      Fanless Design
      Provide a cool environment without all the baggage
      Cooling fans, though a popular thermal solution, also come with noise and malfunction likelyhood. ASUS Motherboard´s fansless concept is specifically created to provide a cool environment without all the baggage.

      ASUS has devoted special efforts to address the thermal issues across the motherboard, and most notably the areas that reside the CPU, power, VGA, and chipsets. The heat sinks were tailor made to dissipate heat in the most efficient manner.


      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.

      Optional Fan (for Water-Cooling or Passive-Cooling only)
      Maximize Water-Cooling or Passive-Cooling performance!
      The optional fan is specifically designed to provide sufficient airflow over the chipset area and CPU power modules when water-cooling or passive-cooling is utilized, ensuring effective heat dissipation for the entire system.

      Uses 100% All High-quality Conductive Polymer Capacitors!
      This motherboard uses all high-quality conductive polymer capacitors onboard for durability, improved lifespan, and enhanced thermal capacity.


      ASUS EZ DIY

      Q-Shield

      Easy and Comfortable Installations
      The specially designed ASUS Q-Shield does without the usual "fingers" - making it convenient and easy to install. With better electric conductivity, it ideally protects your motherboard against static electricity and shields it against Electronic Magnetic Interference (EMI).

      AI Direct Link
      Lightning Fast Data Linkage between Your PC & Laptop AI Direct Link can easily and efficiently transfer large amounts of data via the network cable - saving up to 70% of the total time taken. With AI Direct Link, it becomes easy to backup or share large data files like movies or other media content.

      Q-Connector
      Make connection quick and accurate!
      The ASUS Q-Connector allows you to connect or disconnect chassis front panel cables in one easy step with one complete module. This unique adapter eliminates the trouble of plugging in one cable at a time, making connection quick and accurate.

      CrashFree BIOS 2
      The CrashFree BIOS2 feature now includes the BIOS auto-recovery function in a support CD. Users can reboot their system through the support CD when a bootable disk is not available,
      and go through the simple BIOS auto-recovery process. ASUS motherboards now enable users to enjoy this protection feature without the need to pay for an optional ROM.

      O.C. Profile
      Conveniently store or load multiple BIOS settings
      Freely share and distribute favorite overclocking settings

      The motherboard features the ASUS O.C. Profile that allows users to conveniently store or load multiple BIOS settings. The BIOS settings can be stored in the CMOS or a separate file, giving users freedom to share and distribute their favorite overclocking settings.
