ASUS Xtreme Design - 24 Hybrid Phase Design*
ASUS True 16+3 Phase Power Design
Unprecedented Innovation with the Best Quality Component for Best Performance The groundbreaking 16+3 phase VRM design is brrought to the ASUS motherboards. 16+3 phase power design, 16-phase for vCore and extra 3-phase for Memory controller inside CPU, can provide the highest power efficiency, and hence generates less heat to effectively enhance the overclocking capability. With the high quality power components such as low RDS (on) MOSFETs, Ferrite core chokes with lower hysteresis loss and 100% Japan-made high quality conductive polymer capacitors, ASUS 16+3 phase VRM design also ensure longer component life and minimum power loss.
*24 Hybrid Phase = 16+3 Phase x T.Probe
Leading Active Cooling Technology The T.Probe microchip detects and balances power phase loads and temperatures real-time. With optimal power phase functions, components run cooler and extend system lifespan.

System Level Energy Saving The new ASUS EPU - the world´s first power saving engine, has been upgraded to a new six engine version, which provides total system power savings by detecting current PC loadings and intelligently moderating power in real-time. With auto phase switching for components (which includes the CPU, VGA card, memory, chipset, drives and system fan), the EPU automatically provides the most appropriate power usage via intelligent acceleration and overclocking - helping save power and money.
ASUS Quiet Thermal Solution
ASUS Fanless Design - Heat-pipe solution
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.
Active Quiet & Cool ASUS Fan Xpert intelligently allows users to adjust both the CPU and chassis fan speed according to different ambient temperature , which is caused by different climate conditions in different geographic regions and system loading.Built-in variety of useful profiles offer flexible controls of fan speed to achieve a quiet and cool environment.
Up to 20°C(36°F) Cooler - Stack Cool 3+
Effective Fanless Heat Dissipation at 0dB Stack Cool 3+ is a fanless cooling solution offered exclusively by ASUS. It effectively and noiselessly transfers heat generated by the critical components to the other side of the specially designed PCB (printed circuit board) for effective heat dissipation - making temperatures cooler by up to 20°C.
