AI Gear2 allows users to choose profiles to adjust CPU frequency and vCore voltage to
minimize system noise and power consumption. For example, users can change the mode in
real-time in the operating system to max power saving mode and can up to 50% power for the
CPU when using word processing applications.
Fanless Design - Heat Pipe
Zero failure
Support side-flow fan or passive cooler
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.
