Omen 25L Case Swap (90b Fan Error)

[Karsonxx]

TLDR: 90B fan error on 25L case swap to Antec C5

Hey all,

Whether its stupidity or determination, I've pretty much set out to test the limits to the Hanal MB (EB89).

I wanted to make this post in essence to show its potential and to make note of where my performance currently stands as I'll piece mail this build as far as I can.

Current Specs (pics will be post below as well)

MOBO: Hanal HP MB

CPU: Ryzen 7 5700G

GPU: RTX 3060Ti 8Gb

RAM: Kingston Fury (OEM Sticks) two at 16gb and two at 8gb

Planned upgrades: 

CPU: Ryzen 7 5700x3d 

CPU Cooler & PSU: haven't decided yet what would best tailor the build

GPU: 3060 16gb or 12gb

Secondary NVME drive

Yesterday I case swapped from the OEM 25L case in white to the Antec C5 mid tower case. So far everything is running and benching as it should. Also repasted the CPU, which I feel was juristically needed. The only issues to note from doing this is seen as stated above. Upon boot I'm getting a 90B fan error, and going from 2 case fans to 7 has me a little confused as to why. The Antec C5's case fans run to a central hub behind the secondary side panel, which are connect to the PSU via SATA connection, and also connect to the MOBO via SYSFAN connection. The CPU cooler is connected to the MOBO via CFAN/PUMP and to a Zone 3 connection on the bottom right-hand side of the MOBO. 

Current temp's as I'm typing this are great and under load I've only seen the GPU and CPU reach low a low 70 degree Celsius. 

Has anyone experienced this issue before? It may be a common wiring mistake on my behalf, but if not would I be okay to just disregard this error? Thanks!

Bonus Question: Is it even worth it running two 16Gb sticks in my 1 & 3 slots, and 8Gb in the other 2 & 4 slots?

swapping CPU cooler RGB cable to Zone 1 after realizing it's purpose. Might also add back an Oem fan to the top of the case as well, will update with results later!
