Thermal Management
NOTE: If your system does not support thermal settings, then the Thermal Management feature is not available.
Dell Command | Power Manager allows you to manage your system’s processor and cooling fan settings so that you can manage
performance, system surface temperature, and fan noise. Each option represents a different balance of these three elements.
Choose the configuration that best suits the way you use your system.
CAUTION: If a fan has failed, the Thermal Management feature is disabled.
Setting Description

surface temperature. Your system may produce more noise
and experience reduced performance.

noise. This configuration may also reduce system performance
and raise system surface temperature.

produce higher system performance. This configuration
