Fans, Ventilation, and Airflow

The chassis temperature is regulated with internal fans. Onboard sensors control the fan speed. The fans are
always on when the device is powered on. Under all conditions, the fans operate at the slowest speed possible
to conserve power and reduce noise. When necessary, the fans operate at higher speeds for different
environmental conditions.
