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.

Chapter 1
Introduction of P31 Express and ICH7 chipset based Motherboards
1-1 Features of Motherboard
The P31 Express and ICH7 chipset motherboard series are based on Intel P31 Express chipset and
ICH7 chipsets technology which supports the innovative 45nm and 65nm Quad-Core,
Dual-Core Intel® Core 2 Quad, Core 2 Duo (Code Name: Conroe) processors, 90nm
Dual-Core Intel® D Processor 8series (except Pentium® D Intel 805.) an 9 Series processors,
Pentium 4 and Celeron with Intel® Hyper-Threading Technology.
The P31 Express and ICH7 chipset Based motherboard series deliver the revolutionary levels
of performance enabling vivid, high-definition experiences and multi-tasking responsiveness
from state-of-the-art Intel dual-core and quad-core technologies. Through the high bandwidth
of dual channel DDR2 800 / 667MHz system memories which are expandable to 4GB and the
PCI Express interface for the latest graphics cards from both AMD and nVidea. The P31
Express and ICH7 chipset motherboard series are absolutely the ultimate solution for game
enthusiasts and applications, and it also meets the demanding usage of computing of gaming,
multimedia entertainment and business applications.
The INTEL P31 Express and ICH7 chipset motherboard series are embedded with ICH7
chipset of providing four serial ATA2 interface of 3.0 Gb / s data transfer rate for four serial
ATA devices. More over, the motherboard provides also extra 1 Ultra ATA interface for two
IDE devices of 100 MB / s data transfer rate .
The P31 Express and ICH7 chipset Based motherboard provides Gigabit LAN function by using
the RealTek 8111C PCI-E Gigabit LAN which supports 10M / 100M / 1Gbps data transfer
rate. Embedded 6-channel ALC662 HD CODEC is fully compatible with Sound Blaster Pro®
standards that offer you with the home cinema quality and absolutely software compatibility.
The P31 Express chipset Based motherboard series offer one PCI-Express x16 graphics slot
offering 4 Gbyte/sec data transfer rate at each relative direction which get 3.5 times of
bandwidth more than AGP8X and up to 8 Gbyte/sec concurrent bandwidth at full speed. Two
PCI Express x1 I/O slots offer 512Mbyte/sec concurrently, over 3.5 times more bandwidth
than PCI at 133Mbye/sec, tackling the most demanding multimedia tasks nowadays. Three
32-bit PCI slots guarantee the rich connectivity for the I/O of peripherals.
Embedded USB controllers as well as capability of expanding to 6 of USB2.0 functional ports
delivering 480Mb/s bandwidth of rich connectivity, these motherboards meet the future USB
demands which are also equipped with hardware monitor function on system to monitor and
protect your system and maintain your non-stop business computing.
Some special features---CPU Thermal Throttling/ CPU Smart Fan/ CPU Vcore
7-shift/G.P.I. Function/DIY Clear/WI-FI in this motherboard are designed for power user to
use the over-clocking function in more flexible ways. But please be caution that the
over-clocking may cause the fails in system reliabilities. 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

2
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 in 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 8 stages for the precisely over-clocking of extra
demanding computing performance.
G.P.I Function—(Green power indicator function)
The full name of G.P.I technology is Green Power Indicator technology, obviously
technology utilized to low power consumption. G.P.I is a technology with remarkable power
saving function.
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.
WI-FI Technology
WIFI--Full name is wireless Fidelity. It has been used in notebook, mobile phone, PDA,
digital cameras and Mobile Terminals widely. With WIFI. We do not need to worry about the
speed and high spending when we are dialing long-distance calls, browsing web pages,
receiving and sending E-mails, loading music, delivering digital photos.
