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.
For vendor list of heatsinks and Active cooling fans, please visit AMD official website.

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)

This motherboard provides a 940-pin surface mount, Zero Insertion Force (ZIF)
socket, referred to as the mPGA940 socket supports AMD AM2+ processor in the 940
Pin package utilizes Flip-Chip Pin Grid Array 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
heatsink 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 ZIF
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.

(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 using 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.
(2) ATX 12V Power Connector (8-pin block) : ATX12V
This is a new defined 8-pins connector that usually comes with ATX Power
Supply. The ATX Power Supply which fully supports Socket AM2+ processor
must including this connector for support extra 12V voltage to maintain system
power consumption. Without this connector might cause system unstable
because the power supply can not provide sufficient current for system.
