Hi guys,
I'm having issues setting fan speeds on a 4027GR-TR Supermicro system.
System has 8 fans for both CPU/GPU/chassis cooling, and are controlled via the IPMI.
I've followed this guide from PigLover but it doesn't seem to work with this system.

I only have two default options for fan speeds: Optimal and Full.
I'm able to check what mode it's set to with the following command;
This outputs 01 or 02 (Full or Optimal).
But... When I try to set the fans to a specific duty cycle (40%, 50%, etc.) using the following command;
I get the following error;
I've tried different variations of the same command, and all of them spit out the same error message.
I don't think this system has different fan zones (Zone 1 for CPU, Zone 2 for peripherals, etc.) as all the 8 fans in the system are designed to cool everything. I'm thinking this may have something to do with why it's not working.
Any ideas?
Thanks!
