We recently got a new server at work (R282-Z94), and the fans are going at full blast all the time. The management web interface shows all the sensors as disabled. I’m not sure why this is happening, and I can’t find anyone else seeing this issue.
I saw something like this 15 years ago maybe. Tech support thought it may have had the wrong BIOS flashed onto it. We reflashed it and reset the BIOS configuration and then it just worked.
I would suggest either Gigabyte or your OEM builder tech support. But the BIOS thing might help. Make sure you get the flash file that is exactly for your board model and revision number.
