2-3 Mounting the Motherboard in the Chassis
All motherboards have standard mounting holes to fi t different types of chassis.
Make sure the location of all the mounting holes for both the motherboard and the
chassis match. Although a chassis may have both plastic and metal mounting fas-
teners, metal ones are highly recommended because they ground the motherboard
to the chassis. Make sure 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
necessary precautionary measures to prevent damage done to these components
when installing the motherboard into the chassis.)
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 turn it counterclock-
wise to make a 1/4 (90
0
) turn, and then pull
the fastener upward to loosen it.
4. Repeat Step 3 to loosen all fasteners
from the mounting holes.
5. With all fasteners loosened, remove the
heatsink from the CPU.
