Copper Heat Pipe: Lowers Temperatures by up to 16°C
The Pure Copper Heat Pipe design effectively directs the heat generated by the chipsets to the heatsink near the back I/O ports - where it can be carried away by existing airflow from the CPU or a bundled optional fan. This innovative and groundbreaking fanless heat pipe design effectively lowers temperatures by up to 16°C without having lifetime problems that a normal chipset fan has. Furthermore, it provides options for users to install side-flow fans or a passive cooler. This Heat Pipe design is the most reliable fanless thermal solution to date.

Q-Fan 2: Adjusts both CPU fan and chassis fan speeds according to system loading
ASUS Q-Fan2 technology intelligently adjusts both CPU fan and chassis fan speeds according to system loading to ensure quiet, cool and efficient operation.

Q-Connector: Make connection quick and accurate!
