ipmi-fancontrol.service pins the fans to a fixed speed on start and hands control back to the BMC's automatic curve on stop, to quiet the chassis. BMC credentials are read from conf/ipmi-fancontrol.conf, resolved relative to the scripts themselves so the tree stays self-contained whether it is run from a checkout or from /opt/ergosteur. See conf/ipmi-fancontrol.conf.example. Use ipmitool -E rather than -P so the password is passed via the environment instead of argv, where any local user could read it out of ps. docker-idrac.sh is the alternative temperature-aware controller.
