Supermicro MOBO, fan speed profile

[jebusfreek666]

I have to set my fan speed profile to optimal after each start-up/reboot. Each time it change back to full speed. Does anyone know how to make the change persistent? I'm already tired of going into ipmi every time I turn on the server.

 Supermicro X11SSM-F. I have had it for about 3 years or so I think.

you have a new generation MB, so i don't think it CMOS.. have you tried a BMC/BIOS update if available?

I'd check the CMOS battery. From the manual of your mobo:

 

Losing the System's Setup Configuration

1. Make sure that you are using a high-quality power supply. A poor-quality power supply
may cause the system to lose the CMOS setup information. Refer to Chapter 2 for
details on recommended power supplies.
2. The battery on your motherboard may be old. Check to verify that it still supplies
~3VDC. If it does not, replace it with a new one.
3. If the above steps do not fix the setup configuration problem, contact your vendor for
repairs.
