According to my research your board uses a NCT6686D which is included with the NCT6683 driver. After a Google search for that driver I found a post here on this forum.
Note that the kernel website says for Non-Intel systems that you need to force it to load.
They included that link in the thread. They also explain how to ID your chip.
Here’s the thread about it.

Also note that CoolerControl says this.
CoolerControl depends on Hwmon kernel drivers and
liquidctl to access and control supported hardware. Note
that your hardware is not guaranteed to be supported, as this depends on open-source
drivers and contributors. The following are the steps you should take to maximize hardware
coverage:
Install lm-sensors and run sudo sensors-detect. For more details see the
Arch Wiki. Additionally, you can
check out the official lm-sensors repository
for tips on manually loading unofficial kernel modules for hardware that isn't supported
out-of-the-box yet.
