Electrical safety
• To prevent electrical shock hazard, disconnect the power cable from the electrical
outlet before relocating the system.
• When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
• Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
• Seek professional assistance before using an adpater or extension cord. These
devices could interrupt the grounding circuit.
• Make sure that your power supply is set to the correct voltage in your area. If you are
not sure about the voltage of the electrical outlet you are using, contact your local
power company.
• If the power supply is broken, do not try to x it by yourself. Contact a qualied service
technician or your retailer.

Aesthetic Heat Pipe
The aesthetic heat pipe design effectively directs the heat generated by the chipsets to
the heatsink near the back I/O ports - where it can be carried away by existing airows
from the CPU or a bundled optional fan. This innovative and groundbreaking fanless
heat pipe design effectively lowers temperatures by up to 10°C without having lifetime
problems that a normal chipset fan has. Furthermore, it provides options for users to
install side-ow fans or a passive cooler. This Heat Pipe design is the most reliable
fanless thermal solution to date.
DO NOT uninstall the heat-pipe by yourself. Doing so may bend the tubing and affect the
heat dissipation performance.
