What i know is that i have a cpu_fan and cpu_opt 4 pin headers.

Is it necessary/required for the AIO to be set to 100% speed in BIOS? I have mine on "Performance Mode" with a pump curve on NZXT cam.Generally you would use the CPU_FAN header for the pump, and you would set it to 100% speed regardless of temperature. Full time 100% operation for the pump. But it depends really on what cooler you have because these days many coolers do their own thing and do not all share the same recommendations for where to connect various things at. If you don't have a model where the fans are controlled separately and must also be connected to that header, then another configuration might be necessary. Also depends on if it is a board where the CPU_OPT is a simple duplication of the settings of the CPU_FAN header, or whether the CPU_OPT is independently controllable.
What is your cooler model?
Cooler is Corsair H55 CW-9060010-WW, 3 pin pump power and 3 pin radiator fan. But I have done a lot of research regarding where the appropriate place to plug in the pump's power some have and the answer isn't clear at all. People say cpu_fan, cpu_opt, aio_pump, and even suggesting getting a molex adapter to plug directly into the PSU? So I had to resort to asking where i should plug it for my exact motherboard. Im just looking where i could plug it in to get the best performance from the pump. Also another question, will this case https://www.amazon.com/CORSAIR-Carbide-SPEC-Omega-Mid-Tower-Tempered/dp/B017XPPB1M/ref=sr_1_21?dchild=1&keywords=corsair+spec04&qid=1590296496&s=electronics&sr=1-21&th=1 fit the kraken x42.Generally you would use the CPU_FAN header for the pump, and you would set it to 100% speed regardless of temperature.

The AIO pump can be used on either SYS or CPU-OPT headers in your case (since you have both) - the speed should be near 100%. Really the Radiator fan should be on the CPU header to take advantage of PWM (CPU-OPT also in your case).
generally the sys headers are DC control (primary), some have PWM optional - so either one is fine for pump operation and some pumps still have the 3-pin header anyway.
There are NO "sys" headers on this board. There are ONLY CPU and chassis (CHA) headers. The radiator fan AND pump cannot "take advantage of PWM" since they are three pin fan and pump connectors, and are not capable of being used with PWM.
Let's make sure we know what we are actually talking about, before we start talking. BA removed for inaccuracy.
