I want to do a custom water block and loop with a 5090. I am looking for information on the release cycle and reliability of a new series of GPUs water blocks. Some questions:

• Are block failures higher on initial releases? Is it better to wait a few months?
• Are block sizing/tolerance issues higher with initial releases?
• Are there block reliability differences between founders’ editions and partner boards?
• For partner boards, is it better to aim for an OC version of the board (assuming it has better silicon, power delivery, etc.)?
• Are there any partner brands that get more water block love than the rest?

I appreciate any help you can provide.

Side notes: I am experienced in building PCs (component selection, overclocking, airflow, etc.) I just haven’t done my own custom GPU block.
