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.

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 in working.
Debug Port--- ( The Professional Hardware Diagnosis System )
Being bugged of abnormal system failure through the tossed and turned nights no more, the
embedded Hardware Debug Port offers you the real-time visual system healthy for the
demanding usage of computing. No more bugging by unknown system failure and no more
time wasted in the first moment of 24-hour nonstop ping business computing, the embedded
Debug Port will turn you into a well training hardware professional with the seeing system
situation. (The Post Code please refer Appendix)
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 7-Shift--- ( Shift to Higher Performance )
The CPU voltage can be adjusted up by 8 stages for the precisely over-clocking of extra
demanding computing performance.

2-3-2 About Intel Pentium 4 LGA775 CPU
This motherboard provides a 775-pin surface mount, LGA775 Land Grid Array socket,
referred to as the LGA775 socket supports Intel Pentium 4 processor in the 775 Pin package
utilizes Flip-Chip Land Grid Array (FC-LGA4) package technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent
overheating. If this is not the case, then purchase a correct cooling FAN before you turn on
your system.
WARNING! Be sure that there is sufficient air circulation across the processor’s heat
sink and CPU cooling FAN is working correctly, otherwise it may cause
the processor and motherboard overheat and damage, you may install an
auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the LGA775
socket and open it by first pulling the level sideways away from the socket then upward to a
90-degree angle. Insert the CPU with the correct orientation as shown below. The notched
corner should point toward the end of the level. Because the CPU has a corner pin for two
of the four corners, the CPU will only fit in the orientation as shown.
