janten Posted December 5, 2016 Share Posted December 5, 2016 For my EP2C602 the commands are slightly different. On this board, command 0x3a 0x01 works different: ipmitool raw 0x3a 0x01 CPU_1_OVERRIDE CPU_1 REAR_1 FRONT_1 FRONT_2 UNKNOWN So, only five fans can be set up and value 0x00 is just minimal speed, not automatic. Automatic speed can only be enabled for CPU_1 by setting CPU_1_OVERRIDE to 0 (in which case the CPU_1 value is ignored). So for 30% speed on all fans and CPU_1 auto speed: ipmitool raw 0x3a 0x01 0 30 30 30 30 30 CPU_2 can be controlled in the same way through another command, 0x3a 0x11 , which also controls two additional fans: ipmitool raw 0x3a 0x11 CPU_2_OVERRIDE CPU_2 UNKNOWN UNKNOWN ipmitool raw 0x3a 0x11 0 30 30 30 To get the current status of all fans, which also includes the current RPM of the CPU fans in auto mode: ipmitool raw 0x3a 0x02 ipmitool raw 0x3a 0x12 Quote Link to comment

Where'd you get it from? The current status command works for my board, which could be useful. Did you try the ipmi plugin? Looks like case fans could be controlled as it's currently written.
