System Cooling
Six 4-cm counter-rotating fans provide the cooling for the system. Each fan unit is actually
made up of two fans joined back-to-back, which rotate in opposite directions. This counter-
rotating action generates exceptional airflow and works to dampen vibration levels.
Make sure the chassis top cover makes a good seal so the cooling air circulates properly
through the chassis.
