1-6 Chapter 1: Product Introduction
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 - Pure Copper 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.
DO NOT uninstall the heat-pipe by yourself. Doing so may bend the tubing and
affect the heat dissipation performance.
Optional Fan (for Water-Cooling or Passive-Cooling only)
The optional fan is specifically designed to provide sufficient airflow over the
CPU power modules and chipset area when water-cooling or passive-cooling
is utilized, ensuring effective heat dissipation for the entire system. See page
2-36 for details.
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 pages 4-32 and 5-23 for details.
ASUS Crystal Sound
This feature can enhance speech-centric applications like Skype, online game,
video conference and recording.
AI Audio 2
AI Audio 2 creates a virtual center channel that expands the overall sound
field without introducing a picket fencing effect. Preserving the dialogue or
solo performances with downmixing from multichannels will allow you to
experience true-to-life high quality audio. See pages 5-27 to 5-35 for details.
