I might water cool my GPU using the NZXT Kraken G12 and a Corsair H55. My motherboard is the MSI B350M GAMING PRO. I am afraid I might not have enough fan headers. I am also scared that the NZXT Kraken G12 doesn't support my RX 480 Gaming G1. Thank you.

you can connect 2-3 fans to a single header (using simple splitter) without worries. most of the headers are rated at at least 1A. a single fan consumes much less. something like ~0.2-0.3A at full speed.
If you are too worried, get a powered PWM fan hub - it's about 10-15$ from silverstone, swiftech etc.
so basically you can have any amount o controllable fans.
what you actually want is:
1. add two front fans as intake - preferable static pressure optimized fans
2. add another fan to the top (close to rear) as exhaust.
to have positive pressure in case (much less dust gets in) set the front fans to spin ~15% faster than exhaust fans.

About your idea of using G12 - it's actually nice one. you can reuse this on the next card as well...

Yeah other than being bored or you have a full loop already it is completely waste of money. Even the Nvidia 10 series cards have no benefits besides lower temps.

The RX 480 will benefit from being under water but the cost of the block is half the value of the card.

What do you mean by case layout? I tried to set up a fan curve, but it made my computer really loud.

I can't get two more fans because I only have 2 system fan headers, unless I buy a splitter but it might not supply enough power to the fans.
