Even though this is a large and powerful unit, the fan is very quiet. Even when under load the unit make virtually no noise. This is great for those that that are looking to build a quiet gaming system. On top of this the unit knows when it needs to turn the fan on (which is even customizable through a cable that connects the unit to the motherboard for fan control) meaning it will only be in use when under load.
Pro Uses a pull tech for power supply
When plugged in the unit will use zero power, it is only when something needs to draw power from it that it will finally output power.
