Service

Purpose: Noctua-safe IPMI fan thresholds at boot

Systemd oneshot service that lowers IPMI fan sensor thresholds to 50 RPM at boot. All case fans are Noctua units that idle at 280-500 RPM — well below SuperMicro's default Lower Critical threshold, which triggers false alerts and fan cycling. Also clears the BMC System Event Log to prevent duty cycle lockup from SEL overflow.
