Build Advice Chassis Fans not giving a reading in the BIOS ?

[cchamiltonn]

I recently picked up a Rog STRIX B650e-f gaming motherboard and I am having sometrouble getting thye system to pickup my case fans. My NZXT AIO is plugged into the AIO header. All together I have 9 Lian Li uni fan SL20 RGB fans. 3 of which are daisy chained and plugged into my CPU header. The other 6 are plugged into my Lian Li fan controller which is plugged into a chassis fan header. My problem is that the six fans plugged into the fan controller aren't giving a reading to the motherboard. I get a reading from the AIO and the three fans in the CPU header.

Before switching motherboards I had a Gigabyte AORUS Elite V1 and had all nine fans in the fan controller which I believe I had plugged into the CPU header and never noticed an issue, in fact, the system seems to be louder with my current setup.

I would appreciate any help, I feel like the cassis fans are just running at default speed all the time without being controlled by anything and I have no idea how to fix it. Any questions let me know

Just curious, did you reinstall your OS after the motherboard swap? as for your motherboard, you have a CPU_OPT header, use that in place of the chassis headers. One more thing, did you use the L-connect app? Here is a guide to the app;
