5.6 Thermal
The thermal design of the PowerEdge R210 reflects the following:
• Closed loop thermal control algorithm. Closed loop thermal control
method uses feedback temperatures to dynamically determine proper fan
speeds.
• Comprehensive thermal management. The PowerEdge R210 controls
system cooling fan speed based on several different responses from critical
components’ sensors, such as CPU temperature, DIMM temperature, inlet
ambient temperature, and system configurations. The thermal management
adjusts proper cooling ability for the system according to what the system
really needs.
