Which fan headers are you using for what fans?Hello everybody.
I'm still very new to the FreeNAS world.
I'm setting up a FreeNAS box in my living room so I want it to be whisper quiet and thought a script such as Stux's or Kevin Horton's mod could help tremendously, but unfortunately neither of the two works as expected on my machine.
Could it be because I'm using a Supermicro X11 board (X11SSM-F)?
This is what I get when I run Stux's script at debug level 1:
Code:root@FreeNAS:~ # ./hybrid_fan_controller.pl 2017-07-07 12:40:56: CPU Temp: 36.0 <= 36, CPU Fan going low. 2017-07-07 12:40:57: Maximum HD Temperature: 37 2017-07-07 12:40:57: Drives are warm, going to 80% 2017-07-07 12:41:09: CPU fan speed should be low, but 2000 > 1600. 2017-07-07 12:41:26: CPU fan speed should be low, but 2000 > 1600. 2017-07-07 12:41:31: Resetting BMC
If I understand correctly, the BMC is ignoring the ipmitools commands to lower fan speeds (CPU fan speed should be low, but 2000 > 1600) even after being reset.
Do you have any ideas how I could fix this? Thank you!
First thing you should check is using your IPMI set the fanmode to standard/optimal and verify that your fans do actually slow down. You need PWM fans for them to be controllable.
