So, after 10 minutes of googling without getting an answer. I've come here. The aio i ordered says that if using a y splitter for the aio fans using the cpu_opt port is recommended heavily. I wonder why since its only an 1A output while the motherboard does have a 3A one which would give all the fans the basic 1A of power right?

Normal fans really don't need 1A to run, it's usually a quarter or fifth of that (0.2-0.25A), so it doesn't really matter. The usual config is to have the AIO pump plugged into whatever header that runs it at 100% speed all the time, and the radiator fans plugged into the CPU_fan header to be controlled according to the CPU temperature. Some people control the pump's speed too, but as far as I know it's better for the pump to just run it at full speed all the time.
