Cooling Solutions
As processor technology pushes to faster speeds and higher performance with increasing operation
clock, thermal management becomes increasingly crucial while building computer systems. Maintaining
the proper computing environment without thermal increasing is the key to reliable, stable, and 24
hours system operation. The overall goal is keeping the processor below its specified maximum case
temperature. Heatsinks induce improved processor heat dissipation through increasing surface area
and concentrated airflow from attached active cooling fans. In addition, interface materials allow
effective transfers of heat from the processor to the heatsink. For optimum heat transfer, AMD
recommends the use of thermal grease and mounting clips to attach the heatsink to the processor.
Please refer to the website below for collection of heatsinks evaluated and recommended for
Socket-AM2+ processors by AMD. In addition, this collection is not intended to be a comprehensive
listing of all heatsinks that support Socket-AM2+ processors.

Some special features---CPU Thermal Throttling/ CPU Vcore 7-shift/ CPU Smart Fan
／
OC-CON/G.P.I Function 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 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. (For detail operating please read Section 3-11 Bi-turbo
Configuration)
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 steps for the precisely over-clocking of extra
demanding computing performance.
OC-CON ---（High-polymer Solid Electrolysis Aluminum Capacitors）
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.

2-6-1 Connectors
(1) Power Connector (24-pin block) : ATXPWR1
ATX Power Supply connector. This is a new defined 24-pins connector that usually
comes with ATX case. The ATX Power Supply allows to use soft power on momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on the
motherboard. When the power switch on the back of the ATX power supply turned on,
the full power will not come into the system board until the front panel switch is
momentarily pressed. Press this switch again will turn off the power to the system
board.
** We recommend that you use an ATX 12V Specification 2.0-compliant power supply
unit (PSU) with a minimum of 350W power rating. This type has 24-pin and 4-pin
power plugs.
** If you intend to use a PSU with 20-pin and 4-pin power plugs, make sure that the 20-pin
power plug can provide at least 15A on +12V and the power supply unit has a minimum
power rating of 350W. The system may become unstable or may not boot up if the
power is inadequate.
