There are so many ways vendors implement that stuff, I don’t see how iX could ever provide that feature outside their own limited and well known range of enterprise appliances.
But if you invested the cash to get a real server mainboard with IPMI, you already have a UI for that.
I have supermicro boards, so yeah I have invested in real server hardware. Thanks for your concern though. Supermicro only exposes 3 fan settings in their web interface for IPMI.
