So I'm not gonna lie, I have not read all 56 pages of this thread.
I have a Dell Poweredge T420 (12th gen).
Is there any chance of this plugin controlling the fans, or is it still only for those 2 boards mentioned in the OP?
EDIT: Also, I'm doing something wrong, since when I run any "ipmitool" command from the terminal, I get the output "bash: ipmitool: command not found".
What key step have I missed?
