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—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
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.
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.
ASUS Crystal Sound
This feature can enhance speech-centric applications like Skype, online game,
video conference and recording.
Noise Filtering
This feature detects repetitive and stationary noises (non-voice signals) like
computer fans, air conditioners, and other background noises then eliminates
it in the incoming audio stream while 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 multi-channels allows you to
experience true-to-life high quality audio.
