Question AIO pump vs cpu fan header on Asus Z390 gaming E

[KarlSpuhl]

I am building my first PC. I am using the Asus Rog Strix Z390 Gaming-E mobo and a Thermaltake Floe Riing 360 AIO cooler. The board has a cpu_opt header, cpu_fan header and an aio_pump header. The small 40mmx40mm fan provided with the board is plugged into cpu_opt per the illustration in the manual. The AIO has the RGB wire attached to my one of my TT fan controllers and the other wire attached to the AIO_PUMP header. The cpu_fan header is not being used currently. When I turned on the system to test it, I got an error saying I had no cpu fan detected. Will this be a problem? Should I put the small 40x40 fan in the cpu_fan header instead of the opt header? How would I know if the AIO pump was not pumping? I was relieved that everything seems to work and it posted; I had already done 80% of the work installing parts and cable-managing. Thanks.

You must have some fan connected to CPU_FAN header. AIO_PUMP header is ovoiously for pump but radiator fan(s) should be connected to CPU_FAN and OPT_FAN

So my radiator fans are currently attached to one of three Thermaltake fan controllers which will be controlled by Thermaltake's RGB+ fan controller software. One end of the three daisy-chained controllers is attached to a cable that plugs into a USB 2.0 header on my mobo. They are not pwm fans; they are molex driven. Each fan has it's own jack on one of the controllers. And apparently since the pump's rgb wire is attached to one of the controllers, I assume the pump speed is controlled by TT RGB software. Yes? The video i saw on YouTube about how to set up this AIO said to attach the other wire to the cpu_fan header. But I don't know if he had a dedicated aio header. Can I plug the small 40x40 fan into the cpu_fan header just to get a boot? If I use the cpu_fan header instead of the AIO header, will my pump speed be controlled by my mobo's bios or by the TT software? I saw a similar thread here about this subject here but it wasn't an exact answer.

Controller itself should get signal from and to CPU_FAN header because that one is providing CPU temperature so fans can be regulated by it.

CountMike, thanks for all your help. I plugged the wire from the pump that was plugged into the AIO_fan heaader and plugged it into the cpu_fan header. So now the cpu_fan header is connected to the pump and the pump is connected by its other wire to one of the TT fan controllers. I powered up the system and now it boots correctly and brings me to the bios (don't heve windows installed yet.) instead of giving me a hardware failure error. Under this setup, will my fans be controlled by the bios or the TT software or a combination of both? From your previous statement, it sounds like it would be the bios that is controlling them. For reference this is the YouTube video I referenced about how to set up this Thermaltake Floe Riing 360 cooler. If you want to watch it, you can probably start at the 5:00 mark or several seconds before it. It's about 30 minutes total.
