Cooling Overview (System Fan Speed) — ThinkSystem DA240 Enclosure only
The system fan speed is monitored in Cooling Overview. This section is only applicable to DA240 Enclosure, and is not applied to DW612 and DW612S Enclosure due to direct water-cooling system.
The system fan speed is displayed in RPM. Error log is asserted when the fan speed is below the lower critical threshold.

Faulty condition:
- Fan # Tach A(B):
The DA240 Enclosure system is equipped with dual-motor fans. Tach A displays the primary fan motor speed while Tach B displays the redundant fan motor speed.
System fan speed normally operates at higher than 1500 RPM for Tach A and Tach B.
Lower Critical: 768 RPM is set to be the lower critical fan speed threshold.
