Environmental Safety Instruction
zAvoid the dusty, humidity and temperature extremes. Do not place the product in
any area where it may become wet.
z0 to 40 centigrade is the suitable temperature. (The figure comes from the request
of the main chipset).
zGenerally speaking, dramatic changes in temperature may lead to contact
malfunction and crackles due to constant thermal expansion and contraction from
the welding spots’ that connect components and PCB. Computer should go
through an adaptive phase before it boots when it is moved from a cold
environment to a warmer one to avoid condensation phenomenon. These water
drops attached on PCB or the surface of the components can bring about
phenomena as minor as computer instability resulted from corrosion and oxidation
from components and PCB or as major as short circuit that can burn the
components. Suggest starting the computer until the temperature goes up.
zThe increasing temperature of the capacitor may decrease the life of computer.
Using the close case may decrease the life of other device because the higher
temperature in the inner of the case.
zAttention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.

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.

2-3-2 About Intel LGA 1156 CPU Socket
This motherboard provides an 1156-pin DIP, LGA 1156 Land Grid Array socket,
referred to as the LGA 1156 socket.
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.
NOTED! 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 LGA
1156 socket and open it by first pulling the level sideways away from the socket then
upward to a 135-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.
When you install the CPU into the LGA 1156 socket, there’s no force required CPU
insertion; then press the level to locate position slightly without any extra force.

2-6 Connectors, Headers
2-6-1 Connectors
(1) Power Connector (24-pin block): ATXPWR
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.
