So, bit of a conundrum...
 
Have one massive KP card and waterblock and 3 Hydro Cooper for reference cards (2 1080 Ti's, 1 Titan Xp - same pcb, 1 KP). If I flow up from bottom (FE, FE, Xp, KP) going to get quite a bit of head loss as I get to top Card (KP) -- if I put them all on the same loop. I could go 2 pumps in series and double my pump discharge head - that would probably be enough pressure to push through loop at a decent velocity but quite a bit of flow restriction coming up from bottom which would translate into inlet side pressure on the Hydro Copper.
 
Options:
1 - 2 loops, one for the reference cards and one for the KP
2 - 1 Loop, 2 pumps in series pushing flow up through from reference cards at bottom to KP
3 - 1 Loop, 2 pumps in series pushing flow up through KP first at bottom then through reference cards
4 - other?
 
If I go with 2 loops, then the CPU gets an all-in-one. No way I'm gonna put 3 loops together in a single case. The KP block is going to have MUCH more flow than the HC, may get some more minor frictions losses but simply a much bigger block (see pics)
 
Advice?

    Block height for the tube connection between the ref card and KP will most likely be different and may be impossible to connect all 3 together. If so go with CPU and KP in 1 loop and the 2 ref cards in another. No idea if you'll have space to connect a water line between the Ref and KP so you might have to have both water connections on the bottom ref block and the top connections on the KP. If you know what I mean. The water flow will still flow threw both ref blocks.
     
    CPU block will most likely kill the flow a lot more then the GPU blocks. So if you can do all 3 on 1 pump and the other pump just for the cpu.. that setup would be best.

    Yeah... It would be kinda crazy piping coming out of the HC block then up into the KP block. Several 90 deg bends up and over. I like that the HC has a horizontal out - one less 90.

    Total cards would be 4 - a rather ambitious setup.

    I’m thinking I’m gonna have to break out the KP on its own loop. Then I’ll ponder whether or not to run that loop through the CPU or leave the CPU for an AIO.

    Would prefer to keep all GPU’s on same loop... 🤔
