Hello, thank you for your work. I have the B550gaming gen3 (https://download.msi.com/archive/mnu_exe/mb/B550GAMINGGEN3.pdf)

I see this when the module is loaded:

~$ sudo dmesg |grep nct6687
[    4.650787] nct6687: loading out-of-tree module taints kernel.

and these weird results:

Hello, probably the chipset is not compliant nct6687 but a nct6775 compliant or nct6683.

To check it use sensors-detect tool. or load manualy module nct6775 or nct6683 and check results

waanito commented 2 months ago

Hello, thanks. unloading nst6687 and re-running sensors-detect it now uses built in nct6775

Found `Nuvoton NCT6797D Super IO Sensors'                   Success!
    (address 0xa20, driver `nct6775')

which has better results but not quite there. I'll keep at it and report back here for others benefit once I solve. Thanks for all your help.

I know, i have a MB with this chipset.
