System Cooling
There are three 4-cm counter-rotating fans (with option for three more) that provide 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. These fans are secured to the chassis without using any
screws, for easy replacement or upgrades. Simply drop them in, plug the cable and secure
the chassis cover.
Make sure the chassis top cover makes a good seal so the cooling air circulates properly
through the chassis.
