The Pro cooler only needs the MB connection to report a pump speed to the BIOS.
You mean I can unplug the 3-pin from the pump and just have the USB corsair link cable and sata power connected? Freeing up one more header would be perfect.

Connecting the noctua fans directly to the motherboard via a splitter still doesn't grant me the ability to control its speeds between 0 and 99%. So it's either a motherboard issue or a problem with the fans. Seeing as other fans worked just fine, I think I will return the industrial ones and replace them with chromax fans.

The Noctua Industrial series were intended for their named use and there are some different elements to them than the rest of the Noctua line. It is common for people to have control issues with the 3000 rpm variant on Corsair controllers. Not so much on the 2000 rpm PWM and I used the A14i 2000 rpm for several years on my H115i Pro and continue to do so on my Commander Pro. Another user recently complained of similar control issues, but they were using the Platinum cooler which likely has a different PWM controller than the Pro line. I had attributed it to that, but perhaps there has been a change on the Noctua end as well. All my Industrial F12 and A14s are first issue from several years back.
If you are determined to use those fans, you may need to move to MB control.
I've played around with the bios settings and nothing seems to fix the problem. I'm somewhat determined to use these fans as I have three other noctua fans in the system. The fans are new and I may have accidentally tore up one box a little so It would be hard returning them and swapping them for the Noctua Chromax ones. Seems I have to resort to MB control.
With the pump using one fan header, I only have 2 available fan headers for 5 fans. I'll have to use a three-way splitter for the case fans which I feel uncomfortable using even though the fans fall under the 1 Amp limit (0,18 A + 0,13 A + 0,1 A). I'll also loose the ability to fine tune each fan for noise.

When I plug the stock corsair fans into the pump fan splitter, I am able to set the fan "fixed %" value between 0% and 100% and the fans will adjust rpm, just like it should. When i plug in the Noctua NF-F12 industrialPPC 2000 PWM fans that I intended to use with this AIO, the fans run at 0 rpm when the "fixed %" is set between 0-99%. When I put the value to 100% the fans will then turn on to 100%. so the problem is that I am unable to get the fan to run at any percent value between 0-99%. I've tried all the different curves as well as custom curves but the fans will still only spin at either 0 or 100%. I'm using Corsair link version 4.9.9.3 and I've tried using ICUE with no avail. The pump 3-pin is connected to CPU-Pump fan header; Sata-power and the corsair link usb cable are properly connected. I'd appreciate some help on this.

Freeing up that fan header and using it for the Noctua fans got them to work as intended. I am finally able to control them! :) Won't be returning them after all. Thank you so much for the help; I really appreciate it :biggrin:
