The manual for the kryographics Pascal for NVIDIA TITAN X states in step 5, "Be sure not to connect any water blocks in parallel but only consecutively".
To that end, it would be useful if aqaucomputer provided a kryoconnect for these new blocks that could be made to go serial.
You could take an existing kryoconnect bridge, bore a hole in the side, at the center, to provide a passage between the two longitudinal bores.
Then seal the outside wall at the center bore, and included one additional headless set screw to direct flow internally.
