Cooling Solutions
As processor technology pushes to faster speeds and higher performance, thermal management
becomes increasingly crucial while building computer systems. Maintaining the proper thermal
environment is the key to reliable, long-term system operation. The overall goal in providing the
proper thermal environment is keeping the processor below its specified maximum case temperature.
Heat sinks induce improved processor heat dissipation through increased surface area and
concentrated airflow from attached fans. In addition, interface materials allow effective transfers of
heat from the processor to the heat sink. For optimum heat transfer, Intel recommends the use of
thermal grease and mounting clips to attach the heat sink to the processor.
When selecting a thermal solution for your system, please refer to the website below for collection of
heat sinks evaluated and recommended by Intel for use with Intel processors. Note, those heat sinks
are recommended for maintaining the specified Maximum T case requirement. In addition, this
collection is not intended to be a comprehensive listing of all heat sinks that support Intel processors.

DIY Clear/OC-CON /G.P.I. Function/WI-FI Technology
CPU Thermal Throttling/ CPU Smart Fan/ CPU Vcore X-shift/
in this motherboard are designed
for power user to use the over-clocking function in more flexible ways. But please be caution
1
that the over-clocking may cause the failure in system reliability. This motherboard provides
the guaranteed performance and meets the demands of the next generation computing. But if
you insist to gain more system performance with variety possibilities of the components you
choose, please be careful and make sure to read the detailed descriptions of these value added
product features, please get them in the coming section.
1-1.1 Special Features of motherboard
CPU Thermal Throttling Technology--- (The CPU Overheat Protection Technology)
To prevent the increasing heat from damage of CPU or accidental shutdown while at high
workload, the CPU Thermal Throttling Technology will force CPU to enter partially idle
mode from 87.5% to 12.5% according to preset CPU operating temperature in BIOS (from 40
℃ to 90℃). When the system senses the CPU operating temperature reaching the preset
value, the CPU operating bandwidth will be decreased to the preset idle percentage to cool
down the processor. When at throttling mode the beeper sound can be optionally selected to
indicate it is working.
CPU Smart Fan--- The Noise Management System
It’s never been a good idea to gain the performance of your system by sacrificing its acoustics.
CPU Smart Fan Noise Management System is the answer to control the noise level needed for
now-a-day’s high performance computing system. The system will automatically increase the
fan speed when CPU operating loading is high, after the CPU is in normal operating condition,
the system will low down the fan speed for the silent operating environment. The system can
provide the much longer life cycle for both CPU and the system fans for game use and
business requirements.
CPU Vcore X-Shift--- Shift to Higher Performance
The CPU voltage can be adjusted up by 64 stages for the precisely over-clocking of extra
demanding computing performance.
DIY Clear
The CMOS Button is to facilitate the clear COMS process for power user overclocking
function. The user can easily clear or restore COMS settings by pressing down the button,
without taking trouble to remove the case and locate the jumper for clear CMOS.
OC-CON---High-polymer Solid Electrolysis Aluminum Capacitors (Optional, for HI04
series only)
The working temperature is from 55 degrees Centigrade below zero to 125 degrees
Centigrade, OC-CON capacitors possess superior physical characteristics that can be while
reducing the working temperature between 20 degrees Centigrade each time, intact extension
10 times of effective product operation lives, at not rising degrees Centigrade of working
temperatures each time a relative one, life of product decline 10% only too.
G.P.I Function—(Green power indicator function)
