I'm building my first PC and I'm super excited! However, I'm stuck on how to manage the cables for my AIO cooler since my motherboard, a B760M, doesn't have an AIO_PUMP header. Should I connect the AIO cooler to the CPU_FAN header instead and then connect the radiator fans to the SYS_FAN headers? I only see a CPU_FAN and three SYS_FAN. I'm not really sure about this part as it's my first time, and I'd really appreciate any guidance. Thanks!

You might not have mentioned the specific AIO model, but generally speaking, you can connect your pump to the CPU_FAN header. Just make sure to tweak the PWM curve in the BIOS so that it runs at full speed since AIO_PUMP typically does that by default. The SYS_FAN headers are typically safe for the radiator fans. Just refer to your motherboard manual for any specifics.
Check if your AIO has separate cables for the pump and fans. If it’s a single cable, you can plug that into the CPU_FAN header. If they're separate, plug the pump into CPU_FAN and the fans into SYS_FAN. Just ensure you configure the pump header to run at a higher speed. You don't want it cooling down too much when the temperatures drop.
Thank you very much, I'll give that a try!
