Figure 5-5: IEI CF-520 Cooling Kit
An IEI Socket LGA775 CPU cooling kit shown in Figure 5-5 can be purchased separately.
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 CF-520 heat sink. The thermal
paste between the CPU and the heat sink is important for optimum
heat dissipation.
To install the cooling kit, follow the instructions below.
Step 1: Place the cooling kit onto the socket LGA775 CPU . Make sure the CPU
cable can be properly routed when the cooling kit is installed.
Step 2: Properly align the cooling kit . Make sure the four spring screw fasteners can
pass through the pre-drilled holes on the PCB.
Step 3: Mount the cooling kit . Gently place the cooling kit on top of the CPU. Make
sure the four threaded screws on the corners of the cooling kit properly pass
through the predrilled holes on the bottom of the PCB.
Step 4: Secure the cooling kit . From the solder side of the PCB, align the support
bracket to the screw threads on heat sink that were inserted through the PCB
holes. (See Figure 5-6 )
