The replacement Mo-RA3 420 pro arrived today in Stainless steel, looks ace.
 
Wired it up and flushed the loop (minus the CPU block and the hydro copper), took nearly 20 ltrs to flush that bad boy out (distilled water)...
 
The dual pump draws 3.22amps while running flat out.
 
The Noctua 140mm fans draw 3.4amps for a less then a second and then drop to 1.47amps continuously, which worries me a little on the 2amp header, as I don't know how much of a spike of amps the fan header can take, the meter only just catches a flash of 3-3.5amps in a split second before dropping to 1.47, what do you think? Split them up? or power them directly from PSU? 
 

Big rads will need lots of distilled to flush with.    My rads in total are 120.9 worth while yours is 140.9 so it's close enough. lol
 
Careful when drawing that amps from the MB headers since on average or the standard was always 1 AMP per header unless that has since changed.
 
I'd power your stuff through the PSU and use the PWM signal to the headers unless you need more PWM headers your board doesn't have and you need something like a SPLITTY9 and a Aquaero 6 LT.    Assuming the PWM pumps are compatible to this controller.

Got some questions, started to build the PC today :-)

Power for the MB, I have connected the 24 pin and there is two 8 pin connectors next to it, connected both of those also... there is also an extra power connector on MB at the bottom, believe its pcie power, do I need to connect that also? If so no more CPU 8 pin connectors on psu or cables... do I use a VGA one?

Power for the kingpin, there are 3x 8 pin connectors on the side of the card, I have 3 VGA Cables, but only 2 are single and the 3rd is split to power two 8 pins off one cable... question is do I run 3 cables and have the one with the extra split just dangling, or use 2 cables and use one as a jumper to fill all 3 slots?

As the cpu is rotated, I have also rotated the Heatkilller Iv cpu block, with thr outlet at the top, to help purge bubbles, is that correct to mount it 90 degrees cw?

FAN header 1+2 do I use for pumps? I know I could bridge them together but I want to know if a pump fails.

Other than that decided I can’t mount GPU at the top so I will just get a standard vertical mount, can someone let me know the best quality one to buy?

You don't need both 8-pin CPU headers unless you're doing extreme OCing like LN2.  Check your manual which one to use and use the other for PCIe power.  Nothing wrong with adding that because it will increase stability for those lanes, especially high end RTX 2xxx GPUs.
 
As for powering your GPUs, always feed the GPU with it's own cable.  Never use splits since we've seen folks have stability issues before.
 
I'm a bit confused on your CPU WB question.  Your CPU socket is sideways and you matched the WB the same way?  If yes, that's fine as long as it's lining up and covered.
 
You could use both headers if they are PWM but I like using them together so they are being fed the exact PWM signal with only one tach in return.  I use my flow meter to keep an eye if a pump should fail or via audibles but these D5s are so darn silence though. lol
 
Can't help you on a GPU vertical mount as I can't remember what case we're talking about here.  (Make a signature and list your new PC in it and create a Mods rigs.

Edit: I think this is what you're looking for if I understood you correctly.

From z390 dark manual..


7. Dual 8-pin EPS Connector
The +12V EPS are comprised of 90 degree right-angle dual-dedicated power inputs for the CPU (See Page 41 for more specifics to the connector itself, and associated wiring/pinouts). Carefully choose the correct power cable by consulting with the installation manual for your power supply. This connector is designed only to work with an EPS or CPU cable. System builders may make the mistake of plugging in a PCIe 8-pin or 6+2-pin connector, which will prevent the board from POSTing and possibly short or damage the board. Although the cables appear similar, they are wired differently and attaching a PCIe cable to an EPS connector may cause damage to the motherboard.
Alternatively, if no power cable is connected or detected, the system will not POST and will hang at POST code “C.”
8. Supplemental PCIe 6-pin Power Connector
There is a 6-pin PCIe connector at the bottom of the motherboard (See Page 40 for more specifics to the connector itself, and associated wiring/pinouts). This connector provides dedicated power to the PCIe x16 slots, augmenting the +12V power provided by the 24-pin and the GPU directly.
This is optional for a single card solution, but is recommended for SLI, CFX, and dual-processor video cards.





So I’m a little confused as it says don’t use 6+2 pin in the power slot, as mb won’t post, but these are the only cables that came with the psu...

Why can’t they just give simple wiring diagrams instead of all the guess work...

The two cables I have plugged in say CPU On the sides of them... does this mean I’ve done right?

I’m just flushing out the clear pipes and all the in sides have gone foggy, I used distilled water and over 20ltrs, why has the EK duraclear tube fogged up after 12 hours?

 
Foggy as in cloudy?  Is it temporarily or permanent?
 
If that tubing doesn't fair well, I highly recommend PrimoChill Advanced LRT.

I’ve ordered the Lian-Li Vertical gpu mount and cable, hopefully it will work well as no one seems to know much about these so had to just take the risk, suck it and see.

I linked you the one that should be for your case.

I have booted it for first time today :-)

Let the bot do a oc for me (I know), did 5200MHz at 1.355volt.

Used the stress test for 2 hours, ran at 64-65degrees c.

I presume thats decent starting point?

Is there anything else I should do before installing windows? Set fan speeds already and xmp for memory.
