• SMCAMDProcessor.kext have no new changes since last release and thus was not included. You can still download the latest version from the most recent previous release.

Known issues

* Sliders in fan control panel might not display correctly.
Workaround: you can still drag at the correct position of sliders on each row to adjust fan speed.
This was fixed since Big Sur beta 8.

The experimental fan speed control was included in this release. At current stage only a very limited set of controllers are supported. You can open fan control menu to find out what SMC chip you have or whether your board is supported.
Please refer to this(#66) discussion for more updates or request for support.
