I have one Supermicro server with a X9DRW board, BIOS v1.0a, that does not seem to have any way of controlling fan speed. I've looked through the entire BIOS, including the usual location of Advanced->Hardware Health->Fan Speed Control.
The reason why I am attempting to change the setting is that our other servers with the same motherboard and BIOS revision are running their fans between 5-6k RPM, but this one is reporting 12-13k RPM. Chassis temperature is the same around 40C.
Any help is greatly appreciated.

On X9DRW motherboard you could tune fan speed with IPMI/BMC: e.g. using Supermicro IPMIView app, going to "IPMI device" tab, "Fan Speed Mode" section.
By default, "Standard" mode is selected (gives about 5000 rpm in my case). "Full" (about 12000 rpm) seems is what you're looking for.
