Fans

Strategically located fans, combined with efficient airflow paths, provide highly effective system cooling for the x3455. The server includes three temperature-controlled fans that adjust to compensate for changing thermal characteristics, depending on the zone and internal temperatures. At the lower speeds they draw less power and suffer less wear. Equally important in a crowded data center, temperature-controlled fans produce less ambient noise in the data center than if they were constantly running at full speed. In addition, the power supply contains two fans.
