    Supermicro X9/X10/X11 Fan Speed Control

    Setting up IPMI fan control mode, or fan thresholds are persistent configurations. If you configured once they will stay while the BMC is not reset. If you want to have a dynamic fan speed control based on temperature then use can use a script (it must be executed locally, and be running...

    Supermicro X9/X10/X11 Fan Speed Control

    Those scripts were created for local execution indeed, but you can hack ESXi with ipmitool remote access if you really want to. You may also google any existing solution for ESXi: ipmitool 1.8.11 vib for ESXi Fan Control for Dell Server in ESXI

    Supermicro X9/X10/X11 Fan Speed Control

    You may use ipmitool remotely since IPMI/BMC is an independent subsystem. You can configure things from a different Windows or Linux PC. You need the IP address for the BMC interface and ADMIN credentials.

    Supermicro X9/X10/X11 Fan Speed Control

    You may read the very first post in this thread for better understanding. In the user manual (on page 13) there is also a reference on this: FAN1 ~ FAN4 FANA, FANB CPU/System Fan Headers

    Supermicro X9/X10/X11 Fan Speed Control

    Ofc, you can use splitters for your fans. In the definition of the Super Micro IPMI modes: On these boards there are 4 levels of speed control: Standard: BMC control of both fan zones, with CPU zone based on CPU temp (target speed 50%) and Peripheral zone based on PCH temp (target speed 50%)...

    Supermicro X9/X10/X11 Fan Speed Control

    Interestingly I got threshold problems in low temperature situations (with an open window winter time) in the past, meaning the the fan reached the lower threshold value. Some fellows are using Optimal mode and let the system find the proper fan rotation speed, like in this case. I prefer Full...

    Supermicro X9/X10/X11 Fan Speed Control

    Fan controlling in both zones (CPU and HD) can be switched on and off independently. But the FANs in the zones defined by IPMI and it cannot be changed AFAIK. When you control CPU zone all FAN1-FAN4 fans will change their rotation speed (and same goes for HD zone with FANA-FANB).

    Supermicro X9/X10/X11 Fan Speed Control

    Based on several references and projects (on this site, on TrueNAS forums, and on different blogs) I just created a systemd service for Linux to control my fans through IPMI on my Super Micro X11SCH-F motherboard. This service switches to FULL fan mode and can control the fans based on...
