Asus P5B Premium Vista Edition - Manual (Page 21)

ASUS P5B Premium 1-
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.
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.

ASUS Crystal Sound
This feature can enhance speech-centric applications like Skype, online game,
video conference and recording.
ASUS Array Mic
The Bundled Superbeam Array Microphone receives only the sound
coming from the reception cone and ignores the sounds coming from other
directions. This mechanism eliminates a large number of interferences,
including neighboring speakers and reverberations. It also uses advanced
de-reverberation techniques to reduce echo and minimize its effect on the
speech engine. This feature can enchance speech-centric applications like
Skype, online game, video conference, and recording. See page 5-38 for
details.
