Warning:
1. Attach the CPU and heatsink using silica gel to ensure full contact.
2. It is suggested to select high-quality, certified fans in order to avoid
damage to the motherboard and CPU due to high temperatures.
3. Never turn on the machine if the CPU fan is not properly installed.
4. Ensure that the DC power supply is turned off before inserting or
removing expansion cards or other peripherals, especially when
you insert or remove a memory module. Failure to switch off the DC
power supply may result in serious damage to your system or
memory module.
Warning:
We cannot guarantee that your system will operate normally while
over-clocked. Normal operation depends on the over-clock capacity of
your device.
Attention:
Since BIOS programs are upgraded from time to time, the BIOS
description in this manual is just for reference. We do not guarantee
that the content of this manual will remain consistent with the actual

Notes:
Take note of the following precautions before you install compo-
nents or change settings.
1. Use a grounded wrist strap or touch a safely grounded object,
such as an attached power supply, before handling compo-
nents to avoid damaging them due to static electricity.
2. Unplug the power cord before opening your chassis or touching
any component.
3. Hold components by their edges to avoid touching any exposed
integrated circuits (ICs).
4. Whenever you uninstall a component, place it on a grounded
anti-static pad or into anti-static bag that it came in.

Chapter 2 Installation Instructions
Installation of CPU Fan
New technology allows processors to run at higher and higher frequencies.
To avoid problems arising from high-speed operation, for example, overheating,
you need to install the proper fan. The following procedures are provided
for reference only, please refer to your CPU fan user guide to install it.
1. Locate the CPU retention mechanism
base (surrounds the CPU socket).
3. Attach the fan to the base.
2. If required, apply a light coating
of silica gel to the top of the CPU.
Note: The CPU heatsink may have a
pre-applied thermal compound. In that
case, the silica gel is not required.
4. Connect the power fan’s power
cable to the appropriate 3-pin
connector on the motherboard.
Warning :
Excessive temperatures will severely damage the CPU and
system. Therefore, make sure that the cooling fan works normally
at all times in order to prevent overheating and damaging to the
CPU.

Attention:
1.Position the fan with the retention mechanism on top of the
heatsink. Align and snap the four hooks of the retention
mechanism to the holes on each corner of the module base.
2.Make sure that the fan and retention mechanism assembly
perfectly fits the heatsink and module base, otherwise you
cannot snap the hooks into the holes.
