No, Supermicro is using a 9 cm thermal controlled fan together with an air box that provides 65% of the airflow over the SATA hard drives, 25% over the Add-on cards and 15% for the memory, that together with a 12cm also Thermal controlled low noise Exhaust fan provides a perfect airflow to carry off the dissipated heat. The 450-Watt powersupply is thermal and power loaded controlled combined that with the controlled airflow is a perfect combination for a low noise and thermal controlled solution.
