      8 Phase Power Design

      Cooler and quieter system
      Longer components lifespan
      More stable and reliable under heavy-loading and overclocking


      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
      Effective and zero-noise heat dissipation
      Stack Cool 2 is a fan-less and zero-noise cooling solution offered exclusively by ASUS. It effectively transfers heat generated by the critical components to the other side of the specially designed PCB (printed circuit board) for effective heat dissipation.

      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.

      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.
