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.
