8-Phase Power Design The ASUS 8-Phase Power Design provides highly efficient operation to generate less heat (at least 15°C (59°F)) than other conventional power solutions. It reduces input ripple current and output ripple voltage, which keeps CPU and power module from suffering the risk of high power stress. It has the advantages of quick transient response and stability, especially beneficial when CPU requires more current immediately under heavy loading or overclocking mode. DO NOT uninstall the heat-pipe by yourself. Doing so may bend the tubing and affect the heat dissipation performance. Fanless Design - Stack Cool 2 ASUS Stack Cool 2 is a fan-less and zero-noise cooling solution that lowers the temperature of critical heat generating components. The motherboard uses a special design on the printed circuit board (PCB) to dissipate heat these critical components generate. Fanless Design - Heat-pipe 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 airflow 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-flow fan or passive cooler. The Heat Pipe design is the most reliable fanless thermal solution to date. Q-Fan 2 ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis fan speeds according to system loading to ensure quiet, cool and efficient operation. See page 4-29 and 5-23 for details.

generate less heat (at least 15°C (59°F)) than other conventional power

keeps CPU and power module from suffering the risk of high power stress.
It has the advantages of quick transient response and stability, especially
beneficial when CPU requires more current immediately under heavy loading
or overclocking mode.
DO NOT uninstall the heat-pipe by yourself. Doing so may bend the tubing and
affect the heat dissipation performance.
Fanless Design - Stack Cool 2
ASUS Stack Cool 2 is a fan-less and zero-noise cooling solution that lowers
the temperature of critical heat generating components. The motherboard
uses a special design on the printed circuit board (PCB) to dissipate heat
these critical components generate.
Fanless Design - Heat-pipe
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
airflow 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-flow fan or passive cooler. The Heat
Pipe design is the most reliable fanless thermal solution to date.
Q-Fan 2
ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis fan
speeds according to system loading to ensure quiet, cool and efficient operation.
