First off, sorry for the wall of text, but any help would be hugely appreciated.
This weekend I finished (or thought I did..) a build using the Antec Flux, which has a fan controller on the back of the case - diagram included below.
Motherboard has 4 Chassis Fan Connections and 2 CPU Fan connections. Diagram also linked below.
Diagram 1: Antec Case Fan Controller/Hub - View: https://imgur.com/a/9dVT9g0
Diagram 2: MOBO Layout for x870e Taichi Lite - View: https://imgur.com/a/T8163Qq
I am using 5 Lian Li SL Infinity Fans
3x 120 in the front for intake (Daisy chained/connected)
1x 140 in rear for exhaust
1x 120 in top for exhaust
All fans are plugged into the 4PIN and 3PIN ARGB connections on the case included controller/hub from Diagram 1
Originally, I connected the 4 pin PWM/3 pin ARGB connectors of the controller itself to the motherboard through the Chassis Fan 3 Header (#26 in the MOBO Diagram) and the 3Pin ARGB Connector to the MOBO through Addressable LED 1 (#32 in MOBO diagram.)
First boot and everything was running okay except for my case fans - they're running full speed regardless of load.
I then go in BIOs and see that the two fans on my Phantom Spirit cooler are running fine (These are connected to the CPU fan headers), but that Chassis Fan 3 (which the entire case fan hub is connected to) is running at max speed.
I try changing Control Method from Auto to PWM in Bios and no luck. I then switch the PWM connection from my case's fan hub from Chassis Fan 3 to Chassis Fan 1. This appears to rectify the issue and my case fans begin adjusting to load and become *significantly* quieter.
Then the problem just starts again and fans go full bore out of nowhere and persists on restart. I think to myself maybe the 4 Pin cable connecting to the hub is faulty, or the 4PIN/ARGB connector on the hub itself is faulty, so then I remove and reseat said connector on the hub (top left cable in the below photo.
Literally just unplugged it and plugged it back in exactly as you see in link below)

I then start the computer and problem seems fixed. Load into Baldurs Gate 3 to see how the system responds - cool as a cucumber and quiet as can be.
I go to bed last night thinking I fixed the problem and that the 4PIN/ARGB connection on the hub was just loose.
Before I leave for work this morning, I turn on the PC just to check and...PC is back to running all case fans full speed. I had touched nothing since last night and am now at a loss of how to proceed. I was so certain it was something with the connector or the hub connection but now I have no idea. Could it be something with the MOBO?
Should I try connecting the 4 pin PWM connector from the hub into one of the CPU fan headers instead? (Would then run both CPU fans via a splitter to one CPU Fan header)
