ASUS Crosshair 1-5
1.3.2 ASUS Unique features
8-Phase Power Design
The ASUS 8-Phase Power Design prolongs CPU lifespan and keeps the system stable by
preventing high power stress to the CPU and power supply module. The design ensures high
efciency operation to generate less heat compared with conventional power solutions, thus
achieving cool system environment and making this motherboard ideal for overclocking.
Fanless Design
The ASUS fanless design allows multi-directional heat ow from major thermal
sources in the motherboard to lower overall system temperature, resulting in
quieter operation and longer system life. ASUS has devoted special efforts to
address the thermal issues across the motherboard, and most notably in the
following areas: CPU, power, VGA, Northbridge and Southbridge. The heat pipe,
heatsink, and strategic board layout were tailor made to dissipate heat in the most
efcient manner.
PEG Link Mode for two graphics cards
This feature enhances your PCI Express graphics card performance. It allows the
motherboard to automatically adjust the PCI Express graphics link mode to the
correct frequency based on the system conguration. Four additional settings are
available for overclocking the PEG Link Mode. See page 4-24 for details.
ASUS Two-slot thermal design
The motherboard is designed with one PCI slot
and one PCIEx4 slot placed between the PCI Express
x16 slots, allowing increased airow between the two PCI
Express x16 graphics cards. This special design permits more
room for ventilation, thus lowering the overall system
temperature.
AI NOS™ (Non-Delay Overclocking System)
ASUS Non-delay Overclocking System™ (NOS) is a technology that auto-detects
the CPU loading and dynamically overclocks the CPU speed only when needed.
