Is the fan connector just the RPM reporting wire, or does it have all 3 wires for some reason?
Its got all three
Is this the pump you've got?
If if is, the fan connector isn't used for power anyway, it's just RPM reporting and PWM signal, so either plug it into your motherboard for that, or you can just unplug it and the pump will run at 100% all the time.
nah mate its this pump combo
That's the same pump...
oh right...it looks different
So yeah, I don't think you're having pump problems.
Try turning your pump up to 100% (or unplug it from the motherboard) then move your case around a bunch (lay it on its side, back, upside down, etc.) and see how much air comes out. If that doesn't fix it, you might have to pull the GPU block apart and have a look inside.
I'm starting to believe that too...
Ok I think we found the issue but the better question is why? what a look at this video
Mate you're at the point not where you have no choice but to tear down the loop. It's obvious even without the thermal camera that one gpu isn't getting cooled sufficiently.
It's either a blockage or a bad mount which I doubt. A bad mount usually results in temps spiking rapidly as there is poor contact with the block. But since you are pulling the loop down there is no harm in checking the mount whilst you're at it.
Also I'd be going back to series as there is really no reason to run parallel in such a simple loop and a D5. Temp wise you will only be looking at a few degree's difference between GPU's.
I have reconfigured my loop and ran the thermal scanner again and it looks a lot healthier. See Photo / Video
so its ok now? good work
what are your temps like?
my 290x's in series have ~1 degree variance (iirc, that rig is in pieces)
looks pretty clear to me in that first thermal vid that the flow:
but you know, i could be wrong...
All the thermal scanner is doing is showing you what you already know - ie the first GPU/block has an issue.
By re-configuring it as a serial connection, all you are doing is masking the problem.
Pretty much confirms now that you have some blockage issue in the first GPU block.
