Set the Global temp setting to control all 4 fans together or set individual temp profiles for each fan. Summary: This article shows how to modify the PowerEdge Server Thermal settings and Fan Speed manually. To modify the thermal settings: In the iDRAC Web interface, go to Configuration > System Settings > Hardware Settings > Cooling. Dell PowerEdge servers include proprietary thermal controls that automatically manage server component temperatures. Dell PowerEdge controls use sensor monitoring and knowledge of the specific hardware that is installed on the system to minimize fan speeds, airflow, and power consumption without. Where to place the temperature sensor? At the rack's intake, monitoring external ambient temp? At the server's intake, monitoring server's "ambient" temp (external ambient plus recirculated hot air that didn't get expelled quickly enough)? At the server's exhaust, monitoring server's "ambient" temp. Where to place the temperature sensor? At the rack's intake, monitoring external ambient temp?
