ASUS Xtreme Phase
ASUS True 16+2 Phase Power Design
The groundbreaking 16+2 phase VRM design is brought to the ASUS motherboards.
16+2 phase power design, 16-phase for vCore and extra 2-phase for QPI/Memory
controller inside CPU, can provide the highest power efciency, and hence generates
less heat to effectively enhance the overclocking capability. With the high quality power
components such as low RDS (on) MOSFETs, Ferrite core chokes with lower hysteresis
loss, and 100% high quality conductive polymer capacitors, ASUS 16+2 phase VRM
design also ensure longer component life and minimum power loss.
ASUS Exclusive Features

components in real-time–helping save power and money! Refer to page 4-5 for details.
Express Gate
Express Gate™ is an ASUS exclusive OS that provides you with quick access to the
Internet and key applications before entering the Windows®OS. Refer to page 3-35
and 4-8 for details.
ASUS Quiet Thermal Solutions
ASUS Quiet Thermal solutions make the system more stable and enhance the overclocking
capability.
Fanless Design—Heat-pipe solution
The Heat Pipe design effectively directs the heat generated by the chipsets to the
heatsink near the back IO ports, where it can be carried away by existing airow from
CPU fan or bundled optional fan. The purpose of the innovative heat pipe design on
this motherboard is that the groundbreaking fanless design does not have lifetime
problems as a chipset fan does. Furthermore, it provides options for users to install
side-ow fan or passive cooler. The 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.

Up to 20ºC (36ºF) Cooler—Stack Cool 3+
Stack Cool 3+ is a fanless cooling solution offered exclusively by ASUS. It effectively
and noiselessly transfers heat generated by the critical components to the other side
of the specially designed PCB (printed circuit board) for effective heat dissipation—
making temperatures cooler by up to 20ºC.
Fan Xpert
ASUS Fan Xpert intelligently allows you to adjust both the CPU and chassis fan speeds
according to different ambient temperatures caused by different climate conditions
in different geographic regions and your PC’s loading. The built-in variety of useful
proles offer exible controls of fan speed to achieve a quiet and cool environment.
