of the pumps?

I have two pumps so one dead one won't completely stop the flow ... or will it?

I can ... but tomorrow. All of my tubes are solid (white, green, black) so you won't see any liquid movement. I am going to swap out a section of the green tubing with clear so that you can see liquid flow.

I will drain some water out of the loop so that the reservoir return port is above the water line.

no need to drain. I just want to see the layout of the loop. It seems one pump is feeding directly the other. Just want to understand the loop order. But if you are going to drain it I would test each pump separetly out of the case in a simple loop to check how it goes. Those are the koolance d5 tops?

No, it will have only very little effect on flow.

BTW that pump noise.... Not sure what's worse, fingernails being scratched on an old school blackboard or your pump noise... smile.gif

Do note that you can easily find yourself in a situation whereby a pump may have a fair amount of 'stuck' air (air lock scenario) inside its volute so when it spins up it doesn't really flow any water as such. Odd thing in your case is that you have 2 pumps so I would have thought that at least one of them would have pumped coolant... unless both have air in their volutes.

The pumps are both Aquacomputer D5 Pump Mechanics with RPM Signal.
The headers are both Watercool HEATKILLER® D5-TOP.

Yes ... the headers are facing each other and the outlet from the right pump flows straight into the inlet in the left pump .. a distance of about 30mm.

I actually want to document the flow in total (for feedback biggrin.gif) but I can't do that tonight. The plumbing around the pumps is best illustrated in this post from my build log (includes video).

One is full of air bubbles the other is full of air that's why there is no movement in his res I would imagine, could be wrong but that other pump sounds dry/dead.

Just finished the new build today...

16mm tubing, double bending these fat asses is not easy...still gotta tidy up some cables and put the PCI covers back on then i'm done..

I drained a little out of the loop so that I could see the reservoir return port ... only to find that the flow is hopeless. Much better to call it a dribble. I rocked the whole unit back and forth, front and back, left and right and it greatly improved the flow (more a gush now) ... but the air noise from the pumps jumped (only the left pump is pumping ... the right pump is sitting there laughing at me).

How do you remove air bubbles ... just run the loop a lot?

That looks amazing buddy. What kind of rizer cable did you use? I had a go at at that about six months ago and the rizer cable I used was a piece of **** and I couldn't get the GPU to go full x16 even though the cable was apparently specd at that.

Also not to nitpick, it's a much better job than I could have done 👍, but are those fans only secured by two screws each? Was the spacing off?

To be honest I wouldn't have even noticed if screws were black, but it seems you had to use replacements(?) and since they're that color it kind of stood out.

Screws, are black, just the reflection....yeah i just bolted stuff up real quick to snap a pic...tomorrow i will fine tune all the details, and shrink wrap the pump wiring...i dont know why EK still doesn't sleeve their wirings...or at least make the wires black.


As for the riser cable, i used the Lian Li one that came on my last O6S, i had an extra because i was going to SLI but then i couldn't fit them in the case...as far as i know, these are the only ones that give u the full 16 lanes, other cables don't even show a video lol.
