ROG x670e Hero i2C errors on Arch Linux

[from_planet_zeb]

I'm running Arch linux on my system which has an x670e hero board with an AMD 9950x processor. The computer runs great except I get an error on boot that says it couldn't connect an i2C client and I am unable to control the rgb on my fans or the fan speed from software.

The bios can control the fans and my case has a button to cycle the rgb colors but software does not recognize the hardware.

I haven't seen any other reports of this issue anywhere on the internet so I'm trying to figure out if I have some type of failure with my board or if there is just an incompatibility with linux.

I use an integrated fan and pump control (arch user too)

Do you control it through software? What software do you control your fans with? I can control my fans through the bios but using something like cooler control it doesn't seem to work.

I guess he can't get access to device because he didn't activate some driver. It's not software question, it's about os configuration and hardware detection

Yeah, I guess that's what I'm asking. Is there a specific driver to get fans working via software on Arch linux? You mentioned you had it working so what did you need to do beyond the vanilla arch install? Thanks for any insight.
