Every board in the X9DRW series should have a BMC with IPMI, and this is what controls your fans and other sensors. Plug in the management port (but not to a public or hostile network!) and if these settings haven’t been changed, you can go to <http://<IP address from DHCP>> and log in with “ADMIN” and “ADMIN” (case sensitive, no quotes). >From there, go to “Configuration” > “Fan Speed Mode” and change “Full Speed Mode” to “Standard Mode” or “Optimal Mode”. You can do this over IPMI. Install sysutils/ipmitool. I don’t think the tool works with ipmi(4), so you’ll need to do this from one of your real interfaces to the management interface. Try this: # ipmitool -I lanplus -H <BMC name/IP> -U <username> -P <password> \ raw 0x30 0x45 0 If it works, you’ll see one of the following values: > 0 = Standard > 1 = Full > 2 = Optimal? > 3 = Minimal? > 4 = HeavyIO? Change the mode with this: # ipmitool [...] -P <password> raw 0x30 0x45 1 <new value> I have a Supermicro board, but it doesn’t run OpenBSD and I haven’t touched IPMI for some months now, so this guide might not be perfect.
