# Fan Control

By default, the aCMM-2000 controls the fan tray modules at regular speed (Fan Level 8). The aCMM-2000 detects and adjusts the fans' speed based on two temperature sensors located inside the chassis.

<table><tr><td>Criteria</td><td>Fan Level</td></tr><tr><td>Lower than 30°C</td><td>8</td></tr><tr><td>Higher than 30°C</td><td>12</td></tr><tr><td>Higher than 40°C</td><td>15</td></tr></table>

# Thermal Couple

The aTCA-8505 Series integrates two thermal couples located internally on the left and right side of the chassis cabinet. The aCMM-2000 can detect these sensors and automatically adjust fan speed to its proper level.
