Hardware Installation
• Be sure to connect fan cables to the fan headers to prevent your CPU and system from
overheating. Overheating may result in damage to the CPU or the system may hang.

fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed
inside the chassis.
