I'm working on a build using the ASRock B850M Steel Legend motherboard, but I'm a bit confused about connecting my AIO pump. I'm using a Thermalright Aqua Elite 360, and it appears there aren't any clear AIO pump headers on my motherboard. The manual suggests connecting it to a WATER PUMP or CPU OPT header, but my board doesn't have those. Can anyone advise on the best way to connect this?

You're right that many B850 boards lack a dedicated AIO pump header, but don’t sweat it! You can connect the pump to the CPU fan header or a CPU optional header. Just set the fan curve to keep it running between 70% to 90% for optimal performance.
You can actually use any of the regular fan headers like CHA_1 for your pump. They should work just fine. It's a common workaround since some B850 boards skip the dedicated AIO pump header.
Can I set the fan speed to be constant for both the CPU_FAN and CHA_FAN headers? I see an extra fan spot at the bottom, and that would help my cable management. I’m new to this and want to avoid redoing everything!
