ASUS P5B Deluxe 1-
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.
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
2-37 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 page4-23 and 5-22 for details.
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 5-28 for
details.
Noise Filter
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. See page 5-28 for details.
