2-3 Mounting the Motherboard in the Chassis
All motherboards have standard mounting holes to fi t different types of chassis.
Make sure that the locations of all the mounting holes for both the motherboard and
the chassis match. Although a chassis may have both plastic and metal mounting
fasteners, metal ones are highly recommended because they ground the mother-
board to the chassis. Make sure that the metal standoffs click in or are screwed in
tightly. Then, use a screwdriver to secure the motherboard onto the motherboard
tray. (Note: Some components are very close to the mounting holes. Please take
all precautionary measures to prevent damage done to these components when
you install the motherboard into the chassis.)
Heatsink Removal
8. Repeat Step 6 to insert all four heatsink
fasteners into the mounting holes.
9. Once all four fasteners are securely
inserted into the mounting holes and the
heatsink is properly installed on the moth-
erboard, connect the heatsink fan wires to
the CPU Fan connector.
1. Unplug the power cord from the power
supply.
2. Disconnect the heatsink fan wires from the
CPU fan header.
3. Use your fi nger tips to gently press on the
fastener cap and rotate counterclockwise to
make a 1/4 (90
0
) turn.
4. Repeat Step 3 to loosen all fasteners from
the mounting holes.
5. With all fasteners loosened, remove the
heatsink from the CPU.
