Other ASRock Rack motherboards can change the fan speed via ipmi raw commands:
see Fan speed control on C2750D4I/C2550D4I Asrock boards
The option to set the fan speed 10% - 100%, in 10% increments is available in the BIOS, so I'm thinking it can be set via IPMI for the ASRock Rack EP2C602-4L/D16 .
If the ipmi raw command is found, then its possible to set the fan speed based on a temperature sensor reading via script.
I've contacted ASRock Rack support and they are responsive, waiting to hear back from the relevant department / BIOS engineers.
In the meantime, does anyone know how to find dump ipmi raw values?
If thats possible, changing the fan speed values in the BIOS and matching them up to values in the IPMI dump will make this straightforward. Not to mention this is generic method capable of providing a similar solution on any IPMI capable motherboard with PWM fan control.
