4.4.2 Socket G1 Cooling Kit Installation
An IEI Socket G1 CPU cooling kit can be purchased separately. (See Chapter 3 ) The
cooling kit comprises a CPU heat sink and a cooling fan.
WARNING:
Do not wipe off (accidentally or otherwise) the pre-sprayed layer of
thermal paste on the bottom of the heat sink. The thermal paste
between the CPU and the heat sink is important for optimum heat
dissipation.
To install the cooling kit, please follow the steps below.
Step 1: Install the cooling kit bracket . A cooling kit bracket is installed on the rear of
the motherboard. Align the bracket with the four retention holes at the back of
the motherboard. Once properly aligned, insert four retention screws from the
front of the motherboard.
