Have 9 fans but only 6 headers on commander pro
 
If I connect corsairís ml non led or rgb fans to the mobo pwm header with a spliter will it beable to be controled through iCUE?

Yes, but both fans on the splitters will run at the same speed. Also, don't put more than one splitter per Commander PWM header, you'll draw to much power for the commander to handle.

So if I use a 3 way spliter on my mobo i can have 3 fans controled in corsair icue? Will my mobo beable to handle 3 fans on one pwm? My mobo idea is asus z370 prime a

No. Your motherboard headers are controlled by your BIOS settings or whatever software your motherboard vendor makes available. iCUE controls peripherals and internal devices, one of which is a Corsair Commander Pro. That is a fan controller and RGB interface tool. If you want fan control, you need that. Either way, you will want the Commander Pro or Lighting Node Pro for RGB control. See the sticky here for more information. There are some requirements to set this up.

The overwhelming majority of motherboard fan headers have a 1.0A current limit. Always check your manual to verify. Obviously this also very fan specific, so you have to total it up on a model by model basis. Current flow is very dynamic and you should not assume max limits are hard caps. Always leave some room. A 0.80A total is safe for most things. I occasionally push it 0.90A with fans that have been tried and tested. I don't recommend that for people unless they are very comfortable with how there gear works or anyone who is risk adverse.

I wouldn't do 3 for the reasons c-attack mentioned. The current draw of PWM headers is usually around 1 Amp with some headroom build into better boards but its really not worth possibly killing a header or whole board.

to add

Not Officially supported but there is no reason why you can not use Fan header Splitter cables on the Commander Pro (note there is a 1A limitation per fan header and a 4.5A limitation for the entire unit

More info on fan specs and power draw in the linked thread below
