The iDRAC stock curve runs the CPU at ~72°C on the 7080 RPM floor even under load (optimises for quiet, not cool). Add a bash daemon + systemd unit that drives the chassis fans from CPU temp on two curves, picked by garage occupancy (the server is in the garage): COOL when empty (measured ~58-65°C under load), QUIET near the silent floor when the ha-sofia garage door shows someone is there (open, or <15min since last activity). Manual fan mode is backstopped: bash EXIT trap + systemd ExecStopPost hand fans back to Dell auto on stop/crash; CPU>=83°C or repeated IPMI failures do the same. Pushgateway metrics (job=fan_control). 36 unit tests cover the pure curve/hysteresis/presence/parse logic; DRY_RUN + RUN_ONCE for integration checks. Deployed and verified on 192.168.1.127 (CPU 70->58°C in cool mode, hysteresis stepping confirmed).
