Good afternoon everyone,

I recently upgraded my Bios for the first time to the latest to 4.03. When I did this I lost all access to Fan Controls and Temperature in the bios. I tried to downgrade and the board would not boot anymore. I had to flash back to 4.03 and then it worked again but still no Fan Controls or Temperature readings in the bios. In windows you can see the temperatures but need an app for fan controls. I use this for my server under UnRaid and would love to actually be able to manage my fans again. Any idea what the correct process would be to back and regain my fan controls?

Thanks!!
